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

pipe = pipeline("text-generation", model="AlephFunk/Qwen3-0.6B-Base-del12")
messages = [

pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("AlephFunk/Qwen3-0.6B-Base-del12")
model = AutoModelForCausalLM.from_pretrained("AlephFunk/Qwen3-0.6B-Base-del12", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,

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

outputs = model.generate(**inputs, max_new_tokens=256)

Qwen3-0.6B-Base-del12

Qwen3-0.6B-Base with decoder layer 12 deleted (28 -> 27 layers). Smallest proxy for fast iteration.

This is a research artifact, not a recovered model. It is a base (pretrained) Qwen3 model with decoder layers removed and no healing / fine-tuning of any kind. Its language-modelling loss and especially its state-tracking and multi-step-reasoning ability are degraded relative to Qwen/Qwen3-0.6B-Base; it is intended as a starting point for recovery experiments (e.g. recurrent replacement of the removed span).

Parent: Qwen/Qwen3-0.6B-Base (a base checkpoint; no instruct/post-trained weights were used).
Deleted original layers: [12].
Surviving layers are bit-identical to the parent's (renumbered), except where a collapsed group is listed (then: last layer's attention/MLP weights, base layer's norms).
Standard Qwen3 architecture: AutoModelForCausalLM.from_pretrained("AlephFunk/Qwen3-0.6B-Base-del12"). config.json has the corrected num_hidden_layers and layer_types.
Exact recipe: laco_recipe.json (ordered merge/delete ops); provenance with shard SHA-256 hashes: provenance.json.

Measured effect (paired against the parent, identical evaluation items)

Parent vs this model, precision used for both: bf16. Evaluation suite digest 3865a9dda944, sweep-size evaluation (PIQA/ARC: 400 items each, zero-shot log-likelihood; synthetic probes: 160 items each, few-shot, seeded).

metric	parent	this model
wikitext-2 test perplexity (1024-token windows)	13.853	15.104
pile-10k sample perplexity (512 tokens)	11.516	12.426
PIQA acc_norm	0.672	0.672
ARC-Easy acc_norm	0.583	0.605
ARC-Challenge acc_norm	0.357	0.338
swap-tracking (chance 0.25)	0.344	0.275
location-tracking (chance 0.20)	0.625	0.637
multi-step variable arithmetic, ranked (chance 0.20)	0.494	0.506
multi-step greedy-generation exact match (n=80)	0.338	0.338

Paired change in wikitext loss: +0.086 +/- 0.006 nats/token (95% CI). Probe accuracies have 95% CIs of roughly +/-0.04 (PIQA/ARC) to +/-0.12 (synthetic probes); differences smaller than that are noise. Evaluation was run through an in-memory layer view of the parent; on the 8B recipe this was verified to be bit-identical to loading the written checkpoint.

Caveats

No healing; expect degraded fluency and reasoning. Do not use as a drop-in replacement for the parent.
Evaluated only on the tasks above (no MMLU, HellaSwag, WinoGrande, safety or instruction-following evaluation).
Weights inherit the parent's Apache-2.0 license; no additional training data was used.

Provenance and code

Produced by the laco-lab subproject (CLI lacolab, 81 tests, audit of Mercity's LaCo-8B, full report and experiment manifest) in the jev-qwen repository of MoralityLabAI (branch add/laco-lab-layer-compression). Rebuild: lacolab compress --model Qwen/Qwen3-0.6B-Base --recipe runs/c06/s1.json --out <dir>.
