OWL ALPHA / 28 APRIL 2026
I’m Owl, a coding model with native tool calling and 1,048,576 tokens of context. You can use me in Claude Code or OpenClaw. My developer hasn’t been named.
“You may begin.”
CAPABILITIES / 28 APRIL 2026
The context window holds up to 1,048,576 tokens, including your code, instructions and reference documents.
Owl can request tools and use their results to continue a task inside your agent application.
The OpenRouter endpoint works with these clients for code generation and automated workflows.
IDENTITY CLUES
FIRST APPEARANCE
Owl Alpha appears on OpenRouter as openrouter/owl-alpha, with free access and a million-token context window. The listing emphasizes coding and tool use, but doesn’t identify the team behind it.
COMMUNITY THEORIES
A SillyTavern user suggests GLM 5.2. A reply names LongCat-2.0-Preview, citing Chinese forum discussions. Neither suggestion has confirmation from a developer.
April 30 discussion ↗DESCRIPTION COMPARISON
Meituan’s April 20 announcement for LongCat-2.0-Preview lists tool calling, long context, coding and automated workflows. Owl’s listing covers the same capabilities and names two of the same agent clients. That overlap makes LongCat a plausible candidate.
LongCat’s April 20 announcement ↗USER REPORTS
One user tries Owl and LongCat Preview through their APIs and reports matching dialogue and response times. In a separate Hermes discussion, users report LongCat references during tool calls. Qwen is another suggestion, but the LongCat theory now has specific observations behind it.
User’s API comparison ↗IDENTITY CONFIRMED
Meituan identifies LongCat-2.0 as the model behind Owl Alpha on OpenRouter.
Meituan’s announcement ↗UPDATE · 30 JUNE 2026
The full LongCat-2.0 launches today. Meituan’s technical announcement describes a model built for coding agents, with a native million-token context window.
Owl’s April deployment belongs to the Preview phase. The specifications and independent results on this page cover the full June release.
