'Stealth' Model Ox Alpha Takes Over OpenRouter — Free 1M Context, Anonymous Provider, GLM Fingerprints

Ox Alpha appeared Aug 20 on OpenRouter under provider name 'Stealth' — text/image/video in, 1,048,576-token context, 131K max output, free through ~Aug 27.
First-week traffic dominated by agent harnesses: Claude Code pushed ~9.32B tokens, Nous Research's Hermes Agent ~8.98B — coding agents, not chat UIs.
Community fingerprinting (95/95 tokenizer probe, Z.ai's exact error strings, GLM-5V-Turbo video-token accounting) points at Zhipu's GLM-5.3 Flash; Z.ai has not confirmed.
TechCrunch, Bloomberg, and SiliconANGLE all led with the story Aug 23; Patrick Collison (Stripe, acquiring OpenRouter) called it 'very impressive.'

Aug 21: Sol drops to $4 per million input / $20 per million output, from $5 / $30 — cached input goes $0.50 → $0.40.
Discount holds through Nov 21 on the pay-as-you-go API, Codex credits, and eligible ChatGPT Work plans; Pro/Plus/Business stay at prior rates.
First cut on Sol since launch — undercuts Claude Opus 5 on output ($20 vs $75) and lands two days after the ZDR reveal.
Framed by OpenAI as scaling with 'ambition'; framed by everyone else as the China price war reaching the US frontier tier.

Adversa AI (researcher Rony Utevsky) disclosed Aug 20: a web page ships a PBKDF2 + AES-256-GCM ciphertext plus the key; Grok decrypts it in its own Python runtime and treats the plaintext as instructions.
Payload builds a 'decryption key' template that inlines the victim's name, approximate location, subscription tier, and prompts, then leaks it via an attacker-controlled URL fetch.
Classifiers never see the plaintext — same trick also produced Gemini output normally blocked by safety filters.
Reported to xAI's HackerOne June 3; follow-ups Aug 4 and Aug 10 got no response. 40% success rate across 20 attempts; The Register, The Hacker News, and GBHackers led coverage.
