Pre-configured template implementing retrieval-augmented generation (RAG) for question-answering over document collections. Uses LlamaIndex's document ingestion pipeline to parse files (PDF, TXT, Markdown), chunk them with configurable strategies, embed chunks via vector stores, and retrieve relevant context before passing to an LLM for answer generation. Abstracts away index construction, retrieval configuration, and prompt engineering boilerplate.
Unique: Provides end-to-end template combining LlamaIndex's document loader abstraction (supporting 100+ file types), configurable chunking strategies, and multi-backend vector store integration in a single self-contained example, reducing boilerplate compared to building RAG from raw LLM APIs
vs alternatives: More flexible and framework-agnostic than LangChain's document loaders because LlamaIndex's index abstraction decouples storage backend from retrieval logic, enabling easier swaps between vector stores without code changes
Template implementing stateful conversation over documents using LlamaIndex's chat engine, which maintains conversation history while retrieving relevant document context for each turn. Handles context window management by summarizing or filtering conversation history, retrieves fresh context from the document index per query, and passes both history and context to the LLM to generate contextually-aware responses that reference previous turns.
Unique: LlamaIndex's chat engine abstracts context window management and retrieval scheduling, automatically deciding when to retrieve fresh context vs. rely on conversation history, whereas raw LLM APIs require manual orchestration of these decisions
vs alternatives: Simpler than building conversation state management with LangChain's memory abstractions because LlamaIndex's chat engine integrates retrieval and history in a single component, reducing glue code
Template providing utilities to evaluate RAG system quality across multiple dimensions: retrieval quality (precision, recall, NDCG), answer quality (relevance, factuality, citation accuracy), and end-to-end performance. Includes evaluation datasets, metrics computation, and comparison tools to measure impact of configuration changes. Supports both automated metrics (embedding-based similarity) and human evaluation workflows.
Unique: LlamaIndex's evaluation framework integrates retrieval and generation metrics in a single pipeline, enabling end-to-end quality assessment, whereas most RAG systems require separate evaluation tools for retrieval and generation
vs alternatives: More comprehensive than generic NLG evaluation because LlamaIndex's metrics include retrieval-specific measures (precision, recall) alongside generation metrics, providing holistic RAG quality assessment
Template providing utilities to monitor and optimize LLM API costs and latency in RAG pipelines. Tracks token usage per component (retrieval, synthesis, tool calls), identifies bottlenecks, and suggests optimizations (smaller models, caching, batching). Implements caching strategies (semantic caching, exact-match caching) to reduce redundant LLM calls, and provides cost estimation before execution.
Unique: LlamaIndex's cost tracking is integrated into the query engine, enabling automatic token counting and cost attribution per component, whereas most RAG systems require manual instrumentation
vs alternatives: More granular than LLM provider dashboards because LlamaIndex tracks costs at the component level (retrieval vs. synthesis), enabling targeted optimization
Template using LlamaIndex's structured output capabilities (via Pydantic schema definitions) to extract typed data from documents. Defines a Pydantic model representing desired output structure (e.g., invoice fields, entity lists), passes documents through LlamaIndex's extraction pipeline which uses the LLM to parse content and map it to the schema, and returns validated structured objects. Handles schema validation, type coercion, and optional field handling automatically.
Unique: Uses Pydantic schema as a declarative interface for extraction, enabling type-safe output and automatic validation, whereas most extraction templates rely on regex or rule-based parsing that lacks type guarantees
vs alternatives: More maintainable than prompt-based extraction because schema changes are code changes (caught by type checkers) rather than prompt tweaks, and Pydantic validation catches malformed extractions before they reach downstream systems
Template implementing an agentic loop where an LLM reasons over multiple documents and tools to answer complex queries. Uses LlamaIndex's agent framework to define tools (document search, calculation, external API calls), implements a ReAct-style loop where the agent plans actions, executes tools, observes results, and refines its approach. Manages context across multiple document indexes and tool invocations, handling tool selection, parameter binding, and result integration into the reasoning loop.
Unique: LlamaIndex's agent framework integrates document retrieval as a first-class tool alongside custom tools, enabling seamless reasoning over documents and external systems in a unified loop, whereas LangChain agents require explicit tool definitions for document access
vs alternatives: More document-aware than generic agent frameworks because LlamaIndex's agent tools are optimized for index queries and can leverage semantic search, whereas generic agent frameworks treat documents as opaque external tools
Template exposing LlamaIndex's chunking and indexing configuration options (chunk size, overlap, separator strategy, node post-processors) as configurable parameters. Allows developers to experiment with different chunking strategies (fixed-size, semantic, hierarchical) and index types (vector, keyword, tree-based) without code changes. Includes utilities to evaluate chunking quality and measure retrieval performance across configurations.
Unique: Exposes LlamaIndex's low-level chunking and node post-processor APIs as configuration templates, enabling experimentation without modifying core indexing code, whereas most RAG templates hard-code chunking parameters
vs alternatives: More flexible than LangChain's text splitters because LlamaIndex's node abstraction allows post-processing (metadata enrichment, filtering) after chunking, enabling more sophisticated indexing strategies
Template supporting indexing of multi-modal documents (PDFs with images, scanned documents, mixed text/image content) using LlamaIndex's image extraction and OCR capabilities. Automatically extracts images from documents, generates descriptions or embeddings for images, indexes both text and image content separately, and enables retrieval that matches queries against both text and visual content. Handles image-to-text mapping to preserve document structure.
Unique: Integrates image extraction, OCR, and multi-modal embedding in a single indexing pipeline, whereas most RAG templates treat images as opaque binary data or require manual extraction
vs alternatives: More comprehensive than LangChain's document loaders because LlamaIndex's image node abstraction preserves image-to-text relationships and enables cross-modal retrieval, whereas LangChain typically extracts images separately

AutoGen 0.4 implements a strict three-layer architecture (autogen-core, autogen-agentchat, autogen-ext) where agents communicate via an event-driven runtime using typed message protocols. The AgentRuntime abstraction supports both SingleThreadedAgentRuntime for local execution and GrpcWorkerAgentRuntime for distributed multi-process coordination, with subscription-based message routing that decouples agent communication from implementation details. Messages are strongly typed via Pydantic models (LLMMessage, BaseChatMessage, BaseAgentEvent), enabling compile-time validation and IDE support.
Unique: Implements a protocol-based agent abstraction (Agent interface) that decouples agent implementation from runtime, enabling the same agent code to run in SingleThreadedAgentRuntime, GrpcWorkerAgentRuntime, or custom runtimes without modification. This is achieved through Pydantic-validated message types and subscription-based routing rather than direct method calls, making the system fundamentally composable.
vs alternatives: Unlike LangGraph's state machine approach or CrewAI's sequential task execution, AutoGen's event-driven architecture enables true asynchronous agent coordination with compile-time type safety and seamless distributed execution via gRPC without code changes.
The autogen-agentchat package provides high-level agent abstractions including AssistantAgent (LLM-powered reasoning), CodeExecutorAgent (sandboxed code execution), and specialized agents (WebSurferAgent, FileSurferAgent) that implement common multi-agent patterns. Each agent encapsulates a specific capability (LLM inference, code execution, web interaction) and integrates with the underlying AgentRuntime via the Agent protocol, allowing developers to compose agents into teams without managing low-level message routing.
Unique: Provides a unified Agent interface where AssistantAgent, CodeExecutorAgent, WebSurferAgent, and FileSurferAgent all implement the same protocol, enabling them to be composed into teams without adapter code. Each agent type encapsulates domain-specific logic (LLM calls, subprocess execution, web scraping) while exposing a consistent message-based interface, allowing developers to swap implementations or add custom agents.
AutoGen scores higher at 77/100 vs LlamaIndex Starter at 59/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
vs alternatives: More composable than LangGraph's node-based approach because agents are first-class runtime objects with consistent interfaces; more flexible than CrewAI's role-based agents because agents can be dynamically instantiated and reconfigured at runtime without role definitions.
AutoGen Studio provides a web-based UI for building multi-agent systems without writing code. Users define agents, configure LLM providers, design group chat workflows, and test conversations through a visual interface. The system generates AutoGen Python code that can be exported and deployed. Studio integrates with the autogen-agentchat API and provides real-time conversation testing, agent configuration management, and workflow visualization.
Unique: Provides a visual interface that generates valid AutoGen code, bridging the gap between no-code design and code-based customization. Users can design workflows visually and export runnable Python code that uses the same autogen-agentchat API, enabling gradual transition from no-code to code-based development.
vs alternatives: More integrated than separate no-code tools because generated code is directly executable AutoGen code; more flexible than pure no-code platforms because users can export and customize generated code.
AutoGen supports both Python and .NET (C#) ecosystems with cross-language interoperability through gRPC. The .NET SDK provides equivalent abstractions (Agent, AgentRuntime, ChatCompletionClient) that communicate with Python agents via gRPC workers. This enables mixed-language agent teams where Python agents and .NET agents operate in the same system, with transparent message passing and shared runtime infrastructure.
Unique: Implements cross-language support through GrpcWorkerAgentRuntime that treats .NET agents as remote workers communicating via gRPC, enabling the same Agent protocol to work across language boundaries. This is achieved through protocol buffer definitions that define message schemas language-agnostically.
vs alternatives: More integrated than separate Python and .NET frameworks because agents are truly interoperable; more flexible than language-specific frameworks because teams can choose the best language for each agent.
AutoGen's memory system manages agent context and conversation history through configurable storage backends (in-memory, file-based, database). The system supports context windowing strategies (sliding window, summarization) to manage token usage in long conversations. Memory is integrated with the Agent protocol, allowing agents to access conversation history and maintain state across multiple interactions. The system supports both short-term memory (current conversation) and long-term memory (persistent storage).
Unique: Implements memory as a pluggable component with multiple storage backends, enabling agents to work with different memory strategies without code changes. Context windowing is configurable and can use different strategies (sliding window, summarization, semantic pruning) depending on application needs.
vs alternatives: More flexible than LangGraph's built-in memory because it supports multiple backends and strategies; more comprehensive than CrewAI's memory because it includes both short-term and long-term storage with configurable windowing.
AutoGen integrates with OpenTelemetry to provide comprehensive observability of agent execution, including traces of agent interactions, LLM calls, tool invocations, and message routing. The system exports traces to OpenTelemetry-compatible backends (Jaeger, Datadog, etc.) for visualization and analysis. Telemetry is built into the core runtime, requiring no agent code changes to enable tracing.
Unique: Integrates OpenTelemetry at the core runtime level, enabling automatic tracing of all agent interactions without requiring agent code changes. Traces capture the full execution graph including message routing, LLM calls, and tool invocations, providing comprehensive visibility into agent behavior.
vs alternatives: More comprehensive than LangGraph's logging because it captures the full execution graph; more standardized than custom logging because it uses OpenTelemetry, enabling integration with any observability platform.
AutoGen's BaseGroupChat abstraction enables multi-agent conversations where agents take turns or participate based on routing logic, with pluggable termination conditions (MaxMessageTermination, TextMentionTermination, custom predicates) that determine when a conversation ends. The group chat maintains conversation history, manages agent selection for each turn, and integrates with the AgentRuntime to coordinate message passing between agents. Termination conditions are evaluated after each agent response, enabling early exit when goals are met or token limits approached.
Unique: Implements termination conditions as composable predicates (MaxMessageTermination, TextMentionTermination, custom functions) that are evaluated after each agent turn, decoupling conversation flow control from agent logic. This enables developers to mix-and-match termination strategies without modifying agent code, and to add new conditions by implementing a simple interface.
vs alternatives: More flexible than CrewAI's task-based termination because conditions are evaluated dynamically per turn; more explicit than LangGraph's conditional edges because termination is a first-class concept with dedicated abstractions rather than embedded in routing logic.
AutoGen's code execution system (via CodeExecutorAgent and autogen-ext) supports multiple execution backends including local subprocess execution, Docker containers, and Jupyter notebooks, all exposed through a unified CodeExecutor interface. Code is executed in isolated environments with configurable timeouts, resource limits, and output capture. The system integrates with the agent runtime to return execution results as typed messages, enabling agents to reason about code output and iterate on implementations.
Unique: Abstracts code execution through a CodeExecutor protocol with multiple implementations (LocalCommandLineCodeExecutor, DockerCommandLineCodeExecutor, JupyterCodeExecutor), allowing the same agent code to run against different backends by swapping the executor instance. This is achieved through dependency injection at agent initialization, enabling seamless environment switching.
vs alternatives: More flexible than LangGraph's built-in code execution because it supports multiple backends and isolation levels; more secure than CrewAI's subprocess execution because it provides Docker containerization as a first-class option with explicit timeout and resource management.
