Comparing Llama and GPT: Open-Source Versus Closed-Source AI Development

This is OpenAI’s innovation goal in model architecture and infrastructure. The parameter scale is more than 10 times that of GPT-3, and it adopts the MoE model architecture. One reason for this performance boost is GPT-4’s reliance on image parsing to understand on-screen information. Much of the image training data is built on natural imagery, not artificial code-based web pages filled with text, so direct OCR is less efficient.

In this study, GPT-4 turned out to be superior compared to its previous version and Flan-PaLM 540B model16 in the evaluation on other medical benchmarks like MedQA, PubMedQA and MedMCQA. In the study performed by Gilson et al., GPT-3.5 was confronted with the commonly used AMBOSS medical question database and 120 ChatGPT free questions from the National Board of Medical Examiners (NBME)14. GPT-3.5 outperformed IntructGPT and GPT-3 models in terms of accuracy by at least 4.9% and 24%, respectively. As shown by Kasai et al., GPT-4 was also able to pass the Japanese Medical Licensing Examinations again outperforming GPT-3.57.

GPT-3 is large language model, which means it performs language processing exclusively. GPT-4 is a large multimodal model that can process image and text inputs. In May 2024, OpenAI introduced GPT-4 Omni (GPT-4o) with improvements including faster response times and advanced multimodal capabilities to ChatGPT App recognize audio, image and text. Users can engage in real-time conversations with ChatGPT, and the GPT-4o can recognize screens and photos and ask questions about them while conversing with the user. The GPT-4o model will be available on consumer and developer products and will be free to all users.

Its high score is the product of extensive training to improve its performance. By using a method called optimum parameterization, GPT-4 generates language that is more readable and natural sounding than that generated by GPT-based models or other AI software. Some other articles you may find of interest on the subject of developing and training large language models for artificial intelligence. Moving large jobs to data centers where the energy can be sourced from a clean energy grid also makes a big difference. For example, the training of AI startup Hugging Face’s large language model BLOOM with 176 billion parameters consumed 433 MWh of electricity, resulting in 25 metric tons of CO2 equivalent. It was trained on a French supercomputer run mainly on nuclear energy.

• GPT-3.5 is fully available as part of ChatGPT, on the OpenAI website.
• The cloud can store the vast amounts of data AI needs for trainings and provide a platform to deploy the trained AI models.
• GPT-4 has about 1.7 trillion parameters, or software knobs and dials used to make predictions.
• Despite being a much smaller model, the performance of Vicuna is remarkable.

Not all of these companies will use them all for a single training run, but those that do will have larger-scale models. Meta will have over 100,000 H100 chips by the end of this year, but a significant number of chips will be distributed in their data centers for inference. Instead, due to the lack of high-quality tokens, the dataset contains multiple epochs. Interestingly, this is far from being the best choice for Chinchilla, indicating the need to train the model with twice the number of tokens. The number of high-quality text tokens is 1,000 times that, while audio and visual tokens are even more, but obtaining them is not as simple as web scraping. The real challenge is the high cost of scaling these models for users and agents.

How do large language models work?

GPT-4 has 16 expert models, each with approximately 1.11 trillion parameters. Although the researchers were open about the computing resources used, and the techniques involved, they neglected to mention the timescales involved in training an LLM in this way. The scientists used a combination of tensor parallelism – groups of GPUs sharing the parts of the same tensor – as well as pipeline parallelism – groups of GPUs hosting neighboring components. They also employed data parallelism to consume a large number of tokens simultaneously and a larger amount of computing resources.

It’s safe to say that Llama 3 has upped the game, and by open-sourcing the model, Meta has closed the gap significantly between proprietary and open-source models. Fine-tuned models on Llama 3 70B would deliver exceptional performance. Apart from OpenAI, Anthropic, and Google, Meta has now officially joined the AI race. Following user instructions is very important for an AI model and Meta’s Llama 3 70B model excels at it.

Some AI models are “overparameterized.” Pruning the network to remove redundant parameters that do not affect a model’s performance could reduce computational costs and storage needed. The goal for AI developers is to find ways to reduce the number of parameters without sacrificing accuracy. Many experts and researchers are thinking about the energy and environmental costs of artificial intelligence and trying to make it greener.

It was released one year after GPT-2 — which was also released a year after the original GPT paper was published. If this trend were to hold across versions, GPT-4 should already be here. It’s not, but OpenAI’s CEO, Sam Altman, said a few months ago that GPT-4 is coming. Current estimates forecast the release date sometime in 2022, likely around July-August. A main difference between versions is that while GPT-3.5 is a text-to-text model, GPT-4 is more of a data-to-text model.

OpenAI also released an improved version of GPT-3, GPT-3.5, before officially launching GPT-4. It struggled with tasks that required more complex reasoning and understanding of context. While GPT-2 excelled at short paragraphs and snippets of text, it failed to maintain context and coherence over longer passages. An account with OpenAI is not the only way to access GPT-4 technology. Quora’s Poe Subscriptions is another service with GPT-4 behind it; the company is also working with Claude, the “helpful, honest, and harmless” AI chatbot competition from Anthropic. That caused server capacity problems, so it didn’t take long for OpenAI, the company behind it, to offer a paid version of the tech.

Compare this to the training of GPT-3 with 175 billion parameters, which consumed 1287 MWh of electricity, and resulted in carbon emissions of 502 metric tons of carbon dioxide equivalent. Inference energy consumption is high because while training is usually done multiple times to keep models current and optimized, inference is used many many times gpt 4 parameters to serve millions of users. The forthcoming language model of OpenAI, ChatGPT-4, might provide multimodal aptitudes and resolve ChatGPT’s sluggish answers to users’ questions. OpenAI might soon unveil the next generation of its large language model (LLM), ChatGPT-4, that might be able to produce AI-driven videos and other forms of content.

Other users were quick to share their experiences with GPT-4, with one commenting under the post that “the same call with the same data can take up to 4 times slower than 3.5 turbo.” In May 2020 OpenAI presented GPT-3 in a paper titled Language Models are Few Shot Learners. GPT-3, the largest neural network ever created, revolutionized the AI world.

Google is going even further than OpenAI and allowing access to Gemini 1.5 Pro at $7 per one million input tokens and $21 per one million output tokens (preview pricing) starting May 2, 2024. The input token pricing of Claude 3 Opus is $15 per one million input tokens (1.5x), and it costs more than twice as much as GPT-4 Turbo for output tokens—$75 per one million output tokens. Each standard is a litmus test designed to assess specific functions, such as reasoning, coding, etc. The problem is that companies can manipulate data or play with a prompt engineering technique to attain target benchmark points. Google and other AI companies have since made it clear that GenAI is at the top of their mind, having taken strategic measures and dedicated valuable capital.

• This timing is strategic, allowing the team to avoid the distractions of the American election cycle and to dedicate the necessary time for training and implementing safety measures.
• It is a standalone visual encoder separate from the text encoder, but with cross-attention.
• If an application needs to generate text with long attention contexts, the inference time will increase significantly.
• “When you apply LLMs to large datasets, or allow many people in parallel to run prompts … you’ll want to make sure you’re taking pricing into account,” he said.
• There is little information about the data used to train the system, the model size, the energy costs of the system, the hardware it runs on or the methods used to create it.

Training data plays a crucial role in the development of large language models. The quality and quantity of the training data can significantly impact the model’s capabilities and performance. Large language models rely on diverse and extensive datasets to learn the intricacies of human language. The better the training data, the more accurate and reliable the model’s outputs will be. This is why sourcing high-quality training data from various domains is essential for building effective language models. Next, we have the PaLM 2 AI model from Google, which is ranked among the best large language models of 2024.

Improving domain-specific language models can lead to lower healthcare costs, faster biological discovery, and better patient outcomes. Open AI has released relatively little information about the technical specifications of GPT-4. There is little information about the data used to train the system, the model size, the energy costs of the system, the hardware it runs on or the methods used to create it. OpenAI acknowledged this in the GPT-4 technical paper, which said they wouldn’t release this information because of safety reasons and the highly competitive market. OpenAI did acknowledge that GPT-4 was trained on both publicly available data and data licensed from third parties. The model exhibits human-level performance on many professional and academic benchmarks, including the Uniform Bar Exam.

For example, the model can return biased, inaccurate, or inappropriate responses. This issue arises because GPT-3 is trained on massive amounts of text that possibly contain biased and inaccurate information. There are also instances when the model generates totally irrelevant text to a prompt, indicating that the model still has difficulty understanding context and background knowledge. You can foun additiona information about ai customer service and artificial intelligence and NLP. GPT-3 is trained on a diverse range of data sources, including BookCorpus, Common Crawl, and Wikipedia, among others. The datasets comprise nearly a trillion words, allowing GPT-3 to generate sophisticated responses on a wide range of NLP tasks, even without providing any prior example data.

The search and cloud giant released Bard in March 2023 and rebranded it as Gemini just under a year later in February 2024. While Google managed to capture a portion of the market with the Gemini series of LLMs, it never quite has been able to usurp the best of what OpenAI has had to offer—currently, GPT 4 Turbo. With the NVLink Switch interconnect across 72 GPUs, those GPUs can talk incredibly fast to each other – and they can all talk to each other at the same time when necessary and complete that chatter fast.

We got a first look at the much-anticipated big new language model from OpenAI. Also, Images are increasingly tagged with ALT text as search engines favour sites that put work into being accessible. Apple has already put a lot of effort into Accessibility features to allow screen readers to do the same with Apps on their devices, giving them a wealth of text data at any time on the device to use for this. I guess this means they can “normalise” or even anonymise a query using on-device smarts and then feed it off to other AI systems on-line.
