Price from Google: the cheapest offer that is serving, at standard delivery and at the maker’s precision or better, at its standard rate.
Cheaper right now: $0.425/M at Google AI Studio — delivery tier (flex) It does not pass the like-for-like test, so it never sets a rank.

Our take
editorial — not a measurementFor an existing Gemini deployment, measure whether migration improves completed-task quality and cost. The accepted record distinguishes audio input from text-token pricing, so an audio-heavy estimate must use the relevant billing dimension. Check current benchmark evidence rather than assuming a newer model is better on every task.
Strengths
- Audio, video, image, file and text input are listed
- The accepted pricing record distinguishes audio input
Weaknesses
- A text-only token estimate can misprice audio workloads
- Cache retention and delivery mode need explicit assumptions
Reach for it when
- Migration evaluations for existing Gemini applications
- Multimodal workloads with measured input composition
Avoid it if
- Your estimate treats every input modality as text
- Another model has demonstrated a better result on your tasks

The verdict as one SVG, for a README or a docs page. It states this model's dominance status at the balanced workload on the LMArena lens, with the date it was computed, and it is rebuilt with the catalogue — so it changes when the verdict changes, including to one you would rather it did not.
