One of the biggest challenges in scaling AI is that large language models (LLMs) are monolithic. Training them requires vast clusters of GPUs working in lockstep, because the model is a single, dense network where every weight can, in principle, interact with every other. That makes it hard to imagine breaking down training into smaller jobs that could run independently on, say, thousands of consumer-grade GPUs scattered around the world.

But is that strictly necessary? If a model generates Shakespearean sonnets and also writes Python code, do the “Shakespeare neurons” really need to interact with the “Python neurons”? Or could we identify relatively independent regions of the network and train them separately?

Why LLMs Are So Entangled

Modern transformers are designed around dense connectivity. The input embeddings, attention layers, and feedforward blocks are all built so that any token can, at least in theory, influence any other. Add to that the fact that natural language and code often overlap (think “explain this function in English”), and you start to see why training is typically done as a single, inseparable job.

Where Modularity Does Appear

Despite this apparent entanglement, modularity emerges naturally:

Specialized attention heads. Researchers have found heads that reliably focus on tasks like copying, punctuation, or number tracking. Sparse activations. For any given prompt, only a small fraction of neurons fire strongly. A Python snippet activates a different pattern than a sonnet. Mixture of Experts (MoE). Some modern models explicitly enforce modularity: instead of one giant dense block, they maintain a collection of “experts,” and only a handful are activated per token. This allows scaling up the number of parameters without scaling up the compute proportionally.

In other words, while transformers are dense by design, their behavior is often sparse and task-specific.

Could We Train Modules Independently?

Here’s the big idea: if we could reliably identify which parts of a model specialize in poetry versus code versus math, we might be able to train those modules separately and then stitch them together. Some possible approaches:

Activation clustering. Track which neurons/heads fire for certain types of data, and group them into “modules.” Progressive freezing. Train one module on code, freeze it, then train another on poetry. Orthogonal subspaces. Regularize the network so that different domains live in distinct representational spaces.

This would make it feasible to break training into smaller jobs, perhaps even distributed across heterogeneous compute.

The Catch

The problem is that language domains aren’t truly separate. Shakespearean sonnets and Python functions both require reasoning about syntax, analogy, and structure. If we isolate them too aggressively, we risk losing valuable cross-domain synergies. Coordination between modules—deciding which to use at inference time—is also non-trivial. That’s why today’s modular approaches (like MoE or adapters) still rely on a shared backbone and careful routing.

Where Research Is Headed

Instead of trying to cut apart existing dense models, most progress is happening in designing modular architectures from the ground up:

Mixture of Experts for scalable modularity. Adapters and LoRA for lightweight, domain-specific fine-tuning. Compositional networks where different modules explicitly handle different domains and a top-level router decides which to use.

These ideas all echo the same insight: giant monolithic models are powerful but inefficient, and the future likely lies in more modular, sparse, and independently trainable systems.

Closing Thought

The dream of distributing LLM training across a swarm of consumer GPUs hinges on finding the right balance between shared generalization and domain-specific modularity. We’re not quite there yet, but the direction is clear: the next generation of AI systems won’t be monoliths. They’ll be federations of specialized experts, stitched together into something greater than the sum of their parts.

Have you ever needed to let users download a webpage as a PDF without setting up server-side PDF generation? Whether it’s invoices, reports, or certificates, client-side PDF generation can be a game-changer for web applications. In this post, I’ll show you how to implement reliable PDF generation using JavaScript libraries that work entirely in the browser.

Why Client-Side PDF Generation?

Before diving into the technical implementation, let’s consider why you might choose client-side PDF generation:

Advantages:

• No server load – Processing happens on the user’s device
• Instant results – No network round trips for PDF generation
• Privacy – Sensitive data never leaves the user’s browser
• Cost effective – No additional server resources needed
• Works offline – Once the page loads, PDF generation works without internet

Trade-offs:

• Limited to what the browser can render
• File sizes may be larger than server-generated PDFs
• Dependent on the user’s device performance

The Two Main Approaches

Option 1: html2pdf.js (The Simple Approach)

html2pdf.js is a wrapper library that combines html2canvas and jsPDF into an easy-to-use package:// Include the library https://cdnjs.cloudflare.com/ajax/libs/html2pdf.js/0.10.1/html2pdf.bundle.min.js function generatePDF() { const element = document.querySelector('.content-to-convert'); const options = { margin: 1, filename: 'document.pdf', image: { type: 'jpeg', quality: 0.98 }, html2canvas: { scale: 2 }, jsPDF: { unit: 'in', format: 'letter', orientation: 'portrait' } }; html2pdf().set(options).from(element).save(); }

When to use html2pdf.js:

• Quick prototypes
• Simple layouts
• When you need minimal code

Potential issues:

• Can struggle with localhost development
• Less control over the conversion process
• Sometimes has CORS-related problems

Option 2: jsPDF + html2canvas (The Reliable Approach)

For more control and better localhost support, combining jsPDF and html2canvas directly is often more reliable:// Include both libraries https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.5.1/jspdf.umd.min.js function generatePDF() { const element = document.querySelector('.content-to-convert'); // Configure html2canvas const canvasOptions = { scale: 2, useCORS: true, allowTaint: true, backgroundColor: '#ffffff' }; html2canvas(element, canvasOptions).then(canvas => { const { jsPDF } = window.jspdf; const pdf = new jsPDF({ orientation: 'portrait', unit: 'mm', format: 'a4' }); // Calculate dimensions to fit the page const imgData = canvas.toDataURL('image/png'); const pdfWidth = pdf.internal.pageSize.getWidth(); const pdfHeight = pdf.internal.pageSize.getHeight(); const imgWidth = canvas.width; const imgHeight = canvas.height; const ratio = Math.min(pdfWidth / imgWidth, pdfHeight / imgHeight); // Center the image on the page const imgX = (pdfWidth - imgWidth * ratio) / 2; const imgY = 0; pdf.addImage(imgData, 'PNG', imgX, imgY, imgWidth * ratio, imgHeight * ratio); pdf.save('document.pdf'); }).catch(error => { console.error('PDF generation failed:', error); }); }

Real-World Example: Invoice Generation

Let’s walk through a practical example – generating PDF invoices from an ASP.NET Web Forms page. Here’s how I implemented it for a client billing system:

The HTML Structure

<div class="invoice-container"> <table class="header-table"> <tr> <td class="company-info"> <strong>Company Name</strong><br/> Address Line 1<br/> Address Line 2 </td> <td class="invoice-title"> # INVOICE<br/> Invoice #<span id="invoiceId">001</span><br/> Date: <span id="invoiceDate">2025-09-19</span> </td> </tr> </table> <table class="items-table"> <thead> <tr> <th>Description</th> <th>Amount</th> </tr> </thead> <tbody> <tr> <td>Software Development</td> <td>$1,500.00</td> </tr> <tr class="total-row"> <td><strong>Total</strong></td> <td><strong>$1,500.00</strong></td> </tr> </tbody> </table> </div>

The PDF Generation Function

function downloadInvoiceAsPDF() { // Hide UI elements that shouldn't appear in PDF const buttons = document.querySelectorAll('button, input[type="button"]'); buttons.forEach(btn => btn.style.display = 'none'); const element = document.querySelector('.invoice-container'); html2canvas(element, { scale: 2, useCORS: true, allowTaint: true, backgroundColor: '#ffffff' }).then(canvas => { const { jsPDF } = window.jspdf; const pdf = new jsPDF('portrait', 'mm', 'a4'); const imgData = canvas.toDataURL('image/png'); const pdfWidth = pdf.internal.pageSize.getWidth(); const pdfHeight = pdf.internal.pageSize.getHeight(); const imgWidth = canvas.width; const imgHeight = canvas.height; const ratio = Math.min(pdfWidth / imgWidth, pdfHeight / imgHeight); pdf.addImage(imgData, 'PNG', 0, 0, imgWidth * ratio, imgHeight * ratio); // Generate dynamic filename const invoiceId = document.getElementById('invoiceId').textContent; pdf.save(`invoice-${invoiceId}.pdf`); // Restore hidden elements buttons.forEach(btn => btn.style.display = ''); }); }

Best Practices and Tips

1. Optimize for PDF Output

CSS Considerations:/* Use print-friendly styles */ .invoice-container { font-family: Arial, sans-serif; color: #000; background: #fff; } /* Avoid these in PDF content */ .no-pdf { box-shadow: none; border-radius: 0; background-image: none; }

2. Handle Multi-Page Content

For content that spans multiple pages:function generateMultiPagePDF(element) { html2canvas(element, { scale: 2 }).then(canvas => { const { jsPDF } = window.jspdf; const pdf = new jsPDF(); const imgData = canvas.toDataURL('image/png'); const imgWidth = 210; // A4 width in mm const pageHeight = 295; // A4 height in mm const imgHeight = (canvas.height * imgWidth) / canvas.width; let heightLeft = imgHeight; let position = 0; // Add first page pdf.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight); heightLeft -= pageHeight; // Add additional pages if needed while (heightLeft >= 0) { position = heightLeft - imgHeight; pdf.addPage(); pdf.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight); heightLeft -= pageHeight; } pdf.save('multi-page-document.pdf'); }); }

3. Error Handling and User Feedback

Always provide feedback to users:async function generatePDFWithFeedback() { try { // Show loading indicator showLoadingSpinner(); const element = document.querySelector('.content'); const canvas = await html2canvas(element, { scale: 2 }); const { jsPDF } = window.jspdf; const pdf = new jsPDF(); const imgData = canvas.toDataURL('image/png'); pdf.addImage(imgData, 'PNG', 10, 10, 190, 0); pdf.save('document.pdf'); showSuccessMessage('PDF downloaded successfully!'); } catch (error) { console.error('PDF generation failed:', error); showErrorMessage('Failed to generate PDF. Please try again.'); } finally { hideLoadingSpinner(); } }

4. Testing Across Browsers

Different browsers may render content slightly differently. Test your PDF generation across:

• Chrome/Chromium-based browsers
• Firefox
• Safari
• Edge

Performance Considerations

Optimize image processing:

• Use appropriate canvas scale (2x is usually sufficient)
• Consider compressing images before PDF generation
• For large documents, implement progress indicators

Memory management:

• Clean up canvas elements after use
• Consider breaking very large documents into smaller chunks

Troubleshooting Common Issues

Problem: PDF is blank or elements are missing

• Check console for errors
• Ensure all external resources (fonts, images) are loaded
• Try reducing the canvas scale

Problem: Poor quality output

• Increase the canvas scale
• Use vector-friendly fonts
• Avoid complex CSS effects

Problem: CORS errors

• Use useCORS: true and allowTaint: true options
• Ensure all resources are served from the same domain or have proper CORS headers

Conclusion

Client-side PDF generation is a powerful technique that can enhance user experience while reducing server complexity. The jsPDF + html2canvas approach provides the best balance of reliability and control, especially during development on localhost.

While there are trade-offs compared to server-side solutions, the benefits of instant generation, privacy, and reduced infrastructure costs make it an excellent choice for many web applications.

Whether you’re building invoicing systems, generating reports, or creating certificates, these techniques will help you implement robust PDF generation that works reliably across different environments.

Italy operates a sophisticated vehicle registration system managed by the Ministry of Transport, covering over 39 million registered vehicles across the country’s 20 regions. The Italian Vehicle Registration API provides developers and businesses with access to comprehensive vehicle specifications, technical data, and insurance information for vehicles registered throughout Italy, from the industrial north to the southern regions.

Overview of Italian Vehicle Registration System

Italy’s vehicle registration system is centralized under the Motorizzazione Civile (Department of Motor Vehicles) and integrated with the PRA (Pubblico Registro Automobilistico – Public Automotive Registry). The system maintains detailed records for all vehicle types, from traditional cars to motorcycles, providing standardized identification across all Italian provinces.

The Italian license plate system has evolved over time:

• Current format (1994-present): Two letters + three numbers + two letters (AB 123 CD)
• Regional identification: Letters indicate the province of registration
• Special formats: Diplomatic, military, and temporary plates with distinct patterns

Italian Vehicle API Features

The Italy endpoint provides comprehensive vehicle information with focus on technical specifications and power ratings:

Available Data for Cars

When querying Italian car registrations, you can retrieve:

• Make and Model – Complete manufacturer and vehicle model identification
• Registration Year – Year when the vehicle was first registered in Italy
• Engine Specifications – Engine displacement and detailed power ratings
• Fuel Type – Fuel classification (Diesel, Benzina/Petrol, GPL, Metano, Electric)
• Technical Details – Version information, number of doors, ABS and airbag status
• Power Ratings – Multiple power measurements (CV, KW, Fiscal Power)
• VIN Number – Vehicle Identification Number when available
• K-Type Code – European vehicle type approval identifier

Sample Car Response Format

}

Motorcycle Support

Italy also provides dedicated motorcycle data through the CheckItalyMotorbike endpoint:

{
  "Description": "Ducati Monster 600 25KW - 34 CV",
  "RegistrationYear": "1999",
  "CarMake": {
    "CurrentTextValue": "Ducati"
  },
  "CarModel": {
    "CurrentTextValue": "Monster 600"
  },
  "MakeDescription": {
    "CurrentTextValue": "Ducati"
  },
  "ModelDescription": {
    "CurrentTextValue": "Monster 600"
  },
  "Version": "25KW - 34 CV"
}

Insurance Information Support

The Italian system also provides access to current insurance information through the CheckInsuranceStatusItaly endpoint:

<InsuranceDetails>
  <Company>IPTIQ EMEA P&C SA</Company>
  <Expiry>2025-01-23T00:00:00</Expiry>
  <IsInsured>true</IsInsured>
  <Region>VE</Region>
</InsuranceDetails>

API Implementation

Endpoint Usage

The Italian Vehicle API uses multiple endpoints:

1. Cars: /CheckItaly – For passenger vehicles and commercial vehicles
2. Motorcycles: /CheckItalyMotorbike – For motorcycles and scooters
3. Insurance: /CheckInsuranceStatusItaly – For insurance verification

All endpoints require:

• Registration Number – The complete Italian license plate number
• Username – Your API authentication credentials

France operates one of Europe’s most sophisticated vehicle registration systems, covering over 38 million registered vehicles across its 101 departments. The French Vehicle Registration API provides developers and businesses with access to comprehensive vehicle specifications, technical data, and registration information for vehicles registered throughout metropolitan France and overseas territories.

Overview of French Vehicle Registration System

France’s vehicle registration system is managed by the Ministry of the Interior through the National Secure Registration System (SIV – Système d’Immatriculation des Véhicules). Since 2009, France has used a standardized license plate format that includes two letters, three numbers, and two letters (AA-123-AA), replacing the older regional system.

The centralized system maintains detailed technical specifications for all registered vehicles, including data from:

• ANTS (Agence Nationale des Titres Sécurisés) – National Agency for Secure Documents
• UTAC-CERAM – Technical services for automotive certification
• SRA (Sécurité et Réparation Automobiles) – Automotive security and repair classifications

French Vehicle API Features

The France endpoint provides comprehensive vehicle information including technical specifications and security classifications:

Available Data

When querying French vehicle registrations, you can retrieve:

• Make and Model – Complete manufacturer and vehicle model identification
• Registration Year – Year when the vehicle was first registered in France
• Engine Specifications – Engine size, fuel type, and power ratings
• Technical Details – Transmission type, body style, and variant information
• Registration Date – Exact date of first vehicle registration
• SRA Classifications – Security and theft risk classifications
• CNIT Code – French National Vehicle Identification Code
• K-Type ID – European vehicle type approval identifier
• Environmental Data – CO2 emissions and cylinder count

Basic Implementation Example

// JavaScript example for French vehicle lookup
async function lookupFrenchVehicle(registrationNumber, username) {
  const apiUrl = `https://www.immatriculationapi.com/api/reg.asmx/CheckFrance?RegistrationNumber=${registrationNumber}&username=${username}`;
  
  try {
    const response = await fetch(apiUrl);
    const xmlText = await response.text();
    
    // Parse XML response
    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(xmlText, "text/xml");
    const jsonData = xmlDoc.getElementsByTagName("vehicleJson")[0].textContent;
    const vehicleInfo = JSON.parse(jsonData);
    
    return {
      make: vehicleInfo.MakeDescription.CurrentTextValue,
      model: vehicleInfo.ModelDescription.CurrentTextValue,
