Questions

How is LLM API pricing quoted?

Per million tokens, with separate prices for input (the prompt) and output (the reply). This table lists each vendor's standard rate: batch processing, prompt caching and off-peak discounts lower it, and some vendors charge more above a context-length threshold, which the notes column names.

What is the price range across these models?

As listed on October 22, 2026, input prices in this table start at $0.075 per million tokens (openai/gpt-oss-20b) and output prices go up to $50.00 (Claude Fable 5.1). A lower list price says nothing about quality or speed, so compare on your own workload.

Are any of these prices about to change?

Yes. Google lists Gemini 4 Argon at this price through November 30, 2026; Google lists Gemini 3.8 Flash at this price through December 31, 2026. The notes column gives the price after that date.

Does upAPI sell LLM API access?

No. upAPI's public catalog is data and automation APIs (search, scraping, maps, social, developer tools); it does not resell model tokens. This table is a reference for the agents and apps that call both.
