What happened
Perplexity has released a local AI agent called 'Portable Computer' for Windows that can perform multistep tasks, but it requires an RTX GPU with at least 24GB of VRAM, effectively limiting it to RTX 3090/4090-class cards. The article itself is mostly boilerplate with minimal technical detail beyond the hardware requirement.
Why it matters
The 24GB VRAM floor is the real signal: local agentic AI is arriving but the hardware bar is steep enough that most developer workstations won't qualify. If you're evaluating on-device agents for cost or privacy reasons, factor in that you likely need a 3090 or 4090, or you're waiting for model compression to catch up.
Discussion angle
Is the 24GB VRAM requirement a temporary ceiling or the new normal for local agents — and does that push Malaysian builders toward cloud APIs for agentic workflows rather than local inference?
