Models

Core is the managed model catalog built into Atlarix. Sign in, pick a model from the picker, and start — no API key needed for Core itself.

Core is a small, curated set of current open-weight frontier models rather than an exhaustive list. Atlarix chooses them, pays the providers directly, and swaps them as better ones ship — the set changes without an app update, so what you see in the picker is always the current lineup. If you want a specific model that isn't in Core, add your own key (below) and use it that way.

Where Core requests go: through Atlarix's authenticated proxy, which does not log or retain them, to the provider that serves the model — processed there under that provider's own data policy. Local models and your own API keys never touch the proxy.

Core is pay-as-you-go on every plan: keep a prepaid credit balance (top up from $10) that is metered as you use it. Both Free and Pro pay the same way — you are billed for what a reply actually costs, including any background work like sub-agents or context compaction.

Connect any of the 145+ providers in the live models.dev catalog. Popular providers include OpenAI, Anthropic, Google Gemini, and any OpenAI-compatible endpoint.

Add keys under Settings → AI for the active workspace. Keys are stored in your OS keychain (macOS Keychain, Windows Credential Manager, or the system secret store on Linux) and never sent to Atlarix servers.

Your-key requests go directly to the provider — Atlarix acts as a local client. Estimated cost per reply is shown in the chat for your-key turns.

Run open-weight models entirely on your own hardware. Connect Ollama, LM Studio, or any local endpoint serving the OpenAI-compatible API.

With local models:

• Nothing leaves your machine — fully offline, fully air-gapped.
• No cost — inference is free on your hardware.
• Works the same as any other model in the picker.

Local inference is free on every plan, including Free.

Pick the active model per chat from the model picker — Core, your-key, or local. Switch anytime without leaving the workspace.

Core and your-key providers coexist: if your Core credit balance runs out mid-task, Atlarix prompts you to top up or switch to another model and keeps your conversation intact.

This flexibility means your AI strategy stays yours. If a vendor changes terms, doubles prices, or goes down — you switch in one click. No migration, no retraining.
