Dots3-Note Preview and GPT-5.6 Luna Pro are available through the OpenRouter API, so switching between them takes a model slug change rather than a new integration.
Dots3-Note Preview, from Dots Studio, has a 512,000-token context window and is priced by the provider serving it on OpenRouter.
GPT-5.6 Luna Pro, from OpenAI, has a 1,050,000-token context window and is priced at $0.10/M tokens input, $0.60/M tokens output on OpenRouter.
