Core Capabilities

What we build
with LangChain

Retrieval & RAG Pipelines

RAG & Search

Retrieval-Augmented Generation with vector databases (Chroma, Pinecone, Weaviate), document loaders, text splitters, and embedding models for accurate, grounded AI responses.

Autonomous & AI Agents & Tool Calling

Agents & Tools

Autonomous agents with LangChain's agent framework — tool calling, function execution, multi-step reasoning, and ReAct patterns for complex task automation.

Production & Conversational AI

Chatbots & Assistants

Production chatbots and assistants with memory management, conversation history, streaming responses, and multi-turn dialogue powered by LangChain and LangGraph.

How It Works

From discovery to
production

AI Architecture &
Model Selection

We evaluate your use cases and design the right LangChain architecture — whether it is RAG with vector databases, autonomous agents with tool calling, or conversational AI with memory and streaming.

Agile
Development

Our enterprise solution engineers build LangChain applications iteratively — with proper chain composition, prompt management, and integration testing at every sprint.

Testing &
Evaluation

LangSmith tracing, automated evaluation datasets, and prompt regression testing. Our QA specialists and AI engineers ensure outputs are accurate, consistent, and free from hallucinations.

Deployment &
Monitoring

We deploy LangChain applications with LangServe or FastAPI, configure LangSmith monitoring, track token usage, latency, and response quality in production.

optimization

AI-driven token usage analysis, model routing between expensive and cheap models, and caching strategies to reduce LLM API costs by up to 60%.

FAQ

Frequently Asked
Questions

LangChain is a framework for building applications powered by large language models. Use it when you need RAG (answering questions from your data), AI agents (automating multi-step tasks), or any LLM application that goes beyond simple API calls.

LangChain integrates with all major providers: OpenAI (GPT-4), Anthropic (Claude), Google (Gemini), AWS Bedrock, Azure OpenAI, and open-source models through Ollama, HuggingFace, and vLLM. We help you choose the right model for your use case and budget.

Retrieval-Augmented Generation lets your AI answer questions using your own documents. We chunk your data, create vector embeddings, store them in a vector database, and retrieve relevant context at query time — ensuring accurate, grounded responses instead of hallucinations.

Yes. LangChain's agent framework enables AI systems that reason, plan, and execute actions using tools — searching databases, calling APIs, writing code, and making decisions. We build agents with ReAct patterns, tool calling, and safety guardrails.

We use LangSmith for tracing every LLM call, tracking latency, token usage, and response quality. We set up automated evaluations, alerting on quality regressions, and dashboards for cost monitoring and usage analytics.
