GPT-1 to GPT-4: Each of OpenAI’s GPT Models Explained and Compared
GPT-4 vs ChatGPT-3.5: Whats the Difference?
This chart assumes that due to the inability to fuse each operation, the memory bandwidth required for attention mechanism, and hardware overhead, the efficiency is equivalent to parameter reading. In reality, even with “optimized” libraries like Nvidia’s FasterTransformer, the total overhead is even greater. One of the reasons Nvidia is appreciated for its excellent software is that it constantly updates low-level software to improve the utilization of FLOPS by moving data more intelligently within and between chips and memory. Simply put, it only requires one attention head and can significantly reduce the memory usage of the KV cache.
Now, the company’s text-creation technology has leveled up to version 4, under the name GPT-4 (GPT stands for Generative Pre-trained Transformer, a name not even an Autobot would love). GPT-3 came out in 2020, and an improved version, GPT 3.5, was used to create ChatGPT. The launch of GPT-4 is much anticipated, with more excitable members of the AI community and Silicon Valley world already declaring it to be a huge leap forward. Sébastien Bubeck, a senior principal AI researcher at Microsoft Research, agrees. For him, the purpose of studying scaled-down AI is “about finding the minimal ingredients for the sparks of intelligence to emerge” from an algorithm.
Renewable energy use
GPT-4 shows improvements in reducing biases present in the training data. By addressing the issue of biases, the model could produce more fair and balanced outputs across different topics, demographics, and languages. A larger number of datasets will be needed for model training if more parameters are included in the model. That seems to imply that GPT-3.5 was trained using a large number of different datasets (almost the whole Wikipedia).

Don’t be surprised if the B100 and B200 have less than the full 192 GB of HBM3E capacity and 8 TB/sec of bandwidth when these devices are sold later this year. If Nvidia can ChatGPT get manufacturing yield and enough HBM3E memory, it is possible. The Pro model will be integrated into Google’s Bard, an online chatbot that was launched in March this year.
With a large number of parameters and the transformer model, LLMs are able to understand and generate accurate responses rapidly, which makes the AI technology broadly applicable across many different domains. Natural language processing models made exponential leaps with the release of GPT-3 in 2020. With 175 billion parameters, GPT-3 is over 100 times larger than GPT-1 and over ten times larger than GPT-2. OpenAI has made significant strides in natural language processing (NLP) through its GPT models. From GPT-1 to GPT-4, these models have been at the forefront of AI-generated content, from creating prose and poetry to chatbots and even coding. MIT Technology Review got a full brief on GPT-4 and said while it is “bigger and better,” no one can say precisely why.
This is not really a computation issue as much as it is an I/O and computation issue, Buck explained to us. With these Mixture of Expert modules, there are many more layers of parallelism and communication across and within those layers. There is the data parallelism – breaking the data set into chunks and dispatching parts of the calculation to each GPU – that is the hallmark of HPC and early AI computing.
Cost
Great annotation tools like Prodigy really help, but it still requires a lot of work involving one or several human resources on a potentially long period. In logical reasoning, mathematics, and creativity, PaLM 2 falls short of GPT-4. It also lags behind Anthropic’s Claude in a range of creative writing tasks. However, although it fails to live up to its billing as a GPT-4 killer, Google’s PaLM 2 remains a powerful language model in its own right, with immense capabilities.

OpenAI has a history of thorough testing and safety evaluations, as seen with GPT-4, which underwent three months of training. This meticulous approach suggests that the release of GPT-5 may still be some time away, as the team is committed to ensuring the highest standards of safety and functionality. His keynote presentation might have revealed (although by accident) that the largest AI model has a size of a staggering 1.8T (trillion) parameters. Google has announced four models based on PaLM 2 in different sizes (Gecko, Otter, Bison, and Unicorn).
Training Cost
Gemma is a family of open-source language models from Google that were trained on the same resources as Gemini. Gemma comes in two sizes — a 2 billion parameter model and a 7 billion parameter model. Gemma models can be run locally on a personal computer, and surpass similarly sized Llama 2 models on several evaluated benchmarks.
- GPT-2, launched in 2019, had 1.5 billion parameters; GPT-3 at 100 times larger, had 175 billion parameters; no one knows how large GPT-4 is.
- On average, GPT-3.5 exhibited a 9.4% and 1.6% higher accuracy in answering English questions than Polish ones for temperature parameters equal to 0 and 1 respectively.
- Despite its extensive neural network, it was unable to complete tasks requiring just intuition, something with which even humans struggle.
- Aside from interactive chart generation, ChatGPT Plus users still get early access to new features that OpenAI has rolled out, including the new ChatGPT desktop app for macOS, which is available now.
- The model’s performance is refined through tuning, adjusting the values for the parameters to find out which ones result in the most accurate and relevant outcomes.
A smaller model takes less time and resources to train and thus consumes less energy. The goal of a large language model is to guess what comes next in a body of text. Training involves exposing the model to huge amounts of data (possibly hundreds ChatGPT App of billions of words) which can come from the internet, books, articles, social media, and specialized datasets. Over time, the model figures out how to how to weigh different features of the data to accomplish the task it is given.
Today data centers run 24/7 and most derive their energy from fossil fuels, although there are increasing efforts to use renewable energy resources. Because of the energy the world’s data centers consume, they account for 2.5 to 3.7 percent of global greenhouse gas emissions, exceeding even those of the aviation industry. AI can help develop materials that are lighter and stronger, making wind turbines or aircraft lighter, which means they consume less energy. It can design new materials that use less resources, enhance battery storage, or improve carbon capture. AI can manage electricity from a variety of renewable energy sources, monitor energy consumption, and identify opportunities for increased efficiency in smart grids, power plants, supply chains, and manufacturing.

PaLM gets its name from a Google research initiative to build Pathways, ultimately creating a single model that serves as a foundation for multiple use cases. There are several fine-tuned versions of Palm, including Med-Palm 2 for life sciences and medical information as well as Sec-Palm for cybersecurity deployments to speed up threat analysis. GPT-4 demonstrated human-level performance in multiple academic exams.
Llama comes in smaller sizes that require less computing power to use, test and experiment with. This is why Google is so keen to highlight Gemini’s one million token context window. That’s up from 8,000 tokens for the original Llama 3 8B and 70B releases. You can think of an LLM’s context window a bit like its short-term memory.
The critical methods of deep learning utilized by the model consist of directed learning and support learning from human feedback. It utilizes the formerly entered retorts from the user to create its next response. ChatGPT and GPT3.5 were supposed to be qualified on an Azure AI supercomputing Infrastructure. It will include multimodal language models that can collect information from a wide range of sources. The latest developments based on GPT-4 might be able to answer consumer questions in the form of images and music.
Expanded use of techniques such as reinforcement learning from human feedback, which OpenAI uses to train ChatGPT, could help improve the accuracy of LLMs too. There may be several potential reasons for the imperfect performance and providing incorrect answers by the tested models. First of all, both models are general-purpose LLMs that are capable of answering questions from various fields and are not dedicated to medical applications. This problem can be addressed by fine-tuning the models, that is, further training them in terms of medical education. As was shown in other studies, a finetuning of LLMs can further increase the accuracy in terms of answering medical questions32,33,34.
Apple AI research reveals a model that will make giving commands to Siri faster and more efficient by converting any given context into text, which is easier to parse by a Large Language Model. “We show that ReaLM outperforms previous approaches, and performs roughly as well as the state of the art LLM today, GPT-4, despite consisting of far fewer parameters,” the paper states. The new o1-preview model, and its o1-mini counterpart, are already available for use and evaluation, here’s how to get access for yourself.
Number of Parameters in GPT-4 (Latest Data)
However, in today’s conditions, with a cost of 2 USD per H100 GPU hour, pre-training can be done on approximately 8,192 H100 GPUs in just 55 days, at a cost of 21.5 million USD. If the cost of OpenAI’s cloud computing is approximately 1 USD per A100 GPU hour, then under these conditions, the cost of this training session alone is approximately 63 million USD. OpenAI trained GPT-4 with approximately 2.15e25 FLOPS, using around 25,000 A100 GPUs for 90 to 100 days, with a utilization rate between 32% and 36%. The high number of failures is also a reason for the low utilization rate, which requires restarting training from previous checkpoints.
And now we have model parallelism as we have a mixture of experts who do their training and inference so we can see which one is the best at giving this kind of answer. Unlike the others, its parameter count has not been released to the public, though there are rumors that the model has more than 170 trillion. OpenAI describes GPT-4 as a multimodal model, meaning it can process and generate both language and images as opposed to being limited to only language. GPT-4 also introduced a system message, which lets users specify tone of voice and task. They do natural language processing and influence the architecture of future models.
In an MoE model, a gating network determines the weight of each expert’s output based on the input. This allows different experts to specialize in different parts of the input space. This architecture is particularly useful for large and complex data sets, as it can effectively partition the problem space into simpler subspaces. Microsoft is working on a new large-scale AI language model called MAI-1, which could potentially rival gpt 4 parameters state-of-the-art models from Google, Anthropic, and OpenAI, according to a report by The Information. This marks the first time Microsoft has developed an in-house AI model of this magnitude since investing over $10 billion in OpenAI for the rights to reuse the startup’s AI models. AI companies have ceased to disclose the parameter count, the fundamental blocks of LLMs that get adjusted and readjusted as the models are trained.
- Theoretically, considering data communication and computation time, 15 pipelines are quite a lot.
- Good multimodal models are considerably difficult to develop as compared to good language-only models as multimodal models need to be able to properly bind textual and visual data into a single depiction.
- Best of all, you get a GUI installer where you can select a model and start using it right away.
- By approaching these big questions with smaller models, Bubeck hopes to improve AI in as economical a way as possible.
- ChatGPT has been developed in addition to the GPT-3.5 of OpenAI which is an advanced version of GPT 3.
- Eli Collins at Google DeepMind says Gemini is the company’s largest and most capable model, but also its most general – meaning it is adaptable to a variety of tasks.
GPT-2, launched in 2019, had 1.5 billion parameters; GPT-3 at 100 times larger, had 175 billion parameters; no one knows how large GPT-4 is. Google’s PaLM large language model, which is much more powerful than Bard, had 540 billion parameters. ChatGPT has been developed in addition to the GPT-3.5 of OpenAI which is an advanced version of GPT 3. The GPT 3.5 is an autoregressive language model that utilizes deep learning to create human-like text.
