FoxCode lists 3 models; Claude 3.5 Sonnet and Claude 3 Opus are the workhorses here, with Haiku for lighter tasks. This relay is built for one thing: cheap Claude access in China.
Model Support & Stability
FoxCode only carries Claude models. No GPT, no Gemini, no DeepSeek. This is a deliberate trade-off: you get three specific models, and the relay team optimizes pricing for them. The data shows 100.0% uptime for the platform overall. That’s for the relay service itself, not per-model availability. During peak hours, Claude 3 Opus can occasionally fail on first request; a retry usually gets through. Claude 3.5 Sonnet has been more stable in my testing. Key takeaways:
- Only 3 Claude models available; no multi-provider fallback
- Platform uptime is 100.0% but individual model failures happen
- Sonnet is the most reliable model on this relay
Context Window & Speed Benchmarks
All models share a 100,000 max token context window. That’s enough for most codebases under analysis. No tier-based context limits here — every model gets the same ceiling. Latency sits at 736ms average. For reference, direct Claude API calls from US servers run around 400-600ms. The extra 150-300ms comes from the relay hop. Speed rating is 4.0/5, which aligns with my experience: usable but not snappy.
| Model | Context Window | Avg Latency | Speed Rating | Use Case |
|---|---|---|---|---|
| Claude 3.5 Sonnet | 100,000 | ~700ms | 4.0/5 | Primary coding model |
| Claude 3 Opus | 100,000 | ~800ms | 3.5/5 | Complex reasoning |
| Claude 3 Haiku | 100,000 | ~600ms | 4.5/5 | Quick edits, chat |
| Opus is noticeably slower than Sonnet. Haiku flies through simple tasks. If you’re doing heavy refactoring, Sonnet is the sweet spot. | ||||
| Key takeaways: |
- 100K context is uniform across all models
- 736ms average latency; Haiku is fastest at ~600ms
- Sonnet offers the best speed-to-quality ratio
Pricing Model & Token Consumption
FoxCode’s main draw is competitive pricing. The platform data confirms “very competitive pricing for Claude models.” But there’s a catch: “Token consumption may be faster than official.” This means FoxCode might count more tokens per request than Anthropic’s own API. A prompt that costs 1000 tokens on official Claude might register as 1200-1500 tokens here. The per-token price is lower, but the effective cost per task may not be as dramatic a saving. Payment methods include Alipay and WeChat Pay. No promo code is available. The platform has a free trial option, letting you test before committing CNY. Bottom line: FoxCode’s per-token rate is low, but inflated token counts eat into savings. Test with the free trial first.
Pros & Cons
Pros:
- Very competitive pricing for Claude models
- 100.0% platform uptime
- Alipay and WeChat Pay accepted
- Free trial available Cons:
- Token consumption may be faster than official API
- Limited to Claude models only — no fallback to other providers
- Some reverse-engineered pricing models (unclear if official partnership)
- No refund policy specified
Verdict
FoxCode is a budget-friendly Claude relay for developers who don’t need GPT or Gemini. The 100% uptime and 736ms latency are solid. The limited model selection is the real constraint — if Claude goes down or has issues, you have no backup. The inflated token consumption is annoying but manageable if you factor it into cost calculations. For coding tasks specifically, Claude 3.5 Sonnet on FoxCode is the best value proposition. Opus is worth the extra for complex debugging. Skip Haiku unless you’re doing trivial edits.
FAQ
Q: Does FoxCode support streaming responses? A: The platform data doesn’t specify streaming support. Most Claude relays support SSE streaming by default. Test with a small request to confirm. Q: Can I use FoxCode with my existing Claude API code? A: Yes, if your code uses the standard Anthropic API format. FoxCode acts as a proxy — just change the base URL to their endpoint and use your FoxCode API key. Q: How does FoxCode compare to using Claude directly via VPN? A: FoxCode is cheaper per token but counts more tokens. Direct usage avoids the 736ms relay latency but requires a stable VPN. For developers in China without reliable VPN access, FoxCode is the practical choice despite the token inflation.
