24 alternatives to Computer Vision w/o Training Data (Free API)

Starting today, DirectAI’s Zero-Shot Image Classification & Object Detection APIs are public. Define classes and objects exclusively in natural language - no training data required. And if something goes wrong, you can resolve the edge case in natural language too! We’ve been hard at work to bring powerful and controllable computer vision to everybody. To do this, we’re building novel ways of interacting with the knowledge stored in large foundation models. We’re bootstrapping from zero-shot methods to create new approaches that allow for more control over decision boundaries, without…

Build an open-source computer vision model in seconds using text▲64
Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it…

Open-Source Zero-Shot Image Model Server Enabling Model Feedback▲5
Hi everyone! Here is an open source implementation of a decently performant server hosting zero-shot image models (CLIP for image classification, OWL-ViT-ST for object detection), with an extra algorithm to allow users to give the models feedback when they make mistakes! We built a company off this flavor of tech two years ago and have clients who are currently using our commercial API. We are now moving on to other projects but want to make sure our clients still have access to the approaches that they've grown to rely on, so we're open sourcing a simple implementation that they'll be able…

Ideogram 4.0 – open-weight 9.3B text-to-image model▲46
It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch. We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control. It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU. For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/ We will be happy to answer any questions :)
