Implements a ReActAgent base class that orchestrates reasoning-action-observation loops by leveraging LLM native tool-calling capabilities rather than rigid prompt engineering. The framework uses a message protocol with structured content blocks to pass tool schemas directly to models (OpenAI, Anthropic, Gemini, etc.), enabling models to decide when and how to invoke tools. Tool execution is mediated through a Toolkit registry with middleware support for pre/post-processing, allowing dynamic tool composition without hardcoded function chains.
Unique: Uses model-native tool-calling APIs directly rather than parsing LLM outputs or enforcing rigid prompt templates, allowing models to leverage their native reasoning and tool-use abilities. Middleware system enables dynamic tool composition without hardcoded function chains, and message protocol with content blocks supports multimodal inputs (text, image, audio, realtime voice).
vs alternatives: Differs from LangChain's AgentExecutor by prioritizing model-driven reasoning over fixed orchestration patterns, and from AutoGen by providing lighter-weight agent abstractions with native MCP support for tool integration.
Provides a MsgHub message broker that enables inter-agent communication through a publish-subscribe architecture with support for both synchronous request-reply and asynchronous broadcast patterns. Agents register as subscribers to message topics and can broadcast messages containing structured content blocks. The system supports distributed deployment where agents run on separate processes/machines and communicate through Redis or in-memory message queues, with automatic message routing based on subscriber filters.
Unique: Implements both in-memory and Redis-backed message brokers with unified API, supporting A2A protocol for standardized agent-to-agent communication. Integrates with agent lifecycle hooks to enable automatic message handling without explicit polling, and supports multimodal message content blocks matching the core message protocol.
vs alternatives: Simpler than AutoGen's GroupChat for many use cases (no central orchestrator bottleneck), and more flexible than LangChain's tool-calling for agent coordination by providing true publish-subscribe semantics rather than request-reply only.
Enables agents to process and generate multimodal content including text, images, audio, and realtime voice streams. Agents can receive voice input via realtime APIs (OpenAI Realtime, etc.), process it with speech-to-text, reason over multimodal context, and respond with text-to-speech output. Message protocol supports content blocks for different modalities (text, image, audio), and agents can compose multimodal responses. Realtime voice integration enables low-latency voice conversations without explicit turn-taking.
Unique: Provides native support for realtime voice streams via OpenAI Realtime API and other providers, enabling low-latency voice conversations without explicit turn-taking. Message protocol supports multimodal content blocks (text, image, audio), and agents can compose multimodal responses with automatic TTS generation.
vs alternatives: More integrated than bolting on speech-to-text/TTS to text-only agents by providing native realtime voice support, and more flexible than voice-only assistants by supporting multimodal reasoning over text, images, and audio.
Enables agents to pause execution and request human input or approval at critical decision points. Agents can define interruption handlers that pause reasoning, present options to humans, and resume based on human feedback. Supports approval workflows where agents propose actions and wait for human confirmation before execution. Integrates with UserAgent for human interaction, and supports both synchronous (blocking) and asynchronous (callback-based) human input.
Unique: Provides interruption handlers that pause agent execution at critical decision points and resume based on human feedback, with support for both synchronous and asynchronous human input. Integrates with UserAgent for human interaction and supports approval workflows without custom implementation.
vs alternatives: More integrated than manual approval workflows by providing agent-level interruption primitives, and more flexible than simple blocking by supporting both synchronous and asynchronous human input patterns.
Provides lifecycle hooks (before_step, after_step, on_error, on_complete) that enable custom logic at each agent execution phase. Hooks are called automatically during agent reasoning, allowing middleware-like behavior without modifying core agent code. Supports extending AgentBase with custom agent types, custom message formatters for new LLM providers, and custom memory implementations. Extension points are designed to be composable, enabling multiple extensions to coexist without conflicts.
Unique: Provides composable lifecycle hooks (before_step, after_step, on_error, on_complete) that enable custom logic without modifying core agent code. Extension points for custom agent types, message formatters, and memory implementations enable deep customization while maintaining compatibility.
vs alternatives: More flexible than hardcoded agent implementations by providing lifecycle hooks for custom behavior, and more composable than inheritance-based extension by supporting multiple hooks without conflicts.
Provides a tuner framework for finetuning agent behaviors through reinforcement learning or supervised finetuning. Agents can be trained on task datasets to improve performance on specific domains. Supports both offline finetuning (on collected trajectories) and online finetuning (with environment interaction). Integrates with evaluation framework to measure finetuning progress and detect overfitting. Supports multiple finetuning strategies (behavior cloning, reward-based RL, etc.) with pluggable reward models.
Unique: Provides a tuner framework for finetuning agents through supervised finetuning or reinforcement learning, with support for both offline and online finetuning.

vs alternatives: More integrated than external finetuning tools by providing agent-specific finetuning primitives, and more flexible than fixed finetuning strategies by supporting multiple approaches (behavior cloning, RL, etc.).
Provides a planning system with PlanNotebook that enables agents to decompose complex tasks into subtasks and track progress. Agents can create hierarchical plans, mark subtasks as complete, and adjust plans based on execution results. PlanNotebook maintains structured task state (goals, subtasks, dependencies, status) and integrates with agent reasoning to enable plan-aware decision making. Supports dynamic replanning when execution deviates from plan.
Unique: Provides PlanNotebook abstraction that maintains structured task state (goals, subtasks, dependencies, status) and integrates with agent reasoning for plan-aware decision making. Supports dynamic replanning when execution deviates from plan, enabling adaptive task execution.
vs alternatives: More integrated than external planning tools by providing agent-level planning primitives, and more flexible than fixed task structures by supporting dynamic replanning and hierarchical task decomposition.
Abstracts multiple LLM providers (OpenAI, Anthropic, Google Gemini, Alibaba DashScope, Ollama, etc.) behind a ChatModelBase interface that handles provider-specific API differences. Supports streaming responses with token-by-token callbacks, structured output extraction via JSON schema validation, and tool-calling schema generation. Message formatters convert between AgentScope's internal message protocol and provider-specific formats (e.g., OpenAI's chat completion format vs Anthropic's native tool-use blocks), enabling seamless provider switching.
Unique: Provides unified ChatModelBase abstraction that normalizes provider differences (OpenAI vs Anthropic vs Gemini) while preserving provider-native capabilities like streaming and tool-calling. Message formatters enable bidirectional conversion between internal protocol and provider formats, allowing agents to leverage provider-specific optimizations without code changes.
vs alternatives: More comprehensive than LiteLLM for structured output and streaming, and more flexible than LangChain's LLMBase by supporting both streaming callbacks and structured output validation in the same abstraction.
