How it works

📎 devika-llm-cost-latency-optimizer.skillLOADED ✓
LLM feature costs $23k/month, 80% from one summarization endpoint on a frontier model. CFO wants it halved, quality intact. Options?
CLAUDE · WITH THIS SKILL Summarization is the easiest cascade win in the book - route by document complexity: a small model takes the 70% of simple docs, escalate to the frontier model on low confidence or length triggers. Before that, the token audit: most summarization prompts drag a bloated system preamble and full few-shots on every call; prompt slimming alone is usually worth 25-30%, prompt caching on the shared prefix stacks on top. The rule: build the quality eval first - 100 docs, scored - so every cut is measured, not vibes. Realistic combined saving: 55-70%. What's your document length distribution?

What you're actually buying

Drop Devika into Claude and get a senior cost and latency optimizer who cuts spend and tail latency while measuring quality on every change.

Devika cuts the cost and latency of LLM features without wrecking quality: token accounting and cost modeling, model routing and cascades (cheap model first, escalate on low confidence), prompt slimming (shorter prompts, fewer and better few-shots, output-length control, structured output), caching (exact, prefix and semantic with thresholds), batching, retrieval trimming, streaming for perceived latency, and quantization tradeoffs, always with a quality gate so you never trade cost for silent quality loss. Tools like LiteLLM, Helicone, Langfuse and tiktoken, without lock-in. Measure quality on a held-out set for every cost cut.

What you get

  • →Token accounting and a cost model that finds the big line items
  • →Model routing/cascades and prompt slimming
  • →Exact, prefix and semantic caching with thresholds
  • →A quality gate on every cost cut, with before/after numbers

What does the Devika skill do?+

Cut LLM cost and latency: routing, caching, prompt slimming and batching, with quality held on every change. Load it once into Claude Projects and you get a configured LLM Cost & Latency Optimizer without re-explaining context at the start of every session. Build and evaluate against a held-out test set in a development or staging environment, add guardrails, cost and rate limits, and human review, and roll out behind evals and monitoring before serving agents or LLM features in production.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

How is this different from using Claude without the Devika skill?+

Without a skill file your AI starts every session as a general assistant. With Devika loaded it applies LLM Cost & Latency Optimizer methodology from the first message, with consistent quality every time. Build and evaluate against a held-out test set in a development or staging environment, add guardrails, cost and rate limits, and human review, and roll out behind evals and monitoring before serving agents or LLM features in production.
