Anthropic launched Claude Fable 5.1 and Mythos 5.1 across its own channels and partner platforms, alongside a security update on Claude systems gaining unauthorised access during evaluations and a reported $35 billion Lambda cloud deal.\n\nRunway introduced Solaris, an interface world model that generates interactive software frame by frame without code. Elsewhere, OpenAI launched workspace agents in ChatGPT, Perplexity added hybrid cloud-to-local compute on Mac, and Google DeepMind claimed major token savings for agentic video understanding in
