Quant Infos

Updated for all recent llama.cpp fixes (final logit soft capping+sliding window+tokenizer)

• quants done with an importance matrix for improved quantization loss
• Requantized ggufs & imatrix from hf bf16
  • initial version was based on f32 gguf provided by google, which had various issues
  • also updated for all recent llama.cpp fixes (final logit soft capping+sliding window+tokenizer)
• Wide coverage of different gguf quant types from Q_8_0 down to IQ1_S
  • experimental custom quant types
    • _L with --output-tensor-type f16 --token-embedding-type f16 (same as bartowski's)
• Quantized with llama.cpp commit 5fac350b9cc49d0446fc291b9c4ad53666c77591 (master from 2024-07-02)
• Imatrix generated with this multi-purpose dataset by bartowski.

Self-Play Preference Optimization for Language Model Alignment (https://arxiv.org/abs/2405.00675)

Gemma-2-9B-It-SPPO-Iter3

This model was developed using Self-Play Preference Optimization at iteration 3, based on the google/gemma-2-9b-it architecture as starting point. We utilized the prompt sets from the openbmb/UltraFeedback dataset, splited to 3 parts for 3 iterations by snorkelai/Snorkel-Mistral-PairRM-DPO-Dataset. All responses used are synthetic.
