Which is cheaper — gpt-5.1 or deepseek-r1?
deepseek-r1 is cheaper. gpt-5.1 costs $1.25/$10.00 per 1M input/output tokens, while deepseek-r1 costs $4.00/$4.00.
Can I use gpt-5.1 and deepseek-r1 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch — "openai/gpt-5.1" or "novita/deepseek/deepseek-r1" — no other code changes needed.
What are the context windows?
gpt-5.1 supports up to 400K tokens of context. deepseek-r1 supports up to 64K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
