OpenAI quietly blocks GPT-6.1 Sol in Codex for $20 ChatGPT plans mid-day
gaspoweredcat · reddit · 2026-10-01
A Reddit user reports that GPT-6.1 Sol worked in Codex this morning, then suddenly failed with "unable to load messages." After reloading, the error reads: "The 'gpt-6.1-sol' model is not supported when using Codex with a ChatGPT account."
It appears OpenAI is not letting $20-tier subscribers use the 6.1 Sol model in Codex, with the restriction taking effect mid-day and without prior announcement—a quiet availability cut that directly affects paying users.
