How to Use Tencent Hy3 For Free (Open Source AI Guide)

jigz — Wed, 08 Jul 2026 16:41:06 +0000

So Tencent just launched Hy3, their newest open source AI model, and it brings some pretty interesting upgrades. If you are a developer, product engineer, or a founder trying to run an efficient workflow without burning a massive hole in your wallet, this is a model you definitely need to look at.

What makes this model special right out of the gate is that Tencent decided to ship the final version under a fully open Apache two point zero license. That means you can use it for commercial projects without jumping through legal hoops or worrying about restrictions. On top of that, they focused heavily on making it reliable for real world apps instead of just trying to chase high scores on arbitrary leaderboards. They actually cut the model's hallucination and common sense error rates right in half compared to the older preview versions. That makes it way more stable when you are trying to handle long, complex conversations or trying to force it to output strict data formats like clean JSON.

The Tech Under the Hood

Let us talk about how this thing is actually built. Hy3 uses a mixture of experts architecture. It has a massive two hundred and ninety five billion total parameters, but it only activates twenty one billion parameters at a time for any given token.

This is the sweet spot for modern open weights models. By only triggering a small slice of its total brain power at once, it stays incredibly fast and responsive while still giving you the deep reasoning and performance of a giant three hundred billion parameter model.

Tencent also packed a two hundred and fifty six k context window into this version. If you have ever tried to paste an entire coding file or a massive chunk of project documentation into a standard AI window only to hit a context wall, you know how annoying that is. With two hundred and fifty six k tokens, you can comfortably feed it large sections of your codebase or massive documents without the model losing its memory or getting confused halfway through.

Let us Look at the Benchmarks

To see how smart this model actually is, we can look at how it handles developer specific and agent driven tasks.

SWE-bench Pro: This benchmark tests how well an AI can jump into a real, complex GitHub repository and resolve actual software engineering issues. Hy3 scores fifty seven point nine percent here. That is a solid number that puts it right behind GLM five point two and keeps it competitive with top tier closed models.
Terminal Bench two point one: This is a tough benchmark that measures command line execution, bash scripting, and direct system control capabilities. Hy3 hits seventy one point seven percent on this test, which means it completely outperforms models like DeepSeek V4 pro when it comes to navigating a terminal and running system tasks.
MCP Atlas Public: This benchmark evaluates how well a model can interact with the Model Context Protocol, which is essential if you are building autonomous agents that need to use external tools, query databases, or call APIs. Hy3 scores seventy nine point one percent, beating out several major open source alternatives in the ecosystem.

The takeaway from the data is pretty clear. Tencent built this model specifically for builders who need a model that can write code, run terminal commands, and handle agentic tool workflows without constantly breaking down.

Where Can You Use It?

If you want to test Hy3 out for yourself, you have two great options depending on what kind of setup you prefer.

1. Tencent AI Studio

You can go straight to the official website at aistudio.tencent.com. This is Tencent's official developer platform. It gives you an easy way to test the model directly inside your web browser, read through the technical documentation, and manage your API keys if you want to build something directly inside their native cloud ecosystem.

2. OpenRouter

Another fantastic option is OpenRouter. They have already listed the model on their platform, making it incredibly easy to connect to your existing developer workflows and AI code editors. The best part is that you can use Hy3 completely for free on OpenRouter right now during its initial launch period.

What Happens When the Free Tier Ends?

Eventually, the promotional free tier on OpenRouter will wind down, and you will have to pay for the tokens you use. While the finalized official pricing for this specific version has not been fully locked in by Tencent yet, it will likely match the pricing structure of the preview version.

If it stays the same, the regular pricing will look like this:

Input Tokens: Zero point zero six three dollars per million tokens.
Output Tokens: Zero point twenty one dollars per million tokens.

When you break that down, cost wise, it is exceptionally budget friendly. Running a massive two hundred and ninety five billion parameter model for fractions of a penny per request is an incredible value, especially compared to the steep monthly subscription fees or high API costs of premium closed source alternatives.

Setting Up Hy3 in VS Code

If you want to take advantage of this free tier right now and bring Hy3 directly into your coding environment, setting it up in VS Code is incredibly straightforward.

First, you need to head over to the OpenRouter website, log into your account, and go to your dashboard to create a new API key. You can give it any description you want. For example, I am just going to name mine VS Code. Once the key is generated, copy it to your clipboard.

Next, open up your VS Code editor. You will want to open your model selection menu or your specific AI copilot extension settings. Look for the option that says manage models or configure providers. In this menu, you need to add OpenRouter as your active API provider. Hit enter, and then paste the API key that you just copied from your OpenRouter dashboard.

Once your key is connected, VS Code will pull in the available models. To keep your interface clean and fast, you can go ahead and hide all the unnecessary models you do not plan on using and keep only the models you want. For this setup, I am just going to keep Hy3 visible.

Finally, open your main model picker one more time and select Tencent Hy3. Now everything is fully connected and ready to go. You can open up your chat sidebar, highlight a piece of code, or use inline generation to ask it a question. When you test it out with a coding problem, you will see that it responds quickly, gives a really good answer, and handles debugging tasks incredibly well.

Final Thoughts

This approach gives you a completely free way to leverage a top tier open weights model directly inside your IDE. If you are tired of paying for expensive monthly premium copilot plans or you just want to experiment with alternative open source architectures that compete with the biggest names in the industry, Hy3 is worth adding to your stack.

Build a PDF to Image Converter in Next.js

jigz — Fri, 29 May 2026 16:38:00 +0000

This tutorial walks through the PDF to Images feature in a Next.js template. You'll learn how to use it from the UI, and how it works under the hood using browser-based PDF rendering and image export.

What This Tool Does

The PDF to Images tool converts every page of an uploaded PDF into one or more image files.

Supported output formats:

PNG — lossless, great for diagrams and documents with sharp lines
JPG — smaller file sizes, ideal for photographs and sharing

You can also control:

Quality for JPG output
DPI for rendering resolution

Step-by-Step User Tutorial

1. Open the PDF to Images tool

From the sidebar, select the PDF to Images tool.

2. Upload a PDF file

Use the upload area and drag or choose a PDF file.

The tool only accepts .pdf
You can upload one file at a time

3. Choose the output format

Select either PNG or JPG from the format dropdown.

PNG keeps image transparency and delivers crisp results.
JPG produces smaller files and uses white backgrounds automatically.

4. Set the quality and DPI

Adjust the sliders:

Quality controls JPEG compression.
DPI controls the rendering scale.

Higher DPI produces sharper images but uses more memory and takes longer.

5. Start conversion

Click the Convert to Images button.

The progress indicator updates while the pages are rendered one by one.

6. Preview converted pages

After conversion, the first page appears as a preview.

A list of all converted pages appears below, with download buttons for each image.

7. Download images

Use the Download All button to save all pages at once, or download individual images.

Each output file is named like:

document-page-1.png
document-page-2.jpg

How It Works Under the Hood

This is a Next.js implementation, where the interactive UI lives in a client component and the conversion helper lives in a shared lib module.

The feature is implemented in two main places:

components/tools/pdf-to-images-tool.tsx
lib/pdf-to-image-client.ts

1. Client-side app UI

pdf-to-images-tool.tsx handles:

Uploading the PDF file
Validating file type
Reading settings: output format, quality, DPI
Showing progress, preview, and download controls
Calling the conversion helper

When the user clicks Convert to Images, the tool calls:

const images = await convertPdfToImages({ file: sourceFile, format, quality, dpi, onProgress })

2. PDF rendering with `pdfjs-dist`

The actual conversion happens in lib/pdf-to-image-client.ts.

This file dynamically imports pdfjs-dist and sets up the worker like this:

const pdfjs = await loadPdfJs()
pdfjs.GlobalWorkerOptions.workerSrc = new URL('pdfjs-dist/legacy/build/pdf.worker.min.mjs', import.meta.url).toString()

Then it loads the PDF file and creates a document object:

const pdfData = await file.arrayBuffer()
const pdf = await pdfjs.getDocument({ data: pdfData }).promise

3. Rendering pages onto a canvas

The conversion loop renders each PDF page one at a time:

for (let pageNumber = 1; pageNumber <= pdf.numPages; pageNumber += 1) {
  const page = await pdf.getPage(pageNumber)
  const viewport = page.getViewport({ scale })
  const canvas = document.createElement('canvas')
  const context = canvas.getContext('2d', { alpha: format === 'png' })
  canvas.width = Math.ceil(viewport.width)
  canvas.height = Math.ceil(viewport.height)

  if (format === 'jpg') {
    context.fillStyle = '#ffffff'
    context.fillRect(0, 0, canvas.width, canvas.height)
  }

  await page.render({ canvas, canvasContext: context, viewport }).promise

  const blob = await new Promise<Blob>((resolve, reject) => {
    canvas.toBlob((result) => {
      if (!result) reject(new Error(...))
      resolve(result)
    }, mimeType, format === 'jpg' ? normalizedQuality : undefined)
  })
}

Key details:

viewport is scaled by dpi / 72
canvas.toBlob() converts the rendered page into PNG or JPG data
For JPG, the code first paints a white background because JPEG does not support transparency

4. Exporting images as downloadable files

Each rendered page becomes a Blob, which is converted into a browser object URL:

function createObjectUrl(blob: Blob) {
  return URL.createObjectURL(blob)
}

That URL is stored and later used for preview and downloads.

5. Downloading files

The UI uses this helper to trigger downloads:

export function downloadObjectUrl(url: string, fileName: string) {
  const link = document.createElement('a')
  link.href = url
  link.download = fileName
  document.body.appendChild(link)
  link.click()
  document.body.removeChild(link)
}

This creates a temporary anchor tag and simulates a click so the browser downloads the image.

6. Cleaning up memory

After conversion, object URLs are revoked to free browser memory:

export function revokeConvertedImages(images: ConvertedPdfImage[]) {
  images.forEach((image) => URL.revokeObjectURL(image.url))
}

This is important because every converted page creates an in-memory image blob.

Practical Notes

Best settings for quality and speed

PNG is best for text, charts, and sharp document pages
JPG is best for smaller downloads and photographic PDF content
DPI 150 is a solid default: good sharpness without excessive memory use
If your PDF is large, convert only what you need or split it first

Why this approach is powerful

It runs entirely in the browser
No server upload or backend processing is required
Files stay private on the user’s device
The experience is instant and responsive

Example Next.js Workflow

Open the PDF to Images tool in the app
Upload report.pdf
Choose JPG
Set quality to 85%
Use DPI 150
Click Convert to Images
Preview the first page
Click Download All

You now have one image file per page, ready for use in presentations, websites, or screenshots.

Where This Lives in the Template

Component: components/tools/pdf-to-images-tool.tsx
Conversion helper: lib/pdf-to-image-client.ts
Tool entry in config: lib/tools-config.ts
Route mapping: app/tools/[id]/page.tsx

If you want to modify the feature, those are the files to edit.

Summary

This PDF to Images feature is a great example of how a Next.js app turns browser APIs into a real product capability. It combines pdfjs-dist rendering, canvas export, and browser downloads to give you a fast, client-side PDF conversion feature without any backend.

I Built a File Utility Tool for PDFs, Images & OCR

jigz — Fri, 29 May 2026 16:04:09 +0000

I remember the exact moment it clicked. I was watching a friend fork over $14.99 for a monthly iLovePDF subscription just to merge a few PDF files and compress a handful of images. They used the service for maybe 5 minutes total and didn't touch it again for weeks.

That same month, I noticed a constant stream of the same burning questions across various online communities:

"Is there a free way to convert my PDFs to images?"
"How can I compress these photos without losing quality?"
"I need to split this massive PDF but I don't want to pay."

It hit me hard: companies were making serious money by putting a paywall around relatively simple file operations that have been technically possible for years. The standard industry pricing? $10-15 per month for tools that do exactly what I knew I could build myself.

So, I decided to do something about it. I built File Craft—a completely free, lightning-fast, and user-friendly file processing application that puts an end to expensive subscriptions. I'm releasing it to the world so everyone can stop paying for tools that should be entirely free.

What is File Craft?

File Craft is a modern, all-in-one file processing suite that runs entirely in your browser. It completely eliminates subscriptions, watermarks, data tracking, and artificial limits (outside of your own browser's memory).

Core Capabilities

📄 PDF Tools

✂️ Split PDFs: Extract specific pages or divide massive PDF documents into smaller chunks.
🔗 Merge PDFs: Effortlessly combine multiple PDFs into a single document (up to 50 files at once!).
🗜️ Compress PDFs: Drastically reduce file sizes while maintaining professional visual quality.
📸 Convert PDFs to Images: Instantly transform PDF pages into high-quality JPG or PNG files.

🖼️ Image Tools

🖼️ Compress Images: Minimize image file sizes without sacrificing your visual clarity.
🎨 Convert Images: Seamlessly transform formats between JPG, PNG, WebP, and more.
📏 Resize Images: Scale images to exact custom dimensions or use optimized social media presets.
👁️ Extract Text (OCR): Utilize advanced optical character recognition to digitize scanned documents and text within images.

Why I Built It (Besides Being Tired of Paying)

The inspiration behind File Craft goes deeper than just my frustration with predatory pricing models:

Accessibility: Vital file processing tools shouldn't be gatekept behind a paywall. Whether you are a student, a freelancer, or just someone who occasionally needs to edit a document, you shouldn't be forced into a monthly subscription.
Absolute Privacy: Most online SaaS tools require you to upload files to their servers, raising valid security and privacy concerns. With File Craft, everything runs entirely client-side. Your files never leave your device.
Blazing Speed: Say goodbye to upload bottlenecks and server processing queues. Because it operates locally in your browser, execution happens almost instantly.
The Engineering Challenge: I wanted to push my technical boundaries. Engineering a browser-based application that seamlessly handles heavy PDF manipulation, image processing, and OCR forced me to master complex web APIs and intricate file structures.
Community Impact: I wanted to contribute something genuinely useful. If File Craft saves a single user $10 a month, that's $120 saved a year. Multiplied across thousands of users, that is a massive, tangible impact.

The File Craft Solution: Upload up to 50 PDFs at a time, arrange them in any sequence using an intuitive drag-and-drop interface, and merge them instantly for a one-click download.
Why It Matters: Most commercial tools charge users per merge operation. File Craft allows unlimited merges without ever asking for a credit card.

Split PDFs

The Problem: You have a massive 50-page document but only need pages 10–15, or you need to divide a single document into individual files.
The File Craft Solution: Upload your PDF and choose your strategy: extract exact custom page ranges (e.g., 1-5, 10-15) or split the document evenly by specifying the desired number of files.
Why It Matters: Paid platforms love to charge per transaction. Split your files as many times as your workflow demands.

Compress PDFs

The Problem: Your PDF file size is too massive to attach to an email or upload to a state portal, but you cannot afford to lose readability.
The File Craft Solution: Upload your file and pick your compression tier: Low (maximum quality), Medium (the recommended sweet spot), or High (smallest possible footprint). You even get a real-time size comparison before processing.
Pro Tip: Modern digital PDFs compress remarkably well, meaning you can often achieve massive space savings with zero visible quality loss.

PDF to Images

The Problem: You need to extract specific PDF pages as standalone images to use in slide decks, websites, or digital archives.
The File Craft Solution: Upload the PDF, select your output format (JPG or PNG), choose your quality profile (Low, Medium, High), define your page range, and instantly extract them.
Why It Matters: Skip the per-conversion paywalls found elsewhere. Convert entire books into image strings effortlessly.

🖼️ High-Performance Image Toolkit

How to Download Your Entire Supabase Storage Bucket Locally

jigz — Sun, 03 May 2026 09:23:02 +0000

If you've been building with Supabase, you know their Storage API is fantastic for web apps. But sometimes, you just need your files on your local machine—whether for a manual backup, bulk editing, or migrating data.

While you could write a script using the Supabase SDK, there is a much faster, "no-code" way to manage your files like a Pro: Cyberduck.

Note: Cyberduck is an official Supabase partner integration. It is a secure, open-source tool that Supabase explicitly recommends for managing storage via the S3 protocol. You can find the official integration page here.

Phase 1: Generate Your S3 Credentials

Before opening Cyberduck, you need to give it permission to talk to your Supabase project via the S3 protocol.

Log in to your Supabase Dashboard.
Navigate to the S3 Settings tab in the sidebar (under Storage).
Under Access Keys, click Create Access Key.
Give it a description (e.g., "Local Backup") and click Create.
Important: Copy your Access Key ID and Secret Access Key immediately. You won't be able to see the secret again!

Phase 2: Configure the Cyberduck Profile

Cyberduck needs a specific "handshake" configuration to understand Supabase’s structure.

Download Cyberduck: Get the latest version from their official download page.
Create the Profile: Create a file on your computer named supabase.cyberduckprofile.
Paste the following code into that file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Protocol</key>
        <string>s3</string>
        <key>Vendor</key>
        <string>Supabase Storage S3</string>
        <key>Scheme</key>
        <string>https</string>
        <key>Description</key>
        <string>Supabase Storage (S3)</string>
        <key>Default Hostname</key>
        <string>YOUR_PROJECT_REF.supabase.co</string>
        <key>Default Port</key>
        <string>443</string>
        <key>Region</key>
        <string>YOUR_REGION</string>
        <key>Properties</key>
        <array>
            <string>s3.storage.class.options=STANDARD</string>
            <string>s3.bucket.virtualhost.disable=true</string>
        </array>
        <key>Context</key>
        <string>/storage/v1/s3</string>
    </dict>
</plist>

Edit the file: Replace YOUR_PROJECT_REF with your project ID (found in your Supabase URL) and YOUR_REGION (e.g., ap-south-1).
Save and Run: Double-click the file. Cyberduck will open and ask for your credentials. Enter the Access Key ID and Secret Access Key you generated earlier.

Phase 3: Downloading Your Bucket

Once connected, you will see your Supabase buckets listed just like folders on your computer.

Select your Bucket: Locate the folder you wish to bring local.
Download: Right-click the bucket and select Download. You can choose the destination folder on your machine, and Cyberduck will handle the transfer.
Sync/Mirror: If you want to keep your local folder updated with the latest changes from the cloud without re-downloading everything, use the Mirror feature. This compares the local and remote folders and only transfers the differences.

Other Powerful Use Cases

Connecting via S3 is about more than just backups. Here’s what else you can do:

Bulk Uploads: Drag and drop thousands of assets (like product images or icons) directly into Supabase. It’s much more stable than using a browser-based dashboard for large volumes.
Direct Media Editing: Some editors allow you to open a file directly from Cyberduck, edit it, and save it back to the cloud instantly.
Cross-Cloud Migration: If you are moving files from AWS S3 or Cloudflare R2 into Supabase (or vice-versa), you can open two windows in Cyberduck and simply drag-and-drop between the two services.
Infrastructure Testing: It's an excellent way for developers to verify that their S3 policies and IAM-style permissions are working correctly before writing a single line of frontend code.

What is GEO (Generative Engine Optimization)? How to Implement It in Next.js

jigz — Wed, 25 Mar 2026 12:52:35 +0000

If you search something today, you’ll notice a shift.

Instead of just showing links, search tools are now giving direct answers. Tools like ChatGPT, Perplexity, and Google AI Overviews generate responses instead of listing pages.

Those answers come from somewhere.

That’s where GEO comes in.

What is GEO?

GEO stands for Generative Engine Optimization.

It means structuring your content so AI tools can understand it and use it inside their generated answers.

Earlier, the goal was to rank on search engines.

Now, the goal is to be part of the answer itself.

So instead of optimizing just for clicks, you’re optimizing for visibility inside AI responses.

Why GEO Matters

When someone asks a question to an AI tool, they usually get a complete answer instantly.

Most users don’t click further.

If your content is not included in that answer, it doesn’t get seen.

That’s the main shift.

It’s no longer just about ranking. It’s about being referenced.

How GEO is Different

Traditional SEO focuses on ranking pages.

GEO focuses on clarity and structure.

AI systems don’t care about keyword stuffing. They care about how clearly you explain something.

The better your explanation, the higher the chance it gets picked.

How to Implement GEO in Next.js

You don’t need complex setups. Most of it comes down to how you write and structure content.

Here’s how you can do it.

1. Add Structured Data (JSON-LD)

Structured data helps machines understand your content.

export default function Page() {
  const schema = {
    "@context": "https://schema.org",
    "@type": "SoftwareApplication",
    "name": "Your App Name",
    "description": "Short explanation of what your app does",
    "applicationCategory": "DeveloperApplication",
    "offers": { "@type": "Offer", "price": "0" }
  }

  return (
    <>
      <script
        type="application/ld+json"
        dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }}
      />
    </>
  )
}

2. Write Answer-First Content

Start with the answer.

Don’t delay it with long introductions.

AI tools prefer content that gives clear, direct answers immediately.

3. Use FAQ Sections

FAQ format works well because it matches how people ask questions.

const faqs = [
  {
    q: "How do I generate a PDF in Next.js?",
    a: "You can use Puppeteer or jsPDF depending on your use case."
  }
]

4. Add llms.txt

Create a simple file in your public folder:

# Your Website

> Short explanation

## Features
- Feature one
- Feature two

## Use cases
- Example one
- Example two

This helps AI tools understand your site faster.

5. Create “What is” and Comparison Content

Write content that answers real questions.

Examples:

What is something
How something works
Comparison between tools

This is exactly what AI tools look for.

6. Use Static Generation

Make your pages easy to crawl.

export async function generateStaticParams() {
  return posts.map((p) => ({ slug: p.slug }))
}

7. Keep Language Simple

Write like you speak.

Avoid complex words and long sentences.

Clear and simple explanations work better.

What Actually Matters

A few things make the biggest difference:

Clear answers at the start
Simple language
Structured content
Real examples

You don’t need tricks. You need clarity.

Final Thoughts

GEO is not replacing SEO.

It’s building on top of it.

Search is moving toward answers instead of links.

That changes how content gets discovered.

If your content explains things clearly, it has a higher chance of being used.

That’s the core idea.
