You may learn something from my experience building the same thing: https://www.joshbeckman.org/narro/

Thanks, this is very valuable. I sent an email.

This is very cool, for sure. But what I'm looking for is something that is super optimized for threaded conversations, like this site. Imagine if each poster were a unique voice, and the format was basically listening to all of the top conversations for a given post, in a way that makes it easy to follow the conversation and back-and-forth from the threads. There would clearly need to be a little bit of design applied and some simplification, but I think that's where some GPT element could come into create a simplified conversation with a condensed amount of speakers.

Interesting, I think the point about processing with GPT is important. Our thing started as naive narration but many articles are hard to follow when simply narrated.

What I've been dreaming of is a "podcast" generated for a day of HN, but focusing on the comments and conversations.

I come here for the convos. But I also commute in a car, and I exercise with headphones.

I want like a radio show made of segments. Each segment is a post with the best conversations between users. Use a generative Ai voice service (like Coqui), and have it speak the comments aloud.

Then I can listen to interesting chatter through my headphones.

Hey, we're working on this!

You have to add articles yourself and it does not have any special logic for HN threads yet.

Turn a YouTube channel into a personal podcast feed. https://gist.github.com/thebenlamm/9d862a3e6c9f481ab9d8a8afe...

More detailed instructions in the script but the general idea is: 1. When a channel publishes a new video IFTT puts a text file with youtube link in Dropbox 2. Script downloads audio from youtube 3. Justcast.com free tier to turn a Dropbox folder into a podcast feed

Hey, I'm building something related and would love to get your feedback on it. I can reply with my contact details if you're interested.

What is the developer experience of using OpenAI's Server-Sent Events endpoint from something else than their Python and Node.js libraries?

The SSE endpoint is required for use cases like chat so the end user doesn't have to wait until the whole reply has been generated.

I started implementing a simple SSE client on top of C#/.Net's HttpClient but it's harder than I first assumed.

We had to restream server events from openai -> our backend -> client. It was pretty simple.

We are working on an AI product in a highly regulated industry (Investing). Recently we have been experimenting using the GPT3 API as a Junior Equity Analyst. On an eyeball check the results of the technology are impressive.

The problem is that there is no way to validate the feedback on scale. I.e., we can't receive statistics about the feedback from the API.

In contrast, for our own Entity Recognition models we can (and do) calculate probabilities that explain why a certain entity is shown.

Hence, I think for API users of GPT3, OpenAI should return additional statistics why a certain result is returned the way it is to make it really useful and more importantly compliant.

You can return log probs per token generated. This can be used to asses the confidence the model has in handling tasks which involve nominal data.

If that’s not helpful, were you getting at having the model return some rich data about the attention weights that went into generating some token?

They seem to achieve the 'multimaterial' label by soaking different parts of the polymer in exclusive precursors. If you want to create advanced microelectronics using this method, you would probably want to be able to control gel-differentiation process as part of polymerization.

"Is now open source!" is the new hot way to say "We quit." Open sourcing software you decided not to bother maintaining anymore is better than nothing, yes, but without a community devoted enough to it to keep it up to date, it's not much better than dead and gone.

Whenever I start a project I usually look for some open source equivalent for inspiration even if it's not maintained. We opened up bonsai in case someone else comes along and wants to understand how we did a few things. There are some fun hacks we had to do to make certain things work around overlaying the main window on macOS that might be helpful for other electron apps.
