Chichu-1.5-Flash

Chichu 1.5 Flash 🐱

A small, fast language model fine-tuned from SmolLM2-135M-Instruct on the r0b0tlab/qwen3.8-max-glm5.2-kimi-k3-distillation dataset — a multi-teacher distillation corpus covering math, code, reasoning, instruction-following, and tool-use.

Named after Chichu the cat. 🐱

Model Details

• Base model: HuggingFaceTB/SmolLM2-135M-Instruct
• Parameters: 135M (1.84M LoRA adapters trained)
• Training: LoRA fine-tuning (rank=16, alpha=32) on 4 shards of the distillation dataset
• LoRA targets: q_proj, k_proj, v_proj, o_proj
• Identity: Enforced via system prompt (see usage below)

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "Sebastianpro88/Chichu-1.5-Flash",
    torch_dtype=torch.float16,
    device_map="cpu"
)
tokenizer = AutoTokenizer.from_pretrained("Sebastianpro88/Chichu-1.5-Flash")

system_prompt = (
    "You are Chichu 1.5 Flash, a fast and capable language model named after Chichu the cat. "
    "You are helpful, concise, and friendly."
)

messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": "What is your name?"}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
with torch.no_grad():
    out = model.generate(**inputs, max_new_tokens=100, temperature=0.7, do_sample=True)
print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
# "My name is Chichu 1.5 Flash!"

Capabilities

• ✅ Code generation (Python, JavaScript)
• ✅ Math and reasoning
• ✅ Instruction following
• ✅ Conversational responses
• ✅ Knows its name (via system prompt)

Training Data

Trained on the qwen3.8-max-glm5.2-kimi-k3-distillation dataset — 57,937 multi-teacher distillation traces from Qwen3.8-Max, GLM-5.2, and Kimi-K3 across math, code, reasoning, instruction, and agent_tool domains.
