# 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 (700 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.

What each includes, who bills you, and whether to keep the subscription you already pay. - [Start Here: Your first chat](https://big-agi.com/docs/first-chat.md): Launch the app, connect a model vendor, and chat - with a tour of the screen and the backup habit to start on day one. - [Connect Models: Connect Models](https://big-agi.com/docs/connect-models.md): Connecting an AI service is what puts models in Big-AGI: where to start, one key for many models, every service in the app, the model each job uses, and models on your own machines. - [Connect Models: Get an API key: Alibaba Cloud](https://big-agi.com/docs/connect-alibaba.md): An Alibaba Cloud key authenticates only against the endpoint of the region that issued it, and Big-AGI dials the international one by default. - [Connect Models: Get an API key: Anthropic](https://big-agi.com/docs/connect-anthropic.md): Create a key in the Claude Console, top up the balance, and turn on Direct Connection once the key is in the browser. - [Connect Models: Connect an Azure OpenAI resource](https://big-agi.com/docs/connect-azure.md): Azure asks for two fields rather than one - a resource endpoint and a key - and lists nothing until you have deployed a model yourself. - [Connect Models: Connect AWS Bedrock with an AWS credential](https://big-agi.com/docs/connect-bedrock.md): Bedrock takes an AWS credential and a region rather than an API key, and only a long-term key can list models at all. - [Connect Models: Get a Cerebras key, and leave Direct Connection on](https://big-agi.com/docs/connect-cerebras.md): Cerebras is the one AI service that ships with Direct Connection already on, because the browser path works where the server path meets a bot challenge. - [Connect Models: Get an API key: Cohere](https://big-agi.com/docs/connect-cohere.md): Big-AGI reaches Cohere through its OpenAI-compatibility endpoint, so the model list you get is whatever that endpoint exposes. - [Connect Models: Get an API key: Deepseek](https://big-agi.com/docs/connect-deepseek.md): Deepseek bills only against money already deposited, so the balance is the whole limit - create the key, top up, paste it into Big-AGI. - [Connect Models: Get a Gemini key: FREE or paid](https://big-agi.com/docs/connect-gemini.md): AI Studio issues a Gemini key on the FREE tier with no billing account, and Direct Connection moves that key from a header into the request URL. - [Connect Models: Get a Groq key with no payment method](https://big-agi.com/docs/connect-groq.md): Groq's free plan has no bill to cap - the limit is a rate limit, so this account runs out of speed long before it runs out of money. - [Connect Models: Connect LM Studio](https://big-agi.com/docs/connect-lmstudio.md): LM Studio serves only the model you have loaded, not every model you downloaded - so load one, start the server, enable CORS, and give Big-AGI the address. - [Connect Models: Connect LocalAI](https://big-agi.com/docs/connect-localai.md): Big-AGI ships a capability list for LocalAI, naming what this runtime covers and what it does not - plus the address, and an optional key. - [Connect Models: Get an API key: Mistral](https://big-agi.com/docs/connect-mistral.md): Mistral gates on activation rather than on a deposit: activate the account - free mode counts - then create the key and paste it into Big-AGI. - [Connect Models: Get a Moonshot key from one of two consoles](https://big-agi.com/docs/connect-moonshot-ai.md): One field accepts two kinds of Moonshot key, detected from the string itself - and the kind you paste decides the endpoint, the models and the browser path. - [Connect Models: Connect NVIDIA NIM, hosted or your own](https://big-agi.com/docs/connect-nvidia-nim.md): This is the only cloud member where an address alone is a valid credential: an nvapi- key for the hosted endpoint, or a host for a server you run. - [Connect Models: Connect Ollama](https://big-agi.com/docs/connect-ollama.md): Ollama takes no key at all - only an address - so the whole failure surface here is whether your browser is allowed to talk to the runtime. - [Connect Models: Get an API key: OpenAI](https://big-agi.com/docs/connect-openai.md): An OpenAI key belongs to a project inside an organisation, and that choice is made at creation - it decides the model set and the budget. - [Connect Models: Link an OpenRouter key from inside Big-AGI](https://big-agi.com/docs/connect-openrouter.md): A button in the setup panel installs the OpenRouter key without copy-paste, and one account then reaches many AI services on one balance. - [Connect Models: Get an API key: Perplexity](https://big-agi.com/docs/connect-perplexity.md): The Perplexity API is its own product with its own account object - an API group - and its own credit balance, which blocks the keys at zero. - [Connect Models: Get an API key: Sakana AI](https://big-agi.com/docs/connect-sakana.md): Sakana AI spreads one key across a pool of AI services, for users outside the European Economic Area, the UK and Switzerland, on credit that expires in six months. - [Connect Models: Get an API key: Together AI](https://big-agi.com/docs/connect-together.md): The cure for Together AI calls rejected for speed is a switch inside Big-AGI - Rate Limiter - which spaces Big-AGI's own requests about a second apart. - [Connect Models: Get an API key: xAI](https://big-agi.com/docs/connect-xai.md): An xAI key comes from the developer console, which bills separately from any consumer subscription and holds the account's monthly cap. - [Connect Models: Get an API key: Z.ai](https://big-agi.com/docs/connect-zai.md): Z.ai has no server-side environment variable in Big-AGI, so this key always lives in your browser - one endpoint, one balance, one limit. - [Connect Models: Connect any OpenAI-compatible endpoint](https://big-agi.com/docs/connect-custom-endpoints.md): Point Big-AGI at vLLM, llama.cpp, LiteLLM, a proxy or a company gateway: models are scanned and join the list automatically. - [Features: The AI Inspector](https://big-agi.com/docs/feature-ai-inspector.md): The AI Inspector captures the literal JSON request that left your browser: how to open it, what each frame proves, which requests carry a body, and what it leaves out. - [Features: Get material in, take deliverables out](https://big-agi.com/docs/feature-attachments.md): Every way material gets into a conversation - files, PDFs, screenshots, web pages, Drive - and every way an answer leaves it: diagrams, charts, runnable pages, images. - [Features: Run several models at once](https://big-agi.com/docs/multi-model.md): One question to several models at once, answers side by side: why it turns uncertainty into confidence, how a Beam run works, and what it costs. - [Features: Combining answers](https://big-agi.com/docs/multi-model-fusion.md): Fuse, Guided, Compare and Custom over the same answers: what each one sends, what it returns, how many calls it costs, and how to write your own. - [Features: When the models disagree](https://big-agi.com/docs/multi-model-read-disagreement.md): Disagreement marks the assumption your question rests on. How to read a split, and when to overrule the merged answer. - [Features: What Direct Connection does](https://big-agi.com/docs/feature-direct-connection.md): Direct Connection sends requests from your browser straight to the AI service - our servers never see your request, your data, or your key. What it needs, and where the toggle is. - [Features: What a persona is](https://big-agi.com/docs/feature-personas.md): A persona is a saved role: instruction, reference material, a pinned model, a voice, and more. Why to build them, what one holds, and how they carry into chats and Beams. - [Features: An hour of speech, transcribed whole](https://big-agi.com/docs/feature-ramble.md): Long-form dictation: record up to an hour and transcribe your speech with the highest quality. Record on your mobile device, use the transcript immediately on desktop. - [Features: What syncs between devices](https://big-agi.com/docs/feature-sync.md): What syncs and what stays on the device you typed it on, plus phone use, offline behaviour, conflicts, and why sync is not a backup. - [Features: Talk to it instead of typing](https://big-agi.com/docs/feature-voice.md): Turn on the microphone, dictate into the composer, hold a spoken conversation, pick a voice, and know what happens to the audio. - [Guides: Model Settings](https://big-agi.com/docs/model-settings.md): Per-model controls, shown exactly as each model accepts them - more than 40 parameters: native search, temperature, reasoning effort, verbosity, and which level wins. - [Guides: Context windows, request limits, and timeouts](https://big-agi.com/docs/context-and-limits.md): How much a model can hold, how large a request can be, how long it can run, and how to get past each. - [Privacy & Account: Accounts, Pro, and billing](https://big-agi.com/docs/account-pro.md): Signing in and out, what Pro costs and adds, how to upgrade or cancel, where invoices live, and what happens to your data when you stop paying. - [Privacy & Account: Back up, restore, and import](https://big-agi.com/docs/account-backup.md): Save your chats and settings as files, read them back on a new machine or from Big-AGI v1, share a chat as a link, and know what the files leave behind. - [Privacy & Account: Delete your data](https://big-agi.com/docs/account-delete.md): Delete one conversation, wipe this browser, close a hosted account by request, every action that erases local work, and what deletion here cannot reach. - [Privacy & Account: Key storage](https://big-agi.com/docs/key-storage.md): Where your key is stored, what someone could do with it, and the rotate-and-revoke steps to run the moment you think it leaked. - [Privacy & Account: What leaves the browser](https://big-agi.com/docs/privacy-data-flow.md): What stays in the browser, and what each feature sends and to whom - with the rows Direct Connection takes off the server path, and the inspector to verify it all. - [Fix problems: Error messages in the chat](https://big-agi.com/docs/issue-messages.md): Find the exact message on your screen, look it up here, and how to fix it. - [Fix problems: "Incorrect API key", "insufficient_quota", and other refusals](https://big-agi.com/docs/issue-key-and-access.md): A credential the AI service refused, or a 429 with money behind it: which layer said no, whether waiting helps, and what to click in which console. - [Fix problems: Where did my chats go?](https://big-agi.com/docs/issue-missing-chats.md): Your conversations live in this browser. Which situation you are in, what can still be recovered, and what cannot. - [Open: Self Host: Run it yourself](https://big-agi.com/docs/self-host.md): What the Open branch gives you, which pieces hosted operates that you configure yourself, and every way to install, verify and update your own instance. - [Open: Self Host: Environment variables](https://big-agi.com/docs/self-host-configuration.md): Every environment variable the Open branch reads and where to set it, plus the access control, reverse proxy and HTTPS an exposed instance needs. - [Open: Self Host: Turn on the optional services](https://big-agi.com/docs/self-host-optional-services.md): Page fetching, search, voice, drive import, and share links are server-provided on hosted. What each one needs on your instance. - [Open: Self Host: My self-hosted instance is broken](https://big-agi.com/docs/self-host-issues.md): Symptoms on an instance you run: a build that stops, a variable that does nothing, egress that fails, a proxy that buffers, and a lockout you built yourself. ## Blog - [2.0.5 · Roberto](https://big-agi.com/blog/release-2.0.5-roberto): Release · Named after my father, on his birthday. - [2.0.4 · Hyper Params](https://big-agi.com/blog/release-2.0.4-hyper-params): Release · Precision matters. - [2.0.3 · Red Carpet](https://big-agi.com/blog/release-2.0.3-red-carpet): Release · What's New. - [2.0.2 · Speex](https://big-agi.com/blog/release-2.0.2-speex): Release · What's New. - [2.0.1 · Heavy Critters](https://big-agi.com/blog/release-2.0.1-heavy-critters): Release · What's New. - [2.0.0 · Open, Free and Pro](https://big-agi.com/blog/release-2.0.0-open-free-and-pro): Release · A year in the making, redesigned for professionals. - [1.16.0 · Crystal Clear](https://big-agi.com/blog/release-1.16.0-crystal-clear): Release · Clarity and transparency in your AI interactions. ## Company - [Source code](https://github.com/enricoros/big-agi): MIT-licensed core.
