Which is cheaper, gpt-5.2 or deepseek-v3.2?
deepseek-v3.2 is cheaper. gpt-5.2 costs $1.75/$14.00 per 1M input/output tokens, while deepseek-v3.2 costs $0.56/$1.68.
Can I use gpt-5.2 and deepseek-v3.2 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch between "openai/gpt-5.2" and "vertex/deepseek-v3.2", no other code changes needed.
What are the context windows?
gpt-5.2 supports up to 400K tokens of context. deepseek-v3.2 supports up to 164K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
