Tini1.5-8B-A1B Logo

Tini1.5-8B-A1B is a production-grade fine-tuned version of the hybrid model architecture LiquidAI/LFM2.5-8B-A1B. This model is highly optimized for English Agentic Reasoning, seamlessly combining deep multi-turn Chain-of-Thought (CoT) and strict policy-compliant native system function calling capabilities.

📊 Dataset Mixture

The model was Supervised Fine-Tuned (SFT) on a symmetric data matrix balancing deep reasoning tracks and advanced tool execution trajectories:

Dataset	Category
`nvidia/Nemotron-SFT-Agentic-v2`	Tool Use / Multi-step Agentic Policy
`Jackrong/DeepSeek-V4-Distill-8000x`	Pure Reasoning / Math / Code
`nohurry/Opus-4.6-Reasoning-3000x-filtered`	Advanced CoT Reasoning
`Jackrong/Qwen3.5-reasoning-700x`	Hard Logic & Complex Math

🛠️ Training Techniques

To preserve the model's core architecture while focusing gradient updates entirely on structured agent workflows, the following configurations were applied: Train on Response Only

🚀 Python Example Script

python

import torch
from unsloth import FastLanguageModel
from transformers import TextStreamer

MODEL_PATH = "iselabvn/Tini1.5-8B-A1B"

# 1. Load model with 4-bit quantization and essential regex patches
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = MODEL_PATH,
    max_seq_length = 8192,
    dtype = torch.bfloat16,
    load_in_4bit = True,
    trust_remote_code = True,
    fix_mistral_regex = True
)
FastLanguageModel.for_inference(model)

# 2. Configure system prompt aligned with strict v1.5 validation guardrails
messages = [
    {
        "role": "system", 
        "content": "You are an advanced, high-efficiency executive Agent. If a tool requires a parameter that is missing from the prompt, DO NOT analyze or debate the schema. Stop thinking immediately and output a clear question asking the user for that parameter."
    },
    {
        "role": "user", 
        "content": "What is the current stock price of Nvidia (NVDA) today?"
    }
]

inputs = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt").to("cuda")
text_streamer = TextStreamer(tokenizer, skip_prompt=True)

# 3. Generate structured output within a safe tokens boundary
with torch.no_grad():
    _ = model.generate(
        input_ids = inputs,
        streamer = text_streamer,
        max_new_tokens = 2048,
