GPT-4.1 vs Grok 4.3
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
GPT-4.1
OpenAI · Apr 2025
A non-reasoning workhorse with a 1M-token context window, still popular for predictable-latency production APIs.
Grok 4.3
xAI · Apr 2026
xAI's frontier model: 1M context at $1.25/$2.50, ~168 tokens/sec, and a record low hallucination rate on independent testing.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Grok 4.3 is about 2.2x cheaper per blended million tokens (3:1 input:output mix).
