Embabel 1.0.0 is GA!!
github.com/embabel/embabel-a…
Thanks in particular to @igordayen and @aheifetz for leading the charge, and to our many community contributors. Open source rocks!
Come see just how nice AI on the JVM can be.

Jev is yet more proof that no organization should outsource its AI strategy to a frontier LLM vendor or company that wants to sell tokens
LLMs are great, BUT
- Open weights models are capable of more & more tasks
- AI > Gen AI. You don't always need an LLM

We live in a time when products can talk to you to help you learn how to use them. The fact that nearly every enterprise AI product is "call sales for a demo" is a massive product red flag, and helps explain why most enterprise AI fails. This is not the 1990s

So not only is Opus 5 a clear regression compared to Opus 4.8, which was itself far more annoying than its predecessors, but in recent days, context compaction has started totally losing the thread.

Anybody else seeing occasional Chinese characters mixed into Claude model output? This was from Fable:

Watching an interview with Anders Hjelsberg. Very impressive. Sharp, clear, pragmatic, to the point. Nothing load bearing; no seams; no performative honesty or unlocks.
A reminder that smart humans can achieve a clarity of communication we're increasingly missing. @ahejlsberg

Your regular reminder that Embabel's structure-aware, agentic RAG goes well beyond naive vector search, and is easily extensible to handle custom sources.
See how easy it is to add quality RAG to your JVM apps!

Nice to see the uptick in star count since Embabel went GA
Remember to star Embabel and the other open source projects you use! One of the easiest of the many ways you can contribute.
Open source community is an amazing thing

Embabel 1.5.0 has just gone GA, supporting Spring Boot 4.x/Spring AI 2.x
Embabel 1.0 supports Boot 3.x
Whatever your Spring version, you can use our sophisticated workflows, agentic RAG and beautiful fluent API!

Vibe coding UIs can be amazing.
Vibe coding infrastructure software is a recipe for unmaintainable, duplicative, buggy disaster. Agents can accelerate enormously, but must be closely managed.
Good software layering is more important than ever.

Strong paper, and good validation of Embabel's core design of dynamically composing atomic actions into a task-specific execution plan, available since May 2025.

ICML researchers just published the agent architecture everyone will copy next year.
One shared graph.
A custom workflow for every task.
Here’s the system:
Step 1 → Break workflows into reusable operations
Step 2 → Store them inside one shared graph
Step 3 → Generate the right workflow at runtime
Step 4 → Reuse state instead of rebuilding context
The result:
Better performance across five benchmarks
Around 4× lower memory usage
Most teams are still hard-coding static agent workflows.
This paper shows what replaces them.
Static workflows are the old architecture.
Runtime graphs are the new one.
Bookmark this before every agent team starts building it.
Then read the full graph engineering playbook below ↓

Opus 5 makes more mistakes than 4.8. Period.
Are we in a period of diminishing returns from the frontier model vendors, despite their greater than ever fanfare?

If there's any superiority of Opus 5 over 4.8 I'm not seeing it. If anything, I've seen more mistakes and poorer instruction following.

Nice to see data-driven flows getting more attention with the graph engineering hype
Embabel has done this since early 2025, with steps linked by data contracts. And its dynamic planning adds another dimension

Ran Opus 5 in a loop overnight with instructions to optimise performance across 50 tests, some very difficult. Also requested regular review by another model to check for overfitting
Woke up to find it had gamed it. Deleted 18 tests on flimsy grounds and stopped running reviews.

A developer vibe-coding a side project a dozen people will ever run, and a team keeping a ten-year-old enterprise system alive for another quarter, share almost no constraints worth naming, and most of the advice in circulation is really one of those two people telling the other how to live.
