Best pick for your memory budget

The strongest model overall is rarely the right answer — what matters is the strongest model that fits the memory you have. These picks are re-ranked per tier, so each one uses its budget rather than simply being small.

How this ranking works

The lowest quality floor in the set (40) and the strongest tag weighting toward small, low-memory models. Offline use is constrained by the hardware you happen to have with you, so a model that runs on 8 GB and never stalls beats a stronger model that needs a desktop.

Worked example — Ternary Bonsai 27B: capability 88.6 × 0.389, quality 87.7 × 0.229, context 100 × 0.149, license 70 × 0.062, accessibility 80 × 0.172 + 6 tag bonus (laptop, on-device).

Requirements applied: context floor 8,192 tokens (ideal 65,536), quality floor 40, licence weight 0.6, latency weight 0.7.
