GPT‑6 Astra in Roblox Studio.
Ropilot runs OpenAI's newest frontier model inside your actual Roblox project. Describe the feature — Astra reads your game tree, writes the Luau, runs the playtest, and ships the fix. No copy-paste from a browser tab, no manual MCP setup.

What Astra does inside Studio.
The viral demos show what the model can do. Ropilot is how it does it in your real project — with hands, not just answers.
Your whole game
Astra sees your actual place — services, scripts, remotes, and UI — so its Luau references the right instances and fits your architecture.
Luau, in place
It creates and edits Scripts, LocalScripts, and ModuleScripts across files, applied as reviewable changes in the project you ship.
Playtests & fixes
Astra runs the game, clicks through the feature, captures what the player sees, and ships the fix when something breaks.
Start in three steps.
No MCP config, no API keys to wire up. Install once and pick the model.
Install Ropilot Studio
Download the desktop app for Windows, macOS, or Linux. It bundles the Roblox Studio plugin and connects to your open place automatically.
Pick GPT-6 Astra
Open the model selector and choose GPT-6 Astra. Free starter credits from onboarding let you try it with no card.
Describe the feature
"Add a rebirth system with a confirm screen." Astra reads the game, builds it, playtests it, and shows you the result.
Credits or your own plan.

Questions, answered.
Is GPT-6 Astra free?
The model itself isn't free, but you can try it free in Ropilot: new accounts get free starter credits during onboarding, no card required. Astra is a premium model — it uses Ropilot Credits at 2.5x the GPT-5.6 Sol rate. For heavier use, Ropilot Plus is $20/month and credit packs start at $8, or bring a ChatGPT/Codex plan and use Astra at a flat rate.
How do I use GPT-6 Astra with Roblox?
Install Ropilot Studio — a desktop app that bundles a Roblox Studio plugin — open your place, pick GPT-6 Astra in the model selector, and describe the feature you want. Astra reads your game tree, writes the Luau, runs a playtest, and fixes what breaks. No copy-paste and no manual MCP setup. Here's the full step-by-step guide.
Does it work with an existing game?
Yes. Ropilot syncs your real game tree — services, scripts, remotes, UI — so Astra edits the project you already have, references the right instances, and fits your existing structure instead of generating code for a blank baseplate.
Astra vs Sol vs Claude — which should I pick?
Astra is OpenAI's newest frontier model (released September 2026) and Ropilot's premium option — it costs 2.5x the Sol rate in credits. GPT-5.6 Sol is the everyday workhorse, and Claude models like Fable 5.1 and Opus 5 are also in the selector. There's no lock-in: switch per task and spend Astra where the task is hardest.
