# How to Use
|
|
|
|
Lens uses a Lens diffusion transformer, the FLUX.2 VAE, and GPT-OSS-20B as the LLM text encoder.

|
|
Lens and Lens Turbo require an external GPT-OSS `tokenizer.json` matching the text encoder checkpoint. Save it as `tokenizer_gpt_oss.json` and pass it with `--tokenizer`; the tokenizer is not embedded in sd.cpp. See [JSON tokenizers](tokenizers.md) for CLI and C API usage.
