Ox Alpha

Anonymous 1M-context reasoning model available free through OpenRouter

Ox Alpha is a stealth AI model that appeared on OpenRouter and OpenCode on 20 August 2026. Its creator is unidentified, and OpenRouter routes requests to an anonymous third-party provider. The model accepts text, images and video, outputs text, and supports a 1,048,576-token context window with up to 131,072 tokens of output. OpenRouter lists it as a reasoning model for coding, sustained agentic work and production workloads.

WHY WE PICKED IT

The combination of a one-million-token context window, multimodal inputs, free pricing during the preview, and rapid adoption by coding-agent builders makes it worth tracking even before its creator is known. Within a day of launch, coding agents had pushed billions of tokens through it, suggesting real production interest rather than curiosity traffic.

STRENGTHS

LIMITATIONS

GETTING STARTED

Open the Ox Alpha page on OpenRouter, sign in, and try the playground, or call model ID `stealth/ox-alpha` through the OpenRouter API. OpenCode also offers it through its model catalog with the /models command. Use non-sensitive tasks first.

QUICK TIPS

1 Do not paste proprietary code, passwords, or personal data into an anonymous preview
2 Run the same task through a named frontier model for comparison
3 Test on small, representative coding tasks before larger agent runs
4 Watch OpenRouter and OpenCode for announcements about pricing and identity
5 Treat benchmark claims from small community tests as preliminary

USE CASE EXAMPLES

Probe a Long Coding Task

Use the large context window to analyse a mid-sized codebase or a long bug report in one session.

STEPS:
  1. Pick a non-sensitive repository or bug report
  2. Send the relevant files or trace as a single long context
  3. Ask for a root-cause analysis and patch plan
  4. Compare the output against Claude or GPT on the same task
  5. Note where the model stalls or loops without acting
