Aion-3.0 and North Mini Code are available through the OpenRouter API, so switching between them takes a model slug change rather than a new integration.
Aion-3.0, from Aion Labs, has a 131,072-token context window and is priced at $3/M tokens input, $6/M tokens output on OpenRouter.
North Mini Code, from Cohere, has a 256,000-token context window and is priced by the provider serving it on OpenRouter.
