We've updated our OpenGameEval with Claude Opus 4.7. It's a significant improvement in debugging evals vs. Opus 4.6.
Congrats to @AnthropicAI on the release.

GPT-5.4 with the Roblox MCP server created its own 3D models, animations and GUI.
It's so cool you can make games so easily

Ok I was wrong about MCP servers. They are so fucking fun to use with GPT-5.4 in Codex now

Nice. AI tooling that gets you part of the way there and then gives you precise control to really increase the quality is what I view as the distinction between an accelerant vs a slop generator.

Marvin Te used Rive's AI agent to build a physics system and applied it to his character rig.
He's blending hand-keyframed animation with AI-generated physics. No code background.
Rive's AI isn't replacing artists. It's giving them the power to build their own tools.

We believe AI will support creators in increasing the quality and diversity of their work. We don't see AI replacing creators, and we expect Developer Exchange Fees (DevEx) to continue in their growth.

Enhancements released today to the open source MCP Server for Studio allow for complete agentic loops from any MCP client (e.g. Claude Code) to Studio -- prompt to drive complete edit/run/test/stop loops, converging on outcomes. devforum.roblox.com/t/studioβ¦

I played around with codex app-server and agree it's very cool. Really reduces the friction to embed AI assistantance into an app.

codex app-server is legit af
i was just looking into it for a project and accidentally ended up making an actual native codex iphone app
i can spawn and talk to codexes anywhere on my network
and one of the best parts... I built and linked codex into the actual iphone app and it now runs locally on the actual iphone
gl doing that, cc
