Set up DeepSeek
Researched from DeepSeek's official documentation on 2026-11-02. Not yet walked through end to end.
- Current: Sign in to the API platform
Use the API key link in DeepSeek’s official first-call guide to create or sign in to your platform account.
- Not started: Create an API key
Create a key for your application in the platform, and keep the full key in your own secret storage.
- Not started: Check balance and model access
Review your API balance, limits and currently supported model identifiers before configuring your local application.
- Not started: Configure your .env
Use the environment names below in your own application. Keep its environment file out of source control. Never paste a key into this website.
- Not started: Run the local check
Choose a model you can use and run the matching example below on your own machine. Check any applicable usage charges first.
This provider is available in PHP Prism. The TypeScript and Python ports do not implement it.
Configure and verify locally
Environment names and defaults below come from the installed package. Choose a model you can use by setting PRISM_SETUP_MODEL on your machine. Run the verification only when you are ready for one billed request. No request is sent by this page.
Approximate text cost is input tokens × your model’s input rate, plus at most 32 output tokens × its output rate, divided by the rate’s token unit. Add any provider fees. Check your model and region’s current price; the token limit is not a money cap.
use Prism\Prism\Facades\Prism;
// Run in your own configured Laravel app (for example, php artisan tinker).
$model = getenv('PRISM_SETUP_MODEL');
if (!$model) {
throw new RuntimeException('Set PRISM_SETUP_MODEL to your model.');

$result = Prism::text()
