Notes

Gemini 3.1 Flash Lite Preview released March 3, 2026. Cheapest Google model at $0.25 input / $1.50 output per 1M tokens. Best for high-volume, cost-sensitive workloads (classification, simple generation, retrieval-augmented tasks). Superseded Gemini 2.5 Flash Lite. [2026-08-24] Verification attempt produced no clear result — recheck next run. Sources conflict: pricepertoken.com and OpenRouter still list $0.25 input / $1.50 output, while the same aggregator reports Google AI Studio at $0.125 input / $0.750 output and claims the cheapest input price has fallen 50% over ~90 days. No official ai.google.dev confirmation of a cut surfaced in search snippets. Prices LEFT UNCHANGED at $0.25 / $1.50 pending a primary source. If confirmed, this is a 50% cut on both sides. [2026-09-21] Verification attempt produced no clear result — recheck next run. The same two-sided split persists, now in its second flagged run and essentially unchanged in character: a dedicated search returned "$0.125 per million input tokens and $0.750 per million output tokens" alongside "the cheapest Gemini 3.1 Flash-Lite is at $0.25/$1.50", with the search itself attributing the gap to sources updating at different times or to platform differences (AI Studio vs third-party providers). The provider-wide Gemini search this run covered 3.1 Pro, 3.5 Flash and 3.7 Flash but did not quote Flash Lite at all, so it neither confirmed nor refuted either figure. Prices LEFT UNCHANGED at $0.25 / $1.50. ACTION FOR KHALED: ai.google.dev/gemini-api/docs/pricing is the row's own Pricing Page URL and would settle this in one look — if it reads $0.125 / $0.75, this is a 50% cut on both sides and the calculator is currently overstating the cheapest Google tier by 2x. Note the contrast with Gemini 3.7 Flash, where the intro-vs-standard split IS cleanly documented; the Flash Lite ambiguity looks like an unannounced AI Studio rate rather than a published promotion. [2026-10-08] SETTLED by the provider page https://ai.google.dev/gemini-api/docs/pricing: standard $0.25 input (text/image/video; audio $0.50) / $1.50 output, batch $0.125 / $0.75 — the $0.125/$0.75 figures are the BATCH rate, not a cut. Cache Read filled: $0.025 (text/image/video). Prices unchanged.
