Find the LLM API that's actually cheapest.

It depends on your token mix, but budget models like DeepSeek and Gemini Flash are typically the cheapest per token, while frontier models from OpenAI and Anthropic cost far more for the same tokens. Our calculator prices all 28 models at your exact volume and ranks them, or see the cheapest LLM API ranking.

From each model's official per-token input, output and cached price, verified by hand, at the request volume and token sizes you enter — the same engine across every page. We compute a monthly figure rather than quoting one, so models compare on the same workload. See the methodology.

No — each model family uses its own tokenizer, so the same text becomes a different number of tokens from one provider to the next (commonly a 10–30% spread). We compare list price per 1M tokens and run one identical workload through every model. Full methodology →

At high volume on a clear task, cost per call is cents while the human time it offsets is worth far more, so ROI is strong. For one-off or zero-error-tolerance work it often isn't. The ROI calculator shows net savings and break-even for your scenario.

No. The LLM section carries no affiliate links and no sponsored placement — rankings are by objective cost only. It exists to be an accurate, independent reference.
