Questions people ask

Is deepseek-v4-pro better than glm-5.2?
deepseek-v4-pro and glm-5.2 trade wins evenly across shared benchmarks. See the benchmark comparison above for specifics: deepseek-v4-pro and glm-5.2 have different strengths across reasoning, coding, math and multimodal tasks.
Which is cheaper, deepseek-v4-pro or glm-5.2?
deepseek-v4-pro is cheaper. deepseek-v4-pro costs $1.74/$3.48 per 1M input/output tokens, while glm-5.2 costs $1.40/$4.40.
Can I use deepseek-v4-pro 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 "fireworks/deepseek-v4-pro" and "zai/glm-5.2", no other code changes needed.
What are the context windows?
deepseek-v4-pro 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.
