Azure OpenAI ChatGPT Legacy Training April 2023 Dynamics Edge
The Free version of ChatGPT

ChatGPT Free

ChatGPT Free can be accessed on chat.openai.com and is a pre-trained version of the model that is available for free. This version of ChatGPT cannot be accessed through an API or integrated into other applications. This version cannot be accessed via Azure as well. However, it can be used to ask questions and receive answers in a number of areas (i.e. we noticed it can at least attempt to answer questions in pretty much any area, actually), to the best of ChatGPT’s abilities.

It’s important to note that the speed and quality of the response may be limited compared to the paid version, and there may be service outages and availability issues during times of high demand. Additionally, there may be strict limits on the number of messages that can be sent per hour.

The user interface that shows multiple options between Default (GPT-3.5) Legacy (GPT-3.5) and GPT-4 is also only available for accounts that have a ChatGPT+ Subscription active.

The one that the Free version is using is likely either the Legacy (GPT-3.5) – or, it may even be a less capable one reserved for free users.

You cannot select from multiple options in the Free version, it’s likely using a reduced version of ChatGPT that’s for the Free level specifically, both in how much you are allowed to use it and potentially the level of quality of the output – it may be a free level that isn’t even as capabale as the Legacy (GPT-3.5) version, let alone the Default (GPt-3.5) version.

In other words, to get a good introduction to ChatGPT’s capabilities, you may want a paid, active ChatGPT+ subscription to begin with.

ChatGPT Plus

ChatGPT Plus is a paid subscription service that provides access to a higher-performance version of the ChatGPT model. Compared to the free version, the response speed and quality is likely to be better, and the availability is more reliable. We noticed the speed was much faster, and the quality of the responses were also better, in the paid version compared to the free version. While some may suggest it may be only the speed, we noticed that the quality, and not just the speed, might also be actually better on the paid version, and not just the speed.

As of March and April 2023, ChatGPT 4 is available on chat.openai.com for users with an active ChatGPT Plus subscription.

ChatGPT 4

ChatGPT-4 is a more advanced version of the ChatGPT model and is only available in the ChatGPT+ subscription, not in the free chat.openai.com account. This model has a larger capacity and has been trained on more data than the standard ChatGPT model, making it more powerful and capable of generating more diverse and nuanced responses.

ChatGPT-4 also has more advanced capabilities, such as the ability to hold longer-term context, understand more complex topics, and generate more creative responses. However, due to its increased capacity and capabilities, it may also require more computational resources and may take longer to generate responses compared to the standard ChatGPT model.

Overall, ChatGPT-4 is a more advanced and powerful version of the ChatGPT model, but it is only available through the ChatGPT+ subscription and may require more resources to use effectively.

It’s important to note that ChatGPT 4 is only available to subscribers of the ChatGPT+ service and is not accessible through the free chat.openai.com account.

Additionally, there may be strict limits on the usage of ChatGPT 4 due to high demand and computational resources. For example, there may be a limit of 25 messages per 3 hours for ChatGPT 4. These limits may be subject to change as well, and they may become even more strict in the future as it may be adjusted for demand.

Can I always buy a ChatGPT+  subscription?

Actually, no, you might not be able to always buy a subscription. It’s important to note that even ChatGPT Plus subscriptions themselves may not be available for upgrade on your free ChatGPT account at all times, due to such a high demand for ChatGPT+. If this happens, only accounts that already have an active subscription can use ChatGPT+, and ChatGPT accounts that are still on the free level of ChatGPT cannot upgrade even if you are willing and ready to pay for it. In that case, you may have to use only the free version, even if you are ready and willing to pay, until, if, and when ChatGPT+ becomes available again. If, when, and once you notice that it becomes available again, it’s recommended to upgrade as soon as possible, as it may become unavailable again at any time, with no guarantee of it becoming available again in the future.

Therefore, it’s recommended to consider purchasing a subscription as soon as possible and while they are available, if possible.

You may purchase a subscription directly from OpenAI by going to chat,openai.com and making a free account first you don’t already have one, logging in, and then once on chat.openai.com logged in, clicking on Upgrade to Plus – which to our knowledge as of April 2023, is only costing about $20 per month.

If it doesn’t let you buy it, you may have to wait until they let you buy it. Or you may contact Dynamics Edge for more information.

Note that even to make a free account on chat.openai.com, you may need a valid, non-VOIP phone number to verify your account.


Do I have Unlimited Access to ChatGPT 3.5 with ChatGPT+ ?

No, there’s no “unlimited” access even with a paid and active ChatGPT+ subscription. While the hourly limit seems to be far more lenient with a paid subscription compared to the free level, and while the limits are usually much more strict just with ChatGPT4 in particular rather than ChatGPT 3.5 in the paid version, there are still some kinds of limits, including possibly hourly limits, which we may have occasionally seen and even hit, actually. We do not know the exact number of message or exact factors that may trigger a limit in the paid version when using the Default (GPT-3.5), and even if we did, this may be subject to change. If you trigger a limit, you’ll have to wait and come back later. You are not granted unlimited access or unlimited messages, even with a paid subscription.

Also note that chat.openai.com, even a ChatGPT+ subscription does not provide any access via API or via Azure.


Below is some introductory information on Azure OpenAI Service, but for more comprehensive options such as Azure ChatGPT Training contact Dynamics Edge for more details.

Azure OpenAI Service

Azure OpenAI Service is a cloud-based service that combines the computing resources of Microsoft Azure with the AI technologies of OpenAI. The service provides a range of AI models and tools, including ChatGPT, which can be accessed through a set of APIs and SDKs. It’s important to note that the usage of ChatGPT on the Azure OpenAI Service may require a case-by-case approval by Microsoft and may not be available to the public. Contact Dynamics Edge for more information on this. ChatGPT on Azure OpenAI Service is designed for enterprise use cases and is typically used by organizations to build custom AI applications and services.

Compared to other options, Azure OpenAI Service may provide more flexibility and customization options, but also may require more technical expertise and is geared towards enterprise use cases.

Other ways to access ChatGPT

There are two main alternative ways to access ChatGPT, and both of them are neither on chat.openai.com nor Azure – they are via OpenAI directly, and they are via the Text Completions API and the Chat Completions API.

These use a prepaid token model of billing, where you buy a package of tokens from OpenAI, and the tokens are consumed from your balance as you use the API’s. Both inputs and outputs are counted and billed for token metering. A “token” is a specific unit of measurement, and the total number of “tokens” a string is can be somewhat, loosely associated on how long your input is and how long ChatGPT’s output is, but there’s some technical details to that in order to be more correct and accurate on that, which we won’t go into for now, you can ask us for more info.

While both the Text Completions API and the Chat Completions API APIs offer similar functionality, there are some differences to keep in mind.

The Text Completions API is designed for completing text-based prompts, such as generating natural language responses to prompts or generating content for creative writing. However, it may not be as suitable for conversational contexts because it may lack the ability to maintain a consistent dialogue flow with the user, as the API is designed specifically for “completions”, not for “chat”. It may have some limitations on the maximum number of tokens or characters that can be generated in a single completion, which could affect its suitability for certain use cases.

The Chat Completions API, on the other hand, is specifically designed for generating responses in a conversational context. It can be used to generate chatbot responses or to train models to simulate human-like conversation. However, it may also have token limits or other limitations that could affect its suitability for certain use cases.

Completions versus Chat

The main difference between completions and chat is the context in which they are used. The Text Completions API is typically used for tasks that require generating a single text-based output based on a given prompt, such as generating natural language responses or creative writing.

In contrast, Chat Completions API is designed specifically for conversational contexts, where the model needs to maintain a consistent dialogue flow with the user, understanding the context of the conversation and generating relevant responses that build on the previous conversational turns.

In essence, completions are focused on generating a single, coherent response to a given prompt, while chat is focused on generating a sequence of responses that build upon each other to create a natural and engaging conversation between the model and the user. While both APIs share some similarities in terms of the technology and models used, they are optimized for different use cases and have different capabilities and limitations. For example, Chat Completions API may be better suited for applications that require maintaining a natural conversation with the user, whereas Text Completions API may be more appropriate for generating standalone pieces of text.

Chat Completions API may not be a substitute for Azure OpenAI Service

It’s worth noting that both APIs may have different levels of flexibility, customization, or access to ChatGPT compared to something like the Azure OpenAI Service.

While the Text Completions API and the Chat Completions API both offer additional ways to access ChatGPT, they may not be as suitable as something like the Azure OpenAI Service for certain use cases, such as providing ChatGPT with large amounts of text or answering questions based on large amounts of instructions. It’s important to keep in mind the potential limitations and differences between these APIs when considering which one to use for a particular project.

Additionally, the models accessed by these APIs may or may not be exactly the same ones or as comprehensive as the ones available on Azure OpenAI Service. Note that public information on the technology may be limited. and even actual methods on how the technology works may be subject to change and no information in this article is guaranteed to be accurate, or even if it is, it may no longer be accurate tomorrow.
