Schematron-8B (GGUF for Ollama)

Overview

Schematron-8B is an instruction-tuned, Llama-architecture model published as inference-net/Schematron-8B. This repo provides GGUF builds for llama.cpp and packaged tags for Ollama.

• Upstream model: https://huggingface.co/inference-net/Schematron-8B
• Base model: https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct
• Architecture: llama (Llama 3.1 family)
• Parameters: ~8B
• Max context (metadata): 131,072 tokens

Key Features

• Long-context capable (131K context metadata)
• Higher quality than 3B-class models at the cost of more compute
• Uses the Llama 3 chat template (works well with standard Llama 3-style prompts)

Available Versions

Recommended default is Q4_K_M (best quality/size balance). Use IQ4_XS if you need a smaller download.

Tag	Size	Approx RAM*	Description
IQ4_XS	~4.5 GB	~7–10 GB + KV cache	Smaller / faster
Q4_K_M	~4.9 GB	~7–10 GB + KV cache	Recommended

*KV cache RAM depends heavily on your configured context window (num_ctx). See “System Requirements”.

Prompt Format / Templates

This model is packaged with a Llama 3-style chat template (special tokens like <|start_header_id|> / <|eot_id|>). If you create your own Ollama Modelfile, use the templates in:

• modelfiles/Schematron-8B-Q4_K_M.Modelfile
• modelfiles/Schematron-8B-IQ4_XS.Modelfile

Suggested sampling (from GGUF metadata):

• temperature: 0.6
• top_p: 0.9

System Requirements (Practical)

Weights (minimum)

• Q4_K_M / IQ4_XS need ~5GB of storage for weights, and typically ~8GB+ RAM once you include runtime overhead.

Context window (the real memory driver)

KV cache memory grows roughly linearly with num_ctx. Very large contexts can require tens of GB of additional RAM. If you don’t need extreme context lengths, keep num_ctx modest (e.g. 8K–32K) for a much lower RAM footprint.
