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.

The brand new #DevoxxGenie RAG feature is now available on the @jetbrains.com marketplace v0.4.1. 🚀 /find #Upgrade

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? 🧞‍♂️

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...

Yes the nearest of what you are looking for is what @aurelievache.bsky.social and her community built with developers.events. With @stephanjanssen.be we work a bit on such services but it’s limited to #devoxx / #voxxed ecosystem

Anthropic’s #Claude Sonnet is increasingly overwhelmed with requests. Luckily, #DevoxxGenie gives me the flexibility to work with any LLM provider! #LLM #AAP #Overloaded
