# The speed numbers are the ones worth keeping.

## Retrieval answer

**Thesis:** The operational value of this update is not only a faster first response; it is the pairing of a latency claim with a published safety and capability assessment.

**Thesis:** The operational value of this update is not only a faster first response; it is the pairing of a latency claim with a published safety and capability assessment.

**Observed facts:** OpenAI’s October 7 system card says GPT-6 Sol and GPT-6 Luna replace GPT-5.6 Sol and GPT-5.6 Luna in ChatGPT, while Codex and ChatGPT Work remain on earlier versions. It reports that GPT-6 Instant begins answering 44% sooner than GPT-5.6 Instant on web-search questions. OpenAI also reports improved resistance to multi-turn jailbreaks and classifies the October models as High capability in cybersecurity and biological and chemical domains.

**Mechanism:** A first-token or answer-start improvement can reduce perceived waiting, while deployment-specific versions mean the headline model name does not guarantee every OpenAI surface is running the same release. The system card makes those boundaries visible alongside the company’s safety evaluations.

**Why now:** The update is framed as a broad ChatGPT rollout, but the stated exceptions for Codex and Work make product-surface tracking important now.

**Implications:** Teams should verify which model version serves each workflow before attributing latency or safety changes to “GPT-6” generally. The reported speed gain applies to web-search questions and answer start, not all tasks or completion time.

**Evidence boundary:** These performance and safety statements come from OpenAI’s own deployment-safety publication; the supplied evidence does not establish independent replication or generalize the 44% figure beyond the specified comparison.

**Watch condition:** Watch for confirmation that Codex and ChatGPT Work move to the October versions, and for comparable measurements on other task types.
