This is an excellent essay by @maevyn.codes about the current state of AI driven software development and its opportunities and limits.

Missed #IntelliJIDEAConf 2026? In “Sandboxing AI Agents With GraalVM” @thomaswue.dev shows how to run AI-generated code in a sandbox with controlled API access. Watch on YouTube: youtu.be/y8HtFI5JNlE

GraalVM sandboxing provides a controlled execution boundary for customer-supplied, dynamically loaded, and AI-generated code. Learn how to restrict host access, enforce resource limits, and contain failures: medium.com/graalvm/sand...

Can you safely give an AI agent the ability to execute code? At IntelliJ IDEA Conf 2026, @thomaswue.dev will show how GraalVM enables sandboxed AI agents with explicit host APIs, isolated execution, and bounded resources. 🗓 September 8–9 👉 Register now: jb.gg/3vwzgv #IntelliJIDEAConf

This @graalvm.org 25.1 release is the first in our series of monthly innovation releases that bring the latest performance improvements to our users for free. If you are using Java 25, definitely try the upgrade!

GraalVM Community Summit is back for its 6th edition! 🚀 Join our team, contributors, and partners in the JVM ecosystem for two days of presentations, working sessions, and collaboration on the future of GraalVM! Learn more and join: graalvm.org/community/su...

Looking very much forward to this talk on 6th of May at @devoxx.uk together with @starbuxman.joshlong.com where we will demonstrate the latest of how @graalvm.org and Spring can work great together!

Cool to read how @springio.net has real-world impact: medium.com/graalvm/insi...

trivago runs a GraphQL gateway handling 9,000+ req/s per subgraph. After migrating to GraalVM Native Image, they: — eliminated warm-up — reduced replicas from 43 to 12 — cut CPU usage Learn more about their migration process and recommendations: medium.com/graalvm/insi...

Excited to have a session together with @starbuxman.joshlong.com at @devoxx.uk on 6th of May! Let's see if Josh can out-code the AI! Also, we will show a novel way to embed AI into the Spring PetClinic application with @graalvm.org. 🤖🏆

Learn how Picnic built a rule engine on GraalVM, where rules are defined in JavaScript or Python and executed by a Java backend, handling 37M evaluations and 2M actions daily 🚀 medium.com/graalvm/java...

Do you actually need JIT, or are you paying for unpredictability? @thomaswue.dev (Founder of GraalVM) explains when JIT makes sense, when it doesn’t, and why predictable performance matters more than peak numbers. 🎥 Watch: youtu.be/naO1Up63I7Q #GraalVM #Java #Performance #Compilers

Mixing JVM and non-JVM languages in one runtime? At IntelliJ IDEA Conf 2026, @thomaswue.dev will show how GraalVM enables true polyglot development. 🗓 March 26–27 👉 Register now: jb.gg/3vwzgv #IntelliJIDEAConf

Had an extensive conversation with Marco at @jetbrains.com about the future of @graalvm.org, the benefits of ahead-of-time compilation, and whether AI is going to take over compiler development 😉.

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec. Join @ssmith.bsky.social and me at @jfokus.se next month to learn more: www.jfokus.se/talks.html?s...

Trying out the upcoming Spring Boot 4 + @graalvm.org 👀 A complete Spring Boot web service: — compiles to native in 33.8s (quick build mode) ⚡️ — starts in 0.034s 🎉 🚀🚀🚀

People that complain GraalVM native builds are slow still live in the stone age 😅 Obviously native builds will remain slower, but the improvements the Graal team made the past years on the compiler (and resource usage!) are seriously impressive 👍

The @kotlinlang.org team at @jetbrains.com is working on a @graalvm.org-compiled kotlinc. Early experiments look very promising: > So far, a native image with PGO offers a properly "warmed-up" kotlinc and with up to 20% more peak throughput. Ticket: youtrack.jetbrains.com/issue/KT-823...

Quarkus continues to focus on native for swift start-up time and low memory footprint. Learn more in By Severin Gehwolf's blog post, "Continued Focus on Native" quarkus.io/blog/continu...

Really great to see plans for adding better integrated support for running @graalvm.org language implementations for JavaScript, Python, and WebAssembly in your Spring applications! github.com/spring-proje...

Very happy to see participants from so many different companies at the @graalvm.org Community Summit 2025!
