Enterprise LLM selection criteria: security, licensing, cost, scalability, and governance.

What Makes an LLM Enterprise-Ready?

Choosing an LLM for enterprise AI is very different from choosing a model for casual experimentation.

A developer may care mostly about answer quality and speed.

An enterprise also needs to consider:

  • Security
  • Data privacy
  • Licensing
  • Scalability
  • Reliability
  • Infrastructure
  • Governance
  • Integration
  • Total cost of ownership

A model can perform extremely well and still be a poor enterprise choice if it is difficult to deploy, expensive to operate, or unsuitable for the company's data requirements.

The most useful enterprise evaluation therefore combines model capability and operational practicality.

Enterprise Factor What to Evaluate
Reasoning Complex business and technical tasks
Coding Developer productivity
RAG Enterprise knowledge retrieval
Agents Multi‑step automation
Context Documents and repositories
Multilingual Global business operations
Security Data and access controls
Licensing Commercial rights and restrictions
Deployment API, private cloud, self‑hosting
Cost Infrastructure and inference economics
Reliability Latency, uptime, failure handling
Governance Monitoring, auditability, policy

Open-Source vs Open-Weight for Enterprise AI

This distinction is particularly important for businesses.

An AI model may be available as:

  • Open source
  • Open weight
  • Source available
  • Commercially licensed
  • Research-only
  • Custom licensed

These categories should not be treated as identical.

For example, Qwen3 states that its open-weight models are licensed under Apache 2.0. GLM-5's repository uses Apache 2.0. Gemma 4 is also released under Apache 2.0 according to Google. Llama, by contrast, uses its own model license and acceptable-use framework rather than simply Apache 2.0 or MIT. 

That means enterprise teams should always review the exact model and version before deployment.

The Leading Enterprise Open-Model Shortlist

For a new enterprise AI project, the strongest initial shortlist should include:

  • Qwen
  • DeepSeek
  • GLM
  • Llama
  • Mistral
  • Gemma

Additional models such as Kimi and MiniMax may become relevant for specific use cases.

The objective is not to create a permanent ranking.

Instead, each model should be evaluated against the enterprise workload.

Mistral Enterprise Strengths

Mistral is especially relevant for:

  • Enterprise RAG
  • Coding
  • Multimodal applications
  • Private inference
  • European data and deployment requirements
  • Hybrid cloud environments

The current lineup includes Mistral Small 4 under Apache 2.0 and Mistral Medium 3.5 under a modified MIT license, so the exact model license should be reviewed before commercial adoption. 

Enterprise verdict

Mistral is a strong option for enterprises that want a mix of open-weight models and managed enterprise deployment.

Gemma for Enterprise AI

Gemma is Google's open-weight model family and is particularly attractive for organizations that need capable models across different hardware sizes.

The current Gemma 4 family is designed around:

  • Advanced reasoning
  • Agentic workflows
  • Multimodal applications
  • Efficient deployment
  • Local and cloud environments

Google states that Gemma 4 is released under Apache 2.0 and is designed for deployment across environments ranging from personal computers to cloud infrastructure. 

The Gemma ecosystem also supports CPU, GPU, and TPU deployment, making it attractive for teams with different hardware environments. 

Enterprise verdict

Gemma is particularly interesting when model efficiency, broad hardware support, and multimodal or agentic workloads matter.

DeepSeek Reasoning + technical workloads Strong Excellent Excellent Excellent
GLM Agentic engineering Strong Excellent Excellent Excellent
Llama Ecosystem + vendor support Excellent Strong Strong Strong
Mistral Open + managed enterprise options Excellent Excellent Strong Strong
Gemma Efficiency + multimodal Excellent Strong Strong Strong

These are starting assessments, not final rankings.

The best enterprise model depends on the workload, infrastructure, license, and business requirements.

What Enterprises Should Compare Before Choosing a Model

A strong enterprise evaluation should go beyond benchmark scores.

Model Capability

Measure:

  • Accuracy

  • Developer overhead

Enterprise Integration

Evaluate compatibility with:

  • RAG
  • Existing APIs
  • AI gateways
  • Kubernetes
  • AWS
  • Identity systems
  • Monitoring
  • LLMOps

Best Open-Source LLM for Enterprise RAG

Enterprise RAG combines an LLM with a retrieval system that provides relevant company information before generation.

Typical sources include:

  • Internal documentation
  • Policies
  • Product information
  • Support tickets
  • Technical documentation
  • Contracts
  • Knowledge bases

The model needs to understand retrieved context and produce an answer that stays grounded in the provided information.

Qwen for Enterprise RAG

Qwen is a strong general-purpose option because of its broad language support, context capabilities, and large model ecosystem.

It is particularly attractive for:

  • Multilingual knowledge bases
  • Internal enterprise assistants
  • Technical documentation
  • Large document collections

DeepSeek for Enterprise RAG

DeepSeek is especially interesting when retrieved information requires substantial reasoning.

Examples include:

  • Technical research
  • Financial analysis
  • Complex document comparison
  • Engineering knowledge systems

GLM for Enterprise RAG

GLM is a good candidate for RAG systems that also need multi-step reasoning or agentic actions after retrieving information.

RAG recommendation

For a new enterprise RAG project, start with:

Qwen + DeepSeek + GLM

Then benchmark:

  • Retrieval accuracy
  • Grounded answer quality
  • Citation correctness
  • Long-context performance
  • Latency
  • Cost

Best Open-Source LLM for Enterprise Coding

Software teams have become one of the largest enterprise users of LLMs.

Typical workloads include:

  • Code generation
  • Code review
  • Debugging
  • Refactoring
  • Test creation
  • Repository analysis
  • Coding agents

Qwen

Qwen3-Coder is one of the strongest choices for this category because it is specifically designed around software engineering and agentic coding.

DeepSeek

DeepSeek remains a strong choice when coding tasks require substantial reasoning.

GLM

GLM is especially relevant when coding becomes a long-running agent task involving terminal use, tool calling, testing, and repeated iterations.

Coding recommendation

For enterprise developer platforms, the initial benchmark should include:

Qwen3-Coder + DeepSeek + GLM

Measure developer acceptance, task completion, retry rate, latency, and cost per successful task.

Best Open-Source LLM for AI Agents

Enterprise agents can perform actions instead of simply returning text.

Examples include:

  • Creating support tickets
  • Updating CRM records
  • Querying databases
  • Running internal tools
  • Searching knowledge systems
  • Writing code
  • Executing operational tasks

For agents, model quality is only one part of the system.

Evaluate:

  • Tool selection
  • Tool argument accuracy
  • Multi-step planning
  • Error recovery
  • Structured output
  • Context management
  • Task completion rate

Qwen

Qwen has a particularly strong agent ecosystem, including dedicated coding models and agent tooling.

DeepSeek

DeepSeek is a strong candidate when the agent requires substantial reasoning before taking an action.

GLM

GLM is particularly relevant for longer-running engineering and operational agents.

Other Models

MiniMax and newer Kimi models should also be considered when their current capabilities match the specific agent workload.

Agent recommendation

Don't choose the model from a benchmark score alone.

Measure:

successful workflows / total workflows

and then calculate the cost per successful workflow.

Best Open-Source LLM for Enterprise Customer Support

Customer support has different requirements.

I support dashboard with conversation history, knowledge retrieval, metrics (96% accuracy, 120ms latency), Qwen, Llama, Mistral, Gemma.

The model needs to:

  • Follow business policies
  • Understand customer history
  • Retrieve knowledge
  • Maintain tone
  • Avoid unsupported claims
  • Produce structured responses
  • Escalate when necessary

For this workload, an expensive reasoning model may not always be necessary.

A smaller, faster model with strong RAG can provide better economics.

Qwen

Strong candidate for multilingual customer support.

Llama

Strong candidate when the enterprise already has a mature Llama-based ecosystem.

Mistral

Strong option for enterprise deployments that prioritize private infrastructure and managed cloud choices.

Gemma

Useful when efficiency and smaller deployment footprints matter.

Recommendation

For support systems, prioritize:

  • Answer accuracy
  • Grounding
  • Latency
  • Cost per conversation
  • Escalation accuracy

rather than maximum benchmark reasoning.

Best Open-Source LLM for Document Intelligence

Document workloads can include:

  • Contracts
  • Invoices
  • Reports
  • Legal documents
  • Technical manuals
  • Financial statements
  • Internal policies

The model must often combine:

document understanding + extraction + reasoning + structured output

Qwen, Gemma, Mistral, DeepSeek, and GLM can all be considered depending on the document type and modality.

For multimodal documents, evaluate models that can directly handle the relevant images, layouts, tables, or scanned pages instead of relying only on text extraction.

Best Open-Source LLM for Multilingual Enterprise AI

For international businesses, multilingual support can be more important than raw English benchmark performance.

Qwen has particularly broad language coverage across its newer model generations.

It is therefore a strong first choice for:

  • Global customer support
  • International search
  • Translation
  • Multilingual knowledge assistants
  • Cross-language document workflows

Kimi and other Chinese model families can also be evaluated when their current language support matches the business requirements.

The correct benchmark should use the actual languages your customers speak.

Best Open-Source LLM for Long Documents

Long-context models are attractive for:

  • Legal analysis
  • Technical documentation
  • Large repositories
  • Research
  • Enterprise knowledge bases

But enterprises should avoid using maximum context as a substitute for good retrieval.

A strong architecture combines:

  • Document indexing
  • Retrieval
  • Reranking
  • Context construction
  • LLM generation

The model should receive the information that matters rather than every document available in the enterprise.

API vs Private Deployment

One of the biggest enterprise decisions is whether to use a hosted API or deploy the model privately.

Hosted API

A managed API is usually preferable when:

  • The product is still being validated
  • Traffic is unpredictable
  • The company wants minimal infrastructure work
  • The latest models are required quickly

Private Deployment

Private inference is more attractive when:

  • Data is sensitive
  • Source code is proprietary
  • Data residency matters
  • Usage is large and predictable
  • The company needs more control
  • Custom inference is required

Neither approach is automatically cheaper.

Calculate the total cost for the expected workload.

Private LLM Deployment

Private deployment can run on:

  • Dedicated servers
  • Cloud GPU instances
  • Kubernetes
  • Amazon EKS
  • Private data centers

Common inference engines include:

  • vLLM
  • SGLang
  • TensorRT-LLM
  • llama.cpp
  • Ollama for smaller local environments

For enterprise workloads, vLLM or SGLang are often stronger choices for high-throughput serving.

Enterprise LLM on AWS

AWS provides several options for private model serving.

A simplified architecture can use:

Component Purpose
Amazon EC2 GPU Model inference
Amazon EKS Kubernetes platform
Amazon S3 Model artifacts
Amazon VPC Network isolation
IAM Identity and permissions
Secrets Manager Credential management
CloudWatch Monitoring
ECR Container images
KMS Encryption

The appropriate GPU depends on model size and workload.

Smaller enterprise models may fit on lower-memory GPUs, while large Qwen, DeepSeek, or GLM deployments can require H100, H200, or newer Blackwell-class systems.

Kubernetes for Enterprise LLMs

Kubernetes is particularly useful when organizations operate more than one model or application.

It provides:

  • GPU scheduling
  • Service discovery
  • Scaling
  • Deployment management
  • Isolation
  • Rollouts
  • Monitoring integration

Amazon EKS can provide this functionality inside an AWS environment.

Enterprise Model Routing

Large organizations don't always need one model.

A model-router architecture can select a model based on:

  • Task type
  • Complexity
  • Context size
  • Latency target
  • Cost target
  • Availability

For example, a simple classification request may use a smaller model while a complex coding or research request uses a larger reasoning model.

This approach can reduce average infrastructure and API costs.

Enterprise LLM Security

The following security requirements should be addressed before production.

Important areas include:

  • Identity
  • Authentication
  • Authorization
  • Encryption
  • Network isolation
  • Secret management
  • Audit logs
  • Data retention
  • Model access
  • Prompt logging policies

For sensitive workloads, keep inference infrastructure private and restrict access through authenticated internal services.

Enterprise LLM Licensing

License evaluation should happen before implementation rather than after the product is built.

Review:

  • Exact model
  • Exact version
  • Model-weight license
  • Code license
  • Commercial-use rights
  • Fine-tuning rights
  • Redistribution
  • Derivative-model rules
  • Acceptable-use requirements

This is especially important because two versions from the same model family can have different licensing terms.

Enterprise LLM Cost

The most useful financial metric is not always token price.

For self-hosted AI, consider:

  • GPU compute
  • Storage
  • Networking
  • Kubernetes
  • Monitoring
  • Engineering
  • Model upgrades

Then calculate:

Cost per successful task

For an agent:

Cost per successful workflow

For RAG:

Cost per successful grounded response

For coding:

Cost per accepted software-engineering task

This makes different model architectures easier to compare financially.

Total Cost of Ownership

A useful enterprise TCO calculation includes:

Cost Category Examples
Model API or GPU
Infrastructure EC2, EKS, storage
Networking Traffic and private connectivity
Operations DevOps and LLMOps
Monitoring Metrics and logs
Engineering Model integration
Maintenance Upgrades and testing

The cheapest model is not automatically the cheapest platform.

A model that requires significantly more retries, larger GPUs, or more human review can have a higher real-world cost.

Best Open-Source LLM by Enterprise Workload

Enterprise Workload Best Starting Candidates
General enterprise AI Qwen
Enterprise RAG Qwen / DeepSeek
Enterprise coding Qwen3‑Coder / DeepSeek
Coding agents Qwen / GLM
Reasoning‑heavy workloads DeepSeek
Agentic engineering GLM
Multilingual AI Qwen
Customer support Qwen / Llama / Mistral
Document intelligence Qwen / Mistral / Gemma
Private deployment Qwen / Llama / Mistral
Large enterprise platform Qwen / DeepSeek / GLM

These are starting candidates, not permanent rankings.

When Should an Enterprise Use a Smaller Model?

A common mistake is assuming the biggest model will always provide the best ROI.

Smaller models can be preferable when:

  • Tasks are repetitive
  • Context requirements are moderate
  • Latency matters
  • GPU budgets are limited
  • High concurrency is required

A smaller model may also be easier to run across multiple replicas.

For many enterprise applications, quality per dollar matters more than maximum model size.

How Should an Enterprise Choose an Open-Source LLM?

There is no single model that is best for every business.

The right choice depends on five practical questions:

  1. What will the model actually do?
  2. How sensitive is the data?
  3. How much traffic will it handle?
  4. What infrastructure can the company operate?
  5. What is the acceptable cost per successful task?

A useful enterprise evaluation should therefore start with the workload rather than the model brand.

Best Model for Large Enterprises

For large organizations, the strongest starting shortlist is:

  • Qwen
  • DeepSeek
  • GLM
  • Llama
  • Mistral

These ecosystems cover most major enterprise requirements.

Qwen

Best when the company wants a broad ecosystem covering coding, reasoning, agents, multilingual workloads, and private deployment.

DeepSeek

Best when technical reasoning, coding, and complex analysis are major requirements.

GLM

Best when advanced agentic workflows and long-running engineering tasks are important.

Llama

Best when ecosystem maturity, broad vendor support, and existing enterprise integrations are priorities.

Mistral

Best when organizations want a strong combination of open-weight models and managed enterprise deployment options.

Best Model for Startups

Startups should usually avoid starting with the largest model they can find.

Their priorities are normally:

  • Fast development
  • Low initial cost
  • Simple APIs
  • Easy scaling
  • Limited operational overhead

A practical starting shortlist is:

  • Qwen
  • DeepSeek
  • Mistral

Then add GLM or another specialized model when the workload requires it.

For a startup, hosted inference is often the fastest route to product validation.

Self-hosting becomes more interesting once usage becomes predictable or privacy requirements become stronger.

Best Model for Regulated or Sensitive Data

When data is sensitive, technical capability is only one part of the decision.

Consider:

  • Private deployment
  • Data residency
  • Network isolation
  • Encryption
  • Access control
  • Audit logs
  • Retention policies
  • Model licensing

For these workloads, a model that can be deployed inside a private AWS or Kubernetes environment may be more attractive than a model that is slightly better on a benchmark but requires external API access.

Qwen, Llama, Mistral, DeepSeek, and GLM can all be evaluated for private deployment depending on the exact model and license.

Best Model for Enterprise RAG

For RAG, the model itself is only one part of the architecture.

A strong RAG system also needs:

  • Good document ingestion
  • Effective chunking
  • Strong embeddings
  • Retrieval
  • Reranking
  • Context construction
  • Grounded generation

For the model layer, a strong shortlist is:

Qwen for broad multilingual and enterprise workloads

DeepSeek for reasoning-heavy documents

GLM for agent-assisted knowledge workflows

Mistral for enterprise deployments where its ecosystem and infrastructure options are a good fit

Llama where an existing Llama-based stack already exists

Best Model for Enterprise Coding

For software engineering teams, I'd start with:

  • Qwen3-Coder
  • DeepSeek
  • GLM

Use the same repository and same tasks for every model.

Measure:

  • Code correctness
  • Debugging
  • Refactoring
  • Repository changes
  • Tests
  • Tool usage
  • Review acceptance
  • Cost per completed task

The model with the highest benchmark score is not necessarily the model that gives developers the greatest productivity increase.

Best Model for Enterprise AI Agents

For agents, prioritize:

  • Tool calling
  • Planning
  • Structured output
  • Error recovery
  • Long context
  • Task completion
  • Reliability

A strong enterprise agent benchmark should use real business tasks rather than generic prompts.

For example:

  • Create a support ticket
  • Search internal documentation
  • Update a CRM record
  • Analyze a customer account
  • Produce a financial summary
  • Open a software issue
  • Generate and test a code change

Measure the entire task, not just the first model response.

Best Model for Multilingual Enterprise AI

Global organizations should test their actual languages.

Do not assume a model's multilingual rating represents the quality your company needs.

Test:

  • Customer support
  • Search
  • Translation
  • Document understanding
  • Internal communication
  • Mixed-language conversations

Qwen is particularly attractive for businesses with broad multilingual requirements, but the final decision should still be based on the languages and domain-specific content your employees or customers actually use.

Best Model for Private Deployment

For private deployment, the model should work well with your selected infrastructure.

Common deployment choices include:

  • Ollama for development
  • vLLM for production inference
  • SGLang for supported high-performance workloads
  • Docker
  • Kubernetes
  • Amazon EKS

Qwen is particularly flexible in this area because of its broad model range and extensive deployment ecosystem.

Llama and Mistral also have mature private-deployment ecosystems.

DeepSeek and GLM can be attractive when their capabilities justify the required GPU infrastructure.

Best Model for AWS

AWS deployment introduces an additional decision:

Which model gives the best quality relative to GPU cost?

A simple private architecture may use:

  • Amazon EC2 GPU
  • vLLM
  • Amazon S3
  • Amazon VPC
  • IAM
  • Secrets Manager
  • CloudWatch

A larger platform may use:

  • Amazon EKS
  • GPU node pools
  • Karpenter
  • vLLM or SGLang
  • AI gateway
  • Model routing
  • Central observability

Your AWS model choice should therefore consider:

  • GPU memory
  • Model size
  • Quantization
  • Context
  • Concurrent users
  • Target latency
  • Throughput

Open Model vs Managed API

This is one of the most important enterprise decisions.

AI support dashboard with conversation history, knowledge retrieval, metrics (96% accuracy, 120ms latency), Qwen, Llama, Mistral, Gemma.

Choose a managed API when:

  • The application is still being validated
  • Usage is unpredictable
  • The team is small
  • Infrastructure isn't the core business
  • Fast deployment matters most

Choose private inference when:

  • Data sensitivity is high
  • Traffic is large and predictable
  • Custom inference is required
  • The organization needs infrastructure control
  • Long-term operating economics justify the investment

Many businesses should use both.

For example, APIs can be used for experimentation while private inference is introduced for high-volume or sensitive workloads.

Enterprise Licensing Checklist

Before approving a model, record:

Item What to Check
Exact model Name and version
Weight license Rights and restrictions
Code license Separate from weights where applicable
Commercial use Allowed or restricted
Fine‑tuning Allowed or restricted
Redistribution Terms and obligations
Derivatives Conditions
Acceptable use Restrictions
Attribution Required notices
Review date When terms were checked

This prevents a common enterprise mistake: building a product first and reviewing licensing afterward.

For more detail, read our guide about Chinese Open-Source AI Model Licenses.

Enterprise LLM Security Checklist

Before production, evaluate:

  • Identity
  • Authentication
  • Authorization
  • Encryption
  • Secrets
  • Network isolation
  • Logging
  • Monitoring
  • Data retention
  • Prompt access
  • Output handling

For internal coding assistants, consider keeping source code inside a private environment.

For customer-facing AI, ensure user information is isolated appropriately.

Enterprise LLM Cost Optimization

Model cost comes from more than tokens.

For private inference, consider:

GPU cost + storage + networking + Kubernetes + monitoring + operations

For API deployments, consider:

input tokens + output tokens + caching + retries + tool calls

For agent systems, also include:

failed attempts + additional tool calls + human review

The most useful metric is often:

Cost per successful task

This gives a much better business comparison than raw token price.

Common Enterprise Mistakes

Choosing by Benchmark Alone

A benchmark doesn't represent your business workload.

Using the Largest Model for Everything

A smaller model may provide much better economics for routine tasks.

Ignoring Licensing

The word "open" does not guarantee unrestricted commercial use.

Ignoring Retrieval

Poor RAG retrieval can make an excellent model appear weak.

Sending Too Much Context

More context can increase both cost and latency.

Ignoring Infrastructure

A model that requires a large GPU cluster may be economically unsuitable.

Using One Model for Every Task

A multi-model approach can be more efficient.

A Practical Enterprise Evaluation

Use a representative test set.

For example:

Workload Test Count
RAG 20
Coding 20
Reasoning 20
Agent tasks 20
Document processing 20

Then measure:

  • Accuracy
  • Task completion
  • Latency
  • Cost
  • Retry rate
  • Human review time

Create separate scores for:

  • Quality
  • Operations
  • Economics

Don't collapse everything into one number too early.

Enterprise Model Selection by Business Size

Company Type Starting Strategy
Small startup Hosted API + small model
Growing startup API + private pilot
Mid‑market Model benchmark + private deployment
Large enterprise Multi‑model evaluation
Highly sensitive enterprise Private inference + strong governance

The right architecture can change as the business grows.

EaseCloud Recommendation

At EaseCloud, the strongest enterprise approach is to treat model selection and infrastructure as one decision.

The process should consider:

  • Model capability
  • Security
  • Licensing
  • Infrastructure
  • Operating cost
  • Developer productivity

For organizations using Qwen, DeepSeek, GLM, or other open models, EaseCloud can support the infrastructure side through:

  • AWS AI infrastructure
  • Amazon EKS
  • Kubernetes
  • GPU architecture
  • vLLM
  • SGLang
  • Private inference
  • LLMOps
  • Observability
  • AI cost optimization

The objective is to avoid both overbuilding and underbuilding the AI platform.

For a broad enterprise deployment, start by evaluating Qwen, DeepSeek, GLM, Llama, and Mistral against your actual workload.

Is Qwen good for enterprise use?

Yes. Qwen is a strong enterprise candidate for coding, RAG, agents, multilingual workloads, and private deployment.

Is DeepSeek suitable for businesses?

Yes. DeepSeek can be particularly attractive for reasoning-heavy, technical, and coding workloads.

Is GLM suitable for enterprise AI?

Yes. GLM is particularly interesting for agentic workflows, software engineering, and complex multi-step automation.

Should enterprises self-host an LLM?

Not necessarily. Hosted APIs are often better during early experimentation, while private deployment becomes more attractive when data sensitivity, control, or predictable high usage justifies the additional infrastructure.

What is the cheapest enterprise LLM?

There is no permanent cheapest model. Calculate the total cost of your actual workload, including retries, infrastructure, and human review.

Which model is best for enterprise RAG?

Qwen, DeepSeek, GLM, Llama, and Mistral are all reasonable candidates. The retrieval system and document pipeline can have as much impact as the model itself.

Which model is best for enterprise coding?

Start with Qwen3-Coder, DeepSeek, and GLM and evaluate them using your real repositories.

Final Verdict

The enterprise LLM market has moved beyond the question:

“Which model is smartest?”

The more useful question is:

Which model provides the best combination of capability, security, deployment flexibility, and total cost for this specific business?

Model Description
Qwen The strongest all‑around starting point.
DeepSeek A strong choice for reasoning, coding, and technical workloads.
GLM A strong choice for agentic engineering and complex workflows.
Llama A mature ecosystem choice with broad enterprise adoption and tooling.
Mistral A strong option for organizations that value open models alongside managed enterprise deployment.
Gemma A useful choice where efficiency, multimodal capabilities, and flexible hardware are important.

For most enterprises, the best strategy is not to select one model immediately.

Start with a shortlist, run the same workloads, measure quality and economics, then choose the deployment architecture that matches the result.

That approach also creates the cleanest path from model evaluation to private AI infrastructure, where EaseCloud can support AWS, Kubernetes, GPU, inference, LLMOps, and cost optimization requirements.
