# Grok 4.6

SpaceXAI, released 2026-08-07

**Verdict: conditional.** Grok 4.6 is SpaceXAI's frontier model for coding and agentic work at $2 input and $6 output per 1M tokens under 200K, with a 500K-token context; prompts of 200K or more bill at $4/$12. At launch it scored 61 on the Artificial Analysis Intelligence Index, tying GPT-5.6 Sol, but that is still one independent evaluator. Grok 4.7 now lists at the same price, so compare the two before committing new work. Last verified 2026-07-29.

## Pricing

- Input: $2.00 / 1M tokens
- Output: $6.00 / 1M tokens
- Context: 500K ctx; 200K+ $4/$12; cache $0.50

## Strengths

- Low-cost frontier-class calls at $2 input and $6 output per 1M tokens under 200K, cached input $0.50
- Coding, agentic tasks and knowledge work with text and image input over a 500,000-token context
- Tuning depth per call with reasoning effort low, medium, high or xhigh (default high)
- Trained alongside Cursor IDE data for strong repository-scale coding and agentic task performance
- Prompts of 200K tokens or more budgeted off the headline rate: input, cached input and output double to $4, $1 and $12 per 1M
- Batch workloads: the Batch API is not supported
- Workloads that need more than 500K tokens of context
- Deployments that must run in an EU region: xAI lists us-east-1, us-west-2 and us-central-1 only
