"If you have zero enterprise apps in Python, that remains the right number." This quote from Rod Johnson (creator of Spring and Embabel) has quickly become one of my favorites. It says that if your enterprise apps are primarily Java, there's no reason to involve Python when adding Generative AI.

Now that Spring AI 1.1.0 is available, I took a pass through the example code for Spring AI in Action and made the necessary changes to build against Spring AI 1.1.0. You can find the changes in the "spring-ai-1.1.0" branch at github.com/habuma/sprin... (see CHANGELOG.txt)

This just arrived! You can get yours at www.manning.com/books/spring... To celebrate, take 50% off any format with the code PBWalls10! (Through 11/27)

Finally received this follow up game to “Compile: Main 1” today. If you like card games and AI, this is a game for you. If you just like AI, then checkout my book: www.manning.com/books/spring...

Woo-hoo! I am delighted to announce that my newest book, Spring AI in Action, is now complete and available at Manning! www.manning.com/books/spring... If you're looking to learn how to apply GenAI in your Java projects, then check out my book.

I’m a huge fan of the Haunted Mansion in Disneyland and Disney World. As such, I decorate my yard with Haunted Mansion stuff at Halloween. Enjoy this brief video of this year’s haunt. I’ve got even bigger ideas for next year.

🚀 Spring AI team is excited to announce Spring AI Agents & Spring AI Bench: - Spring AI Agents: a consistent interface for invoking autonomous CLI-based agents. - Spring AI Bench: open benchmarking suite for Java-centric AI developer agents. spring.io/blog/2025/10...

Wise words from a cookie

FYI: Some of you have heard me mention a card game that my family likes called "Burger Battle". The game is also mentioned in the examples in my book Spring AI in Action. If you are interested in a dice-based Burger Battle, this dropped on Kickstarter yesterday: www.kickstarter.com/projects/bur...

I finally did it. I just ordered a Commodore 64 Ultimate. Such a nostalgic purchase, but it’s gonna be awesome. Want one, too? Here’s a link (admittedly a referral link…I get $10 off of a future purchase if you use this link): www.commodore.net/referral/wrFMflrjC7cF?utm_source=referral_program

Spring AI 1.1.0-M1 is here! Featuring: • Comprehensive MCP integration including the support for Streamable HTTP client & server transports • New MCP annotations framework • Google GenAI SDK integration • Anthropic Claude prompt caching and more spring.io/blog/2025/09...

Got a moment to play Point Galaxy—the newest entry in Flatout Games’ Point games (Point Salad, Point City, and now Point Galaxy)—a couple of nights ago. Quite fun. A bit more complex than Point Salad, but we picked it up fine after a few turns. Can recommend. Cc: @dhinojosa.bsky.social

Who among us had this book, a C64, and would spend days of their youth typing “POKE” followed by some numbers to see what would happen?

Fun thing to try in ChatGPT: "You are a Commodore 64, equipped with Commodore v2 BASIC and the entire memory map of the Commodore 64." Then type: 10 FOR I=1 TO 10 20 PRINT I 30 NEXT You won't have to type RUN...it will run automatically.

Finally went to the mailbox after my trip out of town, so who knows how long this has been there, but… Look what I just pulled from the mailbox! (Now I just need to order that C64 Ultra.)

Ever write some example code that you find yourself actually using over and over? My board game rules chat (github.com/habuma/sprin...), built with Spring AI and HTMX, keeps proving itself useful as I learn new games and need clarification (and don't really want to keep re-reading the rules).

While others around us were blowing up thousands of dollars worth of fireworks, we were playing Tacta.

This is the anthem. Here’s what you came for. This is the moment magic was made for… (Churro shake at Epcot)

Spring AI 1.0 GA is here!!! spring.io/blog/2025/05...

Just learned that my book Spring AI in Action (and other selected titles @ManningBooks) are Deal of the Day today! What timing given the imminent release of Spring AI 1.0.0! Go to mng.bz/WrEx to get 45% off.

Spring AI 1.0.0-RC1 is now available! Looks like I have some updating to do… spring.io/blog/2025/05...

it's go time! Spring AI RC1 is out! spring.io/blog/2025/05...

@dhinojosa.bsky.social and I playing the roles of competing AIs in the game Compile: Main 1

The LAST last milestone (we really mean it this time) for Spring AI dropped yesterday. spring.io/blog/2025/04... There are a few breaking changes, but they’re worth it. Go update those build files now!

I took a moment to experiment with trying to recreate (some of) Google's ADK in Java with Spring AI under the covers. It's rough, has a lot of yet-to-be-done bits, but I think it's a nice start. github.com/habuma/sprin...

Don’t miss this. It’s gonna be amazing.

For fun, I took Google's Agent Development Kit for a spin. I'm still sorting out my thoughts on it. But for now, have a look at what I made: github.com/habuma/misc-...

Observability and monitoring — not security — is the most cited challenge when moving ML models into production, according to a new survey.

I urge you to not take this serious subject lightly. thetalkingapp.medium.com/the-dark-sid...

OMW to @arcofai.bsky.social !!! Looking forward to hearing great talks and presenting a few of my own. See you there.

🚀 The MCP Java SDK core module provides default STDIO & SSE client/server transports - no external web frameworks needed! Build MCP clients/servers in plain Java with both Async (Reactor) & Sync APIs. Spring support is optional. 🔗 Minimal deps: central.sonatype.com/artifact/io....

I realized that a Spring AI+RAG+HTMX app that I created a few weeks ago could be slightly tweaked to become a Spring AI+MCP(client)+HTMX app. And so I thus tweaked it. Check it out at github.com/habuma/sprin....

Whenever I hear phrases like "improve exponentially" or "go up exponentially", I can't help but recall that negative numbers can also be exponents.

For grins, I have been tinkering with creating a few GenAI examples in languages other than Java and libraries other than Spring AI. (Don't worry...I still LOVE Spring AI. Just wanted to see what the others look like.) And now I'm sharing them with you. Enjoy. github.com/habuma/misc-...

Great news! GPT-4.5-preview is available. But... Bad news: Don't get carried away with it. It is priced at $75/million input tokens and $37.50/million output tokens. That's 30 times the price of GPT-4 and 500 times the price of GPT-4o-mini.

AI middleware is the glue that holds your AI-driven apps together, making sure models, data, and existing systems actually talk to each other instead of breaking everything. 👉 blogs.vmware.com/tanzu/what-i...

Following up on yesterday's MCP Server example, here's an MCP Client built with Spring AI 1.0.0-M6. Enjoy! github.com/habuma/sprin...

About a week ago, I started work on this MCP Server. It's the latest incarnation of an MCP Server I've created several times before. This time I started fresh to build it with the new stuff coming in Spring AI 1.0.0-M6. And for grins, I chose to write it in Kotlin. github.com/habuma/tpapi...

It’s a good thing I have a long weekend, because Spring AI 1.0.0-M6 is here! Tool annotations and MCP are the big story, for sure. I’ll be updating all of my Spring AI projects this weekend. spring.io/blog/2025/02...

ICYMI, earlier this week I wrote up some thoughts and shared some experience in how to optimize an API's results in an MCP Server to trim unnecessary token usage. Check it out: thetalkingapp.medium.com/optimizing-a...

I recently spent some time building a Model Context Protocol (MCP) Server around an API and I learned some important lessons. I jotted those lessons in an article at thetalkingapp.medium.com/optimizing-a.... Check it out.

Watching the Nuggets/Hornets game. There should be rules forbidding this color scheme.

Okay, so it's just the 8b model, not the 671b model, so maybe I should gve it a break...but... I was hoping for more.

For those who may not have seen it (or even if you did)… I saw this happen last night watching on TV and was speechless after my initial two word exclamation of “Holy crap!” youtu.be/py2LzH01mpQ

I feel like @spring.io should get a little credit for saving Java from the brink of irrelevance two decades ago b/c as one of my favorite Gartner analysts once said "if you use Java in the enterprise you are using Spring."

I have finally hit 1K followers! Thanks to all of you who helped me arrive at this milestone. Now I suppose I should return the favor by producing some content here worth being followed for. I’ve got some ideas. Stay tuned.
