Ever since the launch of ChatGPT in November 2022, the world has never been the same. The sensational chatbot brought out the insane capabilities of Artificial Intelligence to the fore. OpenAI which introduced ChatGPT based on its Large Language Model (LLM) GPT-3 went on to update the chatbot with its advanced version, the GPT-4.
While GPT-4 has endowed some incredible abilities to ChatGPT, there have been speculations around other models that the AI powerhouse has been working on. However, the Sam Altman-led company has been working clandestinely on most of its AI projects. Recently, it was reported that OpenAI has shelved its AI model that was named after the dystopian desert featured in the Hollywood sci-fi blockbuster ‘Dune’ – Arrakis.
What was Arakis AI?
The new AI model codenamed – Arakis AI, was expected to make AI inference cost-effective. Reportedly, OpenAI halted its development due to some quality constraints. The now-shelved AI model was expected to be as powerful as GPT-4, but cheaper when it came to deployment. This was because it was partly developed based on the sparse principle. The principal is essentially a neural network architecture that uses sparse representations of the input data to improve the efficiency and accuracy of the model. In simple words, only parts of a neural network are used to process input, unlike traditional models that are dense models with their entire neural network active.
Reportedly, OpenAI began developing Arrakis AI last fall and started training it sometime in the spring. According to reports, the team that was working on the model realised that the performance was not adequate. However, they worked on tweaking it for nearly a month. However, their attempts were futile, and eventually, the model was killed. Inexplicably, the sparse principle worked wonders in the early tests but failed on the larger model.
Although Arrakis AI is shut for now, OpenAI may use its work on the model in other upcoming models. It is learned that OpenAI later shifted its focus to models such as Vision and Gobi. Immediately after Arrakis failed, the researchers began working on updating GPT-4 into a version that is faster, possibly the GPT-4 version 0613.

It is to be noted that AI models that power ChatGPT are costly and resource-intensive. They require massive computing power from cloud providers like Google, Amazon, and Microsoft. According to a rough estimate, ChatGPT costs $7,00,000 to operate for a day.
Other models in the pipeline
Even though OpenAI is the undisputed leader in AI at the moment, the company is bracing itself for some stiff competition from Google which is working on its AI model Gemini. Google is reportedly planning to launch Gemini this fall, and OpenAI has already enabled text-to-image capabilities to ChatGPT by allowing access to Dall-E 3 to ChatGPT Plus users.
Meanwhile, there are murmurs about the new AI model codenamed Gobi that OpenAI is working on. Gobi is expected to be multimodal from the start. However, speculations are rife that Gobi could eventually be GPT-5.
