Which is cheaper, claude-fable-5 or glm-5.2?
glm-5.2 is cheaper. claude-fable-5 costs $10.00/$50.00 per 1M input/output tokens, while glm-5.2 costs $1.40/$4.40.
Can I use claude-fable-5 and glm-5.2 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch between "anthropic/claude-fable-5" and "zai/glm-5.2", no other code changes needed.
What are the context windows?
claude-fable-5 supports up to 1M tokens of context. glm-5.2 supports up to 1M tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
