WHAT SHIPPEDOpenAI released a research preview of GPT-5.3-Codex-Spark, a smaller GPT-5.3-Codex model that delivers more than 1000 tokens per second on Cerebras hardware, with a 128k context window and text-only input.
THE CATCHThe speed comes from a latency-first serving tier on Cerebras Wafer Scale Engine 3, and the same pipeline work cut time-to-first-token by 50% for all models, not just Spark.
