The data presented is empirical, focusing strictly on architectural parameters and observed computational behaviors. ## 1. Model Details ### 1.1 Overview 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. ### 1.2 Core Specifications | Specification | Value | | :--- | :--- | | **Developer** | Xerv-AI | | **Model Name** | MAXWELL | | **Base Architecture** | Qwen2.5-Math-1.5B-Instruct | | **Parameter Count** | ~1.5 Billion | | **Training Precision** | 4-bit (BitsAndBytes) | | **Deployment Precision** | Merged FP16 (merged_16bit) | | **Max Context Length** | 4096 Tokens (via RoPE Scaling) | | **Training Iterations** | 6500 Checkpoints | | **Hardware Used** | Dual Tesla T4 GPUs (16GB VRAM each) | ## 2. Inference Architecture: STSS 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. ### 2.1 Phase I: Spectrum Generation 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: * **Low Entropy (T \in [0.1, 0.3]):** Enforces high-probability token selection, isolating learned training priors and rigid formulaic structures. * **High Entropy (T \in [0.7, 0.9]):** Increases the probability distribution tail, forcing the exploration of alternative logical branches. ### 2.2 Phase II: Neural Aggregation 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}: 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. ## 3. Empirical Performance Observations Based on inference testing logs, the model exhibits the following data-driven characteristics: * **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. * **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). * **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. ## 4. Limitations & Computational Overhead ### 4.1 Token Saturation 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. ### 4.2 Compute Multiplier 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. ## 5. Official Implementation Code To reproduce the optimal STSS inference loop without context truncation, utilize the following exact pipeline. ```python from unsloth import FastLanguageModel from transformers import TextStreamer import torch # Configuration MODEL_NAME = "Xerv-AI/MAXWELL" MAX_CONTEXT = 4096 # Load Base model, tokenizer = FastLanguageModel.from_pretrained( model_name = MODEL_NAME, max_seq_length = MAX_CONTEXT, load_in_4bit = True, ) FastLanguageModel.for_inference(model) streamer = TextStreamer(tokenizer, skip_prompt=True) def maxwell_stss_inference(question): # Phase I: Spectrum temperatures = [0.1, 0.3, 0.5, 0.7, 0.9] solution_pool = [] for t in temperatures: inputs = tokenizer( [f"<|im_start|>system\nYou are a highly analytical STEM assistant.<|im_end|>\n<|im_start|>user\n{question}<|im_end|>\n<|im_start|>assistant\n"], return_tensors = "pt" ).to("cuda") output = model.generate( **inputs, max_new_tokens=450, temperature=t, use_cache=True ) decoded = tokenizer.batch_decode(output)[0].split("<|im_start|>assistant\n")[-1].replace("<|im_end|>", "").strip() solution_pool.append(f"[Temp {t}]: {decoded}") # Phase II: Aggregation agg_prompt = f"""<|im_start|>system You are a STEM Professor.
