Token Optimization Strategies

# Strategy 1: Tiered Model Routing
class TieredRouter:
    """Route requests to appropriate model based on complexity."""

    def route(self, task_complexity: str, content: str) -> str:
        if task_complexity == "simple":
            return self.call_gpt4o_mini(content)  # 10x cheaper
        elif task_complexity == "standard":
            return self.call_claude_haiku(content)  # 5x cheaper
        else:
            return self.call_gpt4o(content)  # Full capability

# Strategy 2: Prompt Compression
class PromptCompressor:
    """Compress prompts to reduce token usage."""

    def compress(self, prompt: str) -> str:
        # Remove unnecessary whitespace
        compressed = " ".join(prompt.split())

        # Use abbreviations for common terms
        replacements = {
            "artificial intelligence": "AI",
            "machine learning": "ML",
            "large language model": "LLM",
        }

        for full, short in replacements.items():
            compressed = compressed.replace(full, short)

        return compressed

# Strategy 3: Response Streaming
async def stream_response(prompt: str):
    """Stream response to show progress and allow early termination."""
    chunks = []
    async for chunk in llm.stream(prompt):
        chunks.append(chunk)
        if should_stop_early(chunks):
            break
    return "".join(chunks)

Cost Optimization Patterns

Smart Caching

import hashlib
from functools import lru_cache

class LLMCache:
    """Cache LLM responses to avoid redundant calls."""

    def __init__(self, ttl_seconds=3600):
        self.cache = {}
        self.ttl = ttl_seconds

    def _get_key(self, prompt: str, model: str, params: dict) -> str:
        """Generate cache key from request."""
        content = f"{prompt}:{model}:{sorted(params.items())}"
        return hashlib.sha256(content.encode()).hexdigest()

    def get(self, prompt: str, model: str, params: dict):
        key = self._get_key(prompt, model, params)
        if key in self.cache and not self._is_expired(key):
            return self.cache[key]["response"]
        return None

    def set(self, prompt: str, model: str, params: dict, response: str):
        key = self._get_key(prompt, model, params)
        self.cache[key] = {
            "response": response,
            "timestamp": time.time()
        }

Request Batching

class BatchProcessor:
    """Batch multiple requests to reduce API overhead."""

    def __init__(self, max_batch_size=10, max_wait_ms=100):
        self.batch = []
        self.max_batch_size = max_batch_size
        self.max_wait_ms = max_wait_ms

    async def submit(self, request: dict) -> str:
        future = asyncio.Future()
        self.batch.append({"request": request, "future": future})

        if len(self.batch) >= self.max_batch_size:
            await self._flush()

        return await future

    async def _flush(self):
        """Process batched requests."""
        if not self.batch:
            return

        # Combine requests into single prompt
        combined_prompt = self._combine_prompts(self.batch)

        # Single API call for all requests
        response = await llm.call(combined_prompt)

        # Distribute responses
        for item, result in zip(self.batch, self._split_responses(response)):
            item["future"].set_result(result)

        self.batch = []

Usage Monitoring

class UsageTracker:
    """Track and analyze LLM usage for cost optimization."""

    def __init__(self):
        self.usage_log = []

    def log_request(self, model: str, input_tokens: int, output_tokens: int, cost: float):
        self.usage_log.append({
            "timestamp": datetime.now(),
            "model": model,

            "output_tokens": output_tokens,
            "cost": cost
        })

    def get_daily_costs(self) -> dict:
        """Aggregate costs by day."""
        daily = defaultdict(float)
        for entry in self.usage_log:
            day = entry["timestamp"].date()
            daily[day] += entry["cost"]
        return dict(daily)

    def get_model_breakdown(self) -> dict:
        """Get cost breakdown by model."""
        breakdown = defaultdict(lambda: {"cost": 0, "requests": 0})
        for entry in self.usage_log:
            model = entry["model"]
            breakdown[model]["cost"] += entry["cost"]
            breakdown[model]["requests"] += 1
        return dict(breakdown)

    def identify_optimization_opportunities(self) -> list:

        # Find expensive models used for simple tasks

                    })

        return opportunities

Best Practices

1. Always Set Token Limits

response = llm.chat(
    messages=messages,
    max_tokens=500,  # Prevent runaway costs
    temperature=0.7
)

2. Use System Prompts Effectively

system_prompt = """You are a concise assistant. Keep responses under 3 sentences unless asked for detail."""

# This reduces output tokens significantly

3. Implement Retry Logic with Exponential Backoff

@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10))
def call_llm_with_retry(prompt: str):
    return llm.call(prompt)

4. Monitor and Alert on Costs

# cost-alerts.yml
budgets:
  daily_limit: $100
  alert_thresholds: [50, 80, 100]

anomaly_detection:
  enabled: true
  baseline_window: 7_days
  threshold_multiplier: 3

alerts:
  channels:
    - slack: #ai-ops-alerts
    - email: ai-ops@company.com
