Nova 2 Lite and bge-m3 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.
bge-m3, from baai, has a 8,194-token context window and is priced at $0.01/M tokens on OpenRouter.
