Lightwork
There's more AI news than anyone can possibly consume. Lightwork is the filter. Every Monday, Lightspeed's Claire Zau and Josh Machiz break down the one development that mattered most that week — a model release, a funding round, a company structural shift — and work through what changes because of it. They also bring in a guest working at the front of AI to sharpen the picture. By the end of each episode, you'll have a clearer view of where things are going and why it matters to you.
