Your license does not decide whether an AI agent uses your software. Whether the agent can get it running does — and whether it gets a plain-English error when it hits a wall: of the three attempts in ten that fail on the first try, two retries with the error message recover nine in ten
This issue arrived about 2 hours later than usual today — apologies for the delay.
The one choosing your tools is switching from your users to an AI, and the AI only knows the software it saw in training. Proprietary software vendors just gained a competitor they never had before: open-source tools

1. One model, one change of evaluation setup, 91 → 99: model acceptance testing has to hap…
You cannot subtract one AI lab's revenue from the other's: Anthropic books the money owed to its cloud partners as its own revenue, OpenAI nets it out first. The market spent yesterday building a US$2T valuation on the unadjusted figure
This issue reached you a few hours later than usual, and the fault is ours. Our quality-ch…
NVIDIA's lead over AMD can finally be measured in public, by anyone re-running the numbers — and the cleanest dividing line is not speed; it is one software interface AMD went a generation without

Compute is not one market: over the same stretch, single-card spot ran US$4.22 an hour, last-generation annual contracts US$2.35, and Google's rack-scale lease from SpaceX backs out to US$11.6. Name the layer before you argue about direction
1. A third compute price reaches our records: a rack-scale long-term lease backs out to US…

Atlassian (the enterprise collaboration company behind Jira and Confluence) cut its total …
Washington just barred every "foreign-produced" advanced robot — and the order never names a country. Headlines said "China ban"; that one word decides whether Japanese, Korean, and European robot makers are headed for the Pentagon's door
The US Federal Communications Commission added the entire class of "foreign-produced advan…
Kimi K3 put its 2.8 trillion parameters on the table — weights, tech report and all — and a veteran who has trained a 175-billion-parameter model took it apart section by section. Her verdict: nearly every architecture choice is a bandage holding down numerical blowup at scale. The frontier bar is moving from "who has the secret" to "whose engineering is faster"
Kimi K3, the flagship model from China's Moonshot AI, opened its weights and published its…
The open-weights letter grew to 270 signatories in ten days — read the list backwards: the absentees, Amazon and Anthropic, are the signal

Kimi K3, the flagship model from the Chinese AI company Moonshot AI, has weights anyone ca…
AI productivity can't be measured — and the vendor just said so: OpenAI's productivity lead names the usage metrics that no longer work, and an independent analyst adds the structural reason the gains get competed away even when you can measure them
The people selling AI just said, out loud, "we haven't figured out how to measure producti…
Stop reading hyperscaler capex headlines as an AI supply-chain order book: satellites, robots, and in-house chips all hide inside the same number — the share that actually reaches the AI silicon chain is the yardstick to track

The AI industry produces a hundred headlines a day; the ones that should actually change a decision usually number fewer than five. The daily brief finds them: things that really happened in the last day or two, with receipts attached, each one stating what decision it changes. When a story is hot but rests on a single source, we say so by name — and we print what we chose to skip, right at the top. Around the main stories run five standing desks: chips and semiconductors, expert takes, model research, product moves, and past calls revisited. Five minutes covers what today was actually worth remembering. How we verify it — the methodology
