Qwen3.7 Max and Nemotron 3 Nano Omni are available through the OpenRouter API, so switching between them takes a model slug change rather than a new integration.
Qwen3.7 Max, from Qwen, has a 1,000,000-token context window and is priced at $1.475/M tokens input, $4.425/M tokens output on OpenRouter.
Nemotron 3 Nano Omni, from Nvidia, has a 256,000-token context window and is priced by the provider serving it on OpenRouter.
