+
+A mobile-friendly bundle of **Chroma1-HD** (8.9B Flux-derived DiT) packaged with T5-XXL + Flux VAE, sized for on-device inference via [**Mirage**](https://github.com/haplollc/Mirage).
+
+Chroma1-HD is the high-resolution flagship variant from [lodestones/Chroma1-HD](https://huggingface.co/lodestones/Chroma1-HD) — fully open weights built on FLUX.1's architecture with significant retraining for general-purpose generation. Excellent at photorealism, illustration, and concept work.

+## What's inside
+
+| File | Role | Size |
+|---|---|---|
+| [`Chroma1-HD-Q4_K_S.gguf`](./Chroma1-HD-Q4_K_S.gguf) | Diffusion transformer — Flux-arch, 8.9B params, Q4_K_S | 5.1 GB |
+| [`t5xxl_fp16.safetensors`](./t5xxl_fp16.safetensors) | Text encoder (T5-XXL, fp16) | 9.1 GB |
+| [`ae.safetensors`](./ae.safetensors) | VAE (from FLUX.1) | 320 MB |
+
+Total bundle: **~14.5 GB**. Total GPU residency: ~15-16 GB. **iPhone 17 Pro / Air (12 GB) or M-series Mac required.** Older iPhones cannot hold this model.
+
+## Quick start (Mirage)
+
+```swift
+import Mirage
+
+let docs = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
+
+let engine = try Engine(models: ModelFiles(
+    diffusionModel: docs.appendingPathComponent("Chroma1-HD-Q4_K_S.gguf"),
+    vae:            docs.appendingPathComponent("ae.safetensors"),
+    textEncoder:    docs.appendingPathComponent("t5xxl_fp16.safetensors")
+))
+
+let image = try await engine.generate(.init(
+    prompt: "a Hopper-style oil painting of an empty diner at dawn, soft warm light",
+    width: 1024, height: 1024,
+    steps: 28,
+    cfgScale: 4.0    // Chroma's recommended CFG
+))
+```

+| Component | Upstream | License |
+|---|---|---|
+| Diffusion transformer | [lodestones/Chroma1-HD](https://huggingface.co/lodestones/Chroma1-HD) | Apache 2.0 |
+| GGUF conversion | [silveroxides/Chroma1-HD-GGUF](https://huggingface.co/silveroxides/Chroma1-HD-GGUF) | Apache 2.0 |
+| Text encoder | [comfyanonymous/flux_text_encoders](https://huggingface.co/comfyanonymous/flux_text_encoders) (`t5xxl_fp16.safetensors`) | Apache 2.0 |

+
+## Sizing
+
+- **iPhone 17 Pro / Air (12 GB RAM)** — works but tight; expect ~8 min per 1024² image.
+- **iPhone 16 Pro (8 GB RAM)** — does NOT fit. The text encoder alone is 9 GB. Use [`Z-Image-Turbo-iOS`](https://huggingface.co/jc-builds/Z-Image-Turbo-iOS) instead.
+- **M2 / M3 Mac** — comfortable, ~4-6 min per 1024² image at 28 steps.
