Grok 4.5
Pricing & Specs
xAI · $2 input / $6 output per 1M tokens · 500K context window
The per-token price never tells the full story. A typical task (1K input + 500 output tokens) on Grok 4.5 costs about $0.0050 — roughly $5.00 per 1,000 runs. But if it needs 3x the tokens of a cheaper model to match quality on YOUR task, the economics flip. The only way to know is to benchmark it on your actual workload.
