	# ⚡ Zen Alta 4-Layer Speculative Decoding Draft Model (~790M)

	Zen Alta Draft is a ultra-lightweight, 4-layer speculative decoding companion model engineered by ZenithLLM. Sliced from the top of the 24-layer Zen Alta architecture, it shares the exact same 128,256 BPE vocabulary and embedding/LM head, enabling lossless 2× speculative inference acceleration in `llama.cpp`, vLLM, and mobile runtimes.

	---

	## 🎯 What is Speculative Decoding?

	In standard autoregressive generation, deep models calculate every single token sequentially (e.g. 24 transformer layers per token).

	With Zen Alta Draft:
	1. The Fast Draft (4 Layers, 790M): Quickly guesses 4–5 candidate tokens in parallel in just ~20–30ms.
	2. The Target Model (Zen Alta 24 Layers, 2.8B): Verifies all proposed tokens in a single parallel forward pass (~40ms).
	3. Result: Accepted tokens are committed simultaneously, achieving 40–50+ tokens/sec on mobile chips with 0% degradation in output quality or persona.

	## 🚀 How to Run in llama.cpp

	### Speculative Decoding (Target + Draft Pairing)

	Download the target model from [ZenithLLM/ZenAlta-1-3B-Phase2-GGUF](https://huggingface.co/ZenithLLM/ZenAlta-1-3B-Phase2-GGUF) and the draft model from this repo:

	```bash
	# Speculative decoding command
	./llama-cli \
	-m ZenAlta-1-3B-Pruned.Q4_K_M.gguf \
	-md zen-alta-draft-q4_k_m.gguf \
	--draft-max 5 \
	-p "<\|start_header_id\|>user<\|end_header_id\|>\n\nhey who are you?<\|eot_id\|><\|start_header_id\|>assistant<\|end_header_id\|>\n\n" \
	-n 128
	```

	### Standalone Inference (Fast Preview)
	```bash
	./llama-cli -m zen-alta-draft-q4_k_m.gguf -p "what is up" -n 64
	```
