How are Intelligence, Speed & Cost bucketed?
Intelligence and Speed buckets are percentile ranks on
Artificial Analysis. Cost buckets are fixed dollar
thresholds keyed off output-token price ($/M out).

Percentile boundaries are computed across every model in the tree that reports the underlying benchmark for each capability.
What it feels like
- Four sizes (1B / 4B / 12B / 27B) — covers laptop-class up to single-GPU server inference
- Gemma-3-4B-IT beats Gemma-2-27B-IT; Gemma-3-27B-IT beats Gemini 1.5 Pro on shared benchmarks
- Vision input from 4B up; 1B is text-only — first Gemma family with multimodal at small sizes
Best use cases
- Single-GPU production inference (27B fits H100 / A100 80GB at FP precision)
- Laptop / phone deployment via the 1B / 4B variants
- Multilingual apps in 140 languages at open-weights pricing
Tools to try
Not ideal for
- Frontier reasoning leaderboards — Gemini 2.5 / 3 Pro and competitors lead
- Workloads needing 1M+ context (Gemma 3 caps at 128K)
