35.AIGCBEST Review: Pricing & Comparison

Why an OpenAI-focused relay is worth considering

A do-everything lineup (covering Claude+GPT+Gemini+DeepSeek all in one place) is the strategy most relays pursue, but a focused, single-vendor relay has its own logic:

The benefits of focus: operational effort isn’t spread thin, so the platform can respond faster to changes in the OpenAI API; it can develop a deeper understanding of the discount structure within OpenAI’s pricing system; and it’s easier to sustain a cost advantage specifically on OpenAI.

35.AIGCBEST is exactly this kind of OpenAI-focused relay platform (domain 35.aigcbest.top, simple and direct). For developers who primarily use the OpenAI series and have no need for Claude/Gemini, a focused platform is often a better fit than a do-everything one.

What the Azure pricing structure means

35.AIGCBEST uses an Azure pricing structure.

Microsoft Azure is OpenAI’s largest partner. Azure OpenAI Service and a direct OpenAI connection are interface-compatible in most scenarios, but they differ in stability, compliance, and regional availability. An Azure-backed backend is generally more stable than an individually-run relay node, since Azure itself is enterprise-grade cloud infrastructure.

For end users, this means 35.AIGCBEST’s baseline stability is relatively well assured, rather than depending on a single individually-maintained node.

OpenAI models covered

35.AIGCBEST’s primary coverage:

• GPT-5.5: the current flagship text-generation model
• The o-series reasoning models: o3, o4-mini, and more, suited to tasks that need deep reasoning
• GPT-4o: multimodal, supports image understanding

The ~1.5¥/USD exchange rate applies to all of these models. Defer to 35.aigcbest.top’s official site for live pricing.

Who it fits

Best fit: developers already deeply invested in the OpenAI ecosystem (GPT API, Function Calling, the Assistants API, etc.), who don’t need Claude/Gemini and are looking for a more cost-effective OpenAI relay channel.

Poor fit: use cases needing flexible switching between multiple model families, needing Claude’s long-context capability, or chasing the absolute lowest price (platforms in the 0.6-1¥/USD range are cheaper).

Integration flow and code examples

35.AIGCBEST is fully compatible with the OpenAI SDK — integration only requires changing two things:

from openai import OpenAI

client = OpenAI(
    api_key="your 35.AIGCBEST API key",
    base_url="https://api.35.aigcbest.top/v1"  # check the official site for the current endpoint
)

# GPT-5.5 text generation
response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[
        {"role": "user", "content": "Help me write a product description"}
    ]
)

# o4-mini reasoning model
response = client.chat.completions.create(
    model="o4-mini",
    messages=[
        {"role": "user", "content": "Solve this math problem..."}
    ]
)

Frameworks like LangChain and LlamaIndex likewise only need the openai_api_base parameter replaced — the rest of the code stays the same.

The Azure pricing structure: what it actually means

35.AIGCBEST provides models through Azure OpenAI Service rather than directly reselling the OpenAI API. What this difference means for users:

Stability: Azure OpenAI runs on Microsoft’s enterprise infrastructure with an assured SLA, not dependent on an individually-run node. Compared to a self-built relay, an Azure-backed backend has a lower chance of disconnection.

Pricing: Azure OpenAI’s official price is close to the direct OpenAI API price; 35.AIGCBEST converts that at roughly 1.5¥/USD and sells it with a markup. For Chinese users, this eliminates the hassle of foreign-currency payment, with transparent pricing.

Model versions: Azure’s models sometimes launch slightly later than the direct OpenAI API, but usually sync up within a few days. Worth keeping in mind if your use case needs the very latest model.

Main OpenAI models covered

35.AIGCBEST focuses on the OpenAI ecosystem; its main models include:

• GPT-5.5: flagship text generation, supports image understanding (multimodal)
• o3 / o4-mini: reasoning-specialized, suited to math, logic, and code analysis
• GPT-4o: a versatile model balancing speed and capability
• Embeddings series: text-embedding-3-large and more, suited to RAG systems

35.AIGCBEST doesn’t provide non-OpenAI models (Claude, Gemini, etc.) — look elsewhere if you need those.
