Claude Haiku 4.5 and GLM 4.7 are available through the OpenRouter API, so switching between them takes a model slug change rather than a new integration.
Claude Haiku 4.5, from Anthropic, has a 200,000-token context window and is priced at $1/M tokens input, $5/M tokens output on OpenRouter.
GLM 4.7, from Z.ai, has a 204,800-token context window and is priced at $0.40/M tokens input, $1.75/M tokens output on OpenRouter.
