Thibault Sottiaux of OpenAI's Codex team announced that GPT-5.3-Codex-Spark will be retired next week, citing declining usage and significantly better models.
The poster speculates the successor could be a GPT-6 Astra Spark: the original delivered 1,000+ tokens/sec, and OpenAI has planned larger multimodal models. At that speed with Astra's computer-use ability, real-time gameplay could replace the hour-long renders of short clips like the famous 3m38s Celeste run. Unofficial speculation, not confirmed.
