FCC Chairman Brendan Carr’s war on the First Amendment

As the chairman of the Federal Communications Commission, Brendan Carr has authority over the nation’s TV, radio, and internet. But since Donald Trump was elected to his second term, Carr has wielded that power to threaten broadcasters that have exercised their free speech rights to make jokes about the president. He was even able to […]

Show HN: Echo – Fable-level results at 1/3 the cost using open-weight models

I’ve been building Echo ( https://echo.tracerml.ai/ ), an experiment in making one AI system out of a pool of open-weight models rather than choosing a single model and using it for every task. It started with a simple experiment. I took a group of models, including GLM-5.2, Kimi K2.7 and others, and ran them on the same evaluations. Then I measured what would happen if, for each problem, you somehow knew in advance which models would be useful and how their outputs should be combined. That hypo

GPT-5.5 Scores 10.6% on ActiveVision, Humans Hit 96.1% [R]

The interesting finding from a new [arXiv paper]( https://arxiv.org/abs/2607.16165 ) isn't that a frontier vision model failed a new benchmark, that happens weekly, but the specific shape of the failure and the fact that the models cannot patch it by writing their own code. The benchmark, called ActiveVision, contains 17 tasks across 3 categories designed, in the authors' words, to "force repeated visual perception rather than a single static description." GPT-5.5 at the highest exposed reasoning-effort tier solves 10.6% of items and scores zero on 11 of the 17 tasks. Claude Fable 5, which the authors note tops most reasoning and coding leaderboards, manages 3.5%. Three human participants averaged 96.1%. submitted by /u/Justgototheeffinmoon [link] [留言]

Claude’s voice mode is now available for Opus and Sonnet

Until now, voice mode has only been available on Claude Haiku, Anthropic's faster but less powerful model. Now the company is making its Opus and Sonnet models available in voice mode, and extending its reach into apps like Gmail, Slack, and Canva. When Anthropic launched voice mode earlier this year, it was primarily focused on […]
