Tips to reduce cost

  • Use prompt caching to reuse repeated system prompts
  • Trim whitespace and reduce verbose instructions
  • Use a smaller model for classification or routing tasks
  • Batch async requests to get 50% discount (OpenAI/Anthropic)
  • Cache identical requests at the application layer

About Grok 3 Mini

Grok 3 Mini is a mid-range large language model from xai, priced at $0.3/1M input tokens and $0.5/1M output tokens. It is 89% cheaper than the market average and best suited for fast cost-sensitive tasks. The 128k context window handles long documents, extended conversations, and large code files comfortably.

For most production workloads, the cost breakdown is dominated by input tokens (system prompts, context, retrieved documents) rather than output. At this price point, Grok 3 Mini is a solid choice when balancing quality and cost at scale.
