# 4-bit Browser Gallery Models

This artifact is less glamorous than the model work, but it is exactly the kind of public detail users care about: what ships, how big it is, and what tradeoff it makes.

- gallery
- quantization
- browser

## Headline Numbers

Evidence class applies to each value: measured = retained evaluation or runtime result; historical = recorded result not freshly reproduced; derived = calculated or decided from records; observed = current artifact state; not-measured = an explicit evidence gap.

Gallery download

 ~75MB -> ~20MB 4-bit storage-side variants observed

Compression

 ~4x int4 gallery files vs fp16 derived

Browser-loadable

 yes unlike Mac-side multi-GB specialists observed

## Competitive Context

**System**

**Metric**

**Score**

**Size / Class**

**Comparable?**

**Readout**

 posttrainllm int4 gallery file download size ~20MB 4-bit storage Direct Smaller cold-load distribution artifact for browser demos.

 posttrainllm fp16 gallery file download size ~75MB fp16 storage Direct Simpler baseline with larger download size.

 Mac specialist packages artifact size multi-GB HF/MLX safetensors Directional Different distribution lane; browser gallery compression should not be mixed with Mac specialist packaging.

Direct rows share this artifact's eval setup. Directional rows are useful market context but should not be read as leaderboard claims.

## Distribution tradeoff

**Format**

**Benefit**

**Limit**

 fp16 Simple and accurate Larger download

 int4 storage Smaller cold load Not a training-speed win

## Release Blockers

### Not the active artifact channel

Browser gallery models are not the same as Mac-side specialist packages.

 Unblock: Keep separate from specialist registry; only connect through public reports.

- [Gallery manifest](https://posttrainllm.com/gallery/manifest.json)

## Next Release Action

Keep as a public distribution artifact and avoid mixing it with Mac specialist packaging claims.
