🎬 Ox Alpha: The Mystery AI That Just Tore Down the Coding Leaderboard

A 30-second tech short from the NXagents dev-workshop — the story of Ox Alpha, the anonymous model that appeared on OpenRouter on Aug 20 and scored an eye-watering ~80% on the DeepSWE coding benchmark, leaving the big names in the dust:

Model	DeepSWE score
Ox Alpha (stealth)	~80%
Claude Fable 5	65%
GLM-5.3	62%
Grok 4.6	62%
GPT-5.6-sol	52%

Why everyone's talking about it

• Anonymous + free: stealth/ox-alpha dropped onto OpenRouter with a 1,048,576-token context window and text/image/video input — free for one week.
• Who's behind it? Community forensic work — tokenizer probes, a video-encoder token-for-token match, and an Aug 22 serving-layer Java stack trace — all point to a hidden Zhipu AI GLM-5.x variant served via Z.AI. Officially? Nobody's confirmed a thing.
• The pattern: Pony, Hunter, Elephant, and Owl Alpha — every prior stealth model traced back to a Chinese lab. This one looks like the same playbook.
• Caveat: that 80% came from a community 10-task run by developer Ben Davis, not an official leaderboard. Still, the numbers turned heads.

Developer takeaway

The free window ends ~Aug 27. If you build with coding agents, grab it on OpenRouter and throw a SWE-bench task at it while it's free — worst case you lose a few tokens, best case you're early on the next frontier model.
