TimiCC lists 2 models: GPT-4o and Claude 3.5 Sonnet. The platform is built for budget users who accept quirks in exchange for cheap access.

Model-by-Model Breakdown

GPT-4o

TimiCC offers GPT-4o through a GPT Team account at 0.05x the normal price — that’s ¥5 per ¥100 of usage. The platform claims 100.0% uptime and delivers 442ms latency, which is solid for a relay service. Stability is the concern. The platform’s 3/5 safety rating reflects the reverse-proxy nature. When OpenAI rate-limits or blocks relay IPs, GPT-4o goes down first. During the 2025-2026 period, users reported GPT-4o outages lasting 2-4 hours during peak China daytime hours. Context window hits 100,000 tokens. That’s the full GPT-4o 128K window, but TimiCC caps it at 100K. For most code generation and document analysis tasks, this is sufficient. Long-context retrieval tasks (100K+ tokens) will fail. Speed benchmarks: 4.5/5 rating. At 442ms average latency, it’s faster than most free relay services. The speed holds up under load because the user base is small. Bottom line: GPT-4o works for daily coding tasks but expect periodic outages. The 0.05x pricing makes it worthwhile if you can tolerate downtime.

Claude 3.5 Sonnet

Claude 3.5 Sonnet runs through a cheap reverse-proxy at ¥1 input / ¥5 output per million tokens. This is approximately 0.1x the official API pricing. The same 100.0% uptime applies, but Claude models face different failure modes. Anthropic’s API has stricter abuse detection. When the proxy IP gets flagged, Claude Sonnet goes offline for 6-12 hours — longer than GPT-4o outages. Latency for Claude is also ~442ms, but first-token latency spikes to 800ms-1.2s during Chinese evening hours (8-11 PM CST). The speed rating of 4.5/5 is averaged across all hours. Context window: 100,000 tokens. Claude 3.5 Sonnet natively supports 200K, so you lose half the context. This matters for codebase analysis or long document summarization. Bottom line: Claude 3.5 Sonnet is cheap but unreliable. Use it for short prompts and quick code reviews, not production workloads.

Pros & Cons

Pros

  • GPT Team accounts at 0.05x — nearly free for GPT-4o
  • ¥1 free credit on registration, no upfront cost
  • 100.0% uptime claimed, 4.5/5 speed rating
  • Alipay and WeChat Pay accepted Cons
  • QQ email registration only — privacy concern, no Gmail/Outlook
  • Claude reverse-proxy unreliable during peak hours
  • 100K context cap loses half of Claude’s native 200K window
  • No refund policy, no SLA guarantees
  • Retired Codex subscription (¥100/day ¥60) with no replacement

Verdict

TimiCC is for developers who want cheap access to GPT-4o and Claude 3.5 Sonnet without a VPN, and are willing to accept outages and quirks. The ¥1 free credit lets you test before committing. The 100.0% uptime claim is misleading — individual models go down, even if the platform stays up. For GPT-4o at 0.05x, it’s worth the ¥1 test. For Claude 3.5 Sonnet, the reverse-proxy unreliability makes it a backup option at best. If you need production-grade reliability, look elsewhere.

FAQ

Is TimiCC safe to use with my API keys?

No. TimiCC is a reverse-proxy service. Your prompts pass through their servers. The 3/5 safety rating reflects this. Do not send sensitive data.

Why does Claude 3.5 Sonnet go down more often than GPT-4o?

Anthropic has stricter abuse detection than OpenAI. When the relay IP gets flagged, Claude models get blocked for 6-12 hours. GPT-4o outages are shorter (2-4 hours) because OpenAI’s detection is less aggressive on relay traffic.

Can I use TimiCC with my own OpenAI or Anthropic API key?

No. TimiCC provides shared Team accounts and reverse-proxy access. You cannot bring your own API key. All usage goes through their pooled accounts.

What happens if I hit the 100,000 token limit?

Requests exceeding 100K tokens will fail. For GPT-4o, this is close to the native 128K limit. For Claude 3.5 Sonnet, you lose half the native 200K window. Plan your prompts accordingly.

Does TimiCC work without a VPN in China?

Yes. That’s the entire point. TimiCC routes traffic through domestic servers. No VPN required. The ¥1 free credit lets you verify connectivity before paying.
