I'm thinking about taking #DevoxxGenie to the next level with Agentic programming. I have a Python POC that meets my needs, but it would be exciting to collaborate with other tech enthusiasts. Maybe we could set up a (virtual) meeting to kick things off. Open to suggestions! youtu.be/kFAgkO6hRDg?...

#DevoxxGenie supports QWen 2.5 Max via the Custom OpenAI REST endpoints 🤩

IDEA and #DevoxxGenie Because it supports all available LLM providers and models and you can switch them during a chat conversation this is hands-down better than CoPilot or AI Assistant. Proof me wrong. github.com/devoxx/Devox...

Just swapped Claude Sonnet 3.5 for Gemini Exp 1206 (2M token context window) using #DevoxxGenie for the past week. The responses? 🤯 Next-level, though they take 1-2 mins to generate. Looks like this is Gemini 2.0 Advanced, and it's still free to use! 🚀

I highly recommend the Valhalla talk by @briangoetz.bsky.social at #Devoxx (www.youtube.com/watch?v=eL1y...). Not only because it gives an excellent view on what is coming in Java, but also because Brian clearly explains why it is important to spend much thinking into crucial language features.

Stephan Janssen@stephanjanssen.be
#DevoxxGenie now supports #RAG based prompt context, powered by #ChromaDB, #Ollama, and #Nomic-Embed all running locally! Plus, try the new '/find' command to trigger semantic search exclusively within your project files 🧠 🧞‍♂️ 🔥 Test it now 🔥 github.com/devoxx/Devox...

Great! It seems @jetbrains.com DiffManagerImpl is annotated with @ApiStatus.Internal, meaning I can't use it for #DevoxxGenie if I want to publish it on the marketplace. Looks like I'll need to develop my own... any suggestions? 🧞‍♂️

Stephan Janssen@stephanjanssen.be
Instead of copying code from the #LLM prompt response, we can now trigger a Git Diff/Merge view in #DevoxxGenie with the suggested code changes. Please give it a try @ github.com/devoxx/Devox...
