An AI agent wrote a Premiere Pro clone

FilmCraft is a free, open-source video editor. Its Rust codebase was written almost entirely by Claude coding agents, not a human engineering team.

Agent-built, not hand-coded — a Rust Premiere clone written almost entirely by Claude agents

Six agents, six hours — roadmap parity jumped 62% to 72% running six agents in parallel

Premiere's own layout — menus, panels and shortcuts copied so Premiere editors feel at home

650 commands for AI — a JSON/MCP control channel lets agents edit, grade and export directly

87% on paper, 50-60% real — the feature checklist looks done, production work isn't yet

What's actually inside

FilmCraft is a clean-room, Adobe-code-free reimplementation of Premiere Pro, written in Rust by Brandon Thomas's team (ex-Square, ex-Storyteller.ai) with Claude acting as the coding agent. It's one of seven ArtCraft apps cloning the rest of Creative Cloud, alongside PhotoCraft, LightCraft and others.

It implements its own H.264, HEVC, ProRes, AAC, VP9 and AV1 codecs from public specs, runs natively on macOS, Windows and Linux, and compiles to WebAssembly for the browser. Dual-licensed MIT/Apache-2.0.

The 62% to 72% jump and the 87% / 50-60% split both come from the project's own dated roadmap, not an outside benchmark — gaps include GPU acceleration and VST3/AU/OpenFX plugin hosting, and the Windows/Linux builds are less tested than macOS.

Requires: a Rust toolchain to build; no GPU acceleration yet; and, for the AI-driving side, either a local model or a paid Anthropic API key — FilmCraft itself is free, but the agent work that wrote it and the one that can drive it run on Claude usage someone pays for.

Try it: git clone https://github.com/storytold/filmcraft and build with Cargo, or connect to its MCP server and drive the 650+ engine commands from an agent.

Use it instead of Premiere when you want an AI agent to script the edit; don't reach for it yet on a paid production job — on the project's own numbers it's only 50-60% ready for real work.

Your agent didn't crash — it did the math

AWS's Well-Architected Generative AI Lens says your stalled agent isn't broken — it's math.
Four pieces of job-queue plumbing bring it back in production.

▶️ Watch the video on YouTube

The math, not a bug — at 95% reliability per step, a 20-step agent plan fails about 40% of the time

Hard deadlines — timeouts set at both the function and the workflow level

Stuck-process cleanup — dead-letter queues and automated cleanup catch what times out

Idempotent retries — a retry without a key can't tell "it worked" from "no answer yet"

Isolated queues — one runaway agent capped so it can't starve or block the others

GENREL03-BP02: timeout mechanisms on agentic workflows

AWS's Well-Architected Generative AI Lens gives this its own best practice, rated High risk if not established. It calls for timeout controls at both the function and workflow level, dead-letter queues for timed-out processes, and automated cleanup and retry procedures.

The numbers come from an independent analysis (tianpan.co, "Why Long-Running AI Agents Break in Production"): even at 99% success per step, a 60-minute job only has about a 55% chance of finishing without an interruption; at 95% per-step reliability, a 20-step plan fails roughly 40% of the time, and agents' own reliability drops noticeably after about 35 minutes of continuous running — hence splitting long tasks into bounded sessions with explicit handoff points, like a git commit.

The second trap, per a HackerNoon piece on the same problem: agents read a timeout as "retry" and a refusal as "stop" — so retrying a call that actually succeeded doubles it, a double charge or a duplicate email sent twice. The fix is an idempotency key attached to every external write, tied to the task's ID, so a retry can tell "already done" from "never happened." Temporal, a durable-execution engine some teams use to run these loops, defaults a model-call activity to a 60-second close timeout with a 30-second heartbeat, and explicitly tells you to turn off the SDK's own retry logic so retries don't get applied twice.

This is a best practice, not a library: it costs nothing to read, and no model is bundled in. Requires: an agent loop already running as a background job, and a queue or durable-execution engine to hang timeouts and retries on — none of this changes the bill for whatever LLM API you already call.

The catch: all four pieces — deadlines, cleanup, retries, isolation — have to work together; skip one and the gap just moves elsewhere.

To try the pattern instead of just reading about it, spin up Temporal's local dev server (the engine the README points to) and watch its default activity timeouts and retries in the Web UI:

temporal server start-dev

Use it instead of guessing at your own retry logic once agents run long enough to need checkpoints. Don't expect code to copy-paste — read the practice, then its sources, and build the plumbing yourself.

Lightroom, rebuilt from scratch in pure Rust

Adobe Lightroom's whole edit engine, clean-room rebuilt as LightCraft — open source, and it already edits raw photos with full color grading and curves.

▶️ Watch the video on YouTube

Runs anywhere — native on macOS, Windows, Linux, or straight in the browser

32-bit float pipeline — every edit is non-destructive, originals stay untouched

Precise masking — select the sky, the subject, or the background

Agent-drivable — AI agents can run the whole app end to end over MCP

One catch — AI subject/sky masking needs a separate SAM 3 model download

What's actually inside

LightCraft is a from-scratch, clean-room reimplementation of Adobe Lightroom's darkroom: exposure, contrast, highlights/shadows, an 8-band color mixer, 3-way color grading wheels, parametric and point tone curves, texture, clarity, dehaze, vignette and film grain — all computed in a scene-referred, wide-gamut, 32-bit float pipeline in the OkLCh color space.

Masking covers a brush, linear and radial gradients, luminance and color range, plus AI-driven sky, subject and background selection, with up to 15 local adjustments per mask. The AI masking modes need a separate SAM 3 model downloaded on top of the app itself — that's the one extra step past installing LightCraft, and the README's own stated catch.

An MCP server ships with the app, so AI agents can open, edit and export photos end to end without a human touching the UI — the README's own before/after screenshots were captured this way, by an agent.

Requires: macOS, Windows or Linux, or a browser via WebAssembly; a separate SAM 3 model download for AI subject, sky and background masking. The README names no specific GPU or memory requirement.

LightCraft itself is free and open source, under MIT OR Apache-2.0. The README publishes no performance benchmarks or speed numbers of its own — only the feature list above. The project is tagged "young and moving fast," so expect missing pieces and fast-moving changes.

Use it instead of Lightroom when you want your pixels staying on your own machine with no subscription attached. Skip it if you need every Lightroom feature today, or deep Adobe ecosystem integration.

To try it, clone the repo and follow the README's Quick start section for the exact build:

This AI drafts your argument, then builds the actual PowerPoint

A short demo turns a research paper into slides: the AI reasons out the structure first, then builds a native PowerPoint file, not a text dump.

▶️ Watch the video on YouTube

Reasons before designing: structures your whole argument before touching a single slide

Real PowerPoint, not text boxes: slide masters, native shapes, transitions and animations

Charts and tables on demand: data-backed visuals built from your content, not pasted images

Any input, local output: feed it a PDF, a doc or just a topic, and it generates the file on your machine

Bring your own brain: it's free and open source, the AI model behind it is on you

How PPT Master builds a deck

It runs as a workflow inside an agent-capable AI tool (for example Claude Code or a similar coding agent), not as a standalone app. You hand it a PDF, a DOCX, a topic, or your own .pptx template, and it reasons out the structure, then writes a native PowerPoint file on your own machine: slide masters, real shapes, data-backed charts and tables, transitions and animations, plus audio narration generated from the speaker notes.

The project doesn't publish any benchmark numbers or timing figures. What you see on its site are the authors' own examples, a research paper rendered as diagrams and native formulas, a brand deck, a pixel-art atlas, not an independent measurement.

Requires: Python, an agent-capable AI tool to host the workflow (Claude Code or similar), and an AI model to do the reasoning, either a local model you run yourself or a paid API key from a cloud provider.

The catch: the tool itself is free and open source under MIT, but it brings no model of its own. The intelligence, and the bill if you use a cloud one, is entirely on you.

Use it instead of hand-building slides in PowerPoint or Keynote when you already have the source document and just want a first full draft. Don't use it if you need a no-setup, click-and-done SaaS deck generator.

To try it:

git clone https://github.com/hugohe3/ppt-master.git

then open the repo's Quick Start and point it at a document or a topic.

Claude just picked up the Pen tool

VectorCraft is a clean-room, open-source rebuild of Illustrator in pure Rust.
It also lets an agent click through the real UI: Pen, Pathfinder and all.

▶️ Watch the video on YouTube

Agents can draw too: an MCP server exposes every tool gesture as a command

Illustrator muscle memory: same Pen, Pathfinder and Layers panels you know

Runs everywhere: macOS, Windows, Linux, FreeBSD, and the browser

Built for speed: 20,000 shapes render in about 27ms, UI holds 120fps

Still rough: tagged "in active development", expect missing pieces

How the agent actually draws

VectorCraft mirrors Illustrator's workflow (Pen, Direct Selection, Pathfinder, Smart Guides, Appearance, Swatches, Layers) in pure Rust, with multithreaded SIMD rendering kept off the UI thread. Every tool gesture is also a command on a JSON control channel, and an MCP server exposes that same channel, so Claude or another agent can draw, edit and export the way a person would, instead of just generating static SVG.

The project's own benchmark: 20,000 shapes render in about 27ms at full retina resolution, with the interface holding 120fps.

Requires: a Rust toolchain to build and run it (cargo run --release -p vectorcraft), or the WebAssembly build for the browser version. Letting an agent draw additionally needs a Claude (or other model) account; VectorCraft doesn't ship a model of its own.

The catch: it's labelled "in active development", so expect rough edges and missing pieces before it matches Illustrator feature for feature.

The editor itself is free and open source (MIT OR Apache-2.0). Running it standalone costs nothing; wiring an agent to it costs whatever that agent's API or subscription already costs you.

Use it instead of Illustrator when you want an open, scriptable editor an agent can drive directly. Don't use it if you need Adobe's plugin ecosystem or a finished, polished app today.

Open source shader components, but the good presets cost $199/year

The video showed hand-coding a WebGPU shader for a glowing effect, then dropping in a ready-made component instead.
No GLSL, no WGSL, just an import.

▶️ Watch the video on YouTube

No shader code: drop-in components replace hand-written WebGPU/WGSL

Any framework: React, Vue, Svelte, Solid, or plain JavaScript

Visual editor: drag and drop, exports working component code

AI agents welcome: a Pro-only MCP server lets coding agents pull presets

Free core: 210+ components, MIT licensed, open on GitHub

Shaders: free core, paid presets

Shaders is a component library for GPU-accelerated visual effects (gradients, noise, glass, distortion, glow, cursor-reactive backgrounds) built on WebGPU/WGSL. Instead of managing adapters, pipelines and bind groups by hand, you drop a component like <Aurora /> or <Glass /> into React, Vue, Svelte, Solid, vanilla JS, or Framer.

The open-source core ships 210+ free components, MIT licensed, with the CLI and MCP workflows included at no cost: that's the project's own count, stated on its pricing page. The GitHub repo itself shows 4.3k stars and 173 forks, written in TypeScript as a pnpm/Turbo monorepo.

The catch: Pro costs $199/year (or a one-time lifetime payment) for 750+ premade presets, 55+ ready sections, watermark-free HD export, a Framer plugin, unlimited version history and priority support. The engine stays free, you'd be paying for design output and drag-and-drop convenience, not for more code. The product is also explicitly in public beta, per an independent review on the OpenReplay blog.

Requires: a WebGPU-capable browser to render the effects, and Node.js with pnpm if you're building from the monorepo source yourself.

Use it instead of hand-rolled WebGPU/WGSL or plain CSS gradients when you want a drop-in glow or distortion effect fast. Don't reach for it if you need full 3D scene control like Three.js, or want the presets and HD export without paying.

To try the free core, clone the repo and build the monorepo:

git clone https://github.com/shader-effects-inc/shaders.git
cd shaders
pnpm install

Then pick a component for your framework. The Pro tier and its presets live at shaders.com/pricing.

70B on a 4GB GPU, no quantization

AirLLM streams a model's layers off disk one at a time, so a 70B model runs on a card with 4GB of VRAM. The video is the forty-second cut, this is everything behind it.

▶️ Watch the video on YouTube

No shrinking the model: no quantization, no distillation, no pruning, just streamed layers

One line of code: loads Qwen, DeepSeek, Llama, Phi, Gemma and more via AutoModel

Training too: the same streaming trains a 125B model under 6GB of VRAM

DeepSeek V3 at 671B: runs in about 12GB, by the project's own FP8 measurement

Kimi K3 under 4GB: the largest open model yet fits, but needs a special build

How the layer streaming works

AirLLM splits a model into per-layer shards and loads each layer from disk into GPU memory only when it's needed, then frees it before the next one. No quantization, distillation or pruning: same weights, just not all resident at once. One AutoModel.from_pretrained(...) call handles Qwen, Llama, DeepSeek, Phi, Gemma and more.

The project's own measurements: Qwen3.8-27B (dense VL) in 3.33GB on an RTX 3090; Qwen3.8-Flash-Next (125B MoE) in 5.95GB on an RTX 4090; Kimi K3 (2.8T, the largest open model released to date) in 3.72GB on an RTX 6000 Ada; DeepSeek-V3 (671B, FP8) in about 12GB. A newer training mode streams frozen weights the same way: Qwen3.8-Flash-Next trains under 6GB on an RTX 3060 Ti.

The catch: those headline numbers need record-specific builds, not just pip install. Kimi K3 needs compressed-tensors and flash-attn (its model code mandates flash attention) plus a CUDA 12 torch build, and Flash-Next needs transformers built from source (pip install git+https://github.com/huggingface/transformers.git) and about 360GB of checkpoint disk. The README doesn't publish a tokens/sec figure, so expect streaming from disk to cost speed versus a model that fits in VRAM outright.

Requires: an NVIDIA GPU (as little as 4GB VRAM for a 70B model) or MacOS/CPU, enough disk for the split checkpoint, and for the largest models the extra packages named above.

Free to run: AirLLM itself has no fee, but you still need the model weights and a GPU, local or rented, to hold them while they stream.

Use it instead of renting a bigger cloud GPU when you want to try a huge model on hardware you already own. Don't use it if you need fast token throughput.

Try it: pip install airllm, then from airllm import AutoModel and AutoModel.from_pretrained("Qwen/Qwen3-32B").

Decisions, not essays: one forward pass, 33 milliseconds

Laya is a non-autoregressive decision engine: feed it any text and it answers with a typed choice, score or yes/no.
No tokens generated, no essay, just the answer, straight from the forward pass shown in the video.

▶️ Watch the video on YouTube

No token generation: a single forward pass returns a typed choice, score or yes/no

Router per request: auto-picks the right checkpoint across 100+ languages

33 ms per call: one call, one typed answer, no essay

Long documents, too: up to 8,192 tokens, about 1.7 s on a 4,000-token document

Zero-shot vs fine-tuned: 0.362 base accuracy, 0.766 after fine-tuning on their benchmark

How Laya decides in one pass

Laya is non-autoregressive: no tokens are generated. One forward pass returns a typed choice, score or yes/no (called "noul"), trained with reinforcement learning against strictly proper scoring rules (RLCD). A router reads the text, picks the English or multilingual checkpoint, and sends the request there, covering 100+ languages.

The 33 ms figure and the long-document numbers are the project's own measurements. The 1.7 s is for a 4,000-token document on an Apple GPU, measured with the included research/scripts/bench_long_context.py script. The multilingual checkpoint ships with a 1,024-token cutoff by default, so long documents need max_len=8192 passed explicitly, and accuracy past 4,000 tokens gets more variable: the authors report 16 to 18 of 20 requests correct up to about 4,000 tokens, versus 8 to 17 of 20 beyond that.

The accuracy numbers come from the authors' own typed-decisions benchmark of 2,000 decisions across four workflows. The base English checkpoint scores 0.362 zero-shot; their fine-tuned laya-typed-decisions checkpoint scores 0.766. The catch: that jump needs fine-tuning on your own decisions, using the provided Kaggle 2xT4 notebook or an Apple Silicon MPS script, not the stock zero-shot model.

Requires: Python 3.10 or newer, pip or uv. pip install laya downloads a Hugging Face checkpoint on first use and runs locally, no API key needed. Apache 2.0 licensed.

Use it instead of calling an LLM API when you just need routing, triage or a scored answer. Don't use it if you need open-ended text generation rather than a fixed-schema decision.

Try it: pip install laya then laya "My payment failed twice" --preset triage

One menu bar app, every coding agent, any model

The video showed magpie switching Claude Code, Codex and Gemini CLI to different models from one menu bar app, with no config file touched by hand.

▶️ Watch the video on YouTube

Locked no more: each coding agent ships tied to one model provider, magpie breaks that link

One local gateway: a server on your machine speaks every agent's own API and serves them all

Any model, one list: pick a model for any agent, magpie edits the one key in its config

Click, and it switches: Claude Code onto Kimi, Codex onto DeepSeek, Gemini CLI onto GLM

The catch: you still need your own API key or subscription, magpie only routes to it

How magpie actually switches a model

magpie runs a local gateway, by default on 127.0.0.1:3425, that speaks OpenAI Chat, OpenAI Responses, Anthropic Messages and Gemini, translating between them with streaming and tool calls included. Point an agent at it, and the gateway forwards to whichever provider you picked for it.

Picking a model on the Agents page rewrites the one key that matters in that agent's own config file, in its own format, keeping the agent's comments and formatting intact. That is how Claude Code ends up on Kimi, Codex on DeepSeek, or Gemini CLI on GLM, and how OpenCode can run on your ChatGPT plan instead.

Routing groups add fail-over: when one account or model runs out of quota, magpie quietly moves to the next one in the group and the agent never sees the error.

Requires: macOS, Windows or Linux (menu bar app, window, TUI, web UI or CLI), a Docker host, or Termux on Android. You still need your own API key (DeepSeek, Kimi, GLM, OpenRouter...) or a subscription (Claude, ChatGPT, Copilot, Gemini, Grok) an agent is already signed in to; magpie finds those sign-ins by reading local files and the Keychain, and you can switch that off in settings.

The README names no benchmark numbers: this is a routing and config tool, not a speed claim. Model lists and names come straight from each vendor, filled in with reasoning levels from models.dev.

Install with curl -fsSL https://usemagpie.ai/install.sh | sh, with go install github.com/yetone/magpie@latest, or via the Docker image; Mac builds are signed and notarised and self-update. It is free and MIT licensed. Use it instead of hand-editing every agent's config when you run more than one agent, provider or account. Skip it if you run a single agent on its own vendor plan, you don't need it.
