| What is free | Preview ended on or about 2026-08-26, within a day of the predicted 2026-08-27. The model stealth/ox-alpha is no longer listed at all on openrouter.ai/api/v1/models (417 models returned, zero occurrences of the string "stealth"), and openrouter.ai/stealth/ox-alpha now states: “Ox Alpha was revealed to be ZAI GLM-5.3-Flash, which can be used here”. The successor is NOT free: z-ai/glm-5.3-flash on the same endpoint prices prompt at 0.000000075 and completion at 0.00000025 per token ($0.075 / $0.25 per M). Re-read 2026-09-08: that price still stands but is PROMOTIONAL — trade reporting describes a 50% launch discount ending 24:00 on 2026-09-09 (UTC+8), and the endpoint corroborates it, listing z-ai/glm-5.3-flash:batch at exactly double ($0.15 / $0.50 per M). Expect the headline rate to revert to $0.15 / $0.50 from 2026-09-10; the figures above are a dated snapshot of a discount, not a standing price. What this row used to claim, while it was true: $0 prompt and completion tokens on stealth/ox-alpha during a limited-time preview — a reasoning model aimed at coding and agentic work, 1,048,576-token context, 131,072 max output tokens, text + image + video input, which OpenCode described as “near unlimited” within OpenRouter's free-model rate limits. |
