Frequently asked questions
Which AI model is the best for the lowest possible cost in 2026?
Right now we put BGE Reranker Base from cloudflare-ai-gateway at the top, primarily because its sum of input + output per-million-token cost is the lowest among models that are not placeholder-priced. Rankings are recomputed from live model metadata — see "How we picked these" above for the exact rule.
What is the cheapest option in this list?
BGE Reranker Base (cloudflare-ai-gateway) is the lowest-priced pick at $0.003 per 1M input tokens and Unknown per 1M output tokens. Costs from other entries scale up from there.
How are these rankings generated?
Each pick comes from a programmatic rule defined in our use-case-rules config: a hard filter (e.g. tool calling required, context ≥ 100K) plus a numeric score combining capability, context window and price. We never hand-curate the order, but we do hand-curate the rule. Underlying model metadata is refreshed daily from a normalised canonical catalogue.
How often is this page updated?
The underlying model data is refreshed once per day, and the static page is rebuilt when the data changes. The 'Last updated' date below shows the most recent rebuild.
Are 'Unknown' priced models excluded?
Yes. We only rank models with a published per-million-token price. 'Unknown' here means the provider does not publish a public rate card — it is not the same as 'free', so showing them at $0 would mislead.
