A16z Eyes Major Investment in Thinking Machines Lab

Mira Murati, the former CTO of OpenAI, has attracted significant attention from venture capital firm Andreessen Horowitz (A16z) for her new startup, Thinking Machines Lab. According to sources, A16z is in discussions to lead a substantial early-stage funding round that could value the startup at $10 billion, despite its recent launch in February and lack of revenue or products.

Thinking Machines Lab aims to develop safer and more reliable artificial intelligence systems with broader applications than its competitors. The startup has already assembled a team of around 30 leading AI researchers and engineers, many of whom are former OpenAI employees. This move underscores Murati's ability to attract top talent from her previous employer.

In addition to A16z, Sequoia Capital is also reportedly interested in participating in the funding round, which could total up to $2 billion. This interest highlights the ongoing enthusiasm among investors for new AI ventures, even as questions about tech industry spending persist. A16z is concurrently raising a $20 billion megafund dedicated to later-stage AI investments, which would be the largest in the firm's history.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
