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 GPT-5 Mini
GPT-5 Mini is a mid-range large language model from openai, priced at $0.6/1M input tokens and $2.4/1M output tokens. It is 77% cheaper than the market average and best suited for cost-efficient frontier tasks. The 512k context window makes it suitable for very long documents, large codebases, and book-length inputs.
For most production workloads, the cost breakdown is dominated by input tokens (system prompts, context, retrieved documents) rather than output. At this price point, GPT-5 Mini is a solid choice when balancing quality and cost at scale.
GPT-5 Mini supports prompt caching at $0.3/1M — a 50% discount on repeated input tokens. For applications with a fixed system prompt or repeated document context (RAG, chatbots, agents), enabling caching is the single highest-leverage cost optimization available.
