Category rankings & sources

Each position belongs to a separate Arena category. These are human preference rankings—not hardware recommendations. We do not combine the categories into one score.

Rankings reflect the dated export; live Arena boards can change. Open-source positions use Arena’s open-model filter. The overall position also includes the other models on that category board. Availability of weights and license terms still need to be checked separately.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

Best for

Private, high-capacity reasoning on an 80 GB-class GPU or large unified-memory machine.
Structured output and local tool-use experiments.

Tradeoffs

A 65 GB download needs substantial extra runtime and context memory.
Published package fit is not a measured responsiveness result for your hardware.

Ways to run it

Ollama · Windows, macOS, Linux

Ollama lists a 65 GB package and says the large variant fits on a single 80 GB GPU. Usable context and speed still depend on the machine.
