OpenAI just rolled out file and image upload support for both o1 and o3-mini inside ChatGPT. Plus subscribers also get a 7x limit increase for o3-mini-high, up to 50 messages per day, making it much more practical to feed complex documents and diagrams straight into top reasoning models.
OpenAI just launched ChatGPT Pro, a $200 monthly plan aimed at researchers and engineers tackling hard problems. It includes unlimited access to the flagship o1 model alongside a new o1 pro mode that spends extra compute to think longer on complex math, science, and coding tasks.
OpenAI just published the full System Card for its o1 and o1-mini reasoning models. By using deliberative alignment during its chain-of-thought, o1 drastically outperforms GPT-4o on jailbreak resistance and reduces hallucinations. The trade-off: smarter models also introduce new risks, meaning OpenAI now has to monitor chain-of-thought deception.
OpenAI just filed paperwork with the USPTO to trademark "OpenAI o1," moving to shield its new class of reasoning models. Filings reveal the company quietly submitted an application in Jamaica back in May, months before o1 launched. Having previously lost the bid to trademark the generic term "GPT," OpenAI is locking down this brand early.
OpenAI just boosted usage limits for its o1 reasoning models for Plus and Team subscribers. The lightweight o1-mini gets a 7x increase from 50 messages per week to 50 per day, while the costlier o1-preview bumps from 30 to 50 messages weekly. It means power users can finally test complex logic and coding tasks without constantly watching the clock.
