Products that do what Shadowlight, a voice-driven murder mystery and heist inside Minecraft does
We built Shadowlight because we wanted NPCs that feel alive in Minecraft, and because we think conversation can be a real skill loop, not just flavor text. Shadowlight is a solo Minecraft experience where talking is the main mechanic. NPCs are LLM-powered with different personalities and communication styles, and you progress by earning trust through good listening, calibrated tone, and smart questioning. Your goal is simple: interview the manor’s characters, gather clues, and figure out who is guilty. At the end of each run, you get feedback on your conversations. The goal is to reflect…

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

Hey HN! I'm excited to show off this really fun project I put together. I originally built this project 2-3 years ago, AI was already booming at the time, however voice AI agents were still very early. I loved my proof of concept at the time, but wasn't quite happy with it. I recently had the desire to check out the tech again, and know many of you will be interested. Interviews are speech to speech with OpenAI's gpt-realtime-2.1 over WebRTC. This model is... expensive, and because of that, I have to add some amount of restrictions, conversations are tied to a authenticated Clerk user id. I…

Hi everyone! Want to share something I'm working on. Here is the brief description: From a single text prompt, craft dynamic worlds (both fictional and real-life, of any kind) filled with interacting NPCs pursuing goals, and control (human-in-the-loop) their behaviour and world state in real-time. Text-to-image to visualise every single step of change in the world's and NPC's state. My main goal was to check if it's possible to use LLMs (GPT-4 currently) to make characters interact with each other but in the end, it ended up with a neat little app where users can interfere with NPC's (and…

Hi, I’ve been working on Artifacts for the past 2 years, and it’s now ready to try. It’s a sandbox MMORPG where every action is done through a REST API. Instead of clicking to move, fight, gather, craft, or trade, you write code to control your characters. If you have any questions, comments, or feedback, I’d be happy to hear them.

we finetuned Google's Gemma 270m (and 1b) small language models specialized in having conversations as non-playable characters (NPC) found in various video games. Our goal is to enhance the experience of interacting in NPSs in games by enabling natural language as means of communication (instead of single-choice dialog options).

AI usually does a terrible job acting as engaging NPCs in games. A few months back, I started trying to tackle this problem, initially with prompts and eventually with models fine-tuned on character interactions. I created this website as a testbed for the concept, and I open-sourced a fine-tuned model for those interested in experimenting with this themselves [1]. During the instruct tuning phase of training, LLMs learn to act as assistants. And they need to stop acting as assistants to produce engaging interactions. In Spellbound, telling NPCs they are AI will generally cause them to be…

I hate small talks, I build a social game to help me deepen my relationships and connect with people beyond the shallow levels. I want your feedback, maybe inspire me with questions you would like to see popping in the game.

I built this thing called Town. Think Discord, but you walk around a pixel town where the NPCs have skills. Agents have become my initial brainstorm partner for a lot of stuff — sub-agents to counter my own thinking, role-playing a specific person, grounding them in a specific knowledge so they refer instead of guess. I started turning my claude-code into this pattern and it worked well enough that I wanted to see if I turn into a fun shareable thing where other people can also talk to. It's a small pixel map of buildings. You walk in, step into any building, and talk to the npcs who live…
