What is SWE-2?

SWE-2 is Cognition’s coding model for software engineering agents, developed to improve the balance between capability, reasoning cost, and execution efficiency. The model is post-trained from Kimi K3, a multi-trillion-parameter model that had already received extensive reinforcement learning for agentic coding. Cognition further trained SWE-2 with a reinforcement learning algorithm that optimizes several reasoning-effort levels during a single training run. These effort levels let users trade off speed and cost against deeper planning, codebase exploration, and verification for more difficult assignments. SWE-2 is designed to reduce the over-exploration seen in earlier models by identifying relevant files and implementation paths more quickly. Its software engineering abilities include repository analysis, code writing and editing, debugging, testing, build and lint workflows, terminal tasks, and verification of completed work. The model places additional emphasis on writing end-to-end tests, catching edge cases and regressions, and gathering evidence instead of simply accepting assumptions in a prompt. Cognition’s training approach also uses cost penalties tied to the model’s performance frontier, length-weighted reward baselines, speculative decoding improvements, low-precision inference techniques, and expanded reinforcement learning data. Training data includes more diverse repositories, additional instruction-following requirements, and iterative verifier improvements designed to reduce reward hacking and false validation. SWE-2 is benchmarked against models such as GPT-6 Astra, GPT-5.6 Sol, Fable 5.1, Grok 4.6, and Kimi K3, with Cognition positioning it around strong coding performance at substantially lower cost. SWE-2 is intended for use across Cognition’s Devin ecosystem, including Desktop and CLI, with rollout to Devin Web and Fusion.

What is ChipAgents?

ChipAgents is an innovative platform that revolutionizes agent-based AI chip design and verification by embedding intelligent AI agents into the electronic design automation workflows, allowing hardware engineers to efficiently create and validate semiconductor designs with greater reliability and less manual effort. By leveraging advanced generative and agent-driven AI technologies, ChipAgents can understand design specifications and transform natural language or documents in PDF form into RTL (Register-Transfer Level) code, automatically complete Verilog/SystemVerilog code, generate testbenches, analyze simulation outcomes, and detect bugs within large codebases, which significantly accelerates verification cycles and reduces time-to-market. The agents within ChipAgents function seamlessly alongside the existing code editors or EDA processes utilized by engineers, automating routine tasks such as coverage gap analysis, waveform debugging, functional verification, and diagnosing failed tests. By organizing design logic, logs, and waveform data into coherent insights, these agents alleviate teams from tedious manual responsibilities, thereby boosting overall productivity. Furthermore, this cutting-edge methodology not only simplifies the design workflow but also promotes enhanced collaboration among team members, ultimately leading to superior results in semiconductor development and innovation. As a result, ChipAgents represents a transformative leap forward in the field of electronic design automation.
