Code Models

Windsurf is an AI-native IDE built on VS Code by Codeium, featuring the Cascade agentic system for autonomous multi-file editing, terminal integration, and codebase-aware task execution. In 2026 it evolved into Devin Desktop, a unified command center for managing local and cloud-based coding agents. It supports multiple frontier models including Claude, GPT-5.4, and Codeium's proprietary SWE-1.5.

Devin Desktop (formerly Windsurf IDE, rebranded June 2, 2026) is an autonomous AI coding agent platform by Cognition AI. It functions as an 'Agent Command Center' with a Kanban-style interface for managing multiple parallel AI agents. Built on the proprietary SWE-1.6 model, it supports autonomous task delegation, multi-repo workflows, and the open Agent Client Protocol (ACP) for third-party agent integration.

Claude Code is Anthropic's agentic coding tool that operates within the terminal, IDEs (VS Code, JetBrains), and a dedicated desktop application. Generally released May 2025 and actively maintained through June 2026, it understands entire codebases, executes multi-file edits, manages git workflows, and supports sub-agent spawning (up to 5 levels deep) via natural language commands.

Kiro is an agentic AI coding platform from AWS that launched internationally on May 7, 2026, as the official successor to Amazon Q Developer. It introduces a 'spec-driven development' methodology requiring formal requirements, design, and task artifacts before code generation, using an SMT solver to mathematically verify specifications for logical contradictions. Built on Code OSS and integrated with Amazon Bedrock.

Kimi K2.7-Code is an open-weight coding-focused language model released by Moonshot AI on June 12, 2026, under a Modified MIT license. It is optimized for agentic coding workflows with 30% lower reasoning-token usage than its predecessor K2.6, and serves as the engine behind the Kimi Code terminal-first coding agent.
