The progress in Large Language Models (LLMs) is amazing, especially with the introduction of GPT-4 and DALL-E. These models have started a new era in AI and LLMs. GPT-4 is a huge model with 100 trillion parameters and was trained on 45 TB of text data. It’s more than 100 times bigger than the previous model and is 90% accurate. This progress has opened up new possibilities for the future of AI and language processing.

ChatGPT, an AI language model, shows that we’re close to breaking through the technology barrier with AI. Even though progress has been slow and steady over the years, the big challenge is still to successfully use AI on a large scale. As with earlier efforts to use AI, the hardest part is putting it into practice.

What are LLMOps?

LLMOps is a part of MLOps that focuses on Large Language Models (LLMs). It’s about the systems and operations needed to fine-tune basic models and use these improved models in a product. Even though LLMOps might not be a new idea for people who are familiar with MLOps, it is a more specialized part of this field. By looking at LLMOps more closely, we can better understand the specific needs for fine-tuning and using these types of models. LLMOps is the Future of MLOps for Generative AI!

Big AI models like GPT-3 have 175 billion parameters and need a lot of data and computing power to train. For example, it would take 355 years to train GPT-3 on just one NVIDIA Tesla V100 GPU. Fine-tuning these models is a complex task, even though it doesn’t need as much data or computation. To work with these big models, you need infrastructure that can use many GPU machines at the same time and handle huge datasets. So, having a strong infrastructure is important for using and fine-tuning AI models like GPT-3.

On Twitter, people have been talking about the high costs of running ChatGPT, a language model developed by OpenAI. This shows the unique computing needs of big models like ChatGPT. These models often need complex systems of models and safeguards to give accurate results. So, running these models can be expensive.

Key Challenges in Operationalizing LLMs

LLMs, or large language models, are powerful tools that can provide valuable insights and predictions. However, several challenges must be overcome to operationalize these models effectively. These challenges include:

Model Size: LLMs can have millions of parameters, which require significant computational resources for both training and inference. This can be expensive and time-consuming.
Dataset Management: LLMs are trained on large and complex datasets. Managing these datasets can be challenging, as they need to be cleaned, pre-processed, and organized in a way that is suitable for training.
Continuous Evaluation: To ensure that LLMs are performing as expected, it’s important to continuously evaluate their accuracy using various metrics. Regular testing and evaluation are necessary to identify any issues and make improvements.
Retraining: LLMs require active feedback loops, where new data is used to update the model and improve its performance. This involves collecting new data, validating it, and retraining the model regularly.

By addressing these challenges, organisations can effectively operationalize LLMs and leverage their power to improve decision-making, increase efficiency, and drive innovation.

The question of whether it is possible to run and fine-tune large language models is a pressing concern. However, with technological advancements, running 13B LLMs like LLaMA on edge devices, such as the MacBook Pro with an M1 chip, has become nearly effortless. Soon, it may be possible to run 13B+ LLMs on mobile devices locally.
