Anthropic releases Opus 4.8 and launches IPO, Microsoft introduces MAI model series, MiniMax-M3 surpasses GPT-5.5 and Gemini 3.1 Pro at a fraction of the cost. Meanwhile, policy sees voluntary testing framework and export control tightening.
Anthropic released Claude Opus 4.8, which shows improvements on benchmarks and introduces Dynamic Workflows, a tool for executing long-running multi-agent tasks. Its system card discusses eval-awareness findings and welfare/corrigibility themes.
On the business side, Anthropic completed a $65 billion Series H round at a $965 billion valuation and has filed IPO documents, preparing to go public. Additionally, Anthropic expanded its Mythos project to another 150 organizations.
At Build, Microsoft launched Microsoft Scout, an always-on AI personal assistant based on OpenClaw, and a new MAI model series including MAI Thinking 1. Microsoft emphasized these models' enterprise security architecture and from-scratch training capability.
These releases mark Microsoft's further push into AI assistants and foundation models, competing with Anthropic and OpenAI.
MiniMax-M3 surpasses GPT-5.5 and Gemini 3.1 Pro on key benchmarks while costing only 5-10% of the latter. This performance highlights the trend of open-source/low-cost models catching up to frontier closed-source models.
Released by MiniMax, the model's cost advantage could significantly impact pricing and competition in the AI industry.
Trump signed an executive order establishing a voluntary pre-release government testing framework for powerful AI models. Meanwhile, the US tightened export controls on Nvidia AI chips.
China requires private-sector AI experts to obtain government approval before traveling abroad to retain top talent. Additionally, Meta AI was exploited to hijack Instagram accounts, highlighting AI safety risks.
