gpt-5.3-codex-spark missing from OpenAI models with ChatGPT OAuth #25638
Description
Description
openai/gpt-5.3-codex-spark is no longer listed for the OpenAI provider when OpenAI is connected through Codex/ChatGPT OAuth.
The model is present in models.dev.
This appears to be a regression from #25157
I also checked the broader OpenAI Codex candidate list and gpt-5.3-codex-spark was the only missing working model found.
Plugins
Built-in Codex/OpenAI OAuth auth plugin
OpenCode version
1.14.31
Steps to reproduce
- Connect OpenAI using Codex/ChatGPT OAuth.
- Refresh and list OpenAI models:
opencode models openai --refresh - Search for:
openai/gpt-5.3-codex-spark - Observe that it is missing.
Expected: openai/gpt-5.3-codex-spark appears in the OpenAI model list when using Codex OAuth.
Actual: The model is omitted by the Codex OAuth model filter.
