xAI: Grok 3

Grok 3 is a workhorse model for enterprise-style tasks: pulling data from messy text, writing code, and turning long material into usable summaries. Cost-wise, it sits in the middle at $3/$15 per 1M tokens, but real usage is often cheaper than people expect: a long PDF plus questions is about $0.32, and even a 50-step agent workflow is around $0.53. The non-obvious part is that its strongest value is not chatty creativity, but repeatable output you can plug into actual systems.

Best for

  • Extracting structured data from documents, emails, and other messy business text.
  • Coding tasks where you need usable completions at a predictable per-task cost.
  • Summarizing long reports or PDFs and then asking follow-up questions on them.

Not ideal for

  • People hunting for the absolute lowest API price for high-volume generation.
  • Use cases where you mainly want a personality-first consumer chatbot experience.
