How to Try DeepSeek V4, Qwen and GPT-5 for Free via TokenPAPA

One of the biggest frustrations when evaluating AI APIs is the commitment required. Most providers ask for a credit card upfront, minimum spend commitments, or complex approval processes — all before you have written a single line of code against their API.

TokenPAPA takes a different approach: free credits on signup, no credit card required, test any model immediately.

Here is exactly how to get started.

Step 1: Sign Up (30 seconds)

Go to tokenpapa.ai
Click "Sign Up" — you only need your email address
Verify your email

No Chinese phone number required. TokenPAPA is built for overseas developers. Signup takes about 30 seconds.

Step 2: Receive Your Free Credits

Immediately after verifying your email, free credits are added to your account. No credit card information needed — you can start evaluating models with zero financial commitment.

The free credits are enough to:

Run 500+ chat completions on DeepSeek V4 Flash
Generate 50+ pages of content with Qwen 3
Test GPT-5 and Claude integration with your existing codebase
Compare model performance across 10+ providers

Step 3: Generate Your API Key

From the dashboard, click "Create API Key." Copy the key — this is your single credential for all models. No separate keys for different providers.

Step 4: Make Your First API Call

TokenPAPA uses the OpenAI-compatible format, so any existing OpenAI SDK code works with a two-line change:


client = openai.OpenAI(
    base_url="https://api.tokenpapa.ai/v1",
    api_key="your-tokenpapa-key"
)

# Try DeepSeek V4 Flash
response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain how free trial credits work in 3 sentences."}
    ]
)
print(response.choices[0].message.content)

If you are using Node.js, the same approach works:


const client = new OpenAI({
  baseURL: 'https://api.tokenpapa.ai/v1',
  apiKey: 'your-tokenpapa-key',
});

const response = await client.chat.completions.create({
  model: 'deepseek-v4-flash',
  messages: [{ role: 'user', content: 'Hello, what models can I try?' }],
});
console.log(response.choices[0].message.content);

And with curl:

curl https://api.tokenpapa.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-tokenpapa-key" \
  -d '{
    "model": "deepseek-v4-flash",
    "messages": [{"role": "user", "content": "Which models are available for free trial?"}]
  }'

What You Can Test with Free Credits

Your free credits work across every model on the platform. Here is what 100 free credits gets you in terms of model calls:

Model	Approximate Free Calls
DeepSeek V4 Flash	~700 completions
DeepSeek V4 Pro	~125 completions
Qwen 3 Max	~280 completions
MiniMax T2	~400 completions
GLM-4 Plus	~350 completions
GPT-5.4 Mini	~250 completions
Claude 4 Haiku	~100 completions

What to Test During Your Trial

1. Model Quality Comparison

Run the same prompt across DeepSeek V4 Flash, Qwen 3, GPT-5 Mini, and Claude Haiku. Compare outputs for:

Reasoning accuracy
Code generation quality
Chinese vs English language handling
Response speed

2. Latency Benchmarks

Test time-to-first-token for each model. TokenPAPA provides real-time latency metrics in the dashboard so you can identify which models perform best for your use case.

3. Fallback Configuration

Try building a multi-provider fallback chain — if one model is slow or unavailable, your code automatically retries with another. Since all models use the same API format, implementing fallbacks is straightforward:

models = ["deepseek-v4-flash", "qwen-3-120b", "gpt-5.4-mini"]

for model in models:
    try:
        response = client.chat.completions.create(
            model=model,
            messages=[{"role": "user", "content": prompt}],
            timeout=10
        )
        print(f"{model}: {response.choices[0].message.content}")
        break
    except Exception:
        continue

When You Are Ready to Continue

When your free credits run out, you have options:

Pay-as-you-go — no minimum spend, no subscription. Top up any amount and pay only for what you use.
Monitor your usage — the dashboard shows real-time token consumption and cost. No surprise bills.
Set spending limits — configure alerts and hard caps so you never exceed your budget.
