The catalogue is the source of truth. Browse it at tryorbit.cloud/models or list models through the OpenAI-compatible endpoint.

​
Use the public slug

Pass the catalogue slug as model. Do not pass a Bedrock ARN or provider model id. The native chat route also accepts the catalogue UUID, but slugs are what you should use in SDKs and agents.

​
Vendors

50+ models across these vendors, all served through Amazon Bedrock in us-east-1: Anthropic, OpenAI (including Bedrock Mantle for the newest GPT-5 models), xAI (Grok), Moonshot (Kimi), Meta, Mistral, DeepSeek, Qwen, MiniMax, Google (Gemma). The catalogue grows as new models ship. Check the models page for the live list, context windows, modalities, and vendors.

​
How a request is served

You name a model by slug. Orbit looks it up in the catalogue and sends the request to Amazon Bedrock in us-east-1 at that model’s list rate. The newest GPT-5 models go through Bedrock Mantle. There is no second provider and no failover. Credits are charged after a successful call.

​
Try a model from the dashboard

Open any model in the catalogue and use Try for copy-paste samples (Orbit API, OpenAI SDK, Anthropic SDK) or Playground to chat against it with your signed-in organization.
