5.6sol 1m context change does not take effect - Codex

Quick fix

There is no maintainer-confirmed cause or fix, so it is unclear whether gpt-5.6-sol supports a 1m context.

Symptom

Section titled “Symptom”
Error output
responses下的5.6sol更改1m上下文就是不生效，反而terra和luna可以
English translation

Under responses, changing the 5.6sol context to 1m does not take effect, while it works for terra and luna.

Cause

Section titled “Cause”

On Windows with cc-switch 3.20.0, the user uses a custom provider through Codex's Responses (native) format and sets `model_context_window = 1000000` and `model_auto_compact_token_limit = 900000`. The same settings work for terra and luna but not for gpt-5.6-sol.

The issue remains open, and neither a maintainer nor another user has confirmed the specific cause. The available evidence therefore cannot determine whether the problem lies with cc-switch, Codex, the model's capabilities, or the custom provider.

Fix

Section titled “Fix”

  1. There are no confirmed fix steps for this issue. Until a maintainer or the provider clarifies gpt-5.6-sol context support, do not treat unverified configuration changes as a solution.
