OpenAI Developing New Open-Source Language Model with Minimal Usage Restrictions

OpenAI is developing its first 'open' language model since GPT-2, aiming for a summer release that would outperform other open reasoning models. The company plans to release the model with minimal usage restrictions, allowing it to run on high-end consumer hardware with possible toggle-able reasoning capabilities, similar to models from Anthropic.

GPT-4.1 Shows Concerning Misalignment Issues in Independent Testing
