Since the release of ChatGPT last November, OpenAI hasn’t taken many L’s.

ChatGPT became the fastest-growing consumer app of all time, GPT-4 came out in March, OpenAI’s ARR hiked to $1.8B, and the company is now valued at a smooth $30B. That’s a miraculous turnaround for a business that only pulled in $28M in revenue in all of 2022.

But it hasn’t been all smooth sailing for OpenAI. It’s very expensive to train and operate AI models, in large part due to the AI chip demand surge they set off with ChatGPT. So, shortly after ChatGPT was released, OpenAI began training a new AI model designed to run the chatbot more efficiently.

That model was codenamed Arakis. The goal of Arakis was to use a concept known as sparsity to run more efficiently. Basically, instead of needing the whole model to answer prompts, sparsity enables the model to operate with just the parts of the model immediately needed. In theory, this leads to greater efficiency, and thus, lower costs and less need for chips.

It sounds great, except for one problem: it failed. And it failed for reasons that OpenAI still doesn’t understand. So they pivoted to developing a version of GPT-4 designed to generate responses quicker.

But that doesn’t mean sparsity isn’t a thing anymore. Many researchers still see it as the future of AI models.

And with advancements like Anthropic’s mechanistic interpretability breakthrough, it might not be too long until sparsity is a reality.

The Big Picture: With competition ramping up, OpenAI can’t afford too many more L’s.

Raise: Nuclear fusion company SHINE raised $70M.

Stat: $30,000: What Bitcoin reached following the Cointelegraph fake ETF fakeout. For those unware, Cointelegraph reported that a spot Bitcoin ETF was approved, which then led Bitcoin to shoot up to $30K just 10 minutes later. Unfortunately, it turns out that they prematurely shot the gun, and there’s no ETF yet. Still a very good sign for Bitcoin’s eventual resurgence.
