# Radiance model families

The selection key is the exact **(architecture id, quantisation descriptor)** pair, so a family at
two weight formats is two `.so` files. A checkpoint's id is its `config.json` `model_type` without
underscores (`qwen3_5` → `qwen35`); `rad-convert --arch ID` overrides it. `data/recipes/` is the
authority: **read the recipe's header** — it names the exact `rad-convert` line, its `--set` keys
and whether it needs calibration.

## The plugin table

## Recipes of record, by family

`$SRC` is a downloaded checkpoint; `$CALIB` is a calibration directory (see
[[Radiance Conversion]]). Paths are shortened to the recipe name.

| Gemma 4 31B Q8 grid | `gemma4-31b-dense-bf16-q8-df.recipe` |
| Gemma 4 26B-A4B + DFlash | `gemma4-26b-a4b-df.recipe`; `-pad768` when the experts were padded to 768 (down may then be block fp8) |

| MiniCPM5-2B | `minicpm5-2b-dspark.recipe` (or `-bf16-dspark`) with `--draft-model $DSPARK` |
| Qwen3.6-35B-A3B | `q36-35b-a3b-fp8.recipe` |
| Qwen-Image 2.1 | `qwen-image-2.1-fp8.recipe` (Turbo uses the same file) or `-bf16` |
| Krea 2 | `krea-2-fp8.recipe`, `krea-2-bf16.recipe`, `krea-2-fp8-unscaled.recipe` for a plain-FP8 finetune file |
| FLUX.3 [klein] | `flux-3-klein-fp8.recipe` |
| SDXL / finetunes | `sdxl-bf16.recipe --tokenizer <openai/clip-vit-large-patch14>/tokenizer.json` |

| nomic-embed-v2-moe | `nomic-embed-v2-moe-bf16.recipe` |
| Unlimited-OCR | `unlimited-ocr-bf16.recipe` |
| Qwen3-ASR | no container: serve the checkpoint directory as it ships |
| EmbeddingGemma 2, Nemotron Embed/Rerank | serve the checkpoint, or convert bf16 with no recipe |

A checkpoint served at its own precision needs no container at all:
`radiance --model /srv/models/hf/Qwen/Qwen3.8-27B-FP8`. Convert when you want a tier only a container
has (quantised encodings, a drafter, a second vocab) or a smaller file.

## Family-specific traps

- **`head_dim` is read, never derived.** On the Qwen hybrids it is 256 while `hidden_size /
  num_attention_heads` is 213; a derived value silently breaks projection widths, KV page size and the
  attention kernel's band.
- **A fused projection shards by part, not by contiguous rows.** A tensor-parallel rank owns a slice
  of *each* stacked projection in a fused `[gate|up]` or `[q|k|v|z]`; a contiguous slice would hand
  rank 0 the whole gate, and the model would produce fluent wrong text. This is declared through
  `RadWeightDecl::row_parts`, never inferred from the container.
- **Gemma 4 26B-A4B:** the routed experts' `gate_up` may be block fp8, but `down` stays bf16 unless the
  experts were padded to 768 — hence the `-pad768` recipe.
- **GLM-5.3-Flash:** every weight is served as stored except the latent attention's small `kv_b`,
  decoded to bf16. Its KV cache is bf16 only (the plugin refuses `fp8` at startup), and at 172 GiB it
  needs `--tp 8`.
- **TranslateGemma 27B:** the checkpoint's template takes structured turns naming two languages and
  refuses the plain turn the server renders at startup. The container therefore serves a plain Gemma 3
  template, and a client sends on `/v1/completions` the prompt the checkpoint's own template renders.
- **ParoQuant containers made before 1.5.0 are refused at startup.** Convert again with the old
  container as `--reuse`; every tensor that did not change is copied.
- **SDXL carries no tokeniser.** Pass CLIP's `tokenizer.json` beside the single file. A Krea 2
  finetune shipped as one DiT file in Krea's key names is rewritten into a directory whose
  `transformer/` holds it (`scripts/krea2_native.py`), with the release's other parts copied in.
- **Anima** ships as three single files: `--add` the text encoder and VAE, `--config` a Qwen3-0.6B-Base
  directory (config + tokenizer), `--tokenizer2` ComfyUI's T5 tokenizer, `--arch anima`,
  `--set anima.variant=…`.
- **drama-3's codec is `codec.pth`**, a `torch.save` file read as data, never unpickled.
- **Generators that load LoRA files declare their module aliases**; the checkpoint and a ComfyUI port
  disagree in ways that load without error and generate garbage. The per-plugin alias table is in
  `docs/ARCHITECTURES.md` ("Adapter key names of the generators").
- **Licences travel with the checkpoint, not the engine.** Qwen-Image 2.1 is non-commercial;
  MiniMax-H3's licence excludes the EU, UK, Republic of Korea and USA; drama-3's community licence
  needs a commercial licence to serve speech to others, and cloning a real person needs consent;
  Breeze-TTS-2 is research/non-commercial.
