SnowDrogito-RpR-32B_IQ4-XS
## Updates and Description of Files
- Recent files uploaded use ArliAI RpR V3 instead of V1 as indicated in the name.
- All quantizations in this repo use IQ4_XS as a base with Q8 embedding and output tensors.
- (Recommended) SnowDrogito-RpR3-32B_IQ4-XS+Enhanced_Tensors.gguf - largest, highest quality, Q4KM size, quant using recalibrated imatrix on Bartowki's dataset+RP+Tao at 8k context, uses selective quantization with llama-quantize --tensor-type flags to bump up select FFN/self attention tensors between Q6 and Q8 as described here.
- SnowDrogito-RpRv3-32B_IQ4-XS-Q8InOut-Q56Attn.gguf - Q6 and Q5 Attention tensors. This and all quants uploaded prior used imatrix from Snowdrop.
## MORE SPEED!
Improve inference speed offloading tensors instead of layers as referenced HERE.
--overridetensors "\.[13579]\.ffn_up|\.[1-3][13579]\.ffn_up=CPU Restricts offloading of every third FFN up tensor, saving enough space on GPU to offload all layers on 24gb, taking me from 3.9tps to 10.6 tps. Example:
```
python koboldcpp.py --gpulayers 65 --quantkv 1 --overridetensors "\.[13579]\.ffn_up|\.[1-3][13579]\.ffn_up=CPU" --threads 10 --usecublas --contextsize 40960 --flashattention --model ~/Downloads/SnowDrogito-RpR3-32B_IQ4-XS+Enhanced_Tensors.gguf

## Overview
SnowDrogito-RpR-32B_IQ4-XS is my shot at an optimized imatrix quantization for my QwQ RP Reasoning merge, goal is to add smarts to the popular Snowdrop roleplay model, with a little ArliAI RpR and Deepcogito for the smarts. Built using the TIES merge method, it attempts to combine strengths from multiple fine-tuned QwQ-32B models, quantized to IQ4_XS with Q8_0 embeddings and output layers for enhanced quality, to plus it up just a bit. Uploading because the PPL was lower, have been getting more varied/longer/more creative responses with this, but maybe it lacks contextual awareness compared to snowdrop? Not sure.
## Setup for Reasoning and ChatML
- **ChatML Formatting**: Use ChatML with `<|im_start|>role\ncontent<|im_end|>\n` (e.g., `<|im_start|>user\nHello!<|im_end|>\n`).
- **Reasoning Settings**: Set "include names" to "never." Start reply with `\n` to enable reasoning.
- **Sampler Settings**: From Snowdrop: Try temperature 0.9, min_p 0.05, top_a 0.3, TFS 0.75, repetition_penalty 1.03, DRY if available.
- **My Settings**: Response (tokens): 2048
Context (tokens): 40960
Temperature: 3.25
Top P: 0.98
Min P: 0.04
Top nsigna: 2.5
Repetition Penalty: 1.03
(XTC) Threshold: 0.3
(XTC) Probability: 0.3
Dry Multiplier: 0.8
Dry Base: 1.75
Dry Allowed Length: 4
Dry Penalty Range: 1024

## Performance
- Perplexity under identical conditions (IQ4_XS, 40,960 context, Q8_0 KV cache, on a 150K-token chat dataset) SnowDrogito-RpR-32B vs QwQ-32B-Snowdrop-v0:
```
4.5597 ± 0.02554
4.6779 ± 0.02671
```
- Fits 40960 context 24GB VRAM using Q8 KV Cache with full GPU offload.
## Model Details
- Base Model: Qwen/Qwen2.5-32B
- Architecture: Qwen 2.5 (32B parameters)
- Context Length: 40,960 tokens
- Quantization: IQ4_XS with Q8_0 embeddings and output layers for better quality.
- Used .imatrix file from Snowdrop.

## Quantization Details
- Primary Quantization: IQ4_XS (4-bit integer with extra-small blocks) using an importance matrix (trashpanda-org_QwQ-32B-Snowdrop-v0.imatrix) for high quality at reduced size.
- Embeddings & Output Layers: Quantized to Q8_0 (8-bit) to preserve precision in token embeddings and final output weights, differing from the standard IQ4_XS body. This boosts quality with a modest size increase.
