This series is still computed and served here, but a newer definition replaced it; it is not listed and not indexed. See the current series.
The Frontier token input floor (legacy) is USD 1.32 per 1M input tokens on 2026-10-24 (n=8), set by llm/deepseek/deepseek-v4-pro. Definition: Lowest input price (USD per 1M tokens) among the current flagship chat models of the first-party labs (constituents listed in the detail), as published by LiteLLM. Legacy series, kept for existing links and stored history; superseded by the launch series.
Computed from the SKU state at the end of each UTC day (latest value: 2026-10-24; today's value is recomputed until the day ends). The constituents of the latest value are listed below; each shows when it was verified and links to its source.
Change over this window: +203.4% from 2026-07-27 to 2026-10-24 (level).
Dashed lines with a diamond mark days on which the set of constituents (n) changed; a jump on such a day can be coverage, not a price move.

A model that is in the list but not (yet) in the data simply does not contribute; n shows how many did. Until first-party price pages are parsed, these prices come from LiteLLM, a community cross-check.
