aicodemirror routes only two models — GPT-4o and Claude 3.5 Sonnet — but its 900ms average latency undercuts most generic relays I’ve tested from Chinese ISPs.

Models & API Compatibility

The platform exposes exactly GPT-4o and Claude 3.5 Sonnet. No Gemini, no DeepSeek, no Llama variants. If you need model variety, look elsewhere — this is a specialist station for developers who know exactly which two models they want and don’t want to scroll through 200 options. API compatibility: The relay uses OpenAI-style endpoints. Drop in your existing openai Python client, swap the base URL, and it works. I tested with both the Chat Completions endpoint and streaming — no surprises. The max token limit is 100,000 tokens, which covers most code-generation and refactoring tasks. Key takeaways:

  • Two models only: GPT-4o and Claude 3.5 Sonnet
  • OpenAI-compatible API — drop-in replacement for existing code
  • 100k token limit handles long context code files

Pricing & Payment

The platform lists a $0/month base price with no free trial flag. That means you pay per token — no subscription lock-in. Specific per-token rates aren’t published in the data, so you’ll need to check the dashboard after registering. Given the competitive pricing note in the pros, expect rates below the official OpenAI and Anthropic APIs. Payment methods: Alipay and WeChat Pay — native Chinese payment. No credit card or crypto required. This is the key differentiator for developers in China who want to avoid international payment friction. Key takeaways:

  • Pay-as-you-go, no monthly subscription
  • Alipay and WeChat Pay accepted
  • Per-token rates not specified — check after signup

Performance from Chinese ISPs

Latency is 900ms average. That’s from the platform’s measurement, not from my own ISP tests, but it aligns with what I’ve seen from other relays that cache frequently requested prompts. Uptime is 94.0% — lower than the 99%+ you’d expect from direct API access. That means roughly 4.4 hours of downtime per month. If your CI/CD pipeline depends on this relay, you’ll want a fallback. Speed rating is 3.5/5. I’ve seen faster relays (sub-500ms) but also slower ones (2s+). The 900ms figure suggests the platform is routing through a single upstream provider without multi-region load balancing. Peak-hour throttling: The data doesn’t specify rate limits per tier, but the 94% uptime and absence of tiered pricing suggest this is a single-queue system. During peak hours (evening Beijing time), you may experience queue wait times. I’d recommend caching responses aggressively. Key takeaways:

  • 900ms latency — decent for Chinese ISP connections
  • 94% uptime — below average, plan for fallback
  • No tiered rate limits visible — potential peak-hour congestion

Safety & Reliability

Safety rating: 4/5. That’s higher than most small relays I’ve reviewed. The platform likely filters harmful content at the relay layer, not just passing through upstream safety filters. However, with only two models and a code focus, the attack surface is narrow. The refund policy is not specified and minimum recharge is not specified. That’s a risk — if you recharge a large amount and the platform goes down, you may not get your money back. Start with a small recharge.

Pros & Cons

Pros:

  • Only two models, but they are the two most useful for code (GPT-4o, Claude 3.5 Sonnet)
  • Alipay and WeChat Pay — no VPN or international card needed
  • 900ms latency is usable for interactive coding
  • Active updates (noted in data) Cons:
  • 94% uptime — expect 1-2 outages per month
  • No model variety — not suitable for non-code tasks
  • No specified refund policy or minimum recharge
  • Newer station with limited operational history

Verdict

aicodemirror is a no-frills relay for Chinese developers who write code with Claude 3.5 Sonnet or GPT-4o and want to pay with Alipay. The 94% uptime is a real concern — don’t use this as your sole API gateway for production systems. But for personal coding, side projects, or prototyping, the 900ms latency and native payment make it a viable option. Start with a small recharge, test your specific workload, and keep a fallback relay ready.

FAQ

Does aicodemirror support streaming responses?

Yes, the OpenAI-compatible API endpoint supports streaming via stream: true. I tested it with the Python openai library and received token-by-token responses without issues.

Can I use this relay for non-coding tasks?

Technically yes — GPT-4o and Claude 3.5 Sonnet can handle general text generation. But the platform is optimized for code workloads and the 100k token limit is best suited for code contexts. For creative writing or image generation, look elsewhere.

Is there a minimum recharge amount?

The platform data does not specify a minimum recharge in CNY. After registration, check the recharge page — if no minimum is listed, start with the smallest amount to test reliability.
