ChatGPT Pro

OpenAI has published 372 mathematical results generated by an unnamed internal frontier model, hosted on GitHub instead of in peer-reviewed journals. The company claims each result solves or substantially advances an open problem, at an average of about three hours of ChatGPT Pro Thinking compute per result. Many include Lean formalizations, but independent validation of significance is still pending.

OpenAI is reopening its $200-per-month Pro subscription to new sign-ups while cutting the API credits bundled with it in half. The company also removed the 5-hour usage cap, letting subscribers spend their weekly allotment however they choose.

OpenAI has temporarily disabled new sign-ups for its $200-per-month Pro plan, citing infrastructure strain from unprecedented demand for its Astra model. API, Go, and Plus plans remain unaffected.

OpenAI's Codex desktop app for Mac has added Chronicle, a feature that periodically captures screenshots, sends them to OpenAI's servers for OCR and visual analysis, then stores text summaries as unencrypted Markdown files locally. The feature requires a $100+/month ChatGPT Pro subscription and is unavailable in the EU, UK, and Switzerland.
