A 400MB Qwen3-0.6B running on a 2017 Samsung Note 8 is driving a real desktop Chrome browser

An r/LocalLLaMA post from someone building the page-perception layer (145 upvotes, 20 comments) reports testing 12 small local models and finding that Qwen3-0.6B at 400MB, running on a nine-year-old Samsung Note 8, is enough to drive a real desktop Chrome session rather than a simulated one. The claim inverts the usual browser-agent assumption that page understanding needs a frontier VLM; if it holds, the cost floor for a browser agent is a phone that was mid-range in 2017. Single-source, from a party with a stake in the result, so treat the framing carefully.
