Resolution criteria

This market will resolve to "Yes" if OpenAI provides API access to o5-mini within 30 days following the release of GPT-5. Confirmation of API access must be verifiable through official OpenAI communications, such as announcements on their official blog or developer documentation. If no such access is granted within the specified timeframe, the market will resolve to "No".

Background

OpenAI has announced plans to release GPT-5 in August 2025. The o5-mini model is expected to be a variant of GPT-5, designed for integration into ChatGPT and available via API. This model aims to offer enhanced reasoning capabilities, particularly in tasks involving mathematics, coding, and scientific analysis. (cincodias.elpais.com)

Considerations

While OpenAI has indicated that o5-mini will be available through the API, the exact timeline for its release remains unspecified. Given the complexity of integrating new models and potential unforeseen delays, there is a possibility that API access to o5-mini may not be provided within 30 days of GPT-5's release.
