Connect any model
AtomCut is not tied to one AI company. Connect the models you already pay for — or a free one on your own computer — and switch between them in the middle of a chat. Media jobs (images, video, voice, sound) route to whichever provider you pick for each.
Add a connection
Agents ▸ Connect a model (or ⋯ ▸ Connections). Pick a provider, paste its key, press Test. A green check means a real request made the round trip — key, endpoint, model and browser access all at once. Providers that list their models refresh the list live, so new models appear without an AtomCut update.
Chat models
| Provider | Key from | Good for |
|---|---|---|
| Anthropic (Claude) | console.anthropic.com | The strongest agent for long, careful, multi-step edits. Opus 5.5 is the default; Sonnet 5 for speed. |
| OpenAI | platform.openai.com | GPT-6 — plus images (GPT Image), video (Sora), voices and Whisper transcripts on the same key. |
| Google Gemini | aistudio.google.com | Gemini — plus Nano Banana images, Imagen, Veo video and Gemini voices on the same key. |
| OpenRouter | openrouter.ai/keys | Hundreds of models behind one key. |
| xAI · DeepSeek · Mistral · Groq · Together | their consoles | Grok, DeepSeek, Mistral, fast open models (Groq also transcribes). |
| Ollama · LM Studio | none | Free and private — models on your own computer. For Ollama allow the site: OLLAMA_ORIGINS=https://app.atomcut.net ollama serve |
| Custom endpoint | — | Anything that speaks the OpenAI API: vLLM, LiteLLM, Azure, a company gateway. |
A Claude or ChatGPT subscription is not an API key — API usage is billed by the provider separately. Smaller local models are weaker at long, tool-heavy tasks; a text-only model is told when it cannot see a render instead of being sent one.
Media providers
| Provider | What it adds |
|---|---|
| fal | Every media job on one key: Nano Banana Pro, FLUX.2, Veo 3.1, Kling 3, Sora 2, background removal for images and video, Topaz upscaling, ElevenLabs voices, sound effects and music. |
| ElevenLabs | Eleven v3 voices, Scribe transcripts, sound effects, music, voice clean-up and lyric timing (forced alignment). |
| OpenAI · Google | Images, video and voices on your chat key (above). |
A media-only connection never becomes the chat model — pair it with a chat connection.
Route each job
Each connection's page has Also use it for: switch on the jobs it should do — images, video, voiceover, transcripts and captions, sound effects, music, background removal, voice clean-up, upscaling, lyric timing. Pick a model per job, or leave Best fit for each job: it chooses the model that takes what the job hands it — an edit model to change a picture, an image-to-video model to animate a still.
Where your keys live
On this device, in the browser's storage, sent only to the provider they belong to. AtomCut's servers never see them.
