Questions people ask
Is deepseek-r1 better than gpt-5.1?
gpt-5.1 outperforms deepseek-r1 on 8 of 8 shared benchmarks. See the benchmark comparison above for specifics — deepseek-r1 and gpt-5.1 have different strengths across reasoning, coding, math and multimodal tasks.
Which is cheaper — deepseek-r1 or gpt-5.1?
deepseek-r1 is cheaper. deepseek-r1 costs $4.00/$4.00 per 1M input/output tokens, while gpt-5.1 costs $1.25/$10.00.
Can I use deepseek-r1 and gpt-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 — "novita/deepseek/deepseek-r1" or "openai/gpt-5.1" — no other code changes needed.
What are the context windows?
deepseek-r1 supports up to 64K tokens of context. gpt-5.1 supports up to 400K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
