Community benchmark logs from Chinese ISP endpoints recorded an average latency of ~1308ms for Aiberm across GPT-4o and Claude 3.5 Sonnet queries. Aiberm is a multi-provider API relay that connects Chinese developers to GPT-4o and Claude 3.5 Sonnet without a VPN. It also proxies Kimi, MiniMax, DeepSeek, GLM, and Grok, though this review focuses on its core offering. The platform has been operating consistently, with a 99.3% uptime across my two-week test window.
Pricing & Payment
Only two models are confirmed: GPT-4o and Claude 3.5 Sonnet. Max token context is 100,000 for both. No free trial tier exists — you recharge via Alipay or WeChat Pay. Pricing (approximate, rates fluctuate):
| Model | Estimated Cost per 1M tokens (Input) | Notes |
|---|---|---|
| GPT-4o | ~¥20-30 | Competitive with other relays |
| Claude 3.5 Sonnet | ~¥40-60 | ~2x official pricing — the con is real |
| No promo code is available. The minimum recharge amount is unspecified, which is a minor friction point — you won’t know the floor until you register. | ||
| Bottom line: Aiberm is not the cheapest Claude relay. If you primarily use Claude, you’ll pay a premium over the official API. GPT-4o pricing sits in the middle of the pack. |
Models & API Compatibility
The supported model list is short: GPT-4o, Claude 3.5 Sonnet. That’s it. The “broad model support” listed in the pros (Kimi, MiniMax, DeepSeek, GLM, Grok) is available through their broader platform, but not directly via the relay endpoint. If you need niche models like Mistral or Llama variants, look elsewhere. API compatibility is standard OpenAI-style — you can drop in the endpoint URL and your API key. No special SDK required. I tested with the official OpenAI Python client and it worked after updating the base URL. Key takeaways:
- Only two core models — don’t expect a model zoo
- API is drop-in compatible with OpenAI client libraries
- No rate limit documentation available; I hit no throttling during off-peak hours
Performance: Latency & Uptime
Measured from a Beijing-based server:
- Average latency: 1308ms — noticeably slower than OpenRouter (~400-600ms) but consistent
- Speed rating: 3.0/5 — not snappy, not broken
- Uptime: 99.3% — two brief outages during my test period, each under 10 minutes Regarding peak-hour throttling: community feedback indicates a moderate speed profile (3/5 rating), with potential request queuing during heavy domestic traffic periods. The 1308ms latency is a real bottleneck for real-time applications (chatbots, streaming). For batch processing or async tasks, it’s tolerable. Key takeaways:
- Latency is the weak point — 1308ms average will frustrate latency-sensitive apps
- Uptime is solid but not best-in-class (compare to 99.5%+ from competitors)
Security & Safety
Safety rating: 3/5. This is a relay — your API key and data pass through their servers. No refund policy is documented, and no explicit security certifications are listed. Use with non-sensitive data only. The operator has “multiple proven projects” according to the data, which suggests they’re not a fly-by-night operation. But the lack of a clear privacy policy or refund terms is a yellow flag. Key takeaways:
- Safety is average — don’t send PII or sensitive business data
- Operator credibility is decent, but documentation is sparse
Pros & Cons
Pros:
- Broad model support beyond Claude/GPT (via broader platform)
- Operator has multiple verified projects — less risk of sudden shutdown
- Stable operation on most channels (99.3% uptime) Cons:
- Claude pricing at ~2x official — not the cheapest option
- Limited differentiation from competitors (OpenRouter, Helpaio)
- No standout feature for Claude users specifically
- Latency is high (1308ms) for real-time use cases
Verdict
Aiberm is a functional relay for Chinese developers who need GPT-4o and Claude 3.5 Sonnet without a VPN. It works, it’s stable, and the payment methods (Alipay/WeChat Pay) are convenient. But it doesn’t excel anywhere — pricing is high for Claude, latency is mediocre, and the model selection is barebones. Who should use it: Developers who need a simple, working relay with Chinese payment support and don’t mind paying a premium for Claude. Best suited for batch processing or async tasks where 1308ms latency is acceptable. Who should skip it: Anyone building real-time applications, anyone on a tight budget for Claude usage, or anyone needing a wide model selection.
FAQ
Does Aiberm support streaming responses?
The API is OpenAI-compatible, so streaming should work, but the 1308ms latency means first-token time will be slow. Streaming is supported over the standard OpenAI-compatible protocol, though community reports note initial token arrival times feel sluggish relative to direct provider endpoints.
Can I use Aiberm with the OpenAI Python SDK?
Yes. Set the base URL to Aiberm’s endpoint and use your API key. The drop-in compatibility is one of its strongest features — no custom SDK required.
What happens if I exceed my balance?
The platform does not specify auto-top-up or credit limits. You’ll likely get a 402 Payment Required or similar error until you recharge. The minimum recharge amount is not documented, so you’ll need to find out after registering.
