Ahh, thanks I'll remedy that now, wasn't intentional I'll blame Claude.

It's super hard to tell what's actually happening. Because I've seen other reports that Iran state media halted traffic earlier today, as reported by Washington Post[1]:

> With Trump and Iran each claiming victory, but still far apart on key issues, traffic in the Strait of Hormuz remained at a standstill Wednesday.

Wow thanks, there's not really any dm functionality on hn and I didn't see a clear social handle in your profile. https://github.com/montanaflynn/ has my email.

What do you think of adding prediction market data to the indication? So basically there's this:

https://polymarket.com/event/strait-of-hormuz-traffic-return...

My approach would be if that jumps up to 75%+ it would change to YES. And if we get into May they have one for then too:

https://polymarket.com/event/strait-of-hormuz-traffic-return...

You can actually see in the last 24 hours it jumped up with the ceasefire and Iran saying they would open it and fell back with reports it's been shut down again easlier today.

Edit: I added this, I can see a few downvotes, happy to discuss here or in the github repo if anyone has strong feelings on it!

Funnily enough, I did find a few satellite sources at the beginning for the map background and noticed that all the ships seemed to be scrubbed from the image. It's an interesting idea, thanks for the comment!

The sources I used were:

- ESRI World Imagery[1] — free satellite tiles, high-res, but ships are stripped out from the imagery

- NASA GIBS - VIIRS[2] — near real-time daily satellite imagery from NASA, but resolution is ~375m so ships aren't visible anyway

- Mapbox Satellite[3] — high-res and looks great, but same deal — ships are scrubbed from the composited imagery

Totally agree, I put some text and tried to make it clear. My first intention was to find some live ship tracking API and see how many ships cross the strait, but they were all hundreds of dollars a month, and behind enterprise contact forms.

Totally, and I've heard a lot of it comes down to insurance!

I think I was just spit-balling what would be possible, rather than what I intend to do. As mentioned elsewhere I'm hoping to get an API key from one the data providers, I even reached out to the api behind marinetraffic.com, https://www.kpler.com/product/maritime/data-services to see if they would sponsor the project.

This was just something I built on a whim, but I appreciate your comment and took it to heart!

Yeah! The AIS terrain data is expensive, but the good stuff is from satellite tracking and out of my budget for silly site I built on a whim.

Another funny thing about this was this morning I checked if the domain isthestraitofhormuzopenyet.com was available and it was, and by the time I made the site locally, put it on vercel I went to buy the domain to point DNS to it someone had bought it! I renamed it to the current site url / repo which i think might be a little nicer to type, but crazy that we had same idea on apparently the same day. I was also just telling a friend about simultaneous invention aka multiple discover[1] a few days ago, so another case of the Baader-Meinhof phenomenon[2]!

Great point and something I didn't consider, I should make a big disclaimer it's not meant to be fully accurate or live data. Thanks for the comment!

Fair enough, I'm actually not scraping it on any automated cycle currently, I just manually copied the JSON from their site to get some ships on the map.

There's a few live ship tracking APIs I considered but they are expensive or their free offering just straight up didn't work. I sent a few an email if they would consider sponsoring the project, no replies yet.

    - AISStream.io — https://aisstream.io — Down/not working
    - DataDocked — https://datadocked.com — Ran out of credits on a single failed request
    - VesselFinder — https://www.vesselfinder.com/realtime-ais-data — Enterprise contact form, asked if they wanted to sponsor in exchange for a link
    - MarineTraffic — https://www.marinetraffic.com, their API is like an enterprise contact form, same as above, waiting for response.

Their APIs are protected by cloudflare, I didn't want to circumvent that. Also I dont really want to make a chrome extension or have a browster tab open, if that's what you meant? I've already made a cron style agent framework[1] so that's what I'd probably reach for since they can actually open the browser and inspect the network traffic to grab the json.

So if it's under 25% of the prior year's crossing it goes to NO, otherwise it's counted as open.

The update cadence kinda sucks because I didn't spring for the $200 a month live ship tracking data, so I'm using https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a... which lags by 4 days which isn't great for a site like this, but was fine for me on a little side project. Open to other data sources or ideas, of if anyone wants to sponsor an API key (I did reach out to a few vendors already if they would give the project api key in exchange for a link to their site).

The original idea was to track ships and see how many crossed the strait but as mentioned above I didn't find any free sources so I went with what I did.

The console / login pages are showing an error still.

Seems like you're experiencing the hacker news hug of death.

So the announcement said the API works with the new model, so I updated my Golang SDK grail (https://github.com/montanaflynn/grail) to use but it returns a 500 server error when you try to use it, and if you change to a completely unknown model it's not listed in the available models:

  POST "https://api.openai.com/v1/responses": 500 Internal Server Error {
    "message": "An error occurred while processing your request. You can retry your request, or contact us through our help center at help.openai.com if the error persists. Please include the request ID req_******************* in your message.",
    "type": "server_error",
    "param": null,
    "code": "server_error"
  }

  POST "https://api.openai.com/v1/responses": 400 Bad Request {
    "message": "Invalid value: 'blah'. Supported values are: 'gpt-image-1' and 'gpt-image-1-mini'.",
    "type": "invalid_request_error",
    "param": "tools[0].model",
    "code": "invalid_value"
  }

Yeah I just tried it and got a 500 server error with no details as to why:

  POST "https://api.openai.com/v1/responses": 500 Internal Server Error {
    "message": "An error occurred while processing your request. You can retry your request, or contact us through our help center at help.openai.com if the error persists. Please include the request ID req_******************* in your message.",
    "type": "server_error",
    "param": null,
    "code": "server_error"
  }

Interestingly if you change to request the model foobar you get an error showing this:

  POST "https://api.openai.com/v1/responses": 400 Bad Request {
    "message": "Invalid value: 'blah'. Supported values are: 'gpt-image-1' and 'gpt-image-1-mini'.",
    "type": "invalid_request_error",
    "param": "tools[0].model",
    "code": "invalid_value"
  }

I made this app to scratch an itch of mine caused by flakey ethernet connection through my dock. Fairly often my internet connection falls back to wifi instead of ethernet though my dock. There's no built-in menu bar icon I could find to show ethernet connection status and opening the network pane in system settings was tiresome. So I decided to make my first mac app!

Claude code wrote all the code, openai generated the app icon. I wrote a small golang program to take the 1024x1024 png from openai and resize/rename it to the expected iconset format and json file.

This was a fun experiment, I don't think there's ever been a time where people could so easily create native applications!

Thank you, this has been fixed!

Wow I had not known of that! This is mostly just a quick tool I wanted but something to think about if anything further were to come from it.

There is an example linked to on the homepage of this submission but here it is:

https://asxiv.org/pdf/1706.03762

Possibly. I had to kind of be very specific to get the model to link to the pages in a specific format my frontend can parse and then interact with the pdf viewer[1]. It seems very full featured so it may have a way to highlight portions of the page, but my experience with PDFs leads me to believe it would be tricky.

1. https://mozilla.github.io/pdf.js/

That seems like a social network? This is just a tool to have an AI model answer questions without needing to do anything other than replace the domain.

I've had better results running it with the Gemini 2.5 Pro model but it's much more expensive. The website is using the very cheap 2.5 flash lite model.

You can run it yourself using the better model to see if you get better results as well:

https://github.com/montanaflynn/asxiv

Very cool! I chose gemini for two reasons; the first being it supported pdf input and the second the flash lite model being very cheap so I could comfortably make it public and free.

Thank you, that's probably correct. I think the gemini api might turn the pages into images and use those. Sending the original tex source was something I thought of but not all papers have those submitted.

As for markdown / latex output that could be done, especially for equations! I'll have to look into the best way to render that.

I hadn't, but at a glance it seems more of a community that an AI tool?
