All but 2 of the top 30 contestants in the IMO 2025 math competition were of Asian or Eastern European ethnicity.

The hardest high school math exam in the world, the 6 problem 9 hour IMO 2025, was this week. AI models performed poorly. Gemini 2.5 Pro scored the highest, just 13/42, costing $431.97, in a best of 32 eval. Bronze cutoff was 19. Long way to go for AI to solve hard Math.

OpenAI dropped ChatGPT Agent today which uses your computer, and tools like Excel and Slides. It's far from the best... When tasked to build a 12-page slide deck for a FIRE (financial independence, retire early) plan, Genspark crushed it. We're still in early days of agents.

Perplexity is giving away Pro to 360M Indians for a year. If it doesn't work, at 1 query/day, it can cost them $700M-$3.6B/yr. If even 1% convert to Pro, it could mean $720M in ARR.

The rumor on Windsurf debacle is that everyone post-Google owned ~10% equity of the original co, but now had 100% with no pref stack / founder equity. Cognition supposedly paid ~$250M, implying the same ~$2.5B val Google paid. If true, everyone landed on their feet.

Most important tech blog this year: OpenAI engineer and ex-founder of $3.5B Segment wrote a tell all post about how OpenAI works internally. From obsession with X, devout use of Slack to engineering culture and tech stack. A peek under the hood of a generational company.

Google DeepMind just dropped this new LLM model architecture called Mixture-of-Recursions. It gets 2x inference speed, reduced training FLOPs and ~50% reduced KV cache memory. Really interesting read. Has potential to be a Transformers killer.

It’s crazy that the S&P 500 actually only returns 8% YoY in the last 5 years while 7 tech companies return 30%. Tech keeps the American Dream alive.

Grok just dropped Companions, animated AI characters that talk to you in realtime! There are 2 so far: — Ani, a sexual anime girl who wants to cuddle and — Bad Rudy, a mischievous fox that just wants to cuss you out. Judge for yourself, here’s a video:

The total value of all public companies in the tiny Bay Area (population 8M) is greater than India, Japan and Germany (population: ~1680M) combined. There’s a reason why it’s called the global hub of innovation.
