Take Control of Standard 4D Components
As a 4D developer, you often want full control over what gets included in your projects. Starting with 4D 21, you can now decide which components provided by 4D are part of your application.
4D 21 and AI Kit: Redefining how applications Think and Act
With 4D 21, AI takes a giant leap forward. At the heart of this evolution is AI Kit’s tool calling, a massive addition that transforms the way you integrate AI into your applications.
Tool calling allows you to extend the model’s capabilities by registering your own methods or functions, which the AI can call automatically when relevant. This means that instead of manually handling every interaction, the chat helper automatically invokes your handlers, giving you both flexibility and control.
4D 21 Beta Starts Today
Beta testing for 4D 21 starts today—enabling you to run semantic vector queries directly in ORDA, use AI tool calling to expose 4D methods inside AI conversations with structured responses, and maintain 4D Remote sessions uninterrupted across network changes. If you’ve ever needed smarter queries, tighter AI integration, or more resilient client connections—this release delivers.
4D 20 R10 is Here
Introducing 4D 20 R10 – Available Now!
You don’t need more features. You need deeper ones. The kind that add meaning to your data. That catch mistakes before they happen. That react in real time, adapt to structure, and make intelligence feel native—not layered on.
4D 20 R10 does exactly that—richer context, tighter control, smarter defaults. It’s not just powerful. It’s purposeful.
Find the right spot in your 4D Write Pro document with AI
In 4D applications, large documents are commonplace: financial reports, internal guidelines, technical manuals… Searching for an exact keyword often isn’t enough. Scrolling through 30-page reports to find one paragraph is not only time-consuming but also error-prone. This is where AI can help.
The semantic approach based on vectors, introduced in 4D 20 R10, already makes it possible to find a relevant 4D Write Pro document even when different wordings are used (for example, “insert image” vs. “add picture”).
But what happens when a document spans multiple pages and covers various subtopics? Even if the entire text can be converted into a single vector, results are often better when we work at a finer scale. This is the idea behind chunking: splitting a document into coherent segments, each represented by its own vector.
This is precisely what allows us to go further: retrieving not only the right document, but also the exact passage that matches the search.
Search by Meaning, Not Metadata: Semantic Image Filtering with 4D.Vector
Your users don’t think in filenames or folder hierarchies. They think in ideas.
- “A robot painted in watercolor.”
- “A sunny beach filled with color.”
- “Something that feels like Mona Lisa… but from the future.”
It doesn’t matter if that idea comes from an image, a customer order, an email, or a 4D Write Pro document — the challenge is the same: how do you deliver results that match intent, not just keywords?
With 4D.Vector and 4D AI Kit, your application can finally make sense of meaning. In this post, we’ll illustrate it with semantic image similarity search. And here’s the key: we’re not really working with raw images at all — we’re working with their descriptions. The very same approach works for any kind of text data in your application.
Intelligent 4D Write Pro document analysis with AI
In many business applications, users enter or receive unstructured text: customer feedback, internal notes, support tickets, reports, and more. This content represents valuable information, but it’s difficult to leverage without specific processing.
This is where artificial intelligence becomes a powerful tool: by automatically analyzing the written content of a 4D Write Pro document, it can extract useful metadata for understanding, sorting, or prioritizing.
In this demonstration, we’ve implemented a complete scenario of automatic analysis of 4D Write Pro documents using AI. From a simple text, the AI is capable of:
- Generating a concise title reflecting the content
- Identifying the tone (positive, negative, informative, urgent…)
- Suggesting classification tags
- Evaluating the document’s writing quality
The goal is clear: automatically enrich documents with usable metadata, without changing the user experience.
UUID Improvements and Sorting with Version 7
Starting with 4D 20 R10, UUIDs are now generated directly using an internal algorithm instead of relying on system functions—giving you better control over their format and behavior. And with this update, you can now opt for version 7 UUIDs, which support chronological sorting. Let’s explore what this means for your applications.
ORDA – Constructor and touched event – Detailed behaviour through a network
In this previous blog post, you discovered that ORDA entities can now have a constructor, allowing entity instantiation to follow a complete object-oriented approach.
And that’s not all — another blog post introduced the first ORDA data event in a full series: the touched event.
Want to know exactly WHEN and WHERE the constructor and the touched event are triggered while actions move back and forth between a client application and the server? This blogpost is for you.
