Questions people ask
Is deepseek-ai/DeepSeek-R1 better than glm-5.1?
Benchmark data is limited for one or both models. Compare pricing and capabilities in the tables above, and test both on your own workload.
Which is cheaper, deepseek-ai/DeepSeek-R1 or glm-5.1?
deepseek-ai/DeepSeek-R1 is cheaper. deepseek-ai/DeepSeek-R1 costs $0.85/$2.50 per 1M input/output tokens, while glm-5.1 costs $1.40/$4.40.
Can I use deepseek-ai/DeepSeek-R1 and glm-5.1 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch between "deepinfra/deepseek-ai/DeepSeek-R1" and "zai/glm-5.1", no other code changes needed.
What are the context windows?
deepseek-ai/DeepSeek-R1 supports up to 64K tokens of context. glm-5.1 supports up to 200K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
