   Thanks for the clear report, @LESdylan. I can confirm it.

   • On 2.0.18, opencode run -m opencode-go/longcat-2.5-preview-free fails immediately with Model unavailable: opencode-go/longcat-2.5-preview-free, before any request is sent. opencode-go/beam-free is still recognised and goes through to the gateway.
   • The reason is that models.dev now marks longcat-2.5-preview-free as deprecated, and the client hides deprecated models on purpose. That part is working as designed.
   • The Go docs page (https://opencode.ai/v2/docs/console/go/) still lists LongCat 2.5 Preview Free as Unlimited (limited time) for Go and Go Plus. The current dev source (e965774) still has it in the Go docs, the models docs and the console Go page.

   I got the same result on the latest release, 2.1.3. I couldn't check whether the gateway itself still serves the model, because that needs a real Go account. Whether the endpoint comes back or the docs are updated is up to the team. The script below reproduces the client error and the docs mismatch.

   Reproduction script (repro.sh)

   #!/usr/bin/env bash
   # Reproduces #58133: opencode-go/longcat-2.5-preview-free is rejected by the
   # client (deprecated in models.dev) while the Go docs still advertise it.
   # Usage: ./repro.sh            -> uses `opencode` from PATH (e.g. @opencode/[email protected])
   #        OC_DEV=/path/to/repo ./repro.sh -> runs the CLI from a source checkout
