grok-4 outperforms gpt-4.1 on 11 of 11 shared benchmarks. See the benchmark comparison above for specifics — grok-4 and gpt-4.1 have different strengths across reasoning, coding, math and multimodal tasks.
Which is cheaper — grok-4 or gpt-4.1?
gpt-4.1 is cheaper. grok-4 costs $3.00/$15.00 per 1M input/output tokens, while gpt-4.1 costs $2.00/$8.00.
Can I use grok-4 and gpt-4.1 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch — "xai/grok-4" or "openai/gpt-4.1" — no other code changes needed.
What are the context windows?
grok-4 supports up to 256K tokens of context. gpt-4.1 supports up to 1.0M tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
