OpenAI debuts a research preview of GPT-5.3-Codex-Spark, a smaller version of GPT-5.3-Codex that it claims generates code 15 times faster, for ChatGPT Pro users
ZDNET's key takeaways — OpenAI targets “conversational” coding, not slow batch-style agents. — Big latency wins: 80% faster roundtrip, 50% faster time-to-first-token.

ZDNET's key takeaways — OpenAI targets “conversational” coding, not slow batch-style agents. — Big latency wins: 80% faster roundtrip, 50% faster time-to-first-token.
OpenAI launches GPT-5.3-Codex, which it says runs 25% faster, enabling longer-running tasks, and “is our first model that was instrumental in creating itself”
ZDNET's key takeaways — GPT-5.3-Codex helped debug and deploy parts of itself. — Codex can be steered mid-task without losing context.
