How long does gemini-3.7-flash batch take at Google?

Measured, not promised. Google publishes a completion window of 24 hours and nothing more precise; below is what 10 real batch jobs actually did.

Every measured job, slowest last

Share of jobs finished, against elapsed time. 10 completions, 30-day window.

The curve is drawn from the pooled measurements, while the headline percentiles above are the median of each contributor's own figures - so the two need not line up exactly. That is deliberate: no single source can move a headline number by sending more data.

What you can plan for

24 hours

Provider's published window - not a measurement

Plan for 24 hours - and note where that number comes from. With 10 measurements there is no order statistic that can bound the upper end, so the honest planning number is Google's own published completion window. That is a contract they wrote, not something we observed.

For contrast, what we did observe: a p90 of 3 min across 10 jobs. Too thin to plan on, which is exactly why it is not the number above.

How much this answer is worth

Confidence: Very low

Score 0.19 · basis: exact_model

Limited by only 10 measurements, a single contributor, an upper bound we cannot pin down.

Pooled across all measurements: fewer than 3 contributors have enough data to vote, so a single contributor could move this number. Confidence is capped accordingly.

Where the numbers come from

Each measurement is one completed batch job. The duration is end minus start, both timestamped by our server - a client can never submit a duration, and a job we stopped waiting for is recorded as abandoned, never as a fast completion.

Timestamps are absolute and in UTC on purpose: this page may be cached, and a relative age would quietly go stale in the cache while an absolute one stays true.
