OpenAI just announced it will reset rate limits twice across ChatGPT Work and Codex over the next 24 hours to celebrate the launch of GPT-5.6 Sol. The temporary boost gives users extra breathing room to test ambitious tasks and get familiar with the new model without constantly bumping into usage caps. Why it matters: If you have heavy workloads lined up, today is the day to push the new model to its limits.
OpenAI just launched the GPT-5.6 family for general availability, featuring flagship Sol, balanced Terra, and low-cost Luna. Sol hits a state-of-the-art 53.6 on Agents' Last Exam, outpacing Claude Fable 5 by 13.1 points while cutting costs. It also introduces an "ultra" mode running four parallel agents to crush heavy workloads faster.
OpenAI just announced that three new GPT-5.6 model variants — Sol, Terra, and Luna — are officially launching publicly this Thursday. The company is already expanding preview access globally ahead of the rollout. While OpenAI hasn't shared specific specs for each variant yet, dropping all three at once signals a major push for the GPT-5.6 family.
OpenAI just launched GeneBench-Pro, a challenging research-level benchmark designed to measure how AI agents navigate ambiguity and messy datasets in computational biology across 129 tasks. Using synthetic data with known causal structures for deterministic grading, GPT-5.6 Sol scored a 28.7% pass rate—up sharply from GPT-5's sub-5% run on the original benchmark. Ten sample questions are live on Hugging Face.
OpenAI just launched a limited preview of its new GPT-5.6 model family, led by the flagship Sol alongside Terra and Luna. Sol introduces an ultra multi-agent mode and deeper reasoning to tackle complex coding, biology, and cybersecurity workflows. At the U.S. government's request, rollout starts with a select group of trusted partners before expanding broadly.
