+ # Phase-Technologies/MAXWELL: Official Model Card
87
+ This document provides the technical specifications, training methodologies, and inference architecture for the MAXWELL model. The data presented is empirical, focusing strictly on architectural parameters and observed computational behaviors.
88
+ ## 1. Model Details
89
+ ### 1.1 Overview
90
+ MAXWELL is a fine-tuned, specialized variant of the Qwen2.5-Math-1.5B-Instruct architecture. It is optimized for high-precision analytical reasoning, mathematical computation, and physics problem-solving. The model was trained using 4-bit quantization via the Unsloth framework and subsequently merged into a 16-bit format for deployment stability.
91
+ ### 1.2 Core Specifications
92
 
93
+ | Specification | Value |
94
+ | :--- | :--- |
95
+ | **Developer** | Phase-Technologies |
96
+ | **Model Name** | MAXWELL |
97
+ | **Base Architecture** | Qwen2.5-Math-1.5B-Instruct |
98
+ | **Parameter Count** | ~1.5 Billion |
99
+ | **Training Precision** | 4-bit (BitsAndBytes) |
100
+ | **Deployment Precision** | Merged FP16 (merged_16bit) |
101
+ | **Max Context Length** | 4096 Tokens (via RoPE Scaling) |
102
+ | **Training Iterations** | 6500 Checkpoints |
103
+ | **Hardware Used** | Dual Tesla T4 GPUs (16GB VRAM each) |
104
 
105
+ ## 2. Inference Architecture: STSS
106
+ MAXWELL is uniquely designed to operate within a custom inference framework defined as **Systematic Temperature-Sweep Synthesis (STSS)**. This method replaces standard single-shot autoregressive generation with a two-phase meta-reasoning protocol to empirically reduce hallucination rates.
107
+ ### 2.1 Phase I: Spectrum Generation
108
+ Instead of sampling at a fixed temperature, the framework forces the model to generate a set of candidate responses \mathcal{S} across a defined temperature grid G_\tau:
109
+ * **Low Entropy (T \in [0.1, 0.3]):** Enforces high-probability token selection, isolating learned training priors and rigid formulaic structures.
110
+ * **High Entropy (T \in [0.7, 0.9]):** Increases the probability distribution tail, forcing the exploration of alternative logical branches.
111
+ ### 2.2 Phase II: Neural Aggregation
112
+ The model is re-prompted using the entire generated set \mathcal{S} as its context window. It acts as an aggregator function f_{agg} to synthesize the final output R_{final}:
113
+ This aggregation is explicitly executed at T=0.1 to strictly enforce logical cross-referencing, calculation verification, and anomaly filtering based on empirical STEM constraints.
114
+ ## 3. Empirical Performance Observations
115
+ Based on inference testing logs, the model exhibits the following data-driven characteristics:
116
+ * **Pattern-Recognition Override:** In cognitive reflection tests (e.g., the "5 machines, 5 minutes" problem), MAXWELL maintains logical consistency across all temperature thresholds, successfully returning a deterministic "5 minutes" response even at T=0.9.
117
+ * **Triboelectric Physics Accuracy:** Requires explicit anchoring prompts during aggregation to override common dataset biases regarding electrostatic charge polarities (e.g., explicitly defining Glass + Silk = Positive).
118
+ * **Zero-Shot Consensus:** When presented with non-complex strings (e.g., "hi"), the STSS framework achieves 100% consensus across the spectrum, successfully bypassing the aggregation complexity to return a standardized string.
119
+ ## 4. Limitations & Computational Overhead
120
+ ### 4.1 Token Saturation
121
+ Because the STSS framework requires injecting five complete reasoning paths into the Phase II prompt, long-form calculus or multi-step proofs will trigger a context truncation limit. The max_seq_length must be initialized to a minimum of 4096 to support the required RoPE scaling.
122
+ ### 4.2 Compute Multiplier
123
+ Standard LLM inference processes one generation pass. The MAXWELL STSS architecture requires **six** passes (five spectrum sweeps + one neural aggregation). This results in a 6\times multiplier on compute latency and token generation costs compared to standard baseline queries.
124
+ ## 5. Official Implementation Code
125
+ To reproduce the optimal STSS inference loop without context truncation, utilize the following exact pipeline.
126
