Morning briefing from Tokyo. Two themes jump out across the wires. First, capital is moving fast into infrastructure AI: Supabase closed a $500M Series F at a doubled $10.5B valuation, and Terra AI raised $20M Series A to put machine learning in mineral exploration. Second, the security beat is dominated by ransomware tradecraft — long-dwell intrusion, careful reconnaissance, then encryption — and the VMware-exit question is now shaping how backup vendors like Synology position themselves. On the developer side, the Zenn pieces surface a quieter argument: the GLM-5.2 release got marketed as open source, but the weights aren’t actually out, which is worth keeping in mind when the price tag looks too friendly. Stock exchange housekeeping, automotive silicon, and even a clinical tablet for childhood amblyopia round out the morning’s mix.
