Jev reached 35% of paid teams within two weeks of launch, the fastest adoption recorded by Vercel and nearly twice the reach of Sonnet 5.5. Typesafe AI’s lightweight decision model selects among predetermined outputs for cheaper, faster classification. The figures come from Vercel’s AI gateway, which may undercount providers with their own APIs; open-source models now represent more than 70% of gateway tokens and nearly 25% of spending.
We are hosting our first "Bench Summit" to bring together people excited about pushing the frontier of benchmarking, model evals, and more. Great benchmarks are a gating function for model progress, lots to do here! Join us in SF: https://t.co/7qqyPLe5Vp
Arena, a crowdsourced AI model leaderboard, raised $200 million in a Series B round at a $3.1 billion valuation. The round was co-led by Lightspeed Venture Partners and Khosla Ventures, with participation from Salesforce Ventures, 01 Advisors, Dell Technologies Capital, Endeavor Catalyst, a16z, Felicis, and others.

Good Start Labs turned the 1830 railway board game into a training environment for experiments with 30B models. Both single-turn question-and-answer and multi-turn terminal-agent training improved performance in the game, but only the terminal-agent setup improved results on the Finance-Agent benchmark. The company, spun out of Every and funded with $3.6 million, argues that how a game is presented determines which skills a model learns and whether they transfer to work outside games.
The alignment team at the UK's AI Security Institute and Timaeus have jointly founded Sequent, a nonprofit research organization. It argues that “alignment is not on track” and plans to grow to 40–80 full-time staff within two years, with an initial fundraising target of $100–150 million. Research areas include scalable oversight, learning theory, heuristic argumentation, game theory, and personas.
