Smart Thumbnail AI Agent

Let AI agents choose the perfect thumbnail from your videos!

What it does

A good thumbnail is the biggest reason people click. With Smart Thumbnails, you can ask your AI assistant to get you the best thumbnail from any video that is statistically most likely to drive clicks and engagement. The thumbnail is literally the only part of your video that every potential viewer sees. A blurry, mid-blink, half-dark frame buries great content. That's why we launched Smart Thumbnails to automatically choose the perfect thumbnail from your videos to boost engagement!

Auto-select the best video frame for thumbnails using AI. Increase clicks and engagement with intelligent frame extraction.

Smart Thumbnails use machine learning to analyze your video and automatically select the most engaging frame for preview images. Instead of random frame extraction or manual thumbnail creation, the API identifies faces, compositions, colors, and scenes that maximize click-through rates. For platforms managing thousands or millions of videos, this means better engagement without manual oversight. Send a video file to the /v1/start_encode2 endpoint and add smart_thumbnail as an output format in your job request. The model scans multiple frames across the video duration, evaluating composition, brightness, contrast, and visual hierarchy. The API identifies the frame most likely to drive…from cloud.qencode.com

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

  • Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
