Best use cases and caveats

Caveats
- GLM 5.2 outperformed it overall in this benchmark.
- Use as a fallback or comparison route rather than the default first pick.
How to use this page
Score interpretation and guardrails
Weaknesses
Do not rely on the overall score alone. Review low tag scores, provider availability, fallback behavior, and task-specific failure modes before production.
Guardrails
Keep model names configurable, log request IDs and latency, and require human review for high-risk agent actions such as shell commands, file changes, and deploy operations.
OpenAI-compatible request
Use GPTokens with existing SDKs
import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.GPTOKENS_API_KEY,
baseURL: "https://gptokens.ai/v1"
});
const response = await client.chat.completions.create({
model: "glm-5.1",
messages: [{ role: "user", content: "Compare Chinese LLM routes for my task." }]

FAQ
Questions developers ask before buying Chinese LLM tokens
Is GPTokens run by a model provider?
No. GPTokens is an independent OpenAI-compatible gateway. It issues GPTokens API keys and routes requests to supported Chinese LLM providers through one account.
Can I use an OpenAI SDK?
Yes. Most integrations only need the GPTokens base URL, a GPTokens API key, and a supported model name from the live model list.
Who is this for?
GPTokens is built for developers and teams in the US, Europe, and other global markets that want to test Chinese LLM APIs without managing separate provider accounts, payment methods, and dashboards.
