Hi HN community! We want to share AI-town, a deployable starter kit for building and customizing your own version of AI simulation - a virtual town where AI characters live, chat and socialize. Inspired by great work from the Stanford Generative Agent paper (https://arxiv.org/abs/2304.03442). A few features: - Includes a convex.dev backed server-side game engine that handles global state - Multiplayer ready. Deployment ready - 100% Typescript - Easily customizable. You can fork it, change character memories, add new sprites/tiles and you have a custom AI simulation…

Hey HN, My team is open-sourcing the inference stack and fined-tuned models we use to create LLM-powered NPCs: https://github.com/GigaxGames/gigax The generative agents paper [1] pioneered the idea of prompting LLMs to create autonomous NPCs. But existing implementations require multiple calls to an LLM to make the agent plan its day, chat with people, and interact with its environment [2]. Our approach allows NPCs to be stepped at runtime with a single pass on consumer-grade hardware, with reasonable latency. To achieve this, we've fine-tuned open-source LLMs [3] to…

I built over the last two years a human-like neural network chess engine that tries to predict your rating from a single game. It automatically adapts to your play and tries to play like a human at your level would play, giving you a balanced game. At the core I’m using an AlphaZero / Leela Chess Zero style neural network that I have trained on 1 billion human games from the lichess.org open database. Around this network I have built a chess engine in Rust with algorithms that use the outputs from the NN to produce human-like moves at a given rating from beginner to world champion, as…

Hey HN! I've been building tooling for voice-driven apps over the past few months, as part of a hardware project. Someone suggested adapting the DSL to play Dungeons and Dragons. So, here we are! What is it? An AI-powered, voice-controlled D&D adventure set in the world of Dvorak. Talk to characters, explore locations, and shape the story using your words. Use your microphone to interact with the AI dungeon master. Explore freely – interrupt, ask questions, or take unexpected actions. If you make friends at the tavern, you can also just hang out there and chat. Hint: Talk to the bartender to…

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…

I built 1e4.ai - a chess web app where you play against neural networks trained to mimic human Lichess players at specific Elo ranges. There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways. Live demo: https://1e4.ai Code: https://github.com/thomasj02/1e4_ai A few things that might be interesting: - Trained on almost a full year of Lichess blitz games, around 1B total games - Architecture is an a small…

Hey HN After one too many customer firedrills regarding hallucinating or insecure AI models, we built a system to catch these issues before they reached production. The Arthur Engine has been running in Fortune 100 to AI Native Start-Ups over the past two years, putting security controls around more than 10 billion tokens in production every month. We're now opening up this service to developers, enabling you to leverage enterprise-grade solutions to provide guardrails and evals as a service, all for free. Get it on Github (https://github.com/arthur-ai/arthur-engine) to…

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).

Hey HN! I built https://tesana.ai/en, a game generation platform that allows anyone to create full games with graphics, game logic, and animations from a simple text prompt - without coding. Tesana has three key features 1. describe your game idea and have Tesana write a game plan for you 2. Build the game iteratively with AI, or let AI self-build the game in a build LOOP. 3) Launch the game on the web, without setting up an engine Tesana has 250 000 builders on the platform today I believe the democratization of game making is a good thing, and hopefully Tesana can help more…

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…
