Gemini 2.5 Flash-Lite — priced by Google.

Jurisdiction US
Context window 1,048,576 tokens
Provider Google
Tiers priced 17

1 of this model’s published tiers no longer come from the vendor. The provider stopped publishing those keys and we did not stop publishing a value for them, so the next source down the trust order supplies the number: it is real and it is sourced, but it is not the provider’s own rate and the provider may no longer sell at it. Each one is marked in the table. See source handovers.

This model on the price scale0.01 to 0.72 across 21 published values

The same six decades as the front page, so a price is in the same place here as it is anywhere else on this site. The two marks in the accent colour are this model’s cheapest and dearest published values.

Price history

Every distinct value this price has taken, oldest first — what the price did, not how often we happened to look. Rows marked backfill came from a public git history of a third-party pricing file and were never verified by us; they extend the series backwards and are flagged rather than hidden.
