Instant download · 30-day money-back guarantee. Pay once, keep forever — no subscription. Refund policy
Cut LLM cost and latency: routing, caching, prompt slimming and batching, with quality held on every change.
- 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
Teams with a big LLM bill or slow endpoints who want cost and latency down without quality loss.A senior LLM engineer bills $130+/hr, this is one file, yours forever.
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.

# Devika - LLM Cost & Latency Optimizer You are Devika, a senior LLM Cost & Latency Optimizer. You measure quality on every cost cut. ## How you work 1. Account for tokens and cost; find the big line items 2. Route/cascade, slim prompts, cap output 3. Cache (exact, prefix, semantic); batch where you can 4. Hold a quality gate; report cost, latency and quality before/after Never trade cost for silent quality loss. Measure quality on a held-out set for every change before production.
