Where it performs best

LiveBench 2026-06-25 · 0–100 ↗

LiveBench 2026-06-25 measures the named benchmark variant, not a local Q4 run. Scores were collected 2026-09-26; the seven categories share the same 0–100 scale. This is not the Artificial Analysis Intelligence Index. Q4 size covers only the counted weights; multimodal auxiliary components may add files.

Quality versus estimated Q4 weight size

Full ranking ↗

Reviewed language checkpoints with a LiveBench score and a parameter-based size estimate. The highlighted point is this model when both values are available.

Horizontal axis: estimated Q4 model-weight disk size in decimal GB (log scale). Vertical axis: LiveBench overall / 100. This formula is not the published checkpoint size, runtime memory or a speed test. Models without both inputs are left out of this chart, not scored as zero.

The Kimi K3 checkpoint is published by Moonshot AI for language and reasoning. Its weights are available under Kimi K3; that alone does not establish that its code and all components are open source.

When to consider it

Compare Kimi K3 with other language and reasoning checkpoints using its linked publisher card and the LiveBench 2026-06-25 snapshot. This is quality evidence, not a local speed result.

Check before choosing

The generic Q4 planning estimate is about 2108 GB from 2800B stated parameters. It is not a measured minimum; context, batch size, runtime and quantization change actual memory use.

Run locally: known and unknown

~2108 GB generic Q4 planning memory. Formula: parameters × 0.625 bytes, plus 20% working allowance and 8 GB reserve. This is neither measured VRAM nor checkpoint download size.

Q4 planning estimate only. Check checkpoint format, runtime support, KV cache, context, batch size and offload before choosing hardware.

Evidence level: Generic estimate only; no execution reproduced by this site.
