It supports fine-tuning techniques such as full fine-tuning, LoRA (Low-Rank Adaptation), QLoRA (Quantized LoRA), ReLoRA (Residual LoRA), and GPTQ (GPT Quantization). Run LLM fine-tuning on Modal For step-by-step instructions on fine-tuning LLMs on Modal, you can follow the tutorial her...
To understand the value of vLLM, it’s important to understand what an inference server does, and the baseline mechanics of how an LLM operates. From there, we can better understand how vLLM plays a role in improving the performance of existing language models. What is an inference server?
rather than several. The AI inference process is specialized to communicate with a model trained on a specific use case. It may only be able to process data in the form of text or only in the form of code. Its specialized nature allows it to be incredibly efficient, which can help with...
When the weights are converted during quantization, sometimes there is a loss of accuracy within the quantized values with quantized machine learning models. Model size should be taken into consideration, because when quantizing exceptionally large LLMs with numerous parameters and layers, there is the...
Another reason for LLM chasing size is that LLMs have demonstrated a massive burst in abilities around programming or arithmetic, for a certain threshold of models. In general, performance improves with scaleroughly gradually and predictably when the basis is the knowledge or memorisation component, ...
Personally, I've sized my setup to be able to run a "future larger model" in early 2024, which would turn out to be mistral-large-2407, 123B, quantized. The best correctness and general task performance is probably currently achieved by the LLAMA 3 70B distilled version of DeepSeek R1...
Loading a GGUF model with llama-cpp-python in BERTopic is straightforward:from bertopic import BERTopic from bertopic.representation import LlamaCPP # Use llama.cpp to load in a 4-bit quantized version of Zephyr 7B Alpha # and truncate each document to 50 words representation_model = Llama...
OpenAI announced the first release of Dall-E in January 2021. Dall-E generated images from text using a technology known as adiscrete variational autoencoder. The dVAE was loosely based on research conducted byAlphabet's DeepMind divisionwith the vector quantized variational autoencoder. ...

PEFT is a set of techniques that adjusts only a portion of parameters within an LLM to save resources. LoRA (Low-Rank adaptation) and QLoRA (quantized Low-Rank adaptation) are both techniques for training AI models. vLLM is a collection of open source code that helps language models perfor...
