if you value intelligence above all other human qualities, you’re gonna have a bad time

I’ll be in seoul this week, any cool ICML parties I should go to?

@stevenyfeng @AnthropicAI Congrats!

Looks like @ashVaswani’s Essential AI was acquihired, as per their Head of Talent’s LinkedIn.

Is this news or am I late to the party?

@aryagm01 @TanejaPriyal cool!

I have not joined Anthropic

@GavinSherry @Sonos Most physical smart home devices need better software. I buy for APIs instead of UIs now

[Evergreen Capital @evergreencap3]

Following-up: Muse Spark is 100% legit. It handles my general queries as well as, if not better than, other frontier models. And echoing @borrowed_ideas: 'contemplating mode' is a true leading-edge feature.

Congrats to @alexandr_wang and the entire MSL team! Can't wait for more.

Wow. Claude Mythos represents at 20% jump on SWE-bench Pro over the next best model, GPT-5.4

Congrats to the @AnthropicAI team!

@Nottlespike @AnthropicAI Interesting. Haven’t read the technical report in full yet, will have to do some poking around

@adonis_singh 🔥

Very excited for you all to see Muse Spark! It’s a capable model that excels in multimodal and agentic tool use tasks.

Spark is the first (of many) steps towards Personal Superintelligence, and I look forward to seeing how our models evolve as we get closer to that goal :)

[Alexandr Wang @alexandr_wang]

1/ today we're releasing muse spark, the first model from MSL. nine months ago we rebuilt our ai stack from scratch. new infrastructure, new architecture, new data pipelines. muse spark is the result of that work, and now it powers meta ai. 🧵
