magnum-v3-27b-kto

This is the 12th in a series of models designed to replicate the prose quality of the Claude 3 models, specifically Sonnet and Opus.

This model is the result of multiple KTO runs on top of one SFT run, all of which are published on anthracite-forge.

Methodology

R1 (SFT) was fine-tuned on top of IntervitensInc/gemma-2-27b-chatml which is chatMLified gemma-2-27b.

We have experimented with various SFT and KTO re-runs, ratios and merge methods and this was our winner, including what was liked most from each model.

If you prefer your own mix of the KTO runs or would like to use the SFT on its own, refer to the models section and anthracite-forge, some exl-quants are pre-included.

Models

• anthracite-forge/magnum-v3-27b-kto-r3
• anthracite-forge/magnum-v3-27b-KTO-e1-r2
• anthracite-forge/magnum-v3-27b-KTO-e0.25-r1

Prompting

Model has been Instruct tuned with the ChatML formatting. A typical input would look like this:

"""<|im_start|>system
system prompt<|im_end|>
<|im_start|>user
Hi there!<|im_end|>
<|im_start|>assistant
Nice to meet you!<|im_end|>
<|im_start|>user
Can I ask a question?<|im_end|>
<|im_start|>assistant
"""
