xAI released Grok 4.7, claiming enhanced self-verification and extended context handling. The model is priced at $2 per million input tokens and $6 per million output tokens.

Grok 4.7 targets developers and knowledge workers with upgrades focused on reasoning accuracy and longer document processing. The company positions the model as twice as fast as comparable alternatives at half the cost. The new version emphasizes self-verification capabilities, allowing the AI to check its own outputs for accuracy. Extended context management enables processing of longer documents and code files, addressing a key limitation in previous versions. Pricing undercuts major competitors. Input tokens cost $2 per million, while output tokens run $6 per million. This positions Grok 4.7 competitively against Claude and GPT-4 for cost-conscious users. The release targets the coding and knowledge work segment, where reasoning quality directly impacts output value. Performance improvements in these areas could drive adoption among professional users who require both speed and accuracy.
