Frequently asked questions
What is the cheapest LLM API right now?
BGE Reranker Base is the lowest-priced AI APIs on this list, at $0.003 per 1M input tokens and Unknown per 1M output tokens. The total column above sums input + output per 1M tokens for direct comparison.
Why are prices shown per 1M tokens?
Almost every commercial LLM provider publishes rates per million tokens. Per-1K-tokens or per-token rates are easy to misread (off by 1000×). Standardising on $/1M lets you compare vendors directly.
Are these prices including or excluding tax?
All prices are the provider's headline list rate in USD, before any volume discounts, prepaid credits, batch-API discounts, prompt-caching discounts or jurisdictional sales tax. Always verify with the provider before committing to a budget.
How often do these prices change?
Vendor list-price moves are typically picked up within hours of an announcement, and our pipeline re-syncs daily. Each change is also written to /changelog so you can audit historical pricing over time.
Why are some models showing 'Unknown' instead of a price?
We deliberately do not coerce missing data to $0. 'Unknown' means the provider does not publish a public rate (often models behind enterprise sales or invite-only access). Treating Unknown as free would push paid-but-unpriced models to the top of every cheap list — broken UX and broken SEO.
