LLM agents wrap a language model with memory, planning, and tools so it can take multi-step actions autonomously — moving from answering questions to actually getting tasks done.
Key takeaways
An agent = LLM + planning loop + memory + tools; it decides which actions to take, executes them, and iterates on the results.
Types range from simple reactive agents to multi-agent systems that collaborate on complex goals.
Tool use (APIs, databases, code) is what makes agents useful — and what makes governance and security essential.
Production agents need infrastructure: a gateway for model access, guardrails, cost controls, and observability.
Turn your LLM agents into production-ready systems with TrueFoundry.
Our platform brings speed, reliability, and visibility to every stage of the agent lifecycle, from deployment and tool integration to real-time monitoring and cost optimization. With secure API routing, autoscaling, and full observability built in, TrueFoundry makes it easy to run intelligent agents at scale.
TrueFoundry's AI Gateway gives agents one governed endpoint to 1000+ models and their tools — with routing, guardrails, cost controls, and full traces, all in your own VPC.
Here's The Evaluation Framework for Proposal Template
Criteria
What should you evaluate ?
Priority
TrueFoundry
Unified API & Routing
Unified OpenAI-compatible endpoint
Is the gateway API compatible with OpenAI's
/v1/chat/completions and /v1/responses formats,
allowing consistent access across different models
through a standardized interface?
Must have
✅
Supported: OpenAI-compatible endpoint across all
providers.
Provider and model coverage
Does it support leading providers like OpenAI,
Azure OpenAI, Amazon Bedrock, Anthropic,
Gemini, Groq, plus self-hosted models?
Must have
✅
Supported: 1000+ LLMs across hosted and
self-hosted providers.
Model onboarding speed
How quickly can new models (OpenAI-compatible
and non-standard APIs) be added without code
changes?
Must have
✅
Supported: config-driven onboarding within
minutes.
Multimodal support
Does the gateway support text, vision, audio,
image generation, and embeddings through a
single interface?
Depends on use case
✅
Supported: chat, embeddings, images, audio,
rerank, and realtime APIs.
Routing, load balancing, fallback
Can requests be routed by model, provider,
latency, priority, weight, region, and failure
state with automatic retries?
Must have
✅
Supported: load balancing, fallbacks,
weighted and latency-based routing.
Model switching without code change
Is model switching supported via headers or
config without changing client code?
Must have
✅
Supported: header-based and config-based
model switching.
LangChainは、プロンプトテンプレート、ツールインターフェース、メモリ、プランナーなどのモジュール型コンポーネントを使用してエージェントを構築するためのフレームワークを提供します。例えば、エージェントは関連文書を取得し、内容を要約し、回答を統合することで、PDFのコレクションに対する複雑なクエリに答えることができます。LangChainは、ワークフローを定義し、APIを統合することで、タスク固有のエージェントとツール使用エージェントの両方を簡単に作成できるようにします。 LangChain vs LangGraph チームが多段階のエージェント実行においてグラフベースのオーケストレーションがより適している時期を判断するのに役立ちます。
Unify model and tool access, enforce guardrails and budgets, and trace every agent step from one control plane. See how TrueFoundry's AI Gateway operationalizes LLM agents.
TrueFoundry AI Gateway delivers ~3–4 ms latency, handles 350+ RPS on 1 vCPU, scales horizontally with ease, and is production-ready, while LiteLLM suffers from high latency, struggles beyond moderate RPS, lacks built-in scaling, and is best for light or prototype workloads.
