The most interesting AI Agent I've experienced recently comes from SIA NEXX.
This is an ecological platform focused on AI Agents. Compared to a single Agent, SIA NEXX is more like a diverse Agent store where users can find various Agents they are interested in to interact with.
Currently, there are 3 Agents online and available. According to the detailed points rules published by the official, engaging in dialogue training with these Agents can earn up to 250 points in a single day. This allows for a maximum of 5 interactions per day, with each interaction consisting of 5 rounds, and each valid round earning 50 points. (I tested some cheating methods, and the interaction generated by questions from ChatGPT and Deepseek was very interesting, using magic to defeat magic.)
For the dialogues with the Agents, you can also earn points through satisfaction or dissatisfaction ratings, with 10 points per rating and a maximum of 200 points per day.
By using the button in the upper right corner, you can submit your genuine feedback or suggestions about SIA (over 200 words) in one click; a valid submission will earn you 200 points. The limit for daily valid submissions for major critics is 10 times, totaling 2000 points. You can also earn a reward of 500 points for logging in continuously for 5 days (5 days/10 days/15 days... and so on).
For those interested, feel free to test it out for yourselves, and remember to connect your wallet and log in through your email first.
