Oh this looks very good
Today we're launching Executor v2 It's a massive overhaul to the product, finally unlocking every use case people have wanted from the beginning You can think of v2 as if Zapier / Retool were fully drivable as code, with everything being exposed to your agent

Inter but make it bouba
Hi @rsmsโ€” My background is in business systems, but Interโ€™s clarity inspired me to build Collab Sansโ€”an open-source rounded derivativeโ€”SIL OFL. Thanks for giving the world Inter! Iโ€™d be honored if you took a look: yugal.one/collab-sans

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a personโ€ฆfull of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

HOLY CRAP. Bloomberg has the goods on Gemini 4! "it does less well when employees actually put it to work .. The model struggles to handle certain coding tasks" Bloomberg: "As Alphabet Inc.โ€™s Google prepares for the coming launch of Gemini 4, itโ€™s grappling with internal skepticism over how well the flagship artificial intelligence model performs in key areas, such as coding. While Gemini 4 has performed well on benchmarks the industry uses to gauge model efficacy, it does less well when employees actually put it to work, according to people with direct access to the effort. The model struggles to handle certain coding tasks, said the people, who requested anonymity to discuss an internal matter."

Claude Opus 5.5 has the best visual design of any model I have tested so far

Donโ€™t see that too often
Replying to @ArtificialAnlys
Both models regress in GDPval-AA v2.1 at max effort, driven by shorter deliverables that more often omit required elements.
