Show HN: SpongeCake – open-source SDK for OpenAI computer use agents https://ift.tt/z8YwCGj

Show HN: SpongeCake – open-source SDK for OpenAI computer use agents Hey HN! Wanted to quickly put this together after seeing OpenAI launched their new computer use agent We were excited to get our hands on it, but quickly realized there was still quite a bit of set-up required to actually spin up a VM and have the model do things. So we wanted to put together an easy way to deploy these OpenAI computer use VMs in an SDK format and open source it Hopefully this tooling is helpful to other folks building AI agents! Here’s a link to the repo ( https://ift.tt/pXdc59F ) - please try it out and give us a star. If you have any feedback, add it as a comment to this post! Or if you simply just love spongecake, show support for the delicious treat https://ift.tt/pXdc59F March 20, 2025 at 10:16PM

Show HN: Codemcp – Claude Code for Claude Pro subscribers – ditch API bills https://ift.tt/ABrR5kh

Show HN: Codemcp – Claude Code for Claude Pro subscribers – ditch API bills Hi all! I normally work on the PyTorch project but I've been on baby leave for the past month, so I've been playing around with AI as a user rather than a framework implementor. I really liked the agent experience with Claude Code, but I couldn't really justify spending so many dollars on API costs for random side projects. I already pay for a Claude Pro subscription though, and it turns out you can simulate many of Claude Code's features with an MCP. If you have a Pro subscription, check this out! I think it really captures the Claude Code experience quite well, without forcing you to pay for API tokens. https://ift.tt/pRfhSMl March 13, 2025 at 11:59PM

Show HN: I built an extension to book Airbnbs directly https://ift.tt/rkvwedz

Show HN: I built an extension to book Airbnbs directly Hi Hackers, My wife and I have been slow traveling around the world for last 3 years, and our top travel hack that has saved us most amount of money is to book directly with Airbnb host. We usually rent for a month so savings in fees are easily ~$300 - $500 on each stay, i.e. about 15-20%. Not every host offers it we respect that, but there are so many hosts out there that would rather have you book directly via their website and we as guests want the same. The problem is these hosts can’t promote or say that on Airbnb. This inspired me to build OpenBnB.org, where I’ve started collecting direct booking websites of hosts. So far, I have around 1,500 hosts representing 150,000 listings – most of them in USA. The idea is to give guests more options to book, and hosts another channel to distribute their listings. The first solution is a browser extension that makes it really easy to find the direct booking website of hosts when you’re browsing Airbnb. It just a one-time easy install with no sign ups. It: 1) highlights all the directly-bookable listings on the search page, 2) lets you search listings only from hosts with direct booking option and then of course 3) gives you the direct booking link on the listing page. What I like about this solution is it doesn’t require guests to go to a different website; they can just browse Airbnb (largest inventory of short-term rentals) as usual and get more options to book when available. Other than savings, I think there is something about the direct relationship with hosts and guests, without any intermediaries. The cool think is I estimate about 20-33% of Airbnbs can be booked directly! That means I’ve only collected around 6 to 9% of all directly-bookable listings around the world. I’ve seen some other chrome extensions do something similar, but none of them highlight these listings nor let you search listings only with hosts that offer direct booking. What do you think? Try it out and let me know if this is useful. I’m also planning to spin up a website that only has listings from these hosts, kind of like a meta-search engine for vacation rental websites. https://ift.tt/rGqe0PO March 20, 2025 at 01:37AM

Show HN: We built an agentic image editor that preserves the original structure https://ift.tt/oPR4ESC

Show HN: We built an agentic image editor that preserves the original structure Hi everyone, I’ve been experimenting with app where you can edit images in your camera roll simply by tweaking your photo’s metadata (changing location/time) and our agent will contextually regenerate the photo in that place & time in one shot. There's no prompting involved. One of the hardest problems we’ve seen with these ai image editing/creation tools is that they struggle with preserving the subjects of the original image (faces, genders, number of people, bodies, animals, etc), and I think we’ve gotten a step closer to making it feel more realistic. The gallery has some examples that people have been regenerating. https://ift.tt/7AdIWBh Here’s a demo: https://ift.tt/tgaewYk Feel free to dm me on Twitter: https://twitter.com/sakofchit if you’d like to try out the TestFlight in the meantime Would love to know what y'all think! https://ift.tt/7AdIWBh March 19, 2025 at 11:14PM
