The record

Purpose: Inspect is an open-source framework for evaluating large language models across coding, agentic tasks, reasoning, knowledge, behavior, and multimodal understanding.
Reusable components: Evaluations combine datasets, solvers, and scorers, and can use more than 200 pre-built evaluations.
Evaluation results: Inspect View is a web-based tool for monitoring and visualizing evaluations.
Editor integration: The Inspect VS Code extension provides tools for browsing evaluation logs, running and debugging tasks, and configuring options.
Model integrations: Inspect has built-in support for more than 20 model providers and local inference with Hugging Face, vLLM, and SGLang.
Provider examples: Documented provider groups include OpenAI, Anthropic, Google, AWS Bedrock, Azure AI, Hugging Face, vLLM, Ollama, and SGLang.
Tools and MCP: Inspect includes standard tools for web search, code execution, text editing, computer use, and web browsing, and supports MCP tools.
Agent integrations: Inspect can integrate agents built with OpenAI Agents SDK, Pydantic AI, and LangChain, as well as CLI agents such as Claude Code, Codex CLI, and Gemini CLI.
Sandboxing: The framework supports running untrusted model code in Docker, Kubernetes, Modal, Proxmox, Vagrant, and other systems through an extension API.
Installation requirement: The getting-started instructions install Inspect from PyPI with pip install inspect-ai and say evaluation development and runs also require access to a model.
