GPT-3.5 Turbo Frequently Asked Questions (FAQ)
Key insights into GPT-3.5 Turbo API pricing, context capacity, caching savings, and performance benchmarks
Q. What is the API pricing for GPT-3.5 Turbo? How much does it cost per 1M tokens?＋
GPT-3.5 Turbo (OpenAI) is priced at $0.5000 per 1 million input tokens and $1.5000 per 1 million output tokens. The output rate is approximately 3.0x higher than the input rate. You can simulate your exact monthly API expenses tailored to your request volume and token length using the calculator above.
Q. What are the context window and maximum output limits of GPT-3.5 Turbo?＋
GPT-3.5 Turbo features a 16K context window and a maximum output limit of 4K tokens per request. It provides sufficient capacity for standard chat interactions and structured data processing.
Q. What are the best practices for optimizing API costs with GPT-3.5 Turbo?＋
Because output tokens ($1.5000/1M) cost significantly more than inputs, always configure a strict max_tokens ceiling and employ structured output schemas. Additionally, pairing GPT-3.5 Turbo with lightweight models for routine tasks via multi-LLM routing can substantially lower total infrastructure spend.
Q. What is the benchmark score (47.5) and performance profile of GPT-3.5 Turbo?＋
GPT-3.5 Turbo achieves an overall benchmark score of 47.5/100 with a "Fast" speed rating. It is optimized for high-throughput, low-latency applications requiring budget-conscious performance.
Q. Which alternative models are comparable to GPT-3.5 Turbo?＋
Key alternatives in similar price-to-performance tiers include GPT-5 mini, grok-code-fast-1, Gemini 3.1 Flash-Lite Preview. We recommend comparing them based on your latency targets, context window needs, and prompt caching benefits using the full comparison tool on this site.
