How this is calculated
Providers bill input and output tokens separately, per million tokens (MTok). Cached input tokens — a repeated prompt prefix the provider recognizes — are billed at a discounted rate.
cost = (input_tokens − cached_tokens) × input_rate
+ cached_tokens × cached_rate
+ output_tokens × output_ratePricing is verified against provider pricing pages as of 2026-09-01. AI and cloud pricing changes frequently — confirm the current rate on the provider's own pricing page before budgeting.
Frequently asked questions
Which LLM is cheapest?
It depends entirely on your token mix and required quality. Budget-tier models (GPT-5.6 Luna, Gemini Flash-Lite, Claude Haiku) are cheapest per token, but a flagship model may finish a task in fewer, more accurate turns — making it cheaper per completed task.
Should I compare cost per token or cost per task?
Cost per token is easy to compare but misleading on its own. A cheaper model that needs retries or produces longer, less useful output can cost more per completed task than a pricier, more capable one.
Do all providers price input and output tokens the same way?
The mechanism is the same — separate per-token rates for input and output, usually with a cached-input discount — but the actual rates vary widely by provider and model tier, which is what this comparison table shows.
How often does LLM pricing change?
Frequently — new model releases, price cuts, and tiered rates for long-context requests are common. This calculator is checked against provider pricing pages, but always verify before committing to a large-scale budget.
