1. Is it possible to get it tested on a wide variety of LLM Models? One of the strengths of LangChain is that it allows you to write your tools once, and then use whatever model makes sense for you. (Including with Images/Video/Audio/etc.!). But so far I think really only OpenAI's GPT4o is tested and working with controlflow, and that's not even a good model for most purposes. 2. Can we please fix the ephemeral startup issue 3. Can we please integrate the patch for the LangChain Tools? 4. I'm not sure if throwing EVERYTHING in the system message is really what you want to do! It might make sense to have the context be as a HumanMessage, for example. 5. How active is this project? It seems promising, but a lot of the documentation is out of date/wrong and that's not usually a good sign!

👋 @Dave Aitel! For 1-3, a resounding yess! If it’s submitted as a GitHub issue I can see if it’s a good first issue for the community to contribute or if it’s something we want a core contributor working on. The ephemeral issue is an underlying issue with prefect we’re working on (see below). Yeah this is worthy of experimenting with for sure. IME different models have different sensitivity to instructions passed to the system or first human message, but it’s kind of related to your first point that we’ve bolted on the optimization for a particular model without making it flexible when it doesn’t make sense for others. A lot of the highest leverage stuff for ControlFlow at the moment are improvements made to the underlying orchestration layer in prefect, so that’s where a flurry of work is being committed to ATM. Prefect 3 (which CF is built on) becomes generally available on Sep 3, so that’ll be stable enough to where we can revisit the CF docs to update. But honestly if you see something say something here and on GitHub — if something is out of date with the docs and you want to improve the project then filing a GitHub issue is 🙇 deeply appreciated, and a PR to fix it doubly so. Super grateful for your feedback — have been on vacation while you’ve been posting questions 😅but will be back in on Tuesday and we can 🎸together

Ok, here is the locking traceback btw:
