Mistral ships open-weights flagship + Anthropic eyes $900 billion

Mistral released Mistral Medium 3.5, a 128-billion-parameter dense model with a 256,000-token context window, available open-weights under a modified MIT license at $1.50 / $7.50 per million input/output tokens. The release pairs with Vibe remote agents — async cloud coding agents launched from CLI or Le Chat that handle refactors and test generation in parallel. Reported benchmarks: 77.6% on SWE-Bench Verified, 91.4 on τ³-Telecom, and self-hosting on as few as four GPUs.

TechCrunch reports Anthropic is finalizing a roughly $50 billion raise at a $900 billion-plus valuation, with allocations due within 48 hours and the round expected to close in two weeks. If the numbers hold, Anthropic would surpass OpenAI's $852 billion February post-money mark — a notable inversion for a company that's been the smaller-cap challenger across the frontier-model duopoly. The reporting cites unnamed sources; Anthropic declined to comment.

DeepMind announced an "AI co-clinician" research initiative built on Gemini and Project Astra, structured as a triadic care model where the AI works alongside a supervising physician with a separate "Planner" module monitoring safety boundaries. Academic collaborators include Harvard Medical School and Stanford Medicine, with phased trusted-tester evaluations planned across the US, India, Australia, New Zealand, Singapore, and UAE. It is research, not yet approved for clinical diagnosis or treatment.

Cadillac, Chevrolet, Buick, and GMC vehicles from 2022 onward — roughly 4 million cars — start receiving Gemini as a free over-the-air update, replacing the older Google Assistant. The headline feature is Gemini Live's open-ended voice mode, activated by "Hey Google, let's talk," covering directions, climate, music, vehicle diagnostics, and message summaries. TechCrunch notes the announcement language doesn't limit Gemini to GM, suggesting more automakers to follow.

In opening-week testimony for his lawsuit against OpenAI, Elon Musk acknowledged xAI used distillation on OpenAI models when training Grok, calling it "a general practice among AI companies" and answering "partly" when pressed for a direct yes. Distillation — querying a competitor's API to teach a smaller model — has been associated mainly with Chinese labs in public discourse; the partial admission shifts that frame and raises live questions about terms-of-service compliance.

Swedish legal-AI startup Legora closed a $50 million Series D extension led by NVentures (NVIDIA) and Atlassian at a $5.6 billion post-money valuation, claiming over $100 million ARR and 1,000+ law firms across 50 markets. Harvey still leads at an $11 billion valuation with 100,000 lawyers and 1,300 organizations as customers. Both companies are launching celebrity ad campaigns — Harvey with Gabriel Macht, Legora with Jude Law — and expanding into each other's geographies.

Stripe updated its Link wallet to let autonomous AI agents make purchases on a user's behalf without ever seeing payment credentials. When an agent needs to pay, it generates a spend request the user approves through an in-wallet notification, and Link then routes the credential. Agentic tokens, stablecoin support, and per-agent spending limits are listed as "coming soon." This is the first programmable-payment surface engineered around the agent-as-shopper pattern from a top-tier processor.
