Building OpenGPTs: A Fully Open-Source GPT Store Alternative

A problem that's impossible to detect is indistinguishable from it working. Hence it works. Hence it's not a problem.

Edit: let me begin with this is fucking brilliant!!

What if the event flow has a time component?

My naive guess is make the time ticker a tool claude can control time.

Which would bifurcate the control surface into two classes: user accessible (keypress) and user inaccessible (fixtures, time).

"tick" would not work for small intervals.

Instead you would need "progress_x_time".

The concept of non-linear problems lingers in my mind.

After the Claude Code source leak, instead of digging through feature flags and anti-distillation defenses, I focused on what I could ship. I focused on reverse-engineering Claude in Chrome from its MCP tool schemas. Clean room, not a fork.

Claude in Chrome blocks 58 domains. Banks, Tinder, Reddit, Robinhood, Bloomberg. Also only works in Chrome and Edge. open-claude-in-chrome has none of that.

Same 18 tools, same performance. Claude doesn't know the difference because it was trained on these exact schemas.

Stuff I found running both extensions side-by-side:

- The official forces deviceScaleFactor: 1 via CDP. Without this, Retina displays make every click miss. Spent an afternoon staring at window.devicePixelRatio to figure that one out.

- It doesn't return screenshots on clicks or typing. Only on screenshot and scroll. I was returning one on every action and burning through the 20MB API limit in 15 calls.

Case study on how I built it: https://www.noemica.io/blog/reverse-engineered-claude-in-chr...

All due respect, no comparison, teddy is a real legend not just cinema. Lets not conflate the two. Much love to chuck though.

Very concerned with this direction of training “counterfactual events such as whether the Waymo Driver could have safely driven more confidently instead of yielding in a particular situation.” Seems dicey. This could lead in the direction to a less safe Waymo. Since the counterfactual will be generated, I suspect that that the generations will be biased towards survivor situations where most video footage in its training data will be from environments where people reacted well not those that ended in tragedy. Emboldening Waymo on generated best case data. THIS IS DANGEROUS!!!

now thx to this post (and the infra provider inclination to appeal to hacker news) we will never know if the model actually discovered the 50 spells or memorized it. Since it will be trained on this. :( But what can you do, this is interesting

I understand this provides a conversation interface for interacting with internet scale data (ChatGPT), but is there any benefit to this over searching in Google then clicking on the top link, (avoiding the ad) clicking accept my cookies, reading the header, scrolling down, Xing out of premium subscription, reading rest of article, repeat for the 4 next links?

Ok bro.

It is designed to be fully modular with the ability to have a human/programmer in the loop at any stage of the process. Enabling you to: - effectively execute hierarchical orchestration :chains: - visualize data in an organized manner - dynamically classify items - etc. (I would love to learn about what you may use it for!)

Excited to share the v0 of OpenGPTs-platform https://github.com/OpenGPTs-platform , an open-source project aimed at replicating and surpassing the "GPT store" with a focus on minimal abstraction, high modularity, and extensibility. Our platform is built to seamlessly integrate a wide array of tools, empowering the community to contribute and expand beyond the existing capabilities of conventional platforms. The initial release features an enhanced "Assistants API" with tools like "retrieval", identical to the one from the GPT store, and a custom "web_retrieval" tool designed for efficient retrieval of information from pre-indexed websites, developed in collaboration with https://huggingface.co/spaces/seansullivan/Better_Langchain_... . Check out our project on GitHub and watch our demo on YouTube https://www.youtube.com/watch?v=yPdIEKb3jWc . Join our Discord community https://discord.gg/23aZEjyjp2 to get involved and help us shape the future of OpenGPTs!
