Cognition cuts coding-model cost and makes repeated reviews incremental
Cognition’s SWE-2 Flash and Devin Review 2.0 reduce the advertised cost of everyday engineering work, while public model weights and independently verified review savings remain unavailable.
SWE-2 Flash launched November 4 in Devin Desktop and CLI.
Cognition advertises one-fifth SWE-2’s price and roughly three times its generation speed. The model is derived from Thinking Machines’ earlier Inkling-Small, with additional training; Cognition says it is developing controlled weight access for partners and researchers rather than publishing the weights now. The price and speed comparisons are vendor claims, not measured savings on a team’s completed work. [1][3]
Devin Review 2.0 followed on November 5. Repeated reviews normally focus on changes since the previous review, with full reassessment when the change requires it, rules for triggering reviews and a per-pull-request automatic-review spending limit. Manual reviews remain available after that limit is reached. Cognition reports an 82% reduction in review cost since August and a typical review costing US$0.25–$0.75. Its separate claim that roughly 80% of pull requests cost less than US$1 includes all pushes; those are different denominators. [2][4]

Images & figures
Devin normally reviews the changes since its previous pass and carries earlier findings forward. A large or substantially changed pull request can trigger a full reassessment.
