Frequently Asked Questions
How much does GPT-5 cost per token?
GPT-5 costs $1.25 per 1M input tokens and $10.00 per 1M output tokens. For a typical conversation with 500 input tokens and 200 output tokens, that's about $0.0026 per request. GPT-5 mini is much cheaper at $0.25/$2.00 per 1M tokens.
How much does GPT-5 cost per month?
For 100K requests/month with 500 input + 200 output tokens each, GPT-5 costs approximately $250/month. GPT-5 mini costs ~$50/month for the same workload. Budget alternatives like Gemini Flash can reduce this to ~$15/month for simple tasks.
Is there a cheaper alternative to GPT-5?
Yes, several alternatives are significantly cheaper: DeepSeek V4 Pro ($0.44/$0.87) is 65% cheaper. Mistral Small 4 ($0.10/$0.30) is 92% cheaper. Gemini 3.1 Pro ($2.00/$12.00) is comparable quality at similar price. For simple tasks, Gemini Flash ($0.50/$3.00) costs 75% less.
How does GPT-5 pricing compare to Claude and Gemini?
GPT-5 ($1.25/$10.00) is mid-range. Claude Opus 4.8 ($5.00/$25.00) is 4x more expensive on input. Claude Sonnet 4.6 ($3.00/$15.00) is 2.4x more expensive. Gemini 3.1 Pro ($2.00/$12.00) is 1.6x more expensive. Budget models like GPT-5 mini ($0.25/$2.00) are 5x cheaper than GPT-5.
Can I reduce GPT-5 costs without switching providers?
Yes! Strategies include: (1) Use GPT-5 mini for simple tasks — 80% cheaper, (2) Optimize prompts to reduce input tokens, (3) Set max_tokens limits on responses, (4) Cache common queries, (5) Batch requests where possible. These can reduce costs by 30-50% even staying on GPT-5.
