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

Reasoning score dominates at 75%. The quality floor is the strictest of any workload (65) because a weak reasoning model is not merely slower — it is confidently wrong. Latency is deliberately down-weighted to 0.3: reasoning models emit long thinking traces, so tokens/sec matters less than whether the conclusion is right.

Worked example — Gemma 4 27B ⭐: capability 94.4 × 0.44, quality 92.7 × 0.259, context 97.3 × 0.168, license 70 × 0.035, accessibility 80 × 0.097 + 6 tag bonus (reasoning, complex-tasks).

Requirements applied: context floor 16,384 tokens (ideal 131,072), quality floor 65, licence weight 0.3, latency weight 0.3.
