Why compare LLM API pricing?
Frontier-quality models are increasingly available through multiple providers and routing layers at very different rates. Two models with similar benchmark scores can differ by 10x or more in per-token price, and output tokens usually cost several times more than input tokens. For chat products, agents, and batch pipelines, that gap compounds fast at scale.
How the estimate works
Monthly cost equals requests times average input tokens times the input rate, plus requests times average output tokens times the output rate, with rates expressed per one million tokens. Adjust the sliders to match your real traffic pattern: retrieval-heavy apps skew toward input tokens, while long-form generation skews toward output tokens.
Tips to cut spend without downgrading quality
Route routine traffic to efficient models and reserve premium models for hard requests. Use prompt caching for repeated system prompts, trim context windows, cap max output tokens, and batch offline workloads where discounted tiers exist.
