}Fast Deployment
Generate a key and run the Playground in minutes.
Global Access
Use one endpoint for configured China-first routes.
Unified Billing
Track USD token usage and wallet debits together.
Easy Migration
Keep OpenAI SDK shape, change baseURL and model.
Developer Friendly
Copy-ready cURL, Python and TypeScript examples.
Model fit
A focused page for evaluating this model as an API route, not just reading a catalog row.
Supplier capabilities described here do not mean every feature is supported by this gateway. Current support is text Chat Completions; tools, structured output and multimodal requests are rejected. Review the gateway contract.
Use DeepSeek V4 Pro for research through one SmarToken API key.
Use DeepSeek V4 Pro for coding through one SmarToken API key.
Use DeepSeek V4 Pro for document analysis through one SmarToken API key.
Route fit
Treat deepseek-v4-pro as a route to test against a workload, not just a catalog name.
DeepSeek V4 Pro is strongest for research, coding. Validate it with real prompts before making it a default route.
If your workload depends more on long context, structured output or lowest cost, compare DeepSeek V4 Pro with neighboring model families.
Availability depends on the configured upstream route.
Why SmarToken
Direct accounts can work once region, billing, model IDs and credentials are settled. SmarToken is built for faster overseas evaluation and safer early production.
One console key currently reaches DeepSeek V4 Flash and V4 Pro. Other model families are coming soon.
Model IDs, SDK samples and error semantics are written for overseas teams.
Daily, monthly and model-family limits keep experiments predictable.
Usage logs connect model, API key, token estimate, latency and wallet debit.

Migration
The integration path stays familiar: same Chat Completions shape, one new baseURL and a China-first model ID.
Switch path
Keep the SDK. Change baseURL to SmarToken and switch the model ID.
Switch path
Move from broad routing into a focused Chinese-model console with budgets.
Switch path
Keep Chat Completions while adding China-first model pages and route control.
FAQ
Yes. Use your SmarToken key, set baseURL to https://thesmartoken.com/v1, and pass the model ID shown on this page.
Input and output tokens are priced separately in USD per 1M tokens. Final usage is recorded after the provider returns a response or a stream finishes.
Create an account, open the console, generate an API key, then copy the cURL, Python or TypeScript example from the Playground.
Yes. Console API keys can be limited by allowed model family plus daily and monthly USD budgets.
