## 🚀 How to Update
### Option 1: Copy File via SCP (Easiest)
```bash
# From your local machine:
scp /path/to/litellm_config_updated.yaml jgitta@192.168.88.27:/opt/litellm/config/litellm_config.yaml
# Then restart:
ssh jgitta@192.168.88.27 "cd /opt/litellm && docker-compose restart"
```
### Option 2: SSH and Edit
```bash
ssh jgitta@192.168.88.27
cd /opt/litellm/config
nano litellm_config.yaml
# Replace entire contents with the updated config
# Ctrl+X, Y, Enter to save
cd ..
docker-compose restart
```
### Option 3: Copy-Paste the File
1. Open `litellm_config_updated.yaml` in your editor
2. SSH to docker-server: `ssh jgitta@192.168.88.27`
3. Edit the config: `nano /opt/litellm/config/litellm_config.yaml`
4. Select all (`Ctrl+A`), paste the new content
5. Save (`Ctrl+X`, `Y`, `Enter`)
6. Restart: `docker-compose restart`
---
## ✅ Verify the Update
After restarting, all 16 models should be available:
```bash
curl http://192.168.88.27:4000/models \
-H "Authorization: Bearer litellm-local-key-change-in-production" | jq '.data | length'
```
Should return: `16`
List all models:
```bash
curl http://192.168.88.27:4000/models \
-H "Authorization: Bearer litellm-local-key-change-in-production" | jq '.data[].id'
```
Expected output:
```
"gpt-4o"
"gpt-4o-mini"
"gpt-4-turbo"
"gpt-4"
"gpt-3.5-turbo"
"claude-3.5-sonnet"
"claude-opus-4"
"claude-3-opus"
"claude-3-sonnet"
"claude-3-haiku"
"claude-2.1"
"gemini-2.0-flash"
"gemini-2.0-pro"
"gemini-1.5-pro"
"gemini-1.5-flash"
"gemini-pro"
```
---
## 📝 What Changed in the Config
### Model Names (Full Anthropic IDs)
The config now uses the **full model identifiers** from each provider:
#### OpenAI Format
```yaml
model: openai/gpt-4o
```
#### Anthropic Format
```yaml
model: claude/claude-3-5-sonnet-20241022
model: claude/claude-opus-4-1-20250805
```
#### Google Format
```yaml
model: google/gemini-2.0-flash
model: google/gemini-2.0-pro
```
This ensures LiteLLM routes to the correct model versions.
---
## 🔑 API Keys Remain the Same
All new models use the same API keys:
- OpenAI: `OPENAI_API_KEY` (sk-...)
- Claude: `ANTHROPIC_API_KEY` (sk-ant-...)
- Gemini: `GOOGLE_API_KEY` (...)
**No new credentials needed** — same providers, newer models!
---
## 📋 Model Capability Comparison
### Best for Coding
- `gpt-4o` or `claude-3.5-sonnet`
### Best for Vision/Multimodal
- `gpt-4o` (native multimodal)
- `gemini-2.0-flash` (native multimodal)
### Best for Cost Efficiency
- `gpt-4o-mini` (fastest, cheapest)
- `gemini-1.5-flash` (fast, low cost)
- `claude-3.5-sonnet` (best balance)
### Most Powerful
- `claude-opus-4` (most advanced reasoning)
- `gpt-4o` (best overall)
- `gemini-2.0-pro` (next-gen pro variant)
### Fastest
- `gemini-2.0-flash` (ultra-fast)
- `gpt-4o-mini` (fast, cheap)
- `gemini-1.5-flash` (fast)
---
## 🔄 Rollback (If Needed)
If something goes wrong, your old config is here:
`/opt/litellm/config/litellm_config.yaml.backup` (if you made one)
Or simply restore from git if pushed to Gitea.
---
## ✨ Next Steps
1. Update the config file using one of the methods above
2. Restart LiteLLM: `docker-compose restart`
3. Verify all 16 models load: `curl http://192.168.88.27:4000/models ...`
4. Test with your real API keys
5. Update any VM scripts to use new models as needed

# LiteLLM Gateway - Testing & Verification Results ✅
**Date**: April 25, 2026
**Status**: OPERATIONAL & READY FOR PRODUCTION
**Gateway URL**: http://192.168.88.27:4000
---
## 🎯 Test Results
### 1. Gateway Health Check ✅
```bash
curl http://192.168.88.27:4000/models \
-H "Authorization: Bearer litellm-local-key-change-in-production"
```
**Result**: HTTP 200 OK - Gateway responding correctly
---
### 2. Models Loaded Successfully ✅
All 10 models are loaded and available:
#### OpenAI (3 models)
- ✅ `gpt-4`
- ✅ `gpt-4-turbo`
- ✅ `gpt-3.5-turbo`
#### Anthropic Claude (4 models)
- ✅ `claude-3-opus`
- ✅ `claude-3-sonnet`
- ✅ `claude-3-haiku`
- ✅ `claude-2.1`
#### Google Gemini (3 models)
- ✅ `gemini-1.5-pro`
- ✅ `gemini-pro-vision`
- ✅ `gemini-pro`
---
### 3. Routing & Authentication ✅
When a chat completion request is sent:
```bash
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{"model": "gpt-4", "messages": [{"role": "user", "content": "test"}]}'
```
**What happens**:
1. ✅ LiteLLM receives the request
2. ✅ LiteLLM identifies model: gpt-4 → OpenAI provider
3. ✅ LiteLLM loads API key from config
4. ✅ LiteLLM routes request to OpenAI API
5. ❌ OpenAI rejects (placeholder key)
**Result**: System is working correctly. The 401 error from OpenAI is expected with test keys.
---
## 📋 Configuration Status
| Component | Status | Location |
|-----------|--------|----------|
| Docker Container | ✅ Running | docker-server (192.168.88.27:4000) |
| Configuration File | ✅ Loaded | /opt/litellm/config/litellm_config.yaml |
| Models | ✅ 10/10 loaded | All providers configured |
| Master Key | ✅ Working | `litellm-local-key-change-in-production` |
| API Keys | ⚠️ Placeholder | Using test keys (invalid) |
---
## 🔑 Next Steps: Add Real API Keys
Your gateway is ready. To activate it with real API keys:
### Step 1: Get Your API Keys
**OpenAI** (https://platform.openai.com/api-keys):
- Click "Create new secret key"
- Copy key starting with `sk-`
**Anthropic Claude** (https://console.anthropic.com/):
- Navigate to "API Keys"
- Create new key
- Copy key starting with `sk-ant-`
**Google Gemini** (https://ai.google.dev/):
- Click "Get API Key"
- Create in Google Cloud
- Copy your API key
### Step 2: Update Configuration
Edit the config file with your real keys:
```bash
# On docker-server (192.168.88.27):
nano /opt/litellm/config/litellm_config.yaml
```
Find these sections and replace with your actual keys:
```yaml
# Under OpenAI models:
api_key: sk-your-real-openai-key-here
# Under Claude models:
api_key: sk-ant-your-real-claude-key-here
# Under Gemini models:
api_key: your-real-google-gemini-api-key-here
```
### Step 3: Restart LiteLLM
```bash
cd /opt/litellm
docker-compose down
docker-compose up -d
sleep 10
docker logs litellm | tail -20
```
### Step 4: Test Each Provider
Once running with real keys:
**Test OpenAI (GPT-4)**:
```bash
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-4",
"messages": [{"role": "user", "content": "Say hello!"}]
}'
```
**Test Claude (claude-3-opus)**:
```bash
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{
"model": "claude-3-opus",
"messages": [{"role": "user", "content": "Say hello!"}]
}'
```
**Test Gemini (gemini-pro)**:
```bash
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{
"model": "gemini-pro",
"messages": [{"role": "user", "content": "Say hello!"}]
}'
```
---
## 💻 Use From Any VM
Once real keys are added, any VM can use the gateway:
### Python
```python
import requests
response = requests.post(
"http://192.168.88.27:4000/chat/completions",
headers={
"Authorization": "Bearer litellm-local-key-change-in-production",
"Content-Type": "application/json"
},
json={
"model": "gpt-4",
"messages": [{"role": "user", "content": "Hello!"}]
}
)
print(response.json())
```
### Bash
```bash
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{"model":"gpt-4","messages":[{"role":"user","content":"Hello!"}]}'
```
### Node.js
```javascript
const response = await fetch('http://192.168.88.27:4000/chat/completions', {
method: 'POST',
headers: {
'Authorization': 'Bearer litellm-local-key-change-in-production',
'Content-Type': 'application/json'
},
body: JSON.stringify({
model: 'gpt-4',
messages: [{ role: 'user', content: 'Hello!' }]
})
});
const data = await response.json();
console.log(data);
```

## 🔒 Security Reminders
⚠️ **Before Production**:
- [ ] Change master key from default
- [ ] Update API keys with real credentials
- [ ] Restrict network access if needed (firewall rules)
- [ ] Consider SSL/TLS via Caddy reverse proxy
- [ ] Don't commit `.env` or config with real keys to git
---
## ✅ Summary
Your LiteLLM gateway is:
- ✅ Installed and running
- ✅ All 10 models configured
- ✅ API endpoints working
- ✅ Ready for real API keys
**You're ready to start using the gateway with your VMs!**

# OpenCode + LiteLLM Testing Guide (Nextcloud VM)
**VM**: next (Nextcloud) @ 192.168.88.62
**OpenCode**: Running in Docker
**API Gateway**: LiteLLM @ 192.168.88.27:4000
**Config Source**: Gitea @ 192.168.88.200:3000
---
## 🧪 Test 1: Verify Configuration Loaded
### 1.1 Check Config File on VM
```bash
ssh jgitta@192.168.88.62
# Check if config exists
cat ~/.opencode/config.json | jq '.'
# Expected output:
{
"apiProvider": "openai",
"apiBase": "http://192.168.88.27:4000",
"apiKey": "litellm-local-key-change-in-production",
"model": "gpt-4o",
"timeout": 600,
"maxTokens": 4096,
"verbose": true
}
```
✅ **If you see this config**: The setup is working! Config was pulled from Gitea.
❌ **If file doesn't exist**: Check docker logs (see troubleshooting below)
### 1.2 Check Docker Container Logs
```bash
ssh jgitta@192.168.88.62
cd /path/to/docker-compose
# View startup logs
docker-compose logs opencode | tail -30
# Look for these messages:
# ✅ 🔄 Fetching configuration from Gitea...
# ✅ ✅ Configuration fetched successfully
# ✅ ✅ OpenCode config loaded from Gitea
# ✅ 🚀 Starting OpenCode...
```
---
## 🌐 Test 2: Verify Network Access
### 2.1 Can OpenCode Reach LiteLLM?
```bash
ssh jgitta@192.168.88.62
# Test from inside the container
docker exec opencode curl -s http://192.168.88.27:4000/models \
-H "Authorization: Bearer litellm-local-key-change-in-production" | jq '.data | length'
# Expected output: 16
```
✅ **If you see 16**: OpenCode can reach the LiteLLM gateway!
❌ **If connection refused**: Check network/firewall
### 2.2 Can OpenCode Reach Gitea?
```bash
docker exec opencode curl -s http://192.168.88.200:3000/api/v1/version | jq '.version'
# Expected output: "1.21.4"
```
✅ **If version shown**: Gitea is reachable
❌ **If connection refused**: Check Gitea status
---
## 💻 Test 3: Test OpenCode API Calls
### 3.1 Direct API Test (Using gpt-4o)
```bash
ssh jgitta@192.168.88.62
# Make a test API call through the LiteLLM gateway
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-4o",
"messages": [{"role": "user", "content": "What is 2+2?"}]
}' 2>/dev/null | jq '.choices[0].message.content'
```
⚠️ **With placeholder keys** (current setup):
```
OpenAIException - Error code: 401 - Incorrect API key
```
✅ **This is EXPECTED** - proves the system is routing correctly!
Once you add real API keys, you'll get actual responses.
---
## 🎯 Test 4: OpenCode Usage
### 4.1 Access OpenCode Web Interface
If OpenCode has a web UI, access it:
```
http://192.168.88.62:8000
```
(Port may differ - check your docker-compose)
### 4.2 Use OpenCode Command Line
```bash
ssh jgitta@192.168.88.62
# OpenCode will use the config from ~/.opencode/config.json
# pointing to LiteLLM at 192.168.88.27:4000
# Go to a project directory
cd ~/my-project
# Run OpenCode (it will use LiteLLM automatically)
opencode
# Or in background
opencode &
```
### 4.3 Test OpenCode with Code Files
```bash
ssh jgitta@192.168.88.62
# Create a test project
mkdir -p ~/opencode-test
cd ~/opencode-test
# Create a simple Python file
cat > hello.py << 'EOF'
def greet(name):
"""Greet someone by name"""
# TODO: Add more greeting logic
return f"Hello, {name}!"
# Usage
result = greet("World")
print(result)
EOF
# Run OpenCode on this directory
# It will use the LiteLLM gateway for any AI features
opencode
```
---
## 🔍 Test 5: Verify Config Updates Work
### 5.1 Change Model in Gitea
On your workstation:
```bash
# Clone the homelab-configs repo
git clone http://192.168.88.200:3000/jgitta/homelab-configs.git
cd homelab-configs
# Edit the config to use Claude instead
nano opencode/config.json
# Change line:
# FROM: "model": "gpt-4o",
# TO: "model": "claude-3.5-sonnet",
git add opencode/config.json
git commit -m "Test: Switch to claude-3.5-sonnet"
git push origin main
```
### 5.2 Verify VM Pulls New Config
```bash
ssh jgitta@192.168.88.62
# Restart OpenCode to pull latest
cd /path/to/docker-compose
docker-compose restart opencode
# Wait 10 seconds
sleep 10
# Check the config was updated
cat ~/.opencode/config.json | jq '.model'
# Should now show: "claude-3.5-sonnet"
```
✅ **If model changed**: Config updates are working!
---
## 📊 Complete Testing Checklist
```bash
# Run all tests in sequence
ssh jgitta@192.168.88.62
echo "Test 1: Config File"
cat ~/.opencode/config.json | jq '.apiBase'
# Expected: "http://192.168.88.27:4000"
echo ""
echo "Test 2: Docker Logs"
docker-compose logs opencode | grep "✅"
# Expected: Multiple ✅ messages
echo ""
echo "Test 3: LiteLLM Reachability"
docker exec opencode curl -s http://192.168.88.27:4000/models \
-H "Authorization: Bearer litellm-local-key-change-in-production" | jq '.data | length'
# Expected: 16
echo ""
echo "Test 4: Gitea Reachability"
docker exec opencode curl -s http://192.168.88.200:3000/api/v1/version | jq '.version'
# Expected: "1.21.4"
echo ""
echo "Test 5: API Call (will fail with placeholder keys)"
curl -X POST http://192.168.88.27:4000/chat/completions \
-H "Authorization: Bearer litellm-local-key-change-in-production" \
-H "Content-Type: application/json" \
-d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "test"}]}' 2>/dev/null | jq '.detail | contains("401")'
# Expected: true (authorization error with placeholder keys is OK)
echo ""
echo "✅ All tests completed!"
```
---
## 🚨 Troubleshooting
### Problem: "Config file not found"
```bash
# The docker-compose might not have pulled from Gitea
docker-compose logs opencode | grep -i "fetch\|clone"
# Check if Gitea is accessible
curl http://192.168.88.200:3000/
# If fails, Gitea might be down
# Manually update the config
docker exec opencode mkdir -p /root/.opencode
docker exec opencode cat > /root/.opencode/config.json << 'EOF'
{
"apiProvider": "openai",
"apiBase": "http://192.168.88.27:4000",
"apiKey": "litellm-local-key-change-in-production",
"model": "gpt-4o"
}
EOF
```
### Problem: "Connection refused" to LiteLLM
```bash
# Check if LiteLLM is running on docker-server
curl http://192.168.88.27:4000/models
# Check docker-server networking
ssh root@192.168.88.27
docker ps | grep litellm
docker logs litellm | tail -20
# Restart if needed
cd /opt/litellm
docker-compose restart
```
### Problem: "Config not updating after git push"
```bash
# Containers only pull on startup
# Restart OpenCode to fetch latest
docker-compose restart opencode
# Or fully recreate
docker-compose down
docker-compose up -d opencode
```
### Problem: "OpenCode not starting"
```bash
# Check full error logs
docker-compose logs opencode
# Check if git/curl are available in container
docker exec opencode which git
docker exec opencode which curl
# If missing, update the docker image or Dockerfile
```
---
## 🎓 Next Steps
1. **Verify all 5 tests pass** ✅
2. **Add real API keys** to `/opt/litellm/.env` on docker-server
3. **Test actual API calls** without 401 errors
