Quick Start

1. Get API Key

# Sign up at https://openrouter.ai/keys
export OPENROUTER_API_KEY="sk-or-v1-..."

2. Basic Chat Completion

import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://openrouter.ai/api/v1',
  apiKey: process.env.OPENROUTER_API_KEY,
  defaultHeaders: {
    'HTTP-Referer': 'https://your-app.com',  // Optional
    'X-Title': 'Your App Name',              // Optional
  }
});

async function chat() {
  const completion = await client.chat.completions.create({
    model: 'anthropic/claude-3.5-sonnet',
    messages: [
      { role: 'user', content: 'Explain quantum computing in simple terms' }
    ],
  });

  console.log(completion.choices[0].message.content);
}

3. Streaming Response

async function streamChat() {
  const stream = await client.chat.completions.create({
    model: 'openai/gpt-4-turbo',
    messages: [
      { role: 'user', content: 'Write a short story about AI' }
    ],
    stream: true,
  });

  for await (const chunk of stream) {
    const content = chunk.choices[0]?.delta?.content || '';
    process.stdout.write(content);
  }
}

Model Selection Strategy

Available Model Categories

Flagship Models (Highest Quality):

const flagshipModels = {
  claude: 'anthropic/claude-3.5-sonnet',      // Best reasoning
  gpt4: 'openai/gpt-4-turbo',                 // Best general purpose
  gemini: 'google/gemini-pro-1.5',            // Best long context
  opus: 'anthropic/claude-3-opus',            // Best complex tasks
};

Fast Models (Low Latency):

const fastModels = {
  claude: 'anthropic/claude-3-haiku',         // Fastest Claude
  gpt35: 'openai/gpt-3.5-turbo',             // Fast GPT
  gemini: 'google/gemini-flash-1.5',         // Fast Gemini
  llama: 'meta-llama/llama-3.1-8b-instruct', // Fast open source
};

Cost-Optimized Models :

const budgetModels = {
  haiku: 'anthropic/claude-3-haiku',          // $0.25/$1.25 per 1M tokens
  gemini: 'google/gemini-flash-1.5',         // $0.075/$0.30 per 1M tokens
  llama: 'meta-llama/llama-3.1-8b-instruct', // $0.06/$0.06 per 1M tokens
  mixtral: 'mistralai/mixtral-8x7b-instruct', // $0.24/$0.24 per 1M tokens
};

Specialized Models :

const specializedModels = {
  vision: 'openai/gpt-4-vision-preview',     // Image understanding
  code: 'anthropic/claude-3.5-sonnet',       // Code generation
  longContext: 'google/gemini-pro-1.5',      // 2M token context
  function: 'openai/gpt-4-turbo',            // Function calling
};

Model Selection Logic

interface ModelSelector {
  task: 'chat' | 'code' | 'vision' | 'function' | 'summary';
  priority: 'quality' | 'speed' | 'cost';
  maxCost?: number;  // Max cost per 1M tokens
  contextSize?: number;
}

function selectModel(criteria: ModelSelector): string {
  if (criteria.task === 'vision') {
    return 'openai/gpt-4-vision-preview';
  }

  if (criteria.task === 'code') {
    return criteria.priority === 'quality'
      ? 'anthropic/claude-3.5-sonnet'
      : 'meta-llama/llama-3.1-70b-instruct';
  }

  if (criteria.contextSize && criteria.contextSize > 100000) {
    return 'google/gemini-pro-1.5';  // 2M context
  }

  // Default selection by priority
  switch (criteria.priority) {
    case 'quality':
      return 'anthropic/claude-3.5-sonnet';
    case 'speed':
      return 'anthropic/claude-3-haiku';
    case 'cost':
      return criteria.maxCost && criteria.maxCost < 0.5
        ? 'google/gemini-flash-1.5'
        : 'anthropic/claude-3-haiku';
    default:
      return 'openai/gpt-4-turbo';
  }
}

// Usage
const model = selectModel({
  task: 'code',
  priority: 'quality',
});

Function Calling

Basic Function Calling

const tools = [
  {
    type: 'function',
    function: {
      name: 'get_weather',
      description: 'Get current weather for a location',

        ],
        tools,
      });

      console.log(followUp.choices[0].message.content);
    }
  }
}

Multi-Step Function Calling

async function multiStepFunctionCall(userQuery: string) {
  const messages = [{ role: 'user', content: userQuery }];
  let iterationCount = 0;
  const maxIterations = 5;

  while (iterationCount < maxIterations) {

  throw new Error('Max iterations reached');
}

Cost Optimization

Token Counting and Cost Estimation

import { encoding_for_model } from 'tiktoken';

interface CostEstimate {
  promptTokens: number;
  completionTokens: number;
  promptCost: number;
  completionCost: number;
  totalCost: number;
}

const modelPricing = {
  'anthropic/claude-3.5-sonnet': { input: 3.00, output: 15.00 },  // per 1M tokens
  'anthropic/claude-3-haiku': { input: 0.25, output: 1.25 },
  'openai/gpt-4-turbo': { input: 10.00, output: 30.00 },
  'openai/gpt-3.5-turbo': { input: 0.50, output: 1.50 },
  'google/gemini-flash-1.5': { input: 0.075, output: 0.30 },
};

function estimateCost(
  prompt: string,
  expectedCompletion: number,
  model: string
): CostEstimate {
  const encoder = encoding_for_model('gpt-4');  // Approximation
  const promptTokens = encoder.encode(prompt).length;
  const completionTokens = expectedCompletion;

  const pricing = modelPricing[model] || { input: 0, output: 0 };

  const promptCost = (promptTokens / 1_000_000) * pricing.input;
  const completionCost = (completionTokens / 1_000_000) * pricing.output;

  return {
    promptTokens,
    completionTokens,
    promptCost,
    completionCost,
    totalCost: promptCost + completionCost,
  };
}

// Usage
const estimate = estimateCost(
  'Explain quantum computing',
  500,  // Expected response tokens
  'anthropic/claude-3.5-sonnet'
);

console.log(`Estimated cost: $${estimate.totalCost.toFixed(4)}`);

Dynamic Model Selection by Budget

async function budgetOptimizedChat(
  prompt: string,
  maxCostPerRequest: number = 0.01  // $0.01 max
) {
  // Estimate with expensive model
  const expensiveEstimate = estimateCost(
    prompt,
    1000,
    'anthropic/claude-3.5-sonnet'
  );

  let selectedModel = 'anthropic/claude-3.5-sonnet';

  if (expensiveEstimate.totalCost > maxCostPerRequest) {
    // Try cheaper models
    const cheapEstimate = estimateCost(
      prompt,
      1000,
      'anthropic/claude-3-haiku'
    );

    if (cheapEstimate.totalCost > maxCostPerRequest) {
      selectedModel = 'google/gemini-flash-1.5';
    } else {
      selectedModel = 'anthropic/claude-3-haiku';
    }
  }

  console.log(`Selected model: ${selectedModel}`);

  const completion = await client.chat.completions.create({
    model: selectedModel,
    messages: [{ role: 'user', content: prompt }],
  });

  return completion.choices[0].message.content;
}

Batching for Cost Reduction

async function batchProcess(prompts: string[], model: string) {
  // Process multiple prompts in parallel with rate limiting
  const concurrency = 5;
  const results = [];

  for (let i = 0; i < prompts.length; i += concurrency) {
    const batch = prompts.slice(i, i + concurrency);

    const batchResults = await Promise.all(
      batch.map(prompt =>
        client.chat.completions.create({
          model,
          messages: [{ role: 'user', content: prompt }],
          max_tokens: 500,  // Limit tokens to control cost
        })
      )
    );

    results.push(...batchResults);

    // Rate limiting delay
    if (i + concurrency < prompts.length) {
      await new Promise(resolve => setTimeout(resolve, 1000));
    }
  }

  return results;
}

Model Fallback and Retry Strategy

Automatic Fallback

const modelFallbackChain = [
  'anthropic/claude-3.5-sonnet',
  'openai/gpt-4-turbo',
  'anthropic/claude-3-haiku',
  'google/gemini-flash-1.5',
];

async function chatWithFallback(
  prompt: string,
  maxRetries: number = 3
): Promise<string> {
  for (const model of modelFallbackChain) {
    try {
      console.log(`Trying model: ${model}`);

      const completion = await client.chat.completions.create({
        model,
        messages: [{ role: 'user', content: prompt }],
        max_tokens: 2000,
      });

      return completion.choices[0].message.content || '';
    } catch (error) {
      console.warn(`Model ${model} failed:`, error);

      // Continue to next model
      if (model === modelFallbackChain[modelFallbackChain.length - 1]) {
        throw new Error('All models failed');
      }
    }
  }

  throw new Error('No models available');
}

Exponential Backoff for Rate Limits

async function retryWithBackoff<T>(
  fn: () => Promise<T>,
  maxRetries: number = 5
): Promise<T> {
  let lastError: Error;

  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      lastError = error as Error;

      // Check if rate limit error
      if (error.status === 429) {
        const delay = Math.pow(2, i) * 1000;  // Exponential backoff
        console.log(`Rate limited. Retrying in ${delay}ms...`);
        await new Promise(resolve => setTimeout(resolve, delay));
      } else {
        throw error;  // Non-retryable error
      }
    }
  }

  throw lastError!;
}

// Usage
const result = await retryWithBackoff(() =>
  client.chat.completions.create({
    model: 'anthropic/claude-3.5-sonnet',
    messages: [{ role: 'user', content: 'Hello' }],
  })
);

const systemPrompts = {
  concise: 'You are a helpful assistant. Be concise and direct.',
  detailed: 'You are a knowledgeable expert. Provide comprehensive answers with examples.',
  code: 'You are an expert programmer. Provide clean, well-commented code with explanations.',
  creative: 'You are a creative writing assistant. Be imaginative and engaging.',
};

async function chatWithPersonality(
  prompt: string,
  personality: keyof typeof systemPrompts
) {

      { role: 'user', content: prompt },
    ],
  });

  return completion.choices[0].message.content;
}

Few-Shot Prompting

async function fewShotClassification(text: string) {
  const completion = await client.chat.completions.create({
    model: 'openai/gpt-4-turbo',
    messages: [

async function reasoningTask(problem: string) {
  const completion = await client.chat.completions.create({
    model: 'anthropic/claude-3.5-sonnet',
    messages: [
      {
        role: 'user',
        content: `${problem}\n\nLet's solve this step by step:\n1.`,
      },
    ],
    max_tokens: 3000,
  });

  return completion.choices[0].message.content;
}

Rate Limits and Throttling

Rate Limit Handler

class RateLimitedClient {
  private requestQueue: Array<() => Promise<any>> = [];
  private processing = false;
  private requestsPerMinute = 60;
  private requestInterval = 60000 / this.requestsPerMinute;

  async enqueue<T>(request: () => Promise<T>): Promise<T> {
    return new Promise((resolve, reject) => {
      this.requestQueue.push(async () => {
        try {
          const result = await request();
          resolve(result);
        } catch (error) {
          reject(error);
        }
      });

      this.processQueue();
    });
  }

  private async processQueue() {
    if (this.processing || this.requestQueue.length === 0) return;

    this.processing = true;

    while (this.requestQueue.length > 0) {
      const request = this.requestQueue.shift()!;
      await request();
      await new Promise(resolve => setTimeout(resolve, this.requestInterval));
    }

    this.processing = false;
  }
}

// Usage
const rateLimitedClient = new RateLimitedClient();

const result = await rateLimitedClient.enqueue(() =>
  client.chat.completions.create({
    model: 'anthropic/claude-3.5-sonnet',
    messages: [{ role: 'user', content: 'Hello' }],

    model: 'openai/gpt-4-vision-preview',
    messages: [
      {
        role: 'user',
        content: [
          { type: 'text', text: question },
          { type: 'image_url', image_url: { url: imageUrl } },
        ],
      },
    ],
    max_tokens: 1000,
  });

  return completion.choices[0].message.content;

            image_url: { url },
          })),
        ],
      },
    ],
  });

  return completion.choices[0].message.content;
}

Error Handling and Monitoring

Comprehensive Error Handler

interface ErrorResponse {
  error: {
    message: string;

Request/Response Logging

class LoggingClient {
  async chat(prompt: string, model: string) {
    const startTime = Date.now();

    console.log('[Request]', {
      timestamp: new Date().toISOString(),
      model,
      promptLength: prompt.length,
    });

    try {
      const completion = await client.chat.completions.create({
        model,
        messages: [{ role: 'user', content: prompt }],
      });

      const duration = Date.now() - startTime;

      console.log('[Response]', {
        timestamp: new Date().toISOString(),
        duration,
        usage: completion.usage,
        finishReason: completion.choices[0].finish_reason,
      });

      return completion;
    } catch (error) {
      console.error('[Error]', {
        timestamp: new Date().toISOString(),
        duration: Date.now() - startTime,
        error,
      });
      throw error;
    }
  }
}

Best Practices

1. Model Selection :

   • Use fast models (Haiku, Flash) for simple tasks
   • Use flagship models (Sonnet, GPT-4) for complex reasoning
   • Consider context size requirements
   • Test multiple models for your use case

2. Cost Optimization :

   • Estimate costs before requests
   • Use cheaper models when possible
   • Implement token limits
   • Cache common responses
   • Batch similar requests

3. Streaming :

   • Always use streaming for user-facing apps
   • Handle connection interruptions
   • Show progress indicators
   • Buffer partial responses

4. Error Handling :

   • Implement retry logic with exponential backoff
   • Use model fallbacks for reliability
   • Log all errors for debugging
   • Handle rate limits gracefully

5. Prompt Engineering :

   • Use system prompts for consistency
   • Implement few-shot learning for specific tasks
   • Use chain-of-thought for complex reasoning
   • Keep prompts concise to reduce costs

6. Rate Limiting :

   • Respect API rate limits

Common Pitfalls

❌ Exposing API keys in frontend :

// WRONG - API key exposed
const client = new OpenAI({
  baseURL: 'https://openrouter.ai/api/v1',
  apiKey: 'sk-or-v1-...',  // Exposed!
});

✅ Correct - Server-side proxy :

// Backend proxy
app.post('/api/chat', async (req, res) => {
  const { prompt } = req.body;

  const completion = await client.chat.completions.create({
    model: 'anthropic/claude-3.5-sonnet',
    messages: [{ role: 'user', content: prompt }],
  });

  res.json(completion);
});

❌ Not handling streaming errors :

// WRONG - no error handling
for await (const chunk of stream) {
  console.log(chunk.choices[0].delta.content);
}

✅ Correct - with error handling :

try {
  for await (const chunk of stream) {
    const content = chunk.choices[0]?.delta?.content || '';
    process.stdout.write(content);
  }
} catch (error) {
  console.error('Stream error:', error);
  // Implement retry or fallback
}

❌ Ignoring rate limits :

// WRONG - no rate limiting
const promises = prompts.map(prompt => chat(prompt));
await Promise.all(promises);  // May hit rate limits

✅ Correct - with rate limiting :

const results = [];
for (let i = 0; i < prompts.length; i += 5) {
  const batch = prompts.slice(i, i + 5);
  const batchResults = await Promise.all(batch.map(chat));
  results.push(...batchResults);
  await new Promise(r => setTimeout(r, 1000));  // Delay between batches
}

Performance Optimization

Caching Responses

const responseCache = new Map<string, string>();

async function cachedChat(prompt: string, model: string) {
  const cacheKey = `${model}:${prompt}`;

  if (responseCache.has(cacheKey)) {
    console.log('Cache hit');
    return responseCache.get(cacheKey)!;
  }

  const completion = await client.chat.completions.create({
    model,
    messages: [{ role: 'user', content: prompt }],
  });

  const response = completion.choices[0].message.content || '';
  responseCache.set(cacheKey, response);

  return response;
}

Parallel Processing

async function parallelChat(prompts: string[], model: string) {
  const results = await Promise.all(
    prompts.map(prompt =>
      client.chat.completions.create({
        model,
        messages: [{ role: 'user', content: prompt }],
      })
    )
  );

  return results.map(r => r.choices[0].message.content);
}
