This week's flight of the New Shepard spacecraft, NS-31, and its all-female crew has stirred up a mess of coverage, from tabloids to high-brow journalism outlets. And why not? Six women, led by superstar Katy Perry, were flying into space!

By contrast, Ars Technica has been largely silent. Why? Because yet another suborbital flight on New Shepard matters little in the long arc of spaceflight history. Beyond that, I did not want to be too negative about someone else's happiness, especially since it was privately funded. Live and let live, and all of that.

However, if I'm being frank, this flight and its breathless promotion made me uncomfortable. Let me explain. Perhaps the most important change in spaceflight over the last two decades has been the rise of commercial spaceflight, which is bringing down the cost of access to space and marks an essential step to humanity becoming a spacefaring species. This rising tide has been spurred in large part by billionaires, particularly Elon Musk, Jeff Bezos, and, to a lesser extent, Richard Branson.

When it comes to actually storing the numerical weights that power a large language model's underlying neural network , most modern AI models rely on the precision of 16- or 32-bit floating point numbers . But that level of precision can come at the cost of large memory footprints (in the hundreds of gigabytes for the largest models) and significant processing resources needed for the complex matrix multiplication used when responding to prompts.

Now, researchers at Microsoft's General Artificial Intelligence group have released a new neural network model that works with just three distinct weight values: -1, 0, or 1. Building on top of previous work Microsoft Research published in 2023 , the new model's "ternary" architecture reduces overall complexity and "substantial advantages in computational efficiency," the researchers write, allowing it to run effectively on a simple desktop CPU . And despite the massive reduction in weight precision, the researchers claim that the model "can achieve performance comparable to leading open-weight, full-precision models of similar size across a wide range of tasks."

Watching your weights

The idea of simplifying model weights isn't a completely new one in AI research. For years, researchers have been experimenting with quantization techniques that squeeze their neural network weights into smaller memory envelopes. In recent years, the most extreme quantization efforts have focused on so-called "BitNets" that represent each weight in a single bit (representing +1 or -1).

Popular NAS-maker Synology has confirmed and slightly clarified a policy that appeared on its German website earlier this week: Its "Plus" tier of devices , starting with the 2025 series, will require Synology-branded hard drives for full compatibility, at least at first.

"Synology-branded drives will be needed for use in the newly announced Plus series, with plans to update the Product Compatibility List as additional drives can be thoroughly vetted in Synology systems," a Synology representative told Ars by email. "Extensive internal testing has shown that drives that follow a rigorous validation process when paired with Synology systems are at less risk of drive failure and ongoing compatibility issues."

Without a Synology-branded or approved drive in a device that requires it, NAS devices could fail to create storage pools and lose volume-wide deduplication and lifespan analysis, Synology's German press release stated . Similar drive restrictions are already in place for XS Plus and rack-mounted Synology models, though work-arounds exist.
