Agents
SoonLong-horizon tool use without context collapse
What we learned from running coding agents for 1,000+ turns: the surprising failure mode isn't reasoning, it's memory shape.
Forthcoming
cosmicstack
Engineering the next
layer of intelligence.
Cosmic Stack is a research and product lab building the agents, infrastructure, and tools of the next decade.

research
A research lab with a product surface.
We publish what we learn, ship what we publish, and treat the gap between the two as the most interesting problem in applied AI.
Infrastructure
SoonEdge-native inference and the cost of cold paths
Where Workers AI wins, where it doesn't, and the architectural patterns that survive a 100× traffic spike at 3am.
Forthcoming
Evaluation
SoonWhy agent benchmarks lie — and what to measure instead
Most agent leaderboards measure the wrong thing. A practitioner's framework for evals that correlate with production reliability.
Forthcoming
products
Tools shipped from the research surface.
Each product is a real-world stress test of a research direction — and an independent business in its own right.
platform
Four surfaces, one stack.
Cosmic Stack operates as a research lab, an incubator, an open-source org, and an inference cloud — wired together by the same runtime and the same conviction.
