## Content

Your company uses six different AI providers. OpenAI for ChatGPT, Anthropic for Claude and Groq for speed critical inference.

Each one has different API formats. Different authentication models. Different rate limits and costs. Different failure modes.

Your application code has to know about all of them. Your security team has to audit requests across all of them. Your finance team has to track costs across all of them. Your compliance team has to ensure governance across all of them.

Bifrost Gateway solves this by doing what HTTP gateways have done for decades: **centralizing control**. But for AI.

## 🔎 The Bifrost Gateway

At its core, Bifrost LLM gateway is remarkably simple: a unified API endpoint that sits between your applications and all your AI providers.

Instead of:

// Traditional: Point directly at each provider

const response = await [openai.chat](http://openai.chat).completions.create({...});

You do:

// With Bifrost: Route through your gateway

const response = await fetch('[https://bifrost.yourcompany.com/v1/chat/completions](https://bifrost.yourcompany.com/v1/chat/completions)', {

headers: { 'x-bf-vk': 'vk-prod-main' },

body: JSON.stringify({model: 'gpt-4o', messages: [...]})

});

That's it. One endpoint. Everything else flows through the gateway.

But now you've connected something magical: **your entire AI infrastructure becomes visible and controllable**.

### Unified API Across 23+ Providers and 1000+ models

This is where Bifrost's real power emerges. You configure multiple providers once in the gateway:

```
{
  "providers": [
    {
      "name": "openai",
      "api_key": "sk-...",
      "models": ["gpt-4o", "gpt-4o-mini", "o1"]
    },
    {
      "name": "anthropic",
      "api_key": "sk-ant-...",
      "models": ["claude-3-sonnet", "claude-3-opus"]
    }
  ]
}
```

Now your applications can request models by name, and Bifrost handles routing them to the right provider:

```
// Request GPT-4o → routes to OpenAI
// Request Claude-3-Sonnet → routes to Anthropic
// All through the same /v1/chat/completions endpoint
```

## ⚙️ Gateway Capabilities

### 1. Intelligent Routing & Failover

Bifrost doesn't just route requests, it implements **resilient routing** out of the box.

#### Weighted Load Balancing

You can distribute traffic across providers based on cost, performance, or capacity:

```
{
  "virtual_key": "vk-prod-main",
  "provider_configs": [
    {
      "provider": "openai",
      "allowed_models": ["gpt-4o", "gpt-4o-mini"],
      "weight": 0.5  // 50% of traffic
    },
    {
      "provider": "anthropic",
      "allowed_models": ["claude-3-sonnet"],
      "weight": 0.3  // 30% of traffic
    },
    {
      "provider": "groq",
      "allowed_models": ["mixtral"],
      "weight": 0.2  // 20% of traffic (for speed)
    }
  ]
}
```

Traffic distribution happens automatically. Your application code never knows it's load balanced.

#### Automatic Failover

When your primary provider fails, Bifrost automatically retries with the next provider:

```
Request for gpt-4o
    ↓
Try OpenAI (50% weight) Timeout
    ↓
Try Anthropic (30% weight)
    ↓
Application receives response
(Doesn't know failover happened)
```

This transforms your infrastructure from "system is down if OpenAI is down" to "system stays up even if primary provider is down."

#### Direct Provider Targeting

For use cases where you need a specific provider, you can bypass load balancing:

```
// Load balanced (uses weights)
{"model": "gpt-4o"}

// Direct to provider (bypasses load balancing)
{"model": "openai/gpt-4o"}
```

### 2. Governance Through Virtual Keys

Virtual Keys are the core governance mechanism in Bifrost. They define what each team, application, or user can access:

```
{
  "virtual_key": "vk-engineering-team",
  
  // Which models/providers?
  "allowed_models": ["gpt-4o", "gpt-4o-mini", "claude-3-sonnet"],
  "allowed_providers": ["openai", "anthropic"],
  
  // Budget controls
  "budget": {
    "monthly_spend_limit": "$5,000",
    "alert_thresholds": ["$4,000", "$4,500"],
    "rate_limit": "100 requests per minute"
  },
  
  // Which API keys?
  "allowed_api_keys": ["key-prod-001", "key-fallback-002"],
  
  // MCP tool filtering
  "allowed_mcp_tools": ["github"],
  "blocked_mcp_tools": ["file_system", "subprocess"],
  
  // Security & guardrails
  "guardrails": {
    "pii_detection": true,
    "secret_detection": true,
    "content_safety": "moderate"
  },
  
  // Expiration
  "expires_at": "2026-12-31"
}
```

Now when you create a new user, team, or customer, you don't configure API keys everywhere. You create a Virtual Key and assign it.

### 3. Cost Control & Budgeting

Enterprise AI spending is out of control. Bifrost gives you visibility and control:

#### Per-Request Cost Tracking

Every request flows through the gateway and gets tracked:

```
{
  "request_id": "req-abc-123",
  "virtual_key": "vk-eng-team",
  "model": "gpt-4o",
  "provider": "openai",
  "cost": 0.015,
  "tokens": {"input": 250, "output": 150},
  "latency_ms": 342,
  "status": "success"
}
```

#### Cost Optimization Strategies

With this visibility, you can implement sophisticated strategies:

1. **Route to cheaper providers** when they're available
2. **Use smaller models** for simple tasks (gpt-4o-mini instead of gpt-4o)
3. **Cache responses** for repeated queries
4. **Batch process** non-urgent requests during off-peak hours
5. **Allocate budgets** based on team priorities
6. **Enable MCP Code Mode** for tool orchestration, which reduces token usage by 50% compared to natural language tool invocation delivering significant token cost savings when managing complex multi-tool workflows

### 4. Security & Compliance

Bifrost implements enterprise-grade security at the gateway level:

#### Guardrails

Bifrost supports popular guardrails such as Grey Swan, Patronus AI, Azure, and many others.

Real-time detection and blocking of:

- **Secret Detection**: API keys, passwords, tokens
- **Custom Rules**: Domain-specific policies you define

```
{
  "guardrails": {
    "pii_detection": {
      "enabled": true,
      "action": "block",
      "types": ["credit_card", "email"]
    },
    "secret_detection": {
      "enabled": true,
      "action": "block"
    },
    "content_safety": {
      "provider": "anthropic",
      "threshold": "medium"
    }
  }
}
```

#### Immutable Audit Logs

Every request is logged:

- Who made it (Virtual Key, user ID)
- What was requested (model, prompt)
- Where it went (which provider)
- What happened (success/failure, cost)
- When it happened (timestamp)

### 5. Observability & Monitoring

You can't govern what you can't see. Bifrost provides complete observability:

#### Built-in Dashboards

The Bifrost console shows:

- Real-time request volume and latency
- Cost trends and budget utilization
- Provider health and failover rates
- Error rates and patterns
- Top models and usage patterns

#### Prometheus Metrics

Native Prometheus integration for your monitoring stack:

```
bifrost_requests_total{provider="openai",model="gpt-4o",status="success"} 15234
bifrost_request_duration_seconds{provider="anthropic",quantile="0.95"} 0.342
bifrost_cost_dollars{virtual_key="vk-eng-team"} 1523.45
bifrost_budget_remaining_dollars{virtual_key="vk-eng-team"} 3476.55
bifrost_failover_count{provider="openai"} 23
```

### 6. Semantic Caching

Not all AI requests are the same. Similar questions often get similar answers. Bifrost's semantic cache recognizes this:

```
// Request 1
"Explain machine learning in simple terms"
// → Hits OpenAI, costs $0.03

// Request 2 (semantically similar)
"What is machine learning? Explain simply."
// → Hits cache (semantic match), costs $0.00
```

How it works:

1. Request comes in
2. Bifrost computes semantic embedding
3. Checks cache for semantically similar previous responses
4. If found and confidence > threshold, returns cached response
5. If not found, routes to provider and caches result

This typically **reduces costs 15-25%** without any application changes.

## 💻 Extended with Bifrost Edge

Bifrost Gateway centralizes governance in your infrastructure. But what about AI traffic on employee machines? Claude Desktop, ChatGPT apps, Cursor, browser-based AI?

This is where **Bifrost Edge** enters the picture.

### The Gateway + Edge Architecture

Edge extends Gateway governance to the endpoint:

**Gateway**: Centralizes control for infrastructure-routed traffic

**Edge**: Enforces that same control on endpoint-routed traffic

The governance policies you define in the Gateway automatically apply to all traffic through Edge. No separate configuration needed.

### What Edge Adds to Gateway

**Gateway alone** controls:

- Your backend AI services
- API integrations
- Batch processing jobs

**Gateway + Edge** controls:

- ✅ + Desktop AI applications
- ✅ + Browser-based AI (ChatGPT, etc.)
- ✅ + IDE coding agents
- ✅ + MCP servers and tools
- ✅ + Employee machine AI traffic

Edge is the enforcement layer that makes Gateway governance **truly comprehensive**.
