ChatGPT-5 API Pricing: Cost Models, Budgets, and Optimization
June 29, 2025•7 min read•FromYou AI Team
How Pricing Typically Works
Pricing is usually per 1K input/output tokens with model-specific rates and throughput caps. You control spend with token budgets, model choice, and prompt design. Below are practical strategies to keep quality high while costs stay predictable.
Budgeting Strategies
- • Cap tokens per route and implement auto-summarization for long histories.
- • Choose the lowest capable model; escalate only when needed.
- • Cache frequently requested results and reuse embeddings.
- • Batch requests for bulk generation tasks.
Prompt and Context Optimization
- • Keep system prompts concise and task-specific.
- • Truncate or vector-retrieve only the relevant context.
- • Prefer structured outputs to reduce re-tries.
