Which is cheaper, gpt-4.1 or grok-4.3?
grok-4.3 is cheaper. gpt-4.1 costs $2.00/$8.00 per 1M input/output tokens, while grok-4.3 costs $1.25/$2.50.
Can I use gpt-4.1 and grok-4.3 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-4.1" and "xai/grok-4.3", no other code changes needed.
What are the context windows?
gpt-4.1 supports up to 1.0M tokens of context. grok-4.3 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.
Switch between gpt-4.1 and grok-4.3 with one line of code
Requesty provides a single OpenAI-compatible API for 400+ models. Change the model parameter, not your code.
