LingModel (built-in)

The easiest way to get started. No API key, no setup, free to use. LingModel is a managed AI service built into LingCode.

What is LingModel?

LingModel is a built-in AI provider managed by LingCode. It powers all the quick-start examples, the "Try:" templates, and is the default when you first open the playground. You don't need:

An API key
A separate account
A payment method (for the free tier)
Any configuration

Just open the playground and start building.

Free tier vs. paid tier

Free Tier: 100 queries per month. Perfect for learning, experimenting, and casual use.

Paid Tier: Unlimited queries. Pay-as-you-go or subscribe for higher limits. Sign in to see your quota and upgrade options.

Getting started: Use the free tier to learn LingCode and build a few projects. When you're ready for unlimited access or need priority support, sign in and upgrade.

Using LingModel

Open the playground

Go to /try.html. LingModel is already selected as the default provider.

Type a prompt

Click in the text area and describe what you want to build:

"Build a landing page for an AI startup"
"Create an analytics dashboard"
"Make a business proposal template"

Click "Send" and wait

LingModel will generate your design in real-time. You'll see the HTML render in the preview pane as it streams in.

Download your creation

Once done, click the three-dots menu and choose:

Download .html to save as a file
Export PDF to print or share
Export PPT (if your design has slides)

Free tier limits

On the free tier, you get 100 queries per month. A "query" is one prompt + any follow-up "Continue" requests.

Examples of usage:

1 pitch deck prompt = 1 query
1 pitch deck + 3 refinements ("make it darker," "add a pricing slide," etc.) = 4 queries
10 different small designs = 10 queries

Running low? You'll see a warning when you're near your limit. You can:

Wait until next month for a fresh 100 queries
Sign in and upgrade to paid tier for unlimited access
Switch to another provider (Claude, DeepSeek, GPT-4) if you have API keys set up

Tip: For learning, 100 queries per month is usually plenty. That's ~3 designs per day. Switch to paid when you're actively building.

When to upgrade to paid

Consider upgrading your LingModel account if:

You consistently run out of free queries each month
You want unlimited builds without worrying about your quota
You need priority support or faster processing
You want to use LingModel on the LingCode Mac app (coming soon)

To upgrade:

Click the "Sign in" button in the top-right corner of the playground
Create a LingCode account or log in
Navigate to your account settings and select a plan
Add a payment method

Using other providers instead

If you want unlimited builds without upgrading LingModel, you can use other providers:

Claude (Anthropic): Set up an API key for Claude and pay per-query directly to Anthropic
DeepSeek: Cheaper than Claude, great for quick builds
GPT-4: Balanced quality and speed

See the tutorials for Claude, DeepSeek, and OpenAI to get started with these providers.
