What changed in AI agents — and what it costs you
Our reviews answer which tool is best. These answer a narrower, more urgent question: something just moved in this market, and does it change what you should buy this month?
Every story here is tied to a dated event and a primary source — a vendor changelog, a CVE record, a benchmark repository, an official register. Each was researched once, then re-checked by a second reader who had not seen the first pass and had to open every link again. Three came back wrong on the second pass and were corrected before they were written; the corrections are noted in the articles themselves. 10 articles, 31 distinct sources.
Where an article shows a chart, every value on it is one measure. Where the numbers in a story were different quantities, there is no chart, because putting a dollar figure beside a percentage draws a comparison that does not exist.

The same coding agents that passed 83.8% of Terminal-Bench 2.1 now clear 33.8%. Nothing regressed; the exam changed, and so should how you read vendor scores.
7 sources · chart 21 July 2026A widely repeated summary of METR’s July 2026 study inverts the definition and narrows the range; the underlying numbers hold, the interpretation does not.

The all-stock purchase of Anysphere closed on 14 August 2026, and the published record confirms far less about pricing and roadmap than buyers will want.
7 sources 26 August 2026Twelve months’ notice, a guided path for assistants, and nothing at all for thread history. What the 26 August shutdown means for teams still exposed.
