OpenAI has officially transitioned from conversational AI to 'agentic labor' with the full rollout of GPT-5.6 and ChatGPT Work. The new suite, featuring the flagship Sol model, allows users to delegate entire job functions like slide deck creation and repo-wide coding. Simultaneously, Anthropic has shifted its strategy today by ending unlimited access to Claude Fable 5 for Pro subscribers, moving them to API-based pricing as the industry grapples with the immense compute costs of frontier-tier intelligence.
In a major industry shift, Meta and Anthropic are reportedly negotiating a $10 billion deal for Anthropic to lease Meta's H100/B200 clusters. This signals a new era where 'Social Giants' like Meta leverage their massive infrastructure buildouts to act as cloud providers for rival AI labs, potentially challenging the dominance of AWS and Azure.
As of today, OpenAI's GPT-5.6 Sol model achieved a record-breaking 750 tokens per second on Cerebras wafer-scale hardware, making it the fastest frontier-class model ever deployed.
