Changes
GPT-5.3-Codex-Spark is deprecated
Effective date: · OpenAI
When its research preview opened to Pro on February 12, OpenAI said Spark's usage had limits of its own and did not count against the standard Codex limits. The plugin counts its tokens like any other, so a week with Spark in it can read high: more tokens than the weekly limit held. It is no longer available in the app, CLI or IDE extension.
