Nova 2 Lite and Qwen3 Embedding 8B are available through the OpenRouter API, so switching between them takes a model slug change rather than a new integration.
Nova 2 Lite, from Amazon, has a 1,000,000-token context window and is priced at $0.30/M tokens input, $2.50/M tokens output on OpenRouter.
Qwen3 Embedding 8B, from Qwen, has a 32,768-token context window and is priced at $0.01/M tokens on OpenRouter.
