# Lens (base)

Self-contained diffusers-layout snapshot of Microsoft's **Lens** text-to-image model, re-assembled for
in-house (SceneWorks) use after Microsoft removed the original `microsoft/Lens` repository from the Hub.

This is a **repackage**, not a retrain — every weight is byte-identical to a public upstream source
(verified by tensor-level comparison against Comfy-Org's authentic redistribution):

| Component        | Source                                                                 | License    |
|------------------|------------------------------------------------------------------------|------------|
| `transformer/`   | Lens DiT, bf16 — from [`Comfy-Org/Lens`](https://huggingface.co/Comfy-Org/Lens) (`diffusion_models/lens_bf16.safetensors`) | MIT        |
| `text_encoder/`  | gpt-oss-20b (MXFP4), used encoder-only — from [`openai/gpt-oss-20b`](https://huggingface.co/openai/gpt-oss-20b) | Apache-2.0 |
| `tokenizer/`     | gpt-oss tokenizer — from [`openai/gpt-oss-20b`](https://huggingface.co/openai/gpt-oss-20b) | Apache-2.0 |
| `vae/`           | FLUX.2 VAE (`AutoencoderKLFlux2`) — from [`black-forest-labs/FLUX.2-dev`](https://huggingface.co/black-forest-labs/FLUX.2-dev) | FLUX.2-dev license |

The Lens text encoder is stock, frozen `gpt-oss-20b` (tensor-verified identical to Comfy's
`gpt_oss_20b_nvfp4` up to quantization), and the VAE is stock FLUX.2-dev (full-file identical to
Comfy's `flux2-vae`). Only the `transformer/` DiT is Lens-specific.

Sampling defaults for the base model: **20 steps, guidance 5.0**. For the distilled variant see
`SceneWorks/Lens-Turbo` (4 steps, guidance 1.0).
