As recorded at collection: OpenRouter Ox Alpha, 1 week of free API access

Ox Alpha Free is an AI model that appeared on OpenCode and OpenRouter on August 20, with no provider disclosed. It is free for one week, supports a 1M-token context, the amount of input it can process at once, and outputs of up to 131K tokens. It supports text, image, and video input, three reasoning levels, max, high, and low, tool calls, and JSON output. It is described as the only free model that can process video input.

In OpenCode, update the program and select Ox Alpha Free from the /models menu. For the OpenRouter API, prepare an API key, the authentication string required to use the service, set the request URL to https://openrouter.ai/api/v1/chat/completions, and set the model name to stealth/ox-alpha. Send the Authorization: Bearer $OPENROUTER_API_KEY authentication header as well.

The weighted average price is $0. Free usage has been officially announced as nearly unlimited, but there have been cases of speed limits on the first day. OpenCode says it does not retain data. OpenRouter's detailed terms say that providers retain prompts and responses but do not use them for training, while Stealth's terms of service include a clause allowing user content to be used for training and improvement. The publisher recommends using it only for public projects and test code, and not entering API keys or company code.
