On March 15, 2022, OpenAI made available new versions of GPT-3 and Codex in its API with edit and insert capabilities under the names "text-davinci-002" and "code-davinci-002".[29] These models were described as more capable than previous versions and were trained on data up to June 2021.[30] On November 28, 2022, OpenAI introduced text-davinci-003.[31] On November 30, 2022, OpenAI began referring to these models as belonging to the "GPT-3.5" series,[30] and released ChatGPT, which was fine-tuned from a model in the GPT-3.5 series.[32] OpenAI does not include GPT-3.5 in GPT-3.[33]

To enable browsing capabilities, OpenAI implemented a new API that allows the GPT-3.5 with Browsing (ALPHA) model to access selected online resources during operation.[37] This feature allows users to ask questions or request information with the expectation that the model will deliver updated, accurate, and relevant answers based on the latest online sources available to it.
But with a standardized endpoint now available to everyone else, the playing field has leveled. You don't need to be a deployment/operations professional to get value out of Stable Diffusion anymore (nor do you need access to expensive GPUs).
22. ChatGPT's performance is also influenced by the amount of training data it has been exposed to. The more data a language model has been trained on, the more information it has available to generate accurate and relevant responses.
What types of AI models are available in OpenAI Playground?OpenAI Playground provides a variety of pre-built AI models like GPT-3 and GPT-4 that can perform tasks such as image classification, text generation, and sentiment analysis.
The latest OpenAI API, which includes GPT-3 and is now readily available, contains a host of safety improvements, including Instruct Series models that adhere better to human instructions, specialized endpoints for more truthful question-answering, and a free content filter to help developers mitigate accidental abuse.
A Generative Pre-Trained Transformer (GPT) is a sophisticated neural network architecture used to train large language models (LLMs). It makes use of large amounts of publicly available Internet text to simulate human communication.
At Cerebras, we believe in fostering open access to the most advanced models. With this in mind, we are proud to announce the release to the open source community of Cerebras-GPT, a family of seven GPT models ranging from 111 million to 13 billion parameters. Trained using the Chinchilla formula, these models provide the highest accuracy for a given compute budget. Cerebras-GPT has faster training times, lower training costs, and consumes less energy than any publicly available model to date.
We trained all Cerebras-GPT models on a 16x CS-2 Cerebras Wafer-Scale Cluster called Andromeda. The cluster enabled all experiments to be completed quickly, without the traditional distributed systems engineering and model parallel tuning needed on GPU clusters. Most importantly, it enabled our researchers to focus on the design of the ML instead of the distributed system. We believe the capability to easily train large models is a key enabler for the broad community, so we have made the Cerebras Wafer-Scale Cluster available on the cloud through the Cerebras AI Model Studio.
Tokens are essentially short sequences of a few characters. They correspond to words or parts of words. The best way to get an intuition for tokens is to try out tokenization with publicly available online tokenizers (e.g., OpenAI). For GPT-3, the average length of a token is 4 characters.
Price: The table below shows pricing for a number of major and smaller specialty clouds as of April 7, 2023. This data is only indicative, as the instances vary considerably in terms of network bandwidth, data egress costs, additional cost from CPU and network, available discounts, and other factors. For example, Google requires an A2 accelerated-optimized instance for an A100 40GB, which can increase cost by 25%.
Some techniques work with a fairly broad range of models. Using shorter floating point representations (i.e., FP16 or FP8 vs. the original FP32) or quantization (INT8, INT4, INT2) achieve a speedup that is often linear with the reduction of bits. This sometimes requires modifying the model, but there are, increasingly, technologies available that automate working with mixed or shorter precision. Pruning neural networks reduces the number of weights by ignoring weights with low values. Together with efficient sparse matrix multiplication, this can achieve a substantial speedup on modern GPUs. Another set of optimization techniques addresses the memory bandwidth bottleneck (e.g., by streaming model weights).

You can adapt the Python example to other languages, but you may not have an OpenAI library available. This is not a problem, because the OpenAI API is a fairly standard HTTP API that you can access through raw HTTP requests.
After many months of anticipation, OpenAI has finally launched an official iOS app that you can go and download today. The app quickly topped half a million downloads in less than a week and is becoming available in an increasing number of countries.
Since then, OpenAI has stated that GPT-5 is not on the timeline and is not currently planned. That being said, the next version, GPT-4.5, is currently training and may be available later this year. OpenAI indicated that it may be done planning as early as September or October.
Microsoft has officially brought ChatGPT to Bing in the form of Bing Chat. After a long beta period, it was officially available to try out. But unlike ChatGPT, Bing Chat does require downloading the latest version of Edge. So Safari or Chrome users are out of luck.
ChatGPT is available via a webpage, so no downloading is needed. However, OpenAI has finally released a free, official iOS app that needs to be downloaded from the iOS app store. For many months, the various app stores were full of fake versions. These are still out there, though, and should be installed and used with caution, as they are not official ChatGPT apps. There is no still no official Android app.
Regardless, the results are a fairly dramatic difference between GPT-3.5 and GPT-4 in terms of quality. It offers much more precise answers, is significantly better at coding and creative collaboration, and can provide (and respond to) much longer selections of text. GPT-4 remains the best possible model available, while GPT-3.5 is more in line with some other models available.
But models like OpenAI's GPT-3 or Google's LaMDA are well-kept secrets, their code isn't freely available. Independent researchers have therefore been working for several years on open-source alternatives to open up usage and research access to large-scale language models.
Now there is a true open-source alternative to GPT-3, BigScience Bloom, which is freely available for research and enterprise purposes. Bloom was trained over 117 days at the supercomputing center of the French National Center for Scientific Research and is 176 billion parameters in size.
The release falls under the Responsible AI License developed by BigScience, which prohibits the use of Bloom in areas such as law enforcement, healthcare, or deception. However, unlike OpenAI, for example, BigScience has no way to effectively prevent misuse because the model is available directly and not through an interface.
