xAI launched Grok 4 in early 2026, and it quickly became one of the most capable reasoning models on the market. But with great capability comes significant cost. This guide breaks down every pricing tier, compares Grok 4 against competing models, and shows you how to cut your API bill substantially.
xAI offers several Grok 4 variants, each targeting different use cases and budgets:
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Context Window | Best For |
|---|---|---|---|---|
| Grok 4 | $3.00 | $15.00 | 256K | Complex reasoning, coding |
| Grok 4 Mini | $0.50 | $2.00 | 128K | Fast tasks, chat |
| Grok 4 Vision | $4.00 | $18.00 | 256K | Multimodal analysis |
These prices reflect xAI's direct API pricing as of April 2026. The flagship Grok 4 model sits in the premium tier, competing directly with OpenAI's GPT-5 and Anthropic's Claude Opus 4.6.
Here's how Grok 4 stacks up against the other frontier models in 2026:
| Model | Provider | Input (per 1M tokens) | Output (per 1M tokens) | Context |
