Description

Nex-N2-Pro is an innovative open-source agentic model designed to enhance productivity in real-world scenarios by transforming reasoning into actionable, verifiable, and repeatable tasks. Instead of viewing reasoning, tool utilization, and environmental execution as distinct functions, Nex-N2 integrates these elements within a cohesive framework that aligns requirement comprehension, task organization, code execution, environmental feedback, assessment, debugging, and ongoing refinement into a seamless, closed-loop process. Its unified thinking approach spans searching, programming, and calling agentic tools, adhering to a consistent pattern of breaking down goals, tracking states, adjusting strategies, and performing self-assessments, which proves particularly advantageous in complex workflows that involve both coding and tool interactions. The model's Adaptive Thinking capability allows it to autonomously determine when to engage in deeper thought processes, enabling it to carry out straightforward actions swiftly while dedicating more time to critical decisions for optimal resource management, thus maximizing efficiency. This multifaceted approach ensures that Nex-N2-Pro is well-equipped to tackle a diverse range of tasks in dynamic environments.

Description

SWE-2 Flash is a high-speed AI software engineering model developed by Cognition for automated coding, development workflows, and technical problem-solving. The model is based on Inkling-Small from Thinking Machines and uses a mixture-of-experts architecture containing 276 billion total parameters and 12 billion active parameters. Cognition applies large-scale mid-training and reinforcement learning to improve the model's programming accuracy, reasoning capabilities, and ability to complete complex software engineering tasks. SWE-2 Flash supports code generation, repository maintenance, automated code reviews, feature implementation, documentation updates, and agent-driven software development. Its optimized architecture delivers approximately 200 tokens per second, making it three times faster than SWE-2 while operating at one-fifth the inference cost. The model achieved a score of 24.0% on FrontierCode 2.0, 45.5% on FrontierCode 1.1 Main, and 89.2% on Terminal-Bench 2.1 in Cognition's published evaluations. Training improvements also target general reasoning, problem-solving, and cybersecurity tasks to expand the range of activities supported by autonomous coding agents. SWE-2 Flash is available in Devin Desktop and CLI, allowing developers to incorporate the model into interactive and automated software engineering workflows. Cognition is also developing a controlled model-weight access program for trusted industry partners and researchers interested in fine-tuning, infrastructure control, and deployment in sensitive environments.
