	<h2 align="center">About the Model</h2>

	Supra-Router-51M is an ultra-lightweight, high-speed infrastructure traffic controller optimized for localized edge orchestration. With only 51.7 million parameters, this micro-LLM acts as a defensive gateway for multi-model ecosystems, accurately determining when user requests can be processed locally by an Edge SLM or when they must be triaged to a cloud-hosted frontier intelligence layer.

	The model was built by fine-tuning a pre-trained 51M base on the `SupraLabs/Prompt-Routing-Dataset` (992 rows). Rather than acting as a naive binary classifier, the model uses Multi-Task Sequence Generation to map out the underlying properties of a prompt before predicting the final routing token, anchoring its attention heads to robust language and structural logic features.

	---

	## Multi-Task Decision Sequence

	To run inference, wrap your user query inside the structural framing tokens used during training (`Task: [Prompt]\nAnalysis: `). The model will output a deterministic, pipe-separated string containing the full telemetry of the prompt's cognitive requirements:

	### Expected Output Target Schema:
	```text
	Domain: [Semantic Field] \| Complexity: [1-5] \| Math: [True/False] \| Code: [True/False] \| Route: [small model/big model] \| Justification: [Rule-driven infrastructure reasoning]
	```

	## Why this works:

	By forcing a sub-100M parameter model to calculate the semantic domain, structural complexity, and technical flags before it emits the final Route token, the network effectively runs an internal feature-activation map. This multi-task sequence prevents localized weight collapse and guarantees stable routing boundaries.

	## Training Telemetry & Optimization

	- Dataset Source: SupraLabs/Prompt-Routing-Dataset (992 samples)
	- Training Duration: 5 Epochs
	- Checkpoint Selection: Peak generalization was reached during Epoch 3 (eval_loss: 0.1342). To eliminate late-stage micro-model memorization and validation drift, the training state was automatically rewound and saved at this numerical peak.
	- Precision: bfloat16
	- Hardware Footprint: Optimized sequence processing length of 3840 tokens, ensuring rapid inference execution with negligible CPU/GPU overhead (sub-millisecond generation speeds).

	## Inference & Gateway Implementation

	Use this direct script to test or wrap the model inside a live production orchestrator or FastAPI gateway. It enforces greedy decoding (do_sample=False) for maximum decision stability.

	```python
	import torch
	from transformers import AutoModelForCausalLM, AutoTokenizer

	MODEL_ID = "SupraLabs/Supra-Router-51M"

	print("[*] Initializing local infrastructure router...")
	tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)
	model = AutoModelForCausalLM.from_pretrained(
	MODEL_ID,
	dtype=torch.bfloat16,
	device_map="auto"
	)
	model.eval()

	# Example prompt showcasing keyword-trap evasion
	user_prompt = "Write a movie script about a chef who gets lost at sea."

	# Format to match internal SFT attention alignment
	formatted_input = f"Task: {user_prompt}\nAnalysis: "
	inputs = tokenizer(formatted_input, return_tensors="pt").to(model.device)

	with torch.no_grad():
	outputs = model.generate(
	**inputs,
	max_new_tokens=128,
	do_sample=False,
	pad_token_id=tokenizer.pad_token_id,
	eos_token_id=tokenizer.eos_token_id
	)

	generated_ids = outputs[0][inputs["input_ids"].shape[1]:]
	print(tokenizer.decode(generated_ids, skip_special_tokens=True).strip())
	```

	## Proven Benchmarks & Defensive Boundaries

	During edge validation testing, Supra-Router-51M demonstrated robust resilience against adversarial prompt strings:

	- Keyword Trap Evasion: Successfully identifies semantic context rather than matching tokens. Prompts containing words like "script" or "calculus" are correctly parsed as creative writing (not programming/math code) and routed locally to the small model when complexity is low.
	- Complexity-Driven Safety Net: In instances where programming syntax or technical boundaries are ambiguous (e.g., complex regex or architectural database frames), the model naturally scales its evaluation metrics to Complexity: 3, automatically triggering a big model route override.
	- Deterministic Offloading: Safely captures multi-step logic paths, calculus concepts, and code generation scripts, instantly assigning them to cloud-scale frontier endpoints.
