@0xwhrrari Same pattern works inside an editor, on real footage.

In @getopenscreen, Opus 5.5 writes the effect as a GPU shader, it lands on the timeline with its own sliders, and it checks its own frames before stopping. Same pixels in preview and export.

@_yukungao Thanks!

OpenScreen 2.1 is out, and it's a big one.

Two things change what you can ship:

→ demos made by your agent, attached to your PRs
→ virtually unlimited visual effects: if the menu lacks one, your agent writes it

Free, open source. Windows, macOS, Linux.

@OpenAIDevs Setup for ChatGPT, Codex and Claude Code: https://t.co/zcI9D5gANK

[Lescot Etienne @LescotEtienne]

OpenScreen now works as a plugin in the ChatGPT desktop app.

Add the marketplace getopenscreen/openscreen, install the plugin, then ask it for a demo video in one sentence. It plans a timed storyboard first, then records, edits and exports the MP4.

@malmgrenkevin @alexandr_wang Built one: MuDesktop. Projects, a review panel, terminal and browser, worktrees, MCP, opt-in computer use. Free, open source, in the Microsoft Store and notarized on macOS.

[Lescot Etienne @LescotEtienne]

@mjdouglas MuDesktop runs whatever Muse Code you have installed, so 1.4.8 works in it as is. A desktop app for Muse Code: projects, review panel, worktrees, MCP, opt-in computer use. Now in the Microsoft Store and notarized on macOS. Free and open source.

I built MuDesktop, the desktop app for Muse Code, Meta's coding agent.

Projects, live tool calls, a review panel, terminal and browser, git worktrees, MCP, and opt-in computer use. Free and open source, on Windows and macOS.

An independent project, not affiliated with Meta.

Trending in 15 s: Diagram Design, an agent skill for editorial diagrams.

One diagram in three styles, then the exploded AI agent stack replays layer by layer. Self-contained HTML + SVG, no Mermaid slop.

Harness², from Google Research: keep the model fixed, improve the harness around it, recursively.

Propose edits, probe them on the same task, compose a better harness, then learn how to improve the next one. On one JobBench task: 43.1 → 77.8.

DeepSeek-V4.1-Flash-1017 in DeepSeek Harness: one request, sped up.

It plans, then turns a bare page into a trail finder: search, difficulty filters, sort by distance, dark mode. Plain HTML, CSS and JS. The status bar reads ~300 tok/s.

Trending in 15 s: Anima, interactive biology figures made by Claude.

Hover a receptor and it explains itself, slide the dopamine level, block D2 and watch the signal flip. Then a firing neuron whose numbers come with their sources.

Trending in 15 s: MonoCode, a GUI for your coding agents.

Its Monos are agents that work across your projects: one request, the Mono starts a session in the project, then reports back with the changes.

Trending in 15 s: llmspeed, feel local LLM speed before you buy.

Same model, same prompt: RTX 4090 1.8s vs MacBook M4 Pro 5.0s. Then a Mac Studio M5 Ultra takes the next race in 1.5s.
