Instructions to use sfanm/d24-v6.2-1 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use sfanm/d24-v6.2-1 with Transformers:

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

pipe = pipeline("text-generation", model="sfanm/d24-v6.2-1")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("sfanm/d24-v6.2-1")
model = AutoModelForCausalLM.from_pretrained("sfanm/d24-v6.2-1", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	--data '{
		"model": "sfanm/d24-v6.2-1",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/sfanm/d24-v6.2-1

D24 v6.2-1

Public preservation release for the full branch of the D24 v6.2 ratio-20 experiment. This repository contains both the terminal midtraining state and its terminal SFT descendant.

Repository layout

Repository root: final SFT Transformers model (BF16, SimpleChatML).
midtrain-hf/: final midtraining Transformers model (BF16 base model).
megatron-midtrain/iter_0004226/: exact terminal Megatron checkpoint, including optimizer/training state.
megatron-midtrain/: trackers, completion receipt, and frozen config.
provenance/: frozen campaign tickets and SFT receipt/config.

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "sfanm/d24-v6.2-1"
sft_model = AutoModelForCausalLM.from_pretrained(repo, token=True)
sft_tokenizer = AutoTokenizer.from_pretrained(repo, token=True)

midtrain_model = AutoModelForCausalLM.from_pretrained(
    repo, subfolder="midtrain-hf", token=True
)

Lineage

Stage	Source/final state
Pretraining	iteration 84,527; 354,530,270,862 tokens
Midtraining	iteration 4,226; 17,725,128,704 tokens
SFT	iteration 1,773; 475,114,114 packed tokens

Historical midtraining used the experiment's branch-scaled WSD schedule: warmup_iters=177 and decay_iters=845 with cosine decay. SFT used a constant learning rate of 1e-4 from optimizer step zero with zero warmup.

Both portable exports contain 756,819,456 parameters in BF16. This repository is an artifact-preservation release with frozen lineage and integrity metadata.
