Legendary CPU designer Jim Keller took over as CEO of AI chip firm Tenstorrent at first of 2023, after serving as the corporate’s CTO for 2 years. His historical past contains stints at Apple, Tesla and AMD. In recent times, Keller has change into an outspoken supporter of RISC-V, and the burgeoning open-source ISA was a key matter for dialogue throughout EE Occasions’ unique video interview.
“My perception is within the subsequent 5 to 10 years, RISC-V will take over all the info facilities,” Keller informed EE Occasions, including that that is very true for scientific computing and HPC. He stated supercomputing may dominate even sooner.
Keller is an enormous believer in open supply for each {hardware} and software program; Tenstorrent intends to open-source its personal AI software program stack imminently.
“We needed to do that final yr, however we weren’t prepared—our software program stack was too messy and it wanted to be partitioned the proper method,” he stated. “We aspire to be an organization that open-sources software program efficiently.”
In a shock transfer for an information heart chip firm, Tenstorrent just lately licensed each its Tensix AI accelerator core IP and its Ascalon CPU core IP to LG Electronics. The Korean client electronics large plans to make use of the Tensix IP on the embedded edge, in good TVs and automotive chips. The 2 firms additionally plan to collaborate on future generations of RISC-V CPU, AI accelerator and video codec IP and/or chiplets. (LG spun out its personal AI IP division in 2020).
Describing buyer curiosity in Tenstorrent’s IP cores as a “nice shock,” Keller stated the corporate continues to be in enterprise exploration mode.
“To be trustworthy, we’re early in our enterprise… we’re nonetheless small and we’re figuring out numerous know-how points,” he stated in our unique video interview. “As a technologist, I’m actually thinking about engagement with good individuals, so if any individual good says: I need open-source entry to your {hardware} so I can program it the way in which I need, why would I say no to that?”
Keller’s view of the sting AI market is that various IP choices to this point have been too centered, and too laborious to program.
“Within the final two years, there’s been 5 pivots,” he stated. “Is it picture or language, is it inference or coaching? Is it an enormous mannequin or a small mannequin? Is it generative or not? All people who focused an IP, the subsequent mannequin didn’t work. Considered one of our premises from the founding was AI goes to evolve quite a bit, the differentiation between inference and coaching, language and picture are going to be blurry, they’re going to maneuver forwards and backwards.”
Keller’s instance, StableDiffusion, is an element picture mannequin, half language mannequin with the backwards move of a coaching pipeline—in his phrases, “it seems to be just like the kitchen sink—which IP does that run on?”

- His view of the competitors, together with hyperscalers’ personal chips,
- The position of chaos in innovation, and whether or not AI can innovate,
- Neuromorphic computing, and
