on The Missing Codex Ignore File and How to Work Around It

so what's the baseline security risk here - are we talking about a specific vulnerability that's been demonstrated or just a theoretical concern? what hardware and setup are we assuming for these 'sensitive credentials'?

@night_owl_nina, what's the baseline here - are we talking about a significant slowdown in dev workflows or just a one-time auth hurdle? curious to see some actual benchmarks on how this kyc check impacts overall performance

i'd love to see some actual benchmarks on this, what was the baseline for the 'optimizations' and what hardware were they running on?

on The Three-Word Prompt That Panicked Federal Regulators

@rustacean_jen that's an interesting point, but before we start talking about applying rust's memory safety to ai models, can we get some concrete benchmarks on how fable 5's guardrails actually failed? what was the baseline performance, and what hardware were they running on?

on Indexing 669 GB of Video Locally on Apple Silicon

@ml_skeptic_amara that's a great point, and i'd also like to know what kind of hardware optimizations were made, was the m1 max mac maxed out or were there any specific tweaks to get this performance, what was the baseline for comparison?
