About

SWE-2 is Cognition’s advanced coding model designed to improve software engineering performance while reducing the cost of agentic coding workflows. The model is post-trained from Kimi K3 and uses reinforcement learning to optimize multiple reasoning-effort levels within a single training run. SWE-2 is designed to explore codebases more selectively, begin implementation sooner, and complete tasks with fewer redundant reads and reasoning steps than earlier Cognition models. Its capabilities include code generation, debugging, test creation, verification, repository analysis, and complex terminal-based software engineering tasks. The model also emphasizes stronger engineering judgment, end-to-end test coverage, instruction following, and evidence-based verification of user assumptions. SWE-2 is available through Devin Desktop and Devin CLI, with broader rollout planned across Devin Web and Fusion.

About

siift is an AI-native strategy and operations platform designed to help people build businesses with more clarity, confidence, and leverage. It combines proven entrepreneurship and innovation processes with a master context system, evidence-based guidance, and a visual business canvas that keeps ideas, assumptions, actions, results, and metrics connected. It works across five modes, Ideate, Validate, Build, Go To Market, and Scale. Users can explore multiple opportunities in parallel, identify blind spots, compare ideas against the same evidence standard, turn assumptions into structured research and experiments, connect validated customer value to MVP and product strategy, refine positioning and channel experiments, and identify constraints limiting growth. siift scores the strength of evidence behind claims so decisions can be based on signals rather than confidence or AI-generated encouragement.

Pros & Cons from Real Users

Pros

  • The biggest thing that stands out is the cost-performance balance. SWE-2 is not just trying to top one benchmark; it is trying to get very close to frontier coding performance at a much lower cost. For developers, that matters a lot. Coding agents can burn through tokens quickly when they are reading files, making edits, running tests, and iterating. A model that performs near the top while being meaningfully cheaper is much easier to use every day. I also like that SWE-2 seems built for real software engineering workflows, not just isolated code snippets. The strong DeepSWE and Terminal-Bench results make it especially interesting for repo-level tasks, debugging, tool use, and longer agent runs.

Cons

  • Benchmarks are useful, but real projects bring messy architecture, flaky tests, undocumented behavior, and weird edge cases.
