Local Models

Field notes from local models actually in use. What the measurements say, what the instrument got wrong, and which layer was carrying the result.

Nothing here ranks a model until the instrument that measured it has been checked.

The measured field

Personal benchmarking on hardware I actually use, published with the configuration attached. Each page carries its own date and moves when the numbers move.

When one card is not enough

Measured 28-29 Sep 2026 on two RTX 3090s in a headless test bench, one card against both. Most of the roster fits one 24 GB card and gains nothing from a second. Two models do not fit, and they behave differently.

ModelSizeOne cardTwo cards
qwen3-next (80B MoE)50 GB46% in VRAM, 25.6 tok/s92-96% in VRAM, 72.6 tok/s
nemotron-3.5-lightning (30B MoE)25.4 GB87.5% in VRAM, 49-58 tok/s100% in VRAM, 75-88 tok/s

qwen3-next needs both cards. On one it runs at about a third of the speed with more than half the model on the CPU. nemotron-3.5-lightning is borderline: its weights nearly fit one card, but with its context and working memory about an eighth spills to the CPU. It still runs there at roughly two-thirds of its two-card speed, and holds that speed as context fills (75 tok/s at 115k tokens on two cards).

On the same five repair tasks, with every sampling parameter pinned identical, nemotron-3.5-lightning, qwen3-next Instruct and qwen3.6:35b scored 30, 27 and 29 of 30. At six trials per task that is a tie, not a ranking. Where they differ is wall clock: 8.6, 25.0 and 5.7 minutes for the thirty cells.

qwen3-next Thinking, run as designed with reasoning on (32k context, temperature 0.6), scored 29 of 30 with no timeouts, in 69.6 minutes. It is reported on its own because its settings differ from the three above.

Earlier qwen3-next results on this site used the Thinking variant run in non-thinking mode. They describe that configuration, not the model.

When the instrument was wrong

Two pages about measurement rather than models. Both exist because a number looked like a finding and was not.

The layer underneath

Do not ask only which model is strongest. Ask which layer is carrying the result: grounding, routing, protocol discipline, repair policy, role fit, or raw model power.

The framework material that used to sit on this page has its own home now, because it is not about local models.
