How to use ShellFace/20260819-040753 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ShellFace/20260819-040753")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("ShellFace/20260819-040753")
model = AutoModelForMultimodalLM.from_pretrained("ShellFace/20260819-040753", device_map="auto")

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },

	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

R861 — SoftCtx × MidRank × MidBeta UltraLoLR (offline DPO on vera king)

Affine SN120 challenger for Reason v4 (weight_version_key=7): tempered multi-sample log-mean-exp over k=3 teacher refs (τ=0.03).

Per turn: a_i = lpC(y_i|z_A) − lpC(y_i|∅); Reason = τ·log(mean_i exp(a_i/τ)). Crown also needs median stripped |z|≥80 and B pass ≥0.30.

How this checkpoint was trained

Base / parent: vera6/affine-5g4yy75zuz-t6@8e3f1695e058837ed80fec3238ff439fdc2d0f0e (live king reign36)
Method: offline DPO on Reason-ranked duel pairs (not SFT / not online GRPO)
What was optimized: preference for thoughts that raise teacher-side Reason (commit to a teacher next-action mode; filler loses under LME)
Data: Soft Mid Mid Soft × SoftCtx filtered duel preference pairs from dpo_duel_reason.jsonl under mining/experiments/r861-vera-offline-dpo-hialpha-midrank-midbeta-softctx-megasuperextrasteps-ep4-ultralolr / pod /root/r861/ (~259–604 rows at launch)
Key hyperparameters:
- LoRA r=32 (MidRank), α=128 (HiAlpha)
- β=0.1 (MidBeta)
- lr=5e-7 (UltraLoLR)
- max_len=12288 (SoftCtx)
- max_steps=19200 (MegaSuperExtra)
- epochs=4
Hardware: Lium mine-crown-1 (gentle-orbit-bd) 8×B200 GPUs 4,5 train+merge+challenger serve + v4 n80 → /tmp/r861_merged (~66G / 16 safetensor shards; weight_identical=false)
Local n80 vs live king reign36 (vera6/affine-5g4yy75zuz-t6@8e3f1695e058837ed80fec3238ff439fdc2d0f0e) under wvk=7:
- margin +0.003665, SE 0.001684, z=2.177, n=80
- bar max(2·SE, δ=0.002) = 0.003367 (~1.088×)
- thought median 141.5 (≥80 ✓), B pass 0.5375 (≥0.30 ✓)
- k=3, τ=0.03 (fail-closed if stamp ≠ v4)
- decision: WIN / Stage-5 licensed (r861_decision_reign36_wvk7.json, p3966)
