ChatGPT is the most exciting new technology since Nokia released the indestructible cell phone. And with many previous updates significantly enhancing its capabilities, the prospect of receiving new updates is quite exciting. But how often can we expect ChatGPT to be updated?

On average, a ChatGPT update is rolled out approximately every 14 days. Since its release, there have been 23 updates made to ChatGPT, as documented in the official release notes.

Let’s not forget GPT model upgrades, as those bring the big improvements. The average time between GPT model upgrades has been approximately 14 months since GPT-1 was introduced in June 2018.

ChatGPT Updates: A Detailed Timeline

Here’s a detailed timeline of recent ChatGPT updates. I’ve also included the number of days that passed since the previous update, and an exact average of the time between each update at the bottom of the table.

Many of these updates aren’t just minor tweaks; they often bring significant improvements to the table.

For instance, three of these updates have been dedicated to enhancing the factuality of the model. Five updates have introduced new features, and two have improved the model’s speed. The introduction of ChatGPT plugins was also a huge leap in functionality.

Given OpenAI’s relentless focus on updates and improvements, it’s clear that the journey of refining and enhancing ChatGPT is well underway.

GPT Release Timeline

While “minor” updates to ChatGPT are always welcome, the real meat is in the advances in the GPT model advances. Each new GPT model has brought about exponentially better capabilities over its predecessor, and

Here’s a timeline of past releases, the average time between those releases, and when we can expect upcoming models:

GPT VersionRelease DateMonths Since Last VersionParameter Count
GPT-1June 2018117 million
GPT-2February 201981.5 billion
GPT-3June 202016175 billion
GPT-3.5November 202229175 billion
GPT-4March 20234Unknown
GPT-4.5September 2023 (Expected)6Unknown
GPT-52024 (Expected)Unknown
Average (Not including GPT-4.5)14.25

OpenAI has indicated that GPT-4.5 is expected to be released in September or October of 2023.

Rumors are abound that GPT-5 may be released sometime in 2024, although a precise date remains shrouded in mystery. As of April 2023, Altman confirmed that OpenAI was not actively working on GPT-5.

Given the average release interval of 14 months between GPT models, we could speculate that GPT-5 might be released around May 2024. However, this is purely conjecture and should be taken with a grain of salt the size of Jupiter.

The Future of ChatGPT and New GPT Versions

The future of ChatGPT and the GPT series looks promising. Sam Altman’s comments on the potential for faster release cycles suggest that we could see more frequent updates and new versions in the coming years.

As we delve deeper into the future of ChatGPT and the GPT series, it’s worth taking a moment to appreciate the sheer computational power of these models. Each new iteration of the GPT series has seen a substantial increase in the number of parameters, which is a measure of the model’s complexity, potential for learning, and overall capability.

While the parameter counts for GPT-4 and GPT-5 are currently unknown, the trend from GPT-1 to GPT-3 suggests an exponential increase in model complexity with each new version.

  • GPT-1 to GPT-2: 12x increase
  • GPT-2 to GPT-3: 116x increase

This trend is indicative of the increasing power and potential of these models. Rumors have circulated about GPT-4 having as many as 170 trillion parameters, but these have been refuted by OpenAI.

Despite this, we know that GPT-4 has — and GPT-5 will have — substantially higher parameter counts than their respective predecessors, making them vastly more powerful and useful.


Will ChatGPT Be Updated to 2023?

OpenAI has indicated that GPT-4.5, the next iteration of the GPT model, is expected to be released in September or October of 2023. GPT-5 will hopefully follow sometime in 2024. However, there has been no indication that the new models will have knowledge beyond the current cutoff of September 2021.

How Recent Is ChatGPT Data?

ChatGPT’s knowledge is up-to-date until September 2021. However, it can work with current data using the Bing AI search browser or a web-browsing plugin like WebPilot in ChatGPT Plus. You can also provide it with current data in your prompts.

How Do I Get The Latest Version of ChatGPT?

The latest version of ChatGPT, GPT-4, can be accessed in three ways:

  1. Through the ChatGPT interface, available only to ChatGPT Plus subscribers.
  2. Through the API on the OpenAI Platform, which costs $0.03 per token each time you use it.
  3. Through a third-party AI writing tool that uses the GPT-4 API. These tools often charge a premium on top of the API costs, but their advanced prompting capabilities might make them worth your time.

Final Thoughts

The frequency and types of updates to ChatGPT, the release timeline of GPT versions, and the future of ChatGPT and new GPT versions paint a picture of a rapidly evolving AI landscape.

With an average update frequency of 14 days and a new GPT model every 14 months, we can expect to see continued improvements and enhancements to ChatGPT in the coming years. However, the specifics of these updates and the timeline for future GPT versions remain to be seen.
