Why Alibaba Cloud and Tencent Cloud Specifically

Trial credit conversion on English-language clouds has been written about many times, but for developers in China the real billing currency is the RMB account balance. Alibaba Cloud's Bailian / DashScope and Tencent Cloud's TI platform / Hunyuan API both sit inside the same account billing system. That means new-user trial credit does not need any cross-border migration: as long as the billing category matches, it can directly offset LLM inference charges.

This article deals with exactly one question: how to turn trial credit and vouchers from a newly registered account into callable LLM tokens.

Steps

Route 1: Alibaba Cloud new-user trial credit to Bailian / DashScope

  1. Register and complete personal or enterprise real-name verification. Unverified accounts cannot claim most new-user benefits or enable Bailian.
  2. Go to the free trial or new-user benefits page on the Alibaba Cloud site and browse by product category. Focus on two things: general vouchers (usable against postpaid bills) and model-service free quotas (usually expressed as millions of tokens or thousands of calls; exact amounts are shown live on the page).
  3. Enable the model service in the Bailian console and create an API key. Note that the Bailian console and the DashScope compatible mode are two separate entry points; the latter exposes an OpenAI-compatible protocol.
  4. In the billing center, read the scope of each voucher carefully. Some are restricted to ECS or a specific product. Only vouchers marked as usable for PAI, Bailian or model services can actually offset token bills.
  5. When calling, prefer model versions covered by the free quota (for example the lightweight and standard Qwen variants), spend the quota on validation and load testing, and switch to paid models only for production.

Route 2: Tencent Cloud new-user vouchers to TI platform / Hunyuan API

  1. Register with a WeChat or QQ account and complete real-name verification (personal verification is enough; enterprise verification usually unlocks higher amounts).
  2. Claim the new-user gift pack from the Tencent Cloud assistant or the voucher / coupon page in the console. The key is to distinguish cash vouchers (offset postpaid bills) from resource packs (bound to one product).
  3. Enable the service in the Tencent Cloud TI platform or the Hunyuan console and request an API key. Hunyuan offers an OpenAI-compatible endpoint, so integration cost is low.
  4. Check the applicable-products field on each voucher. Some Tencent Cloud vouchers are marked all-products, which is the easiest case and can directly offset Hunyuan API charges; product-restricted vouchers require you to confirm Hunyuan is on the list.
  5. If the trial credit cannot sustain long-term calling, spend it on offline batch processing: run the dataset once in bulk instead of keeping an always-on online service, so hourly-billed resources do not keep draining the credit.

Route 3: Merge both routes into one account pool

  1. Both clouds allow one verified entity per primary account. If you have both a personal and a company identity you can register separately, but the same real-name information cannot claim new-user benefits twice — this is the most commonly overlooked limit.
  2. Use LiteLLM or a similar OpenAI-compatible gateway and configure DashScope compatible mode and the Hunyuan compatible endpoint as two upstreams.
  3. Set routing and budget caps in the gateway so requests prefer the upstream that still has free quota and switch automatically when it runs out. This pools the trial credit into one continuous token supply.

Cautions

  • Expiry is the biggest trap. Cloud trial credit usually expires in 30 to 90 days, and some vouchers only start counting down after you activate them. Check the exact number of days on the claim page.
  • Free quota and vouchers are not the same thing. The former is a product-level quota pack, the latter a bill-level discount coupon. They stack, but priority and scope differ.
  • Regional limits. Some model services are only available in specific regions; cross-region calls may not count against free quota.
  • Verification and account merging. Multiple accounts under the same ID or business license usually entitle only one to new-user benefits; sub-accounts and RAM users generally cannot claim independently.
  • Do not run production traffic on trial credit. Once quota runs out, pay-as-you-go charges hit your account balance directly, so always set cost alerts and budget caps.
  • Compliance. All calls must follow the vendor's content safety and terms of service.

When to Use This

  • Individual developers who want to get Qwen or Hunyuan endpoints working without topping up first.
  • Small teams doing technical evaluation and comparing model quality and latency between the two clouds.
  • Projects that need stable LLM access from within mainland China and cannot use overseas APIs.
  • RAG and agent prototypes with short, bursty call patterns that fit the trial credit's validity window.

After the Credit Runs Out

Trial credit is only a starter. Once it is exhausted you can move to pay-as-you-go (with controlled cost), local open-source deployment (Ollama / vLLM), or a gateway that aggregates multiple upstreams to keep costs minimal.
