GPT-5.6 becomes default model in Microsoft 365 Copilot as OpenAI touts coding capabilities
OpenAI's GPT-5.6 has been named the preferred model in Microsoft 365 Copilot, deepening the companies' enterprise partnership. Sam Altman announced the integration directly, and the reception from users has been enthusiastic enough that Altman followed up noting how much people love the model, nicknamed Sol. Developers have been fielding questions about the release in a live AMA covering GPT-5.6, Codex in ChatGPT, and computer use features.
Observers are still working out how to best use the model, with developer Simon Willison noting that Sol on Medium reasoning effort may be a strong new default for coding tasks, potentially surpassing the previous favorite GPT-5.5 on extra-high effort. OpenAI also highlighted a real-world coding case where GPT-5.6 autonomously handled a nearly 1,000-line task for an engineer at Snorkel AI without repeated prompting.
OpenAI doubles bio bug bounty rewards to $50K in expanded biosecurity program
OpenAI is evolving its Bio Bug Bounty into a permanent private program and doubling the maximum reward to $50,000, as part of what the company describes as ongoing efforts to strengthen safeguards around advanced AI capabilities in biology. The expanded program will invite researchers with relevant expertise to probe the company's biological safety measures on a continuing basis rather than through a time-limited bounty.
