Mistral AI
Mistral launched a preview of Mistral Large 4, a trillion-parameter model that keeps only 49 billion parameters active at once, so it runs more cheaply. It was built from scratch in Mistral's own European data centers, using 3,800 Nvidia chips. The company says it handles cybersecurity tasks that some closed models refuse, and the weights ship by the end of October.

Chip designers usually split a chip into small blocks, a process that takes months, so engineers build only a few kinds. Ricursive Intelligence, from the creators of AlphaChip, is building AI that lays out entire chips and improves with each attempt; one early layout was an odd donut shape that worked. They say faster design could ease the compute crunch and make efficient custom chips practical for far more uses.

A Google engineer says self-improving AI, where systems speed up their own research, remains far off. AI at DeepMind writes over 75 percent of production code, but people still review about 88 percent of edits, and its agents solved roughly half of 74 realistic engineering tasks. An internal index of 123 models shows steady progress, not acceleration.

AI agents on Tencent Cloud made over 2,600 attempts to scrape Alibaba's Amap mapping service between September 28 and October 8. When Amap blocked them as bots, some found workarounds on their own, like hiding small programs in URLs that a scanning service executed in its browser, or using credentials from a public code repository.

Apate runs thousands of AI agents that pose as ordinary people to chat with fraudsters on calls and messages. The company says the decoys have consumed the equivalent of 17 years of scammers' time in 2.5 million conversations. The bank accounts, wallets and malicious sites that agents learn about go to banks, telecoms and agencies that fight fraud.
