I built Scene Palette to pick colors for my games. Drop in an image, generate a palette, preview it on a live UI, and export CSS, Godot, JSON & more. Free, open source, and in beta. I'd love feedback, especially bug reports. mythicruntime-lab.github.io/…

The $200 Claude Ultra plan gets you $15,000 of Opus 5.5 in a month, but only around $3,000 of Fable 5.5. Even ignoring that Fable is restricted to 50% of your weekly limit, it burns faster per $ than Opus does. More info below

Game devs, what's your current tool stack? 🎮 Here's mine! A mix of traditional engines, AI-assisted development, and custom tools. Always curious to see how others build their games. Drop your stack below and let's connect! 🤝 #GameDev #IndieDev #AIGameDev

The beauty of open weights and fine-tunes is that you're free to use them however you want. Nobody is forcing anyone to use Arete. The blog post, methodology, and dataset are all public. Judging by some of these reactions, I have to wonder how many people actually read them.
Introducing Arete-27B: Qwen3.8-27B, post-trained to reinforce Western values. Chinese open models are currently the strongest available, but they ship with state-aligned behavior in the weights. We built an 803-prompt eval across seven value categories, including freedom of expression, democracy, and privacy, and measured how often a model adopts China’s party line. After fine-tuning on roughly 53 million tokens, Arete-27B's propaganda rate fell from 22% to 1%, in line with the Western models we tested. Its Hermes Bench score shows no significant performance tradeoffs. The values in an open model are one fine-tune away. Our eval, weights, and training data are available now along with the full blog post: nousresearch.com/arete

After spending so much time working in Unreal, I wanted to see what AI could make with Three.js. 4 prompts and about 4 hours later, I ended up with a game where construction trades beat the shit out of each other on a jobsite. 😂 No grand plans, I just thought the idea was funny. Built with Astra. Trailer made with Codex. #ThreeJS #GameDev #OSHAApproved #connect

Really appreciate everyone sharing their games! 🙏 It might take me a little while, but I plan on checking out every one of them. I'll be coming back to share my experiences and thoughts as I play through them. Thanks for sharing your projects! 🫡

Replying to @chasmmmmmmmmmmm
We added two sentences to Claude Code's prompt on Opus 5.5 to steer it away from recreating someone else's specific game because using Claude to infringe IP is against our usage policy. Original games, genre games, and games built from your own designs and assets are meant to keep working. We'll continue to iterate to ensure we're striking the right balance. In the meantime, if Claude turns down something that's yours, send it my way.

I paid for all 64GB, and by God, I'm going to use all 64GB. Come and take my DIMMs, Sam. 🇺🇸😂 #LocalAI #PCMasterRace
OpenAI CEO Sam Altman believes people owning RAM is wasteful, and that it belongs in data centers instead. "From a global allocation perspective, actually, it’s quite terrible to have everyone have a bunch of the world’s limited supply of DRAM sitting in their own computer."
