OpenRouter's Hunter Alpha, a cloaked 1 trillion parameter frontier model with 1M token context, has broken into the top 10 weekly usage rankings. Built for agentic use, it excels at long-horizon planning and complex multi-step reasoning.

OpenRouter, an AI model routing platform, released Hunter Alpha on March 11, 2026 — a stealth frontier intelligence model with 1 trillion parameters and a 1,048,576-token context window. Cloaked to gather community feedback before a full reveal, it's designed for agentic workflows: long-horizon planning, complex reasoning, and sustained multi-step task execution. The model has since cracked the platform's top 10 weekly usage charts.

Having a 1 million token context window at frontier-model scale gives AI agents the ability to reason over much larger codebases, documents, and task histories in a single session. This context depth makes Hunter Alpha well-suited for multi-agent orchestration frameworks that depend on sustained reasoning across extended execution chains.

Point your agentic workflows at openrouter/hunter-alpha to test how it handles long-horizon planning and complex multi-step task execution.
