We have big moves in compute, gadgets, and models — let’s get to it.

Anthropic taps SpaceX for massive compute

Big picture: Anthropic struck a major partnership to use SpaceX’s Colossus One data center and more than 300 megawatts of capacity.

• What’s changing: The deal is already easing rate limits for Claude Code on Pro, Max, and Team plans, removing peak-hour throttling, and raising API limits for Opus models.
• Why it matters: Think of it as giving Anthropic a much bigger engine and fewer traffic jams.

Google launches Fitbit Air — a screenless AI health band

Big picture: Google unveiled Fitbit Air, a lightweight, screenless tracker with up to a week of battery life.

• Features: Delivers deep Google Health insights on heart rate, HRV, blood oxygen, recovery, and more.
• Positioning: No subscription, no distracting screen — aiming to offer Whoop-style health tracking at a fraction of the cost.

OpenAI rolls out GPT-5.5 Instant to everyone
