Recently, miHoYo is going to create a new game called "Xingbu Valley", where the entire world's NPCs, missions, and dialogues are all generated by AI. The meaning is that whatever you do or say to NPCs, they will remember, their emotions will change, and even their attitudes will change because of a single word you say. To be honest, this is no longer the traditional 'silly NPC', it's really like putting a 'brain' on a virtual character. It is precisely because of this trend that I have recently noticed a project that is very similar to, and even more radical than, this direction - @ EPHYRA_SAI The goal of EPHYRA is simple but crazy: It's not about being an AI that makes chatting smarter, but about making digital characters truly emotional, memorable, and motivated, growing up in the virtual world like small life forms. They developed their own cognitive architecture called ECA, which essentially involves doing "three things" for the characters: Remember you: both short-term memory and long-term events will be recorded Feel you: happy, hesitant, angry Evaluate you: Trust you or be wary of you, it depends on how you treated it before So if you interact with it for a long time, it will really 'change'. You praise it, it's in a good mood; If you say two words to it, it will cold you; Your long-term companionship will gradually warm up its attitude. Their previous test data was also quite interesting: over 6000 people participated, with an average chat time of 20 minutes and a follow-up rate of over 60%. It shows that everyone is really willing to chat with this "semi alive" character. EPHYRA's current ecology is also very open: There is an early training activity called Genesis; VIP Pass with long-term benefits (the highest level has been sold out); There is a staking system, with a maximum reward of 1.7x for 12 months; This year, Ephyra Companion will also be launched, which should be the most immersive part of 'virtual life growth'. If you are interested in AI NPCs, virtual companions, and digital life, EPHYRA is really worth following. It's not doing 'chatbot 2.0', but trying to answer a more futuristic question: Can the virtual world also grow its own life?
