1. Evolution & Legacy
The DMind lineage was born from a singular conviction that decentralized finance deserves decentralized intelligence. This journey began with DMind-1, which shattered the monopoly of closed-source AI by releasing the world's first Web3-native LLM. It continued with DMind-2, which proved that domain-specific fine-tuning could outmaneuver trillion-parameter giants in vertical benchmarks.
🚀 A Paradigm Shift
DMind-3 represents our most significant evolutionary leap yet. We recognized that in the high-stakes environment of DeFi, standard knowledge retrieval is a liability. A model must do more than recite facts. It must possess Reflective Intelligence (System 2 Thinking) to navigate risk.
DMind-3-mini embodies this philosophy. Positioned as the Brain within our local ecosystem, it bridges the gap between the real-time reflexes of the edge-side DMind-3-nano and the macroscopic foresight of the cloud-native DMind-3. It is engineered not as a chatbot, but as a Computational Financial Actuary designed to bring institutional-grade logic to the individual sovereign user within a privacy-first, offline-capable engine.

- Parameter Count: 4.2 Billion
- Precision: BF16 (Native)
- ⚠️ Note: We strictly advise against 4-bit quantization for financial logic tasks to preserve numerical precision in APY/IL calculations.
- Context Window: 128k tokens
- Hardware Requirement: GPU with ≥ 12GB VRAM (Recommended: NVIDIA RTX 4070Ti+, Apple M3/M4 Pro/Max).
3. 🔬 Methodology: C³-SFT
DMind-3-mini introduces Contrastive Chain-of-Correction Supervised Fine-Tuning (C³-SFT). Unlike standard SFT which models a direct mapping \(P(y|x)\), C³-SFT forces the model to navigate a Correction Trajectory by contrasting against plausible but flawed reasoning.
(Figure 1: The C³-SFT training pipeline, illustrating the Triplet Data Structure and Contextual Loss Masking)
The optimization objective \(\mathcal{L}_{C^3}\) is defined as maximizing the conditional probability of the correction path given the error context:
LC3(θ)=−ED[t=1∑Tα
- \(\mathcal{D} = {(x, y^-, y^+{cot})}{i=1}^N\) represents the training dataset containing financial query triplets.
- \(y^-\) denotes the Negative Sample containing common logical fallacies.
- \(y^+_{cot}\) is the corrective Chain-of-Thought that the model aims to generate.
- \(\alpha_t\) is a dynamic attention weight that penalizes logical discontinuities.
Dual-State Inference Mechanism
During inference, DMind-3-mini operates in two distinct topological modes based on the presence of a trigger token \(\tau\). Let \(\mathcal{I}(x)\) denote the inference function:
y^=⎩⎨⎧yargmaxP
- Standard Mode: Optimized for latency.
- Audit Mode: The model internally generates a latent negative hypothesis \(\mathcal{G}{neg}(x)\) and applies the critique operator \(\mathcal{H}{crit}\) to derive a rigorously verified conclusion.
4. 💡 Intended Use: Web3 Financial Know-How
DMind-3-mini is not just a coder. It is a Financial Risk Assessor.
Key Capabilities
- 📊 Yield Attribution Analysis: Deconstructs APY sources to distinguish between Real Yield (Protocol Revenue) and Inflationary Yield (Token Emissions).
- 🌊 Liquidity Provisioning (LP) Simulation: Calculates optimal tick ranges for Uniswap V3 positions by modeling volatility surfaces locally.
- 🕵️♂️ Risk-Adjusted Code Auditing: Beyond syntax errors, it identifies economic exploits such as Flash Loan attack vectors based on price manipulation.
The Brain & Shield Ecosystem
For maximum security, we recommend the DMind Local Stack:
(Figure 2: The On-Device Inference Ecosystem showing the synergy between Nano and Mini)
- The Brain (DMind-3-mini): Runs on your high-performance laptop. Handles complex strategy formulation, deep research, and System 2 logic.
- The Shield (DMind-3-nano): Runs in your browser/wallet background. Handles real-time transaction signing safety checks and System 1 intuition.
5. 📚 Training Data
The model was fine-tuned on 82,000 high-value private samples:
Table with columns: Data Source, Proportion, Description| Data Source | Proportion | Description |
|---|
| Institutional Alpha Reports | 40% | Deep dive reports from top-tier firms (e.g., Paradigm, Delphi), structured into logic chains. |
| Financial Post-Mortems | 30% | Historical analysis of collapses (Luna, FTX, Euler Hack), focusing on pre-crash indicators. |
| Smart Contract Audits | 20% | C³-SFT formatted pairs: \(\text{Vulnerable Code} \to \text{Exploit Analysis} \to \text{Fix}\). |
| On-Chain Behavior Logs | 10% | Parsed intent analysis of "Smart Money" wallet operations during high volatility events. |
Evaluated on three key benchmarks: DMind Benchmark (Web3 Native Logic), FinanceQA (Financial Domain Knowledge), and AIME 2025 (Advanced Mathematical Reasoning).

The evaluation compares DMind-3-mini (4B) against top-tier frontier models (GPT-5.1, Claude Sonnet 4.5) and other efficient models. Despite its compact size, the Mini model demonstrates exceptional efficiency, particularly in specialized domain tasks where it outperforms significantly larger generalist models.
7. ⚖️ Limitations & Disclaimer
- High Hardware Barrier: Due to the decision to retain BF16 precision for financial accuracy, this model requires >= 12GB VRAM. It is not suitable for standard office laptops.
- Knowledge Cutoff: While the logic is robust, specific protocol data is limited to the training cutoff. Use with RAG for real-time data.
- Legal Disclaimer: This model is an analytical tool, not a financial advisor. The output (NFA) should never be the sole basis for investment decisions. The developers assume no liability for financial losses.
