Big-AGI: The Expert's AI Workspace

# Big-AGI > Big-AGI is a browser-based AI workspace for people who work with more than one model. Bring your own API keys for 30+ providers (OpenAI, Anthropic, Google Gemini, SpaceXAI, Mistral, DeepSeek, NVIDIA's free hosted catalog of open models, and more), run several models on the same prompt, and merge the answers with Beam. Keys stay on your device and chats are local-first, with optional sync. No markup and no intermediary on model pricing, no vendor lock-in. Built by Enrico Ros, the founder of Token Fabrics LLC; the core with full models support is open source under the MIT license. ## Product - [Homepage](https://big-agi.com/): The AI workspace for experts. Multi-model reasoning, personas with memory, advanced model controls wrapped in a fresh UX. BYO API keys, zero lock-in. - [Launch the app](https://app.big-agi.com/): Free web app, no signup required to start. - [Models](https://big-agi.com/models): One sortable table of price, context window, and capabilities for every model Big-AGI indexes (692 models across 22 vendor pages), refreshed every 30 minutes. Also connects to any OpenAI-compatible endpoint, every model on OpenRouter, and local runtimes like LocalAI, Ollama, and LM Studio. - [Beam](https://big-agi.com/beam): Runs the same prompt across 2 to 24 models in parallel, then merges the answers into one response instead of leaving you to compare them by hand. - [Model Controls](https://big-agi.com/controls): Per-model parameters most consumer apps hide: reasoning effort, thinking budgets, verbosity, web and tool controls, temperature. - [Changelog](https://big-agi.com/changes): Shipping log of new models, features, and fixes, updated weekly. ## Providers (22 live vendor pages: pricing, model lists, and capabilities per provider) - [OpenAI](https://big-agi.com/openai): Use OpenAI in Big-AGI with your own API key: provider rates, no markup, no intermediary. Run it next to other models and merge the answers with Beam. - [Anthropic](https://big-agi.com
