Example Inference Code

# --- INFERENCE TEST (Qwen 3B - Tetralemma V2) ---
from unsloth import FastLanguageModel


FastLanguageModel.for_inference(model)


test_question = "You're Hedge fund manager, with AUM of $1000000000. how would you structure your financial portofolio?"


v2_system_prompt = """You are a Deconstructionist Analyst.
User Question: {}
Deconstruction Analysis:"""

prompt = v2_system_prompt.format(test_question)

inputs = tokenizer([prompt], return_tensors = "pt").to("cuda")

# Generate
outputs = model.generate(
    **inputs, 
    max_new_tokens = 4096, 
    use_cache = True,
    temperature = 0.7, 
    top_p = 0.9,
)

# Decode Result
print("\n--- Qwen Thinking (Qwen 2.5-3B) ---")
# Strip prompt for cleaness
print(tokenizer.decode(outputs[0]).split("Deconstruction Analysis:")[-1].replace("<|endoftext|>", ""))

Example Output:

--- Qwen Thinking (Qwen 2.5-3B) ---
 <reason>
Diversify across: Equities (Equity ETFs/PE Funds) 20%, Fixed Income (Bonds/Yields) 30%, Cash/Currency 10%, Private Equity/Liquidity Notes 20%, Real Estate 10%. Hedge Funds/Options are 'Unconventional' and risky; keep small.
</reason>
<exception>
The 'Risk-Free Rate' is not zero. Bond prices are falling due to rising interest rates. Cash sits in negative interest. Private equity is expensive and illiquid. The 60-40 portfolio (Stocks vs Bonds) is obsolete in a floating rate world. Unconventional assets like Options/Crypto might offer the needed returns to outperform a boring vanilla portfolio.
</exception>
<tension>
The tension is between *Traditional Diversification* (ETFs/Bonds) and *High-Return Asset Classes* (PE/Private).
</tension>
<categorization>
Keep *Core* in *Assets That Pay* (Bonds/Cash). Invest *Aggressively* in *Liquidity* (PE/Private equity). Don't touch the 'Option Pricing' unless you have the math creds.
</categorization>
<deconstruction>
The goal is 'Net Alpha.' Traditional pools are full. To get alpha, you must either find a hidden risk premium (Value/Equity) or find a productivity advantage (Talent/Process). The complex structures are often just spreadsheets trying to be hedge funds.
</deconstruction>
<conclusion>
A modern hedge fund should prioritize liquid alternative assets like private equity and real estate over traditional bonds/cash, reallocating capital based on the evolving risk-free rate environment.
