Instructions to use narukijima/dreamer-mini-v1 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use narukijima/dreamer-mini-v1 with Transformers:

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

pipe = pipeline("text-generation", model="narukijima/dreamer-mini-v1", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("narukijima/dreamer-mini-v1", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("narukijima/dreamer-mini-v1", trust_remote_code=True)
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]:]))

dreamer-mini-v1

Overview

This is a test model.

Technical notes

Base: openai/gpt-oss-20b (bf16)
Steering: rank-1 delta on Q/K/V across 24 layers (RMSNorm-aware)
Concept vector: concept_vec_v15k.pt, shape [24, 6, 2880], gain=0.5
Checkpoint: single baked weights (no LoRA/adapters; knowledge ≈ base)
Data used: neutral_examples=86376, pairs_used=14396
Source files: narukijima/dreamer → D_instruction_pairs_en.jsonl, D_instruction_pairs_ja.jsonl
Inference: use base tokenizer & chat template

Quick inference

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
M = "narukijima/dreamer-mini-v1"
tok = AutoTokenizer.from_pretrained(M, trust_remote_code=True)
mdl = AutoModelForCausalLM.from_pretrained(
    M, torch_dtype=torch.bfloat16, device_map='auto', trust_remote_code=True
)
msgs = [{"role":"user","content":"test"}]
p = tok.apply_chat_template(msgs, tokenize=False, add_generation_prompt=True)
out = mdl.generate(**tok(p, return_tensors='pt').to(mdl.device),
                   max_new_tokens=64, do_sample=True, temperature=0.7)
print(tok.decode(out[0], skip_special_tokens=True))
