Supporting a shared AI training control for websites

AI summary Google says it will recognize a common robots.txt 'policy token' that lets sites state AI training preferences for several AI providers at once, drawing on the IETF's AIPREF working group. If a site opts out with this token and does not mention Google-Extended, Google will treat it as a block on Google-Extended, its own training control available since 2023. Company-specific controls will keep working alongside the shared signal. Google aims to support the mechanism together with other AI providers in 2027.

API credits benefit for eligible ChatGPT subscriptions

AI summary OpenAI has introduced a perk giving customers on its $100, $200 and $500 monthly ChatGPT plans an equal amount of credits each month for use with one of their API organizations. The move closely mirrors an offer Anthropic announced earlier in October 2026 for its Max and Team subscribers, whose credits expire. Developer Simon Willison, who pays for both services, said the credits could let him publish public demos at no extra cost.

We ran AI agent swarms in Minecraft and Mindustry

AI summary Working with Olam Labs, the authors put 50 GPT-6.1 Sol agents into a survival Minecraft world for three hours with an open-sourced harness; the agents exchanged roughly 5,900 messages, built a rationing bureaucracy and grew cautious after 22 of 34 deaths happened on the first night. In nine 45-minute Bed Wars games, 10 GPT 6.1 Sol agents beat 10 Claude Opus 5.5 agents 6–3, typically by destroying Claude's bed late while Claude defended and led on kills. In both setups, the agent listed first in the directory, such as Ada, ended up as leader. In seven Mindustry PvP games lasting about 9.5 hours, the GPT team won 6-1.
