Show HN: A free text-to-image website that supports SDXL Turbo
The homepage of the website allows for free image generation, and in the workflows, there are introductions to nodes related to ComfyUI. In the AI tools section, Pixart-Alpha is currently available for free use. I am still updating this website, and feedback and communication are welcome.

Show HN: Get any piece of Google Earth as a single normalized glTF 3D model
Google released an API in May to get fetch 3D Tiles of anywhere on Earth. Using this in standard 3D engines like Blender is tricky because (1) the tiles are in a geographic coordinate system (2) you get a lot of little tiles at varying quality levels<p>I wanted to simplify this so all you need to do is get an API key, select a map region and a zoom level, and get one combined glTF file that you can throw into any engine. Especially if you're just prototyping and want to see how this data looks in your engine before investing in figuring out all the nuances of the API & coordinate system.<p>(Note that the API prohibits offline use, as in you can't distribute a processed glTF file like this. But you can do this preprocessing in memory whenever you're fetching tiles).

Show HN: Genji – AI browser ninja that can complete any task on Chrome
Hey folks, so I built a chrome extension called Genji, an AI assistant that automatically completes your browser tasks for you. You simply enter your task, and Genji uses GPT-4V to figure out the best browser action to perform next repeatedly until the task is accomplished.<p>The idea is that you can delegate your personal tasks like online shopping or making reservations to Genji. You can also use him professionally to find leads on LinkedIn, send status updates to your boss, or research your competitors and write an analysis document.<p>I’m wondering if you would use Genji as part of your daily routine? Would he be more useful in a personal or professional setting? What concerns do you with using a productivity tool like this?<p>I'm also planning to add voice support and the ability to schedule tasks soon. Do either of these features interest you?<p>If you want to try Genji, download the chrome extension and let me know what you think. It's completely free with no sign up required!
Show HN: DynamiCrafter: Animating open-domain images with video diffusion priors
Hello HN!
I would like to show our recent research project: DynamiCrafter.<p>DynamiCrafter can animate open-domain still images based on text prompt by leveraging the pre-trained video diffusion priors.
It supports:<p>- Image-to-video generation<p>- Storytelling video generation<p>- Looping video generation<p>- Generative frame interpolation<p>We have released source code at <a href="https://github.com/Doubiiu/DynamiCrafter">https://github.com/Doubiiu/DynamiCrafter</a> and deployed a demo at <a href="https://huggingface.co/spaces/Doubiiu/DynamiCrafter" rel="nofollow noreferrer">https://huggingface.co/spaces/Doubiiu/DynamiCrafter</a><p>Please also refer to <a href="https://www.youtube.com/watch?v=PtW7hjCawbo" rel="nofollow noreferrer">https://www.youtube.com/watch?v=PtW7hjCawbo</a> and <a href="https://doubiiu.github.io/projects/DynamiCrafter/" rel="nofollow noreferrer">https://doubiiu.github.io/projects/DynamiCrafter/</a> for more results.
Show HN: I've built a MySQL proxy that supports online DDL
Hi everyone. Over the past year, I've built a MySQL Proxy that supports Online DDL. I'm not sure if there are other proxies out there with this feature, but I found it fascinating and thought it was worth sharing.
Of course, this proxy also supports many other features, such as Read Write Split, Read After Write Consistency, Load Balancing, and Transparent Failover.
I didn't build this database from the bottom up; instead, I forked Vitess and put a lot of effort into overhauling its architecture and SQL Engine Layer.
Moving forward, I hope to introduce more developer-friendly features into this Proxy. The next major feature should be something similar to the Branch functionality of PlanetScale.
