📝 Editorial 

Earlier this week I was at a dinner with some prominent VCs and I was asked my opinion about the balance of forces between the big AI labs. My answer was that I feel that, after the recent market events, OpenAI might have hit “escape velocity”. Celestial mechanics defines escape velocity as “speed needed to break free from the gravitational attraction of a massive body, without further propulsion”. In the venture capital space, the term is often used with companies that have achieved a growth momentum that can’t be stopped. Last week we devoted this editorial to the implications of strategic alliance between Microsoft and OpenAI. A few days ago, that alliance was cemented with Microsoft’s $10 billion investment in OpenAI’s recent tender offer. The capital, together with Microsoft’s infrastructure and distribution, might be last ingredient needed for OpenAI to catalyze a momentum that seems fundamentally stronger than other top players in the AI market.

ChatGPT has been at the center of OpenAI’s recent momentum. Initially planned as a demo of GPT-3.5 capabilities, the AI agent has taken the internet my storm challenging the imagination of creators, consumer and business application providers. ChatGPT is just a preview of what’s to come with GPT-4 which is rumored to have around 100 trillion parameters which is about 500x the size of GPT-3. The increase in size translates into a growth in capabilities that is far beyond exponential. Additionally, OpenAI is also taking leadership positions in areas such as text-to-image and text-to-code with models like DALL-E and Codex.

I certainly believe that the recent winds in the AI space have favored OpenAI but that doesn’t mean they will be the only company to capitalize on this momentum. In the current market, Google/DeepMind and Meta AI seems to be strongest alternative to OpenAI. Both tech giants have the research capabilities and compute infrastructures to compete with the Microsoft-OpenAI duo. Furthermore, both Google and Meta have been actively working in the generative AI space with models like LaMDA, Imagen, Muse, Make-A-Scene, Sparrow and many others.

Innovation in the foundation model space is happening everywhere but we might be on the verge of a race vastly dominated by OpenAI, Google and Meta. For now, OpenAI seems to have hit escape velocity.
