A restricted AI model for biological reasoning and scientific tool use. OpenAI announced GPT-6 Rosalind on 30 October 2026 for approved organisations and internal research.

GPT-6 Rosalind is an AI model intended for biological reasoning and working with scientific tools. OpenAI’s 30 October 2026 changelog describes restricted access for approved organisations and internal research.

Access is tied to approved research

The release identifies the model as gpt-6-rosalind. Access conditions are part of the product: researchers need approval for the applicable use and environment. The announcement describes a specialised scientific model rather than a public consumer release.

Token prices depend on the request

OpenAI’s pricing page, checked on 9 November, lists standard short-context rates of $15 per million input tokens, $1.50 for cached input and $75 for output. Long-context and cache-write charges follow their own pricing categories.

Scientific answers still need validation

A model can help organise a scientific question and work through information supplied to it. Researchers should check generated claims against source material, inspect tool outputs and validate conclusions using the methods appropriate to their study. Access to a specialised model is one part of that process.
