The Obtain: AI brokers’ autonomy, and sodium-based batteries

In current months, a brand new class of brokers has arrived on the scene: ones constructed utilizing massive language fashions. Any motion that may be captured by textual content—from taking part in a online game utilizing written instructions to operating a social media account—is probably inside the purview of one of these system.

LLM brokers don’t have a lot of a monitor report but, however to listen to CEOs inform it, they may rework the economic system—and shortly. Regardless of that, like chatbot LLMs, brokers could be chaotic and unpredictable. Right here’s what may occur as we attempt to combine them into every part.

These new batteries are discovering a distinct segment

Lithium-ion batteries have some rising competitors: Sodium-based options.

Sodium is extra ample on Earth than lithium, and batteries that use the fabric may very well be cheaper sooner or later. Constructing a brand new battery chemistry is tough, largely as a result of lithium is so entrenched. However, as I’ve famous earlier than, this new know-how has some benefits in nooks and crannies.

I’ve been following sodium-ion batteries for a number of years, and we’re beginning to see the chemistry make progress. Let’s discuss what’s new for sodium batteries, and what it’ll take for them to essentially escape.
