Model overview
LiteRT is Google's on-device runtime, the new name for TensorFlow Lite (Android: `com.google.ai.edge.litert:litert`), and `litert-torch`, the renamed `ai-edge-torch`, is its PyTorch converter: a PyTorch model converted unmodified with `litert_torch.convert` matched the original to 4e-7 on a Galaxy S26 (measured, LiteRT 2.2.0, Android 16, 2026-09-05). Black Forest Labs **[FLUX.2 [klein] 4B](https://huggingface.co/black-forest-labs/FLUX.2-klein-4B)** (Apache-2.0) converted to **LiteRT `CompiledModel`** int8 graphs, generating **and editing** images fully on a phone GPU. The upstream model card says klein "runs on consumer GPUs, with as little as 13 GB VRAM". These graphs run it on a Pixel 8a's Mali-G715, which has no dedicated VRAM at all. Prompt: *"a red apple on a wooden table, studio lighting"*. 4 steps, 256×256, generated end-to-end on a Pixel 8a Mali GPU in 306 s. Matches the fp32 `diffusers` pipeline at **PSNR 36.8 dB / corr 0.9987**.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
