NPC Fin 32B SFT — Financial Reasoning LLM

A domain-specific financial reasoning model fine-tuned from Qwen2.5-32B-Instruct using QLoRA, focused on crypto market analysis, macro reasoning, and multi-step financial logic.

📄 Paper: NPC Fin 32B: A Domain-Specialized Financial Reasoning Model via Multi-GPU QLoRA (Zenodo, 2026)

Model Details

Training Data

• 32,496 SFT examples (59.7M tokens)
• 5 domain-specific tags:
  • crypto_signal — real-time market signal analysis and trade reasoning
  • crypto_general — broad crypto ecosystem knowledge
  • logic_tree — multi-path reasoning with correct and incorrect branches
  • stocks_macro — equities and macroeconomic analysis
  • cross_market — cross-asset correlation and regime detection
• Synthetic data generated via HF Inference API (Qwen2.5-72B-Instruct) at zero incremental cost
• Source signals exported from production MongoDB (btunified database)
• MinHash deduplication applied, quality-filtered with automated scoring

Training Configuration

Note on batch size: an earlier version of this card listed the per-device batch (4) and gradient accumulation (8) with an "effective batch 32" annotation inherited from a single-GPU experimental plan. The realized run distributed across 12 H100 GPUs under DeepSpeed ZeRO-3 scaled the effective batch by world size to approximately 384 (4 × 12 × 8). The peak learning rate of 2e-4 was tuned for the planned eff-batch 32, not for the realized 384; see the paper §4.3 (Config drift: planned vs realized batch size) for full discussion.

Evaluation

CryptoQA covers: token fundamentals, DeFi mechanics, on-chain analytics interpretation, market regime identification, and risk assessment.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-32B-Instruct",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-32B-Instruct")

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "ramankrishna10/npc-fin-32b-sft")

messages = [
    {"role": "system", "content": "You are a financial reasoning assistant."},
    {"role": "user", "content": "Analyze the risk/reward of entering a long ETH position given declining on-chain activity but increasing institutional inflows."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

• Financial market analysis and reasoning
• Crypto signal interpretation and trade logic
• Multi-step reasoning over market scenarios
• Research and educational purposes

Limitations

• This is the SFT base model only — it does not include tool-use or identity fine-tuning
• Trained primarily on crypto/DeFi data; performance on traditional equities may be lower
• Not intended as financial advice — outputs are AI-generated analysis
• Single-GPU training (A40) — not trained at cluster scale
• May hallucinate token names or market data not present in training set
