OpenAI is preparing to release an open-weight language model as soon as next week, according to sources. Described as similar to o3 mini with advanced reasoning capabilities, it will be available on Azure, Hugging Face, and rival cloud providers, marking OpenAI's first open-weight model since GPT-2 in 2019.
Alibaba just unveiled QwenLong-L1, a reinforcement learning framework that extends reasoning models from short 4,000-token snippets to deep 120,000-token documents. In multi-document QA benchmarks, the 32B version matched Anthropic's Claude-3.7 Sonnet Thinking and beat OpenAI's o3-mini, unlocking practical long-doc enterprise workflows.
OpenAI just teamed up with Kaggle to launch the OpenAI to Z Challenge, inviting developers to hunt for hidden Amazon archaeological sites using o3/o4 mini and GPT-4.1. Participants must combine open satellite imagery and lidar scans to uncover lost settlements, competing for a $250,000 first prize.
OpenAI just announced plans to release its first open language model since GPT-2 in the coming months, launching a community survey to guide development. CEO Sam Altman revealed the model will pack o3-mini-level reasoning and run directly on your own hardware, marking a major strategy shift amid fierce heat from open-source rivals.
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 updated the chain of thought for o3-mini, revealing far more reasoning steps to both free and paid ChatGPT users. While it still holds back raw internal monologues to prevent distillation, a new post-processing layer cleans up unsafe output and translates the thought process into non-English native languages.
OpenAI CEO Sam Altman just confirmed that the company's upcoming lightweight reasoning model, o3-mini, will be available to all ChatGPT users, including the free tier. Paid Plus subscribers will receive generous usage allocations. The model focuses on faster and cheaper math and coding reasoning, though a specific launch date has not been set.
Sam Altman just announced that OpenAI has finalized o3-mini and started its rollout process, targeting a launch in about two weeks. Addressing developer demands, the team plans to release the model on both the API and ChatGPT at the exact same time.
OpenAI just capped off its 12 Days of OpenAI event by revealing its next-generation reasoning model, o3, alongside o3 mini. The new models comfortably beat o1 on math, coding, and the ARC-AGI benchmark, featuring adjustable reasoning effort. General users will have to wait, though, as rollout begins in late January.
