It's Not the GPUs: What's Really Holding AI Models Back

Everyone assumes GPU compute is the limiting factor in AI development — but the real constraint runs much deeper. Memory bandwidth, data movement, and architectural inefficiencies are quietly throttling model performance in ways raw processing power can't fix.

Nine AI Tools Can Be Weaponized Into Botnets via Prompts

Researchers have found that nine of the most widely used AI tools are vulnerable to a new class of prompt injection attack capable of assembling large-scale botnets. Unlike traditional targeted injections, these 'pull' attacks require no direct contact with victims — dramatically expanding the threat surface. Here's what you need to know.
