OpenAI are halving the effective Astra usage of their $200/month plan (and adding a $500/month plan that gives you what you used to have). I assume the regular resets will stop too. A lot of people aren’t happy and say they’re cancelling. Doesn’t bode well for OpenAI.

When OpenAI announces they're halving the usage on your 20x plan on the same day that bond yields hit their 20 year high

I cancelled my Anthropic sub over this, so looks like it's time to reconsider my OpenAI sub too.

I've seen a lot of people sniffing out deepfake scammers on video calls (fake job interviews etc) by asking them to hold their hand or their fingers in front of their face. That hack won't last long though, so I don't know what people are going to do next.

My recent contributions to the Dart SDK have landed, adding support for importing multiple and/or shared WebAssembly memories. Getting closer to "native" interop between Dart and external WASM libraries (rather than hacky JS bridges). github.com/dart-lang/sd... github.com/dart-lang/sd...

Back-of-the-envelope calculation for "super-intelligent AGI can self-replicate over airgapped machines via CPU thermal signalling". BitWhisper did this, maxing out at 8 bits per hour, but let's be generous and assume 100x improvement in future hardware/sensors, so 800 bits / hour.

Sales from the Holotype website are starting to trickle in, which is great to see. Advantage is I only pay Stripe fees, no commission Gumroad takes 10% (with a caveat), Superhive is 30% BEFORE merchant fee & Blender fund contribution which is...a lot.

My experience with a Nous Research sub wasn't terrible, but it wasn't great either: 1) servers were down regularly, unfortunately the least reliable service I've tried 2) no option to remove credit card after cancelling sub 3) e-mail support about removing CC, still no reply after 2 days

Precisely this. I don't see the point in wringing our hands about risks like "super-intelligent AI engineers biovirus" until we've at least properly planned for the more mundane, but much more realistic risk, of dumb models doing dumb things in poorly secured environments.

Obviously retaining healthy skepticism until I see this in action, but this looks like a great fit for the coding harness I've been (vibe)coding in the background. One orchestrator + a swarm of fast-but-dumb "classification" agents giving simple yes/no questions for a small unit of the codebase.

I came across TopoRig today (a paper/repository for facial rig prediction), and took their implementation for a spin via the HuggingFace space. It's no easy task! The eyes/lips are almost always the problem, a single misplaced vertex visibly wrecks the whole result.

I'm sure this was well-intentioned, but "it's a race to the nuclear bomb and the communists need to win" is quite possibly the worst conceivable way to present this argument.

“we cannot rule out that de-identified data derived from their usage of our products helped improve our models.” It should be easy to check if Tristan’s conversations were ingested as training data. The fact that they’re not screaming that it wasn’t probably tells you everything you need to know.

My experience with Astra so far is that it's a definite step up from Sol (particularly for vision & 3D tasks), and it's really great at finding bugs in large codebases, but it still regularly makes some truly bizarre coding choices like this:
