Agentation

Kilo Code is an open-source AI coding agent for VS Code, JetBrains, and CLI that generates code from natural language, automates complex tasks, and runs terminal commands. It supports 500+ AI models at provider rates and features an Orchestrator mode that breaks complex tasks into coordinated subtasks across planner, coder, and reviewer agents. With 1.5M+ users and 25T+ tokens processed, it's the #1 coding agent on OpenRouter.

Cursor Composer 2 is an advanced agentic coding model built into the Cursor IDE, released March 19, 2026. With a 200,000-token context window, it autonomously plans and executes complex, multi-file coding tasks across an entire codebase — handling file edits, terminal operations, and tool use at frontier-level performance. It is used by over 50,000 businesses including Stripe.

GStack is an open-source Claude Code workflow system created by Y Combinator CEO Garry Tan, designed to encode specialized AI roles for planning, code review, QA, and shipping. Built with Bun and Playwright, it uses route-aware QA and structured release workflows to connect code changes with actual application behavior. Enables developers to achieve 10,000+ lines of quality code per week.

Amp is an agentic coding platform that combines a powerful code review agent, composable extensions, and a unique 'oracle' reasoning layer powered by GPT-5.4 for complex analysis tasks. It offers a free ad-supported tier alongside paid smart plans, with the code review agent now composable and extensible for team workflows. Amp is one of the fastest-growing AI coding tools of early 2026.

Anthropic is agentic coding assistant that lives in your terminal. It understands your codebase, edits files, runs commands, and helps you code faster through natural language commands.

Gemma 4 is Google DeepMind's most capable open-source AI model family, released in April 2026 under the Apache 2.0 license. It features Dense and Mixture-of-Experts (MoE) architectures in four sizes (E2B, E4B, 26B, and 31B), purpose-built for advanced reasoning, coding, and agentic workflows. The E2B and E4B variants are specifically optimized for on-device inference on smartphones and edge hardware like Raspberry Pi, with deep collaboration from Qualcomm and MediaTek.
