# Kling AI Performance Tuning

## Overview

Optimize video generation for your use case by choosing the right model, mode, and parameters. Covers benchmarking, speed vs. quality trade-offs, connection pooling, and caching strategies.

## Speed vs. Quality Matrix

| Config | ~Gen Time | Quality | Credits (5s) | Best For |
|--------|-----------|---------|-------------|----------|
| v2.5-turbo + standard | 30-60s | Good | 10 | Drafts, iteration |
| v2-master + standard | 60-90s | High | 10 | Production previews |
| v2.6 + standard | 60-120s | Highest | 10 | Quality-sensitive |
| v2.6 + professional | 120-300s | Highest+ | 35 | Final output |
| v2.6 + prof + audio | 180-400s | Highest+ | 200 | Full production |

## Benchmarking Tool

```python
import time, requests, json

def benchmark_model(prompt: str, model: str, mode: str = "standard",
                    runs: int = 3) -> dict:
    """Benchmark generation time for a model/mode combination."""
    times = []

    for i in range(runs):
        start = time.monotonic()

        # Submit
        r = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
            "model_name": model, "prompt": prompt, "duration": "5", "mode": mode,
        }).json()
        task_id = r["data"]["task_id"]

        # Poll
        while True:
            time.sleep(10)
            result = requests.get(
                f"{BASE}/videos/text2video/{task_id}", headers=get_headers()
            ).json()
            if result["data"]["task_status"] in ("succeed", "failed"):
                break

        elapsed = time.monotonic() - start
        times.append(elapsed)
        print(f"  Run {i+1}/{runs}: {elapsed:.1f}s ({result['data']['task_status']})")

    return {
        "model": model,
        "mode": mode,
        "avg_sec": round(sum(times) / len(times), 1),
        "min_sec": round(min(times), 1),
        "max_sec": round(max(times), 1),
        "runs": runs,
    }

# Compare models
prompt = "A waterfall in a tropical forest, cinematic"
for model in ["kling-v2-5-turbo", "kling-v2-master", "kling-v2-6"]:
    result = benchmark_model(prompt, model, runs=2)
    print(f"{model}: avg={result['avg_sec']}s, min={result['min_sec']}s")
```

## Connection Pooling

```python
import requests

# Without pooling: new TCP connection per request (slow)
# With pooling: reuse connections (fast)

session = requests.Session()
adapter = requests.adapters.HTTPAdapter(
    pool_connections=5,     # number of connection pools
    pool_maxsize=10,        # max connections per pool
    max_retries=3,          # auto-retry on connection errors
)
session.mount("https://", adapter)

# Use session instead of requests directly
response = session.post(f"{BASE}/videos/text2video", headers=get_headers(), json=body)
```

## Prompt Optimization

Prompts that generate faster:

| Technique | Why It Helps |
|-----------|-------------|
| Clear single subject | Less complexity to resolve |
| Specify camera angle | Reduces ambiguity |
| Avoid conflicting styles | "realistic anime" confuses the model |
| Keep under 200 words | Shorter prompts process faster |
| Use negative prompts | Removes processing of unwanted elements |

```python
# Slow prompt (vague, conflicting)
slow = "A scene with many things happening, realistic but also artistic"

# Fast prompt (specific, clear)
fast = "A single red fox walking through snow, side view, natural lighting, 4K"
```

## Caching Strategy

```python
import hashlib

class PromptCache:
    """Cache results to avoid regenerating identical videos."""

    def __init__(self):
        self._cache = {}

    def _key(self, prompt: str, model: str, duration: int, mode: str) -> str:
        raw = f"{prompt}|{model}|{duration}|{mode}"
        return hashlib.sha256(raw.encode()).hexdigest()[:16]

    def get(self, prompt, model, duration, mode):
        key = self._key(prompt, model, duration, mode)
        return self._cache.get(key)

    def set(self, prompt, model, duration, mode, video_url):
        key = self._key(prompt, model, duration, mode)
        self._cache[key] = {
            "url": video_url,
            "cached_at": time.time(),
        }

cache = PromptCache()

def generate_with_cache(prompt, model="kling-v2-master", duration=5, mode="standard"):
    cached = cache.get(prompt, model, duration, mode)
    if cached:
        print(f"Cache hit: {cached['url']}")
        return cached["url"]

    # Generate
    result = client.text_to_video(prompt, model=model, duration=duration, mode=mode)
    url = result["videos"][0]["url"]
    cache.set(prompt, model, duration, mode, url)
    return url
```

## Optimization Checklist

- [ ] Use `kling-v2-5-turbo` for iteration, `v2-6` for final
- [ ] Use `standard` mode until final render
- [ ] Connection pooling via `requests.Session()`
- [ ] Cache identical prompt+param combinations
- [ ] Prompt: specific, single subject, < 200 words
- [ ] Batch submissions paced at 2-3s intervals
- [ ] Use `callback_url` instead of polling
- [ ] Download videos async (don't block on CDN download)
