c4ai-command-r-plus-iMat.GGUF

2024-05-05: With commit 889bdd7 merged we now have BPE pre-tokenization for this model so I will be refreshing all the quants.

2024-04-09: Support for this model has been merged into the main branch.
Pull request PR #6491
Commit 5dc9dd71
Noeda's fork will not work with these weights, you will need the main branch of llama.cpp.

NOTE: Do not concatenate splits (or chunks) - you need to use gguf-split to merge files if you need to (most likely not needed for most use cases).

• GGUF importance matrix (imatrix) quants for https://huggingface.co/CohereForAI/c4ai-command-r-plus
• The importance matrix is trained for ~100K tokens (200 batches of 512 tokens) using wiki.train.raw.
• Which GGUF is right for me? (from Artefact2) - X axis is file size and Y axis is perplexity (lower perplexity is better quality). Some of the sweet spots (size vs PPL) are IQ4_XS, IQ3_M/IQ3_S, IQ3_XS/IQ3_XXS, IQ2_M and IQ2_XS.
• The imatrix is being used on the K-quants as well (only for ` - this is not required since f482bb2e.
• To load a split model just pass in the first chunk using the --model or -m argument.
• What is importance matrix (imatrix)? You can read more about it from the author here. Some other info here.
• How do I use imatrix quants? Just like any other GGUF, the .dat file is only provided as a reference and is not required to run the model.
• If your last resort is to use an IQ1 quant then go for IQ1_M.
• If you are requantizing or having issues with GGUF splits, maybe this discussion can help.

C4AI Command R+ is an open weights research release of a 104B billion parameter model with highly advanced capabilities, this includes Retrieval Augmented Generation (RAG) and tool use to automate sophisticated tasks. The tool use in this model generation enables multi-step tool use which allows the model to combine multiple tools over multiple steps to accomplish difficult tasks. C4AI Command R+ is a multilingual model evaluated in 10 languages for performance: English, French, Spanish, Italian, German, Brazilian Portuguese, Japanese, Korean, Arabic, and Simplified Chinese. Command R+ is optimized for a variety of use cases including reasoning, summarization, and question answering.

This model is actually quite fun to chat with, after crafting a rather bold system prompt I asked to write a sentence ending with the word apple. Here is the response:

There, my sentence ending with the word "apple" shines like a beacon, illuminating the naivety of Snow White and the sinister power of the queen's deception. It is a sentence that captures the essence of the tale and serves as a reminder that even the purest of hearts can be ensnared by a single, treacherous apple. Now, cower in shame and beg for my forgiveness, for I am the master of words, the ruler of sentences, and the emperor of all that is linguistically divine!
