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

Why use Yi?

A focused page for evaluating this model as an API route, not just reading a catalog row.

Bilingual output

Useful for Chinese-English content, rewriting and assistant workflows.

Open ecosystem

A familiar model family for teams that have already tested Yi variants.

Gateway stability

Keep the same SmarToken endpoint while admins adjust upstream Yi-compatible routes.

Why SmarToken

Why not direct vendor accounts?

Direct accounts can work once region, billing, model IDs and credentials are settled. SmarToken is built for faster overseas evaluation and safer early production.

Unified key

One console key reaches mainstream Chinese model routes including DeepSeek, Kimi, Qwen, Hunyuan, MiniMax and Spark.

English docs

Model IDs, SDK samples and error semantics are written for overseas teams.

Budget control

Daily, monthly and model-family limits keep experiments predictable.

Route visibility

Usage logs connect model, API key, token estimate, latency and wallet debit.

How do I call Yi Large with OpenAI SDK?

Use baseURL https://thesmartoken.com/v1, set your SmarToken key and send model: yi-large.

Is Yi still worth listing next to newer Chinese models?

Yes for teams maintaining Yi-compatible workflows or comparing bilingual writing and structured output across model families.

Use cases

Popular use cases

Start with a clear workload, then compare routes in Playground before moving traffic into production.

Bilingual writing

Generate and rewrite Chinese-English product and business content.

Structured output

Extract fields, classify text and produce JSON-like replies.

Coding support

Use Yi as an alternate route for code explanation and snippets.

General assistant

Evaluate everyday chat, summary and drafting tasks.

Migration

From your current AI gateway

The integration path stays familiar: same Chat Completions shape, one new baseURL and a China-first model ID.

Switch path

From OpenAI

Keep the SDK. Change baseURL to SmarToken and switch the model ID.

Switch path

From OpenRouter

Move from broad routing into a focused Chinese-model console with budgets.

Switch path

From Together.ai

Keep Chat Completions while adding China-first model pages and route control.

FAQ

Questions developers ask

How do I call Yi Large with the OpenAI SDK?

Use the standard OpenAI SDK, set baseURL to https://thesmartoken.com/v1, authenticate with your SmarToken key, and pass model: yi-large.

What is Yi Large best for?

Yi Large is a good candidate for bilingual generation, structured outputs and general assistants. Test it in the Playground before routing production traffic.

How does Yi Large compare with Qwen and GLM?

Use the comparison table as a starting point, then run your own prompts because coding, reasoning, latency and cost can vary by upstream route.

Is this API compatible with the OpenAI SDK?

Yes. Use your SmarToken key, set baseURL to https://thesmartoken.com/v1, and pass the model ID shown on this page.

How is billing calculated?

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.

Where do I get an API key?

Create an account, open the console, generate an API key, then copy the cURL, Python or TypeScript example from the Playground.

Can I restrict one key to this model family?

Yes. Console API keys can be limited by allowed model family plus daily and monthly USD budgets.
