Odaily Planet Daily reported that Vitalik posted on X saying he is conducting a self-experiment. He plans to use his personal health and travel data to obtain personalized diet and exercise advice from advanced models, while avoiding leaking private information to remote models. A local model, Qwen 3.8 Flash Next, is responsible for coordinating, and a powerful remote model is used as a tool. The privacy solution includes having the local model write the queries, isolating payment identities via zkAPI, and isolating network and IP information through Tor.

Vitalik said the scheme has been running and has returned recommendations, but Tor is not suitable for disassociating per request, and the latency could be 10 to 100 times higher than the ideal level. The request-construction strategy is still not optimal: the current running speed of Qwen 3.8 Flash Next is about 20 to 30 TPS, and only when it reaches above 100 TPS will it become noticeably faster. He also said that the more cautiously you provide data to the remote model, the less help the remote model can provide.
