3 new signals we're tracking
1. xAI's Colossus 2 aims to surpass rivals with a gigawatt-scale datacenter and unique RL methodology
inference-infrastructure, ai-products - production, business - June 26, 2026
What changed? xAI is still squarely in the frontier-AI race and is positioned to leapfrog most rivals again on compute. By our estimates, its total datacenter capacity for a single training cluster will surpass Meta Superintelligence and Anthropic by Q3 2025.

Why is this signal important? This matters because frontier labs are turning datacenter scale into a model-capability advantage.
2. A general-purpose AI model has solved a major open problem in mathematics
model-releases - research, release - May 26, 2026
What changed? a general-purpose model solved a major open problem in mathematics. we'll be saying this a lot over the coming years, but this is a kinda big milestone.

Why is this signal important? This matters because new benchmark gains can change which models builders choose for coding and reasoning work.
Vibe Check — what the community is buzzing about
Sourced from public engagement on Reddit, Hacker News, and GitHub over the last 30 days — not from our tracked authors. Loud, not (yet) authoritative.
1. Share your AGENTS.md file

Why is this signal important? This matters because public community momentum can reveal what builders are testing, questioning, or adopting before it becomes an authoritative signal.
2. Anyone else find their CLAUDE.md / AGENTS.md files end up lying to the agent after a few months?
