PR zed-industries#62502 changed the ChatGPT subscription models to report the corresponding public API context windows. That was based on a mistaken assumption: subscription requests go through the separate Codex backend, which still rejects requests around the previous context limit. Because the advertised context window also determines when Zed compacts a conversation, reporting 1.05M tokens delays compaction until after the Codex backend rejects the request. This reverts zed-industries#62502 and restores the previous conservative limits. Longer term, we should load the account-specific model metadata from the Codex `/models` endpoint rather than maintaining this list by hand. Release Notes: - Fixed automatic context compaction for GPT models accessed through a ChatGPT subscription.
