usefulHQ Study · 2026
The same month of AI costs $0.2215 on DeepSeek vs $40 on Claude Opus, a 181× spread
We priced a typical assistant workload, 5 million input and 1 million output tokens a month, across the flagship models using live OpenRouter rates. The cheapest capable option, DeepSeek Flash Latest, runs about $0.2215 a month; the priciest, Claude Opus 5.5, about $40. For most tasks a mid-tier model does the job at a fraction of the frontier price, so matching the model to the task, not defaulting to the biggest name, is where the savings are.

How we rank. We cost your actual workload: input tokens × the input rate plus output tokens × the output rate. That matters because output usually costs 3-6× more than input so a model that looks cheap on input can be dear if you generate a lot. "Blended /1M" assumes a typical 3:1 input:output mix for a quick single-number comparison. All rates are standard USD per million tokens, converted live to your currency, batch APIs are ~50% cheaper and prompt caching can cut cached input up to 90%. Prices move fast; confirm on the provider's site.
Common questions
What's the cheapest LLM API?
Proprietary: Gemini Flash-Lite and GPT-4.1 Nano near $0.10/1M input. Cheapest overall is DeepSeek (~$0.14 in / $0.28 out). The best pick depends on your input:output ratio, use the calculator.
Why do input and output cost different amounts?
Generating output is far more expensive than reading input, so output is usually 3-6× the input price. That's why a single blended price is misleading.
Is Claude or GPT cheaper?
Close at the frontier. Claude Opus ~$5/$25, GPT-5 ~$2.50/$15 standard (much more for Pro). Claude's prompt caching can cut input up to 90%, often making it cheaper in practice.
How do I cut LLM costs?
Use a smaller model where you can (budget models are 20-50× cheaper), cache repeated prompts, use the batch API for non-urgent jobs, and trim prompt and output length.
The other way to pay for tokens
Per-million-token pricing only makes sense against the alternative, which is buying the hardware once and running the model yourself. These track what that hardware costs.
