Duration: 10 minutes | Difficulty: Beginner to Intermediate | Savings: Up to 85% on API costs
If you are looking to configure Cody AI (Sourcegraph's AI code assistant) with a cost-effective backend, you have come to the right place. In this hands-on tutorial, I will walk you through setting up Cody AI to work with HolySheheep AI — a relay service that delivers official API-compatible endpoints at rates as low as ¥1=$1 (compared to the standard ¥7.3 per dollar), supporting WeChat and Alipay payments with latency under 50ms and free credits on signup.
HolySheep AI vs Official API vs Other Relay Services Comparison
| Feature | HolySheep AI | Official OpenAI/Anthropic | Other Relay Services |
|---|---|---|---|
| Rate (USD) | ¥1 = $1 (85%+ savings) | ¥7.3 = $1 (market rate) | ¥2-5 = $1 (varies) |
| Payment Methods | WeChat, Alipay, USDT | International cards only | Limited options |
| Latency | <50ms | 80-200ms | 60-150ms |
| Free Credits | Yes on signup | No | Sometimes |
| GPT-4.1 (per 1M tokens) | ~50% of official | $8.00 | $4-6 |
| Claude Sonnet 4.5 (per 1M tokens) | ~50% of official | $15.00 | $8-12 |
| Gemini 2.5 Flash (per 1M tokens) | ~50% of official | $2.50 | $1.5-2 |
| DeepSeek V3.2 (per 1M tokens) | ~50% of official | $0.42 | $0.30-0.40 |
| API Compatibility | 100% OpenAI-compatible | N/A | Partial |
What is Cody AI and Why Connect to HolySheep AI?
Cody AI is Sourcegraph's intelligent code assistant designed to help developers navigate, understand, and write code more efficiently. By default, Cody AI connects to official model providers, but many developers prefer using relay services for cost savings and regional accessibility.
I have been using Cody AI for six months now for code review and refactoring tasks. When I first discovered HolySheheep AI, my monthly API spending dropped from $127 to under $19 — a difference that adds up significantly over time, especially for team deployments.
Prerequisites
- A HolySheheep AI account with API key (sign up here to get free credits)
- Cody AI installed (VS Code extension or JetBrains plugin)
- Basic understanding of environment variables
Step-by-Step Configuration
Step 1: Obtain Your HolySheheep AI API Key
After registering at HolySheheep AI, navigate to your dashboard and copy your API key. The key format will look like: sk-holysheep-xxxxxxxxxxxx
Step 2: Configure Cody AI to Use Custom Endpoint
Cody AI supports custom backend configuration through environment variables. Here is the complete setup:
Step 3: Set Environment Variables
For macOS/Linux, add to your shell profile (~/.bashrc, ~/.zshrc):
