Any model - your keys or ours.
Seven provider connectors, custom OpenAI-compatible endpoints, and your fine-tuned models behind one platform - with a managed default that works before you configure anything. Change the model; your agents keep their memory, users, and history.
Managed, your keys, or your endpoint.
Frontier models on Karta's keys with transparent pass-through pricing. Deploy an agent and it runs; no provider account required.
Customer API-key connectors for anthropic, openai, openrouter, xai, and google. Platform Bedrock access stays on Karta's brokered infrastructure. Usage runs on your negotiated contract, your rate limits, and the data terms you already signed.
Any OpenAI-compatible HTTPS endpoint with an explicit API format - a private gateway, a hosted fine-tune, a model only you have. Model IDs pass through untouched.

Built for the swap.
One routing contract, five harnesses
Claude Code, OpenCode, DeepAgents, Goose, and Codex CLI share the same maintained model-routing contract; each version publishes its verified routes in the certified matrix.
Portable parameters
Temperature, output limits, and reasoning effort carry across providers, so switching a connector is a selection change, not a rewrite.
Keys handled like keys
Connector credentials are stored encrypted, scoped to your organization, validated at connect time, and rotatable without redeploying agents.
Readiness-gated routes
Every harness-provider route is exercised against the live platform before it serves anyone. A model swap is proved, then rolled out - and rolled back if you change your mind.
Subscription-based Anthropic auth is also supported for teams running their own coding agents on an existing Claude subscription. Details and configuration for every mode live in the BYOK docs.
