Before heading on vacation, I built an unofficial @Java SDK for #Google @antigravity 🚀
If you want to embed AI agents directly into enterprise Java applications, #GitHub Actions, or custom #CLI tools, here is how it works and what you can do with it 🧵 👇

Just wait until we get rid of the GIL
I believe Pyronaut can get close to matching Java speeds 🔥🔥
Also have I told you about statically compiled Python yet? 😉 github.com/micronaut-project…

We at least want to compete! Here is the @FastAPI full stack templated ported to @Pyronautfw github.com/micronaut-project…
up to 6x times the throughput in terms of performance and all running in a single VM (Java, GraalPy and GraalJS) 🔥🔥

#LangChain4j 1.21.0 is out! 🚀
Meet Decision Models: instant yes/no, choice and scale answers with probabilities.
Decision Services turn any Java interface into a classifier.
Plus model routing, re-ranking, tool selection, guardrails and agentic routing!

Updated @antigravity in my personal Google AI Pro subscription.
Well hello Claude Opus 5.5 and Sonnet 5.5. Pretty good value for the money here!

I'm impatient to see #Gemini 4 Argon in all developers' hands!!!
Introducing Gemini 4 Argon, our new frontier model, rolling out to cyber defenders starting today, and more widely as soon as possible. I am really excited by the progress we have made here. Argon is priced at $2 in and $10 out during introductory pricing!

The stealth company I co-founded has a name: Hadronic. Java has a strong future, AI and agents are here to stay, and the best way to predict this future is to invent it. Why, and who we are hiring: emmanuelbernard.com/blog/202…

That's what I used for my @Devoxx AI schedule builder, to have a neat devoxx-ai-schedule.cloud.run URL!
Set your own custom URL for @googlecloud Run apps.
Yes, you might want a whole domain (example.com) for your app, but you also may just want an easy-to-remember URL without a bunch of identifiers.
I tried it. So easy!

AI in Java... quixotic, until now!
End-to-end AI stack for the JVM, built from first principles: Tokenizers, quantized matrix multiplication, model format readers, inference engine, vision, speech: all in Java. No external services, no wrappers, no Python, no ONNX.
Will be presented at Devoxx Belgium, next week: "Quixotic: Pure Java Inference at Native Speed"

Planning your @Devoxx Belgium schedule? With 200+ talks across 8 parallel tracks, picking sessions takes time.
I built a personalized agenda generator using @Micronautfw, @LangChain4j, and #Gemini 3.5 Flash-Lite on #Java 25 virtual threads!
Here is how it works 🧵👇

Instead of one monolithic prompt (30-40s), LangChain4j runs 5 parallel day agents on Java 25 virtual threads via `ParallelMapperAgent`.
Run time dropped to ~5s, costing ~1¢. A guardrail agent catches injections early, and deterministic Java code eliminates room collisions.

Not only can you edit Markdown in Drive, but you can also import the file to Gemini Notebook where it’ll refresh each time you open the Notebook. Lots you can do with that!
Looks like you can now view and edit markdown files in Google Drive on the web.
It opens the Google Docs editor, limited to markdown features. Saving the file does not convert it to Docs, it just saves the .md file.

Last weekend to work on your #Devoxx Robots game!
Still polishing levels, squashing bugs, or adding that one last crazy feature? Now’s the time 😅
👉 game.devoxx.be
I’ll also share a short demo of my own game, just as a bit of inspiration/reference 🎮👀
