The Transition from OpenAI to Thinking Machines

Mira Murati, who served as the CTO of OpenAI, took a significant risk by leaving a well-established company. Her departure was not a result of a fully formed plan but rather a vague idea to create a space for her research. This bold move involved the greatest talent heist in Silicon Valley history, as she brought along a co-founder and a team of top researchers. This new collective goal was to create Thinking Machines, a company focused on developing AI models with a strong emphasis on honesty and transparency.

The Launch of Inklink

The flagship product of Thinking Machines is Inklink, an AI model with 975 billion parameters. This model is trained on a diverse range of data, including text, images, sound, and video. Unlike many AI models, Inklink is designed to be open, available for anyone to download and use. This open approach aligns with the broader philosophy of Thinking Machines, which emphasizes transparency and honesty.

The Valuation and Market Impact

Thinking Machines' $12 billion valuation, despite having no initial product, underscores the market's high regard for innovative research and talent. This valuation reflects how the tech industry values not just products but also the potential and vision of the teams behind them.

The success of Thinking Machines in attracting top talent and achieving a high valuation highlights the importance of strong leadership and innovative ideas in the AI sector. This decision to prioritize transparency and honest AI development is a refreshing shift from the competitive and often opaque nature of the tech market.

Emphasis on Honesty in AI

One of the standout features of Inklink is its emphasis on honesty. The developers at Thinking Machines have been transparent about the limitations of their model, openly admitting that it is not the best performer in the world. This honesty is a deliberate design choice. Training the model to be honest reflects a broader commitment to ethical AI development.
