THE CURRENT BALANCE OF POWER IN OPEN MODELS

The gap from open to closed models available to users has been decreasing over the last 3 years. Open model usage is exploding in high-value industries. Open-weight models have passed an inflection point in economic viability. Chinese labs are clearly maintaining their status as the leaders of the open-weight AI ecosystem.

SWARM SCALING

Scaling up the number of agents in a swarm by 10x doesn't get as much performance as using 10x as many tokens with one agent. This shortfall accumulates quickly for larger scale-ups, with the swarm falling further and further behind. However, swarms can theoretically achieve the same task in much less time as they are run in parallel. The speedup is substantial, so swarms are useful in situations where a large premium is paid for speed.

THE GREAT UNBUNDLING OF INTELLIGENCE

Agent economics are pushing AI from frontier-by-default toward capability-level routing, where judgment, ranking, search, and verification use cheaper specialized systems. Frontier models may handle fewer but harder tasks as applications become intelligence compilers that recombine services efficiently.

BRINGING DEVIN CLOUD TO YOUR TERMINAL

Developers can now create, steer, resume, and watch Devin Cloud sessions from their terminal. Devin CLI can now transfer any ask to Devin to continue iterating on with its own cloud VM. Users can continue to observe and steer progress directly from the terminal as if Devin were working locally. Cognition is offering free SWE-2 sessions until October 8 so developers can try Devin Cloud from the terminal.
