Back openDesk Edu for a sovereign, open-source education — every vote counts.
Vote nowChallenge: The architecture lacks centralized LLM integration, creating fragmented API access, inconsistent observability, and uncontrolled costs.
Solution: LiteLLM unified proxy server to standardize 100+ LLM providers (OpenAI, Claude, Mistral, local models) into a single OpenAI-compatible interface.
Results Delivered:
The modern LLM landscape demands integration with:
Each provider requires:
This creates:
| Requirement | Current Status | LiteLLM Solution |
|---|---|---|
| Centralized API Access | ❌ None | ✅ Unified OpenAI-Compatible |
| Cost Transparency | ❌ None | ✅ Real-time Dashboard |
| Reliability | ❌ Single Point | ✅ Automatic Failovers |
| Provider Switching | ❌ Manual Code | ✅ Config-Driven Routing |
| Governance Framework | ❌ None | ✅ Usage Policies |
LiteLLM acts as a translation layer that:

## Implementation Blueprint
### 1. Proxy Deployment
**Docker Setup:**
```bash
# docker-compose.yml
services:
litellm-proxy:
image: ghcr.io/berriai/litellm:main-latest
ports:
- "4000:4000"
- "4001:4001"
volumes:
- ./config.yaml:/app/config.yaml
environment:
- DATABASE_URL=postgresql://...
- REDIS_CACHE=redis://...
```text
### 2. GraphWiz Integration
**Unified Client:**
```javascript
const client = new OpenAI({
baseURL: "https://api.example.com/proxy",
apiKey: "sk-1234"
});
// Works with any configured model
const completion = await client.chat.completions.create({
model: "gpt-4o",
messages: [{role: "user", content: "Hello!"}]
});
```text
**Smart Routing Configuration:**
```yaml
model_list:
# Primary: Azure OpenAI
- model_name: gpt-4o
litellm_params:
model: azure/graphwiz-east
order: 1
rpm: 10000
# Fallback: Anthropic
- model_name: gpt-4o
litellm_params:
model: anthropic/claude-3.5-sonnet
order: 2
rpm: 5000
# Cost-Optimized: Local vLLM
- model_name: mistral-local
litellm_params:
model: vllm/mistral-ins-7b
order: 3
```text
## Advanced Configuration
**Per-Team Budgets:**
```yaml
teams:
engineering:
budget: $200/day
allowed_models: ["gpt-4o", "claude-3.5"]
research:
budget: $1000/day
allowed_models: ["gpt-4o", "*"]
```text
**Cost Optimization:**
```yaml
litellm_settings:
enable_caching: true
cache_params:
type: redis
ttl: 3600 # 1 hour cache
cost_thresholds:
daily_alert: $900
hard_limit: $1000
```text
## Production Deployment
**Single-Region Architecture:**

B --> D[Redis \(Caching\)]
B --> E[OpenAI/Azure]
B --> F[Anthropic]
B --> G[vLLM Local]
```text
**Multi-Region Strategy:**
```yaml
# config-multi-region.yaml
model_list:
# East deployment
- model_name: gpt-4o
litellm_params:
model: azure/graphwiz-east
region: us-east
weight: 0.7
# West deployment
- model_name: gpt-4o
litellm_params:
model: azure/graphwiz-west
region: eu-west
weight: 0.3
```text
## Monitoring & Observability
**Prometheus Metrics:**
```bash
litellm_requests_total{model,team}
litellm_cost_accumulated{team,model}
litellm_fallback_occurred{source,target}
litellm_latency_bucket{le=0.1,le=0.5,le=1,le=2}
```text
**Response Headers:**
```http

x-litellm-model-used: azure/gpt-4o
x-litellm-cache-hit: false

## Future-Proofing
**Emerging Models Template:**
```yaml
# future-models.yaml
model_list:
- model_name: google/gemini-pro
litellm_params:
model: vertex_ai/gemini-pro
vertex_project: graphwiz-sovereign
- model_name: custom/private-model
litellm_params:
model: openai/custom-endpoint
base_url: http://private-ai:8000/v1
