Available Models

The gateway serves 60 chat routes under their makers' own names, among them:

• claude-opus-5, claude-sonnet-5, claude-haiku-4.5 (Anthropic)
• gpt-6-astra, gpt-5.5, gpt-5.6-luna / -sol / -terra, gpt-5-mini (OpenAI)
• gemini-3.7-flash, gemini-3.1-pro-preview (Google)
• grok-4.5 (xAI), kimi-k3 (Moonshot), glm-5.3 (Z.ai)
• deepseek-v4-pro, deepseek-v4.1-flash (DeepSeek)
• qwen-3-8-max and other Qwen routes (Alibaba) Plus 5 image models and 1 video model on their own endpoints.

Key Features

• one endpoint and one key for models from several makers
• the model id is the maker's own, with no vendor prefix
• an authenticated GET /v1/models publishes per-model prices, context and output limits, and capability flags, so a client can read the catalogue rather than hard-code it
• four models are priced in two bands with a published long-context threshold
• the catalogue moves: four of the 60 routes changed price in the 23 hours between two readings, which is why reading it beats pinning it

Pricing Information

https://cheaperinference.com/docs Per-model rates come from the provider's own GET /v1/models response, which reports both the charged rate and the maker's list price.

Your Use Case

I use this gateway already and want Forge pointed at it without a custom OpenAI endpoint. What I get from it is one key for models from several makers, which matters when a session moves between a cheap model for bulk edits and a frontier one for the hard part - today that means re-configuring the provider mid-session. The models are addressed by their makers' own names, so the same model id works whether I go through the gateway or direct.

Contribution

• I'm willing to submit a PR to implement this integration
• I can help with testing
• I have access to this provider's API for testing

Additional Context

The change follows #3623 (OrcaRouter): an entry in crates/forge_repo/src/provider/provider.json, the ProviderId in crates/forge_domain/src/provider.rs, the repo wiring, and a README row. Models are discovered from the provider's own /models endpoint, so no model list is hard-coded. 618 + 334 tests and clippy are green locally.
