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.

SAME BENCHMARK RELEASE

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 Inkling · xhigh checkpoint is published by Thinking Machines for language and reasoning. Its weights are available under Apache 2.0; that alone does not establish that its code and all components are open source.

When to consider it

Compare Inkling · xhigh 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 740 GB from 975B stated parameters. It is not a measured minimum; context, batch size, runtime and quantization change actual memory use.

Run locally: known and unknown

~740 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.
