Frequently asked questions
Which AI model is cheapest for production use?
For high-volume workloads, GPT-5 Nano, Gemini 2.5 Flash-Lite and Mistral Small 3 are the cheapest options at under $0.10/1M input tokens. For mid-tier quality with good throughput, Gemini 2.5 Flash and Claude Haiku 4.5 offer excellent value. Paste your real prompt above to get exact monthly cost estimates for your volume.
Is GPT-5 worth the cost compared to Claude 4?
GPT-5 and Claude Sonnet 4.6 are in similar price tiers for complex tasks. GPT-5 tends to be cheaper for input-heavy workloads; Sonnet 4.6 is often better value for coding and multi-step reasoning. Claude Opus 4.7 is significantly more expensive but targets the most demanding agent and research workloads. Run your specific prompt through the comparison tool for exact numbers at your volume.
How much cheaper is Gemini 2.5 Flash vs Gemini 2.5 Pro?
Gemini 2.5 Flash is roughly 8× cheaper than Pro for typical workloads. Flash-Lite is even cheaper — about 12× less than Pro. For most production use cases, Flash offers near-Pro quality at a fraction of the cost. Flash-Lite is best for simple classification or retrieval tasks at very high volume.
Should I choose a more expensive model or optimize my prompts?
Often both. A well-optimized prompt on a cheaper model can outperform a bloated prompt on a premium model — both in cost and sometimes quality. Use our Prompt optimizer to see how much you can save by tightening your prompt, then compare the optimized prompt across models here.
