This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026. [Pricing](https://headlessthrones.com/models/gpt-rosalind-research#model-answer-pricing) · [Exact model](https://headlessthrones.com/models/gpt-rosalind-research#model-answer-identity) · [Access](https://headlessthrones.com/models/gpt-rosalind-research#model-answer-access) · [Model details](https://headlessthrones.com/models/gpt-rosalind-research#model-answer-research) ### How much does GPT-Rosalind cost? The recorded token rates for GPT-Rosalind are: - **Input:** US$5 per 1 million input tokens. [Source](https://developers.openai.com/api/docs/pricing.md) - **Output:** US$25 per 1 million output tokens. [Source](https://developers.openai.com/api/docs/pricing.md) **Rate conditions:** USD per million input/output tokens in the life-sciences model table. Cached input is $0.50 per million; cache-write pricing does not apply. Regional data-residency pricing can differ. Access requires approval. [Source](https://developers.openai.com/api/docs/pricing.md) **Illustrative arithmetic:** 10,000 input tokens plus 2,000 output tokens would cost US$0.1 at those recorded rates. This assumes every token is billed at the displayed rate and excludes any cache, batch, tool, storage or tier adjustments; it is not a quote or measured usage. Check the source's pricing conditions before budgeting. A token rate does not state the price of an app subscription or the full cost of running downloaded weights. ### Which GPT-Rosalind does this page describe? GPT-Rosalind is a model record from **OpenAI** in the GPT family. [Source](https://developers.openai.com/api/docs/models) The recorded model identifier or checkpoint is `gpt-rosalind-research`. Use that exact identifier when checking documentation or a provider listing. [Source](https://developers.openai.com/api/docs/models) ### How can you access GPT-Rosalind? The catalog documents **API** access for GPT-Rosalind. [Source](https://developers.openai.com/api/docs/models) As of the catalog check, this version was listed without confirmed general availability. [Source](https://developers.openai.com/api/docs/models) For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription. ### What distinguishes GPT-Rosalind? These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results. **Restricted research access**: OpenAI limits access to approved internal research through its trusted-access program; the catalog entry is not an unrestricted self-serve API offer. [Source](https://developers.openai.com/api/docs/pricing.md) **Billing start**: The pricing notice says billing for this exact research identifier began on 2026-10-05. That is a billing date, not a claimed release date or training cutoff. [Source](https://developers.openai.com/api/docs/pricing.md) **Exact research API pricing**: The life-sciences pricing row names gpt-rosalind-research at $5 input, $25 output and $0.50 cached input per million tokens. This quote is restricted to approved research access; regional data-residency pricing may differ. [Source](https://developers.openai.com/api/docs/pricing.md) **Catalog qualifications:** Vendor catalog lists this specialized life-sciences reasoning model for approved organizations. Specs and date fields remain unverified. **Evidence still missing here:** context or input capacity and knowledge and training-data cutoffs. Missing documentation is not evidence that a feature is unavailable. Headless Thrones has not independently benchmarked this model for this reference. Evaluate it on representative work before choosing it; these facts do not rank its accuracy, reliability, speed or suitability against another model. Keep the exact version in view ## Other GPT models from OpenAI. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [Chat Latest](https://headlessthrones.com/models/chat-latest) API · 400,000 context tokens ### [GPT-5.2](https://headlessthrones.com/models/gpt-5-2) API · 400,000 context tokens ### [GPT-5.2 Pro](https://headlessthrones.com/models/gpt-5-2-pro) API · 400,000 context tokens ### [GPT-5.4](https://headlessthrones.com/models/gpt-5-4) API · 1,050,000 context tokens ### [GPT-5.4 Mini](https://headlessthrones.com/models/gpt-5-4-mini) API · 400,000 context tokens ### [GPT-5.4 Pro](https://headlessthrones.com/models/gpt-5-4-pro) API · 1,050,000 context tokens
