<h1 align="center">ModelMux Roadmap</h1>

<p align="center">
<em>The future of AI proxy infrastructure ;-)</em><br/>
</p>

---

> *"I have never in my life learned anything from any man who agreed with me."* — Dudley Field Malone

---

## Vision

ModelMux - think of it as the nginx for AI models.

<!-- "The only way to get rid of temptation is to yield to it." - Oscar Wilde -->

---

## Current Status: v0.2.0

✅ **Production Ready**
- OpenAI to Vertex AI (Claude) proxy
- Streaming with intelligent client detection
- Tool/function calling support
- Rust Edition 2024 with type safety
- Comprehensive error handling
- CLI interface with `--version` and `--help` flags
- Comprehensive test suite (30+ tests)
- Homebrew deployment ready
- Professional packaging structure
- Dual MIT/Apache licensing

---

## Phase 1: Foundation

### Distribution & Packaging

**Homebrew Formula**
```bash
brew install modelmux
modelmux --version
```

**Docker Images**
```bash
docker run -p 3000:3000 yarenty/modelmux:latest
```

**Binary Releases**
- Linux (x86_64, ARM64)
- macOS (Intel, Apple Silicon)
- Windows (x86_64)

### DevOps & Tooling

**Configuration Validation**
```bash
modelmux validate config.yaml
modelmux doctor  # Health check for setup
```

**Enhanced Observability**
- Prometheus metrics export
- OpenTelemetry tracing
- Structured JSON logging
- Request/response debugging mode

> *"I refuse to belong to any club that would accept me as one of its members."* — Groucho Marx

### Monitoring Dashboard

**Web UI** (`/dashboard`)
- Real-time request metrics
- Provider health status
- Configuration management
- Request rate limiting controls

---

## Phase 2: Multi-Provider Universe

### Provider Ecosystem

**Core Providers**
- ✅ Vertex AI (Anthropic Claude) 
- 🔄 OpenAI (GPT-4, GPT-3.5)
- 🔄 Anthropic (Direct API)
- 🔄 Cohere (Command, Embed)
- 🔄 AWS Bedrock (Multiple models)
- 🔄 Azure OpenAI Service
- 🔄 Hugging Face Inference API

**Provider Configuration**
```yaml
providers:
  - name: openai
    type: openai
    api_key: ${OPENAI_API_KEY}
    models: ["gpt-4", "gpt-3.5-turbo"]
  
  - name: anthropic
    type: anthropic
    api_key: ${ANTHROPIC_API_KEY}
    models: ["claude-3-opus", "claude-3-sonnet"]

routing:
  strategy: cost_optimized
  fallback: true
```

### 🎯 Intelligent Routing

**Routing Strategies**
- `round_robin` - Equal distribution
- `latency` - Route to fastest provider
- `cost` - Route to cheapest model
- `availability` - Route around failures
- `model_specific` - Route by model capabilities
- `geographic` - Route by user location
- `custom` - Lua scripting for complex logic

<!-- "The trouble with quotes on the Internet is that you can never verify their authenticity." - Abraham Lincoln -->

**Advanced Features**
```yaml
routing:
  strategy: hybrid
  rules:
    - if: model == "gpt-4"
      provider: openai
    - if: cost_sensitive == true
      provider: cohere
    - if: latency < 100ms
      provider: local_llm
  
  fallback:
    enabled: true
    max_retries: 3
    backoff: exponential
```

---

## Phase 3: Performance & Scale

### ⚡ High-Performance Features

**Caching Layer**
```yaml
caching:
  enabled: true
  backend: redis
  ttl: 300s
  rules:
    - cache_if: deterministic == true
    - skip_if: stream == true
```

**Connection Pooling**
- HTTP/2 multiplexing
- Keep-alive optimization
- Circuit breaker patterns
- Rate limiting per provider

**Load Balancing**
- Weighted round-robin
- Least connections
- Geographic routing
- Health-based routing

### Hot Reloading

```bash
# Configuration changes without restart
modelmux reload config.yaml

# Zero-downtime updates
modelmux upgrade --version 0.2.0
```

> *"I am so clever that sometimes I don't understand a single word of what I am saying."* — Oscar Wilde

### Auto-Scaling

**Kubernetes Operator**
```yaml
apiVersion: modelmux.io/v1
kind: ModelMuxCluster
metadata:
  name: production
spec:
  replicas: 3
  providers:
    - openai
    - anthropic
  scaling:
    enabled: true
    minReplicas: 1
    maxReplicas: 10
```

---

## Phase 4: Enterprise Features

### Security & Compliance

**Authentication & Authorization**
- JWT token validation
- API key management
- Role-based access control
- Rate limiting per user/org

**Audit & Compliance**
- Request/response logging
- PII detection and redaction
- SOC 2 Type II compliance
- GDPR data handling

### Cost Management

**Usage Analytics**
```yaml
analytics:
  cost_tracking:
    enabled: true
    budgets:
      monthly: $1000
      alerts_at: 80%
  
  usage_reports:
    schedule: daily
    destinations: [email, webhook]
```

**Provider Cost Optimization**
- Real-time cost tracking
- Budget alerts and limits
- Cost prediction modeling
- Provider cost comparison

<!-- "The Internet is becoming the town square for the global village of tomorrow." - Confucius -->

### Global Deployment

**Multi-Region Support**
```yaml
regions:
  us-east-1:
    providers: [openai, anthropic]
  europe-west1:
    providers: [vertex_ai]
  asia-southeast1:
    providers: [bedrock]

routing:
  geographic: true
  data_residency: enforced
```

if prompt.contains_code() {
    route_to("claude-3-opus");
} else if prompt.is_creative() {
    route_to("gpt-4");
} else {
    route_to("cheapest_available");
}
```

### Advanced Multiplexing

**Request Aggregation**
- Batch multiple requests
- Parallel provider querying
- Response quality voting
- Consensus-based answers

**Model Composition**
```yaml
pipelines:
  - name: research_assistant
    steps:
      - provider: cohere
        task: summarize
      - provider: gpt-4
        task: analyze
      - provider: claude
        task: write_report
```

        // Custom implementation
    }
}
```
