openclaw - 💡(How to fix) Fix Add openai-codex support for gpt-5.5-instant [2 comments, 2 participants]

Summary

Please add / expose openai-codex/gpt-5.5-instant in the OpenClaw model catalog and Codex OAuth routing when the model is available for the user's ChatGPT account.

Problem

Some ChatGPT accounts can already select the GPT-5.5 Instant model in the ChatGPT web UI, but OpenClaw currently does not expose an openai-codex/gpt-5.5-instant model ID.

On OpenClaw 2026.5.6, the openai-codex catalog currently includes models such as:

• openai-codex/gpt-5.5
• openai-codex/gpt-5.5-pro
• openai-codex/gpt-image-2

But it does not include an Instant variant. Attempting to call the likely ID fails before reaching a provider request:

Error: Unknown model: openai-codex/gpt-5.5-instant

Expected behavior

If the authenticated ChatGPT account has access to GPT-5.5 Instant, OpenClaw should expose a supported model entry, likely one of:

• openai-codex/gpt-5.5-instant
• or whatever canonical internal model ID the Codex/ChatGPT backend expects for the Instant route

Then users should be able to set or call it via commands like:

openclaw models set openai-codex/gpt-5.5-instant
openclaw capability model run --model openai-codex/gpt-5.5-instant --gateway --prompt "hello"

Current verification

openai-codex/gpt-5.5 works through the gateway with ChatGPT OAuth on the same setup. The missing piece appears to be model catalog / routing support for the Instant variant, not general OAuth connectivity.

Environment

• OpenClaw: 2026.5.6
• Provider: openai-codex
• Auth mode: ChatGPT / Codex OAuth
• Gateway invocation: openclaw capability model run --gateway

Why this would help

GPT-5.5 Instant is useful as a lower-latency default for interactive OpenClaw sessions while keeping gpt-5.5 available for deeper work.
