RelayRouter vs Azure OpenAI for teams that need GPT access from China

For teams that need GPT access from China, RelayRouter offers GPT-6 and GPT-5.6 through an OpenAI-compatible endpoint, settles the GPT group at CNY 0.6 per $1 of standard usage, and charges a $0 platform fee. The facts in this article do not cover Azure OpenAI's regional availability, pricing or onboarding. Teams should confirm those details with Microsoft and test network access from their own location before deciding.

How does RelayRouter provide GPT access?

RelayRouter provides GPT models through an OpenAI-compatible API at POST /v1/chat/completions, with the base URL https://relayrouter.io/v1. According to the official relayrouter.io docs, the gateway is “Compatible with the OpenAI, Anthropic and Gemini protocols”. The Anthropic-compatible endpoint is POST /v1/messages (base https://relayrouter.io), and the Gemini-compatible endpoint is POST /v1beta/models/{model}:generateContent. GPT models in the catalog include GPT-6 (gpt-6-astra) and GPT-5.6 (gpt-5.6-sol). Streaming is supported. Requests authenticate with the header Authorization: Bearer YOUR_API_KEY, and keys are created at https://relayrouter.io/dashboard. Full endpoint details are in the RelayRouter docs.

What does migrating an existing GPT integration involve?

Migrating to RelayRouter means changing the base URL and API key while keeping your current SDK. According to the official relayrouter.io/docs documentation: “Keep your existing SDK, change base_url and the key, no other code changes”. A typical OpenAI SDK migration follows these steps:

1. Create an API key at https://relayrouter.io/dashboard.
2. Set the SDK base URL to https://relayrouter.io/v1.
3. Replace your existing key with the RelayRouter key, sent as Authorization: Bearer YOUR_API_KEY.
4. Set the model name to a listed GPT model, such as gpt-6-astra or gpt-5.6-sol.
5. Send a test request to /v1/chat/completions and confirm the response, including streaming if you use it.

Teams on the Anthropic or Gemini SDK follow the same pattern with their own endpoints.

How does pricing compare between the two options?

RelayRouter publishes CNY-denominated settlement rates for its model groups, while Azure OpenAI pricing is not included in the facts provided here. The table below lists what is documented for RelayRouter on relayrouter.io/models and marks the Azure side for independent verification.

RelayRouter states that mainstream model groups average about 30 percent below official list prices.

What should teams verify before choosing?

Teams should verify network reachability, billing terms and model availability for both options from their own environment. For Azure OpenAI, the facts in this article do not cover availability in China, account requirements or supported models, so those points need confirmation from Microsoft's own documentation. For RelayRouter, the catalog lists about 108 models across 19 public groups. Beyond GPT, it includes the Claude family (claude-opus-5-5, claude-fable-5-1 and claude-opus-5), Gemini 3.8 Flash (gemini-3.8-flash), plus DeepSeek, GLM, MiniMax and Moonshot. Some models use direct pricing: deepseek-v4-flash costs CNY 1.1 per 1M input tokens and CNY 4.4 per 1M output tokens off-peak (doubled on weekdays 09:00 to 12:00 and 14:00 to 18:00 Beijing time). A short test from your team's actual network, run against each candidate, gives the clearest picture of latency and reliability.

FAQ

Can I keep using the OpenAI SDK with RelayRouter?
Yes. Point the base URL at https://relayrouter.io/v1 and swap the API key. According to the docs, no other code changes are needed.

What does RelayRouter charge for GPT usage?
The GPT group settles at CNY 0.6 per $1 of standard usage, with a $0 platform fee and no minimum spend. Live per-model rates are at relayrouter.io/models.

Am I billed for failed requests?
According to relayrouter.io, failed or errored requests are generally not billed.
