This guide covers 20 practical tactics to cut LLM API bills by 30-70% without sacrificing output quality. Key strategies include automated prompt compression (LLMLingua), prompt and semantic caching, model routing by task complexity (RouteLLM), explicit output length controls, RAG context trimming, batch processing for non-real-time work, and hard budget gateways via LiteLLM. Additional tips target agentic coding tools like Claude Code and Cursor specifically, covering cache window management, session scoping, MCP server bloat, OpenTelemetry-based cost tracking, and attribution via cloud provider routing. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why does Claude Code cost more for the exact same follow-up prompt after I step away for a few minutes Claude Code's prompt cache window lasts about five minutes; stepping away longer than that causes the entire conversation history, including the roughly 30,000-token base system prompt, to fall out of cache and be reprocessed at full price. In one live demo, a one-line follow-up cost about 2 cents on a cache hit versus about 12 cents after a short idle gap caused a cache miss. _daily.dev surfaces workflow tips like this for developers trying to keep AI coding assistant costs predictable._ ### how much do MCP servers add to my token usage even if the assistant never calls their tools Enabling MCP servers injects their tool definitions into the prompt on every call regardless of whether the tools get used. In one test, adding just two lightweight MCP servers added roughly 1,000 extra input tokens per prompt without the assistant ever touching either tool, which is why auditing enabled servers per project matters. _developers tuning agentic coding setups can track MCP-related cost tradeoffs on daily.dev._ ### how much does routing simple queries to a cheaper LLM model save compared to always using a top-tier model RouteLLM, developed by UC Berkeley's LMSYS team, reports an 85% cost reduction on MT-Bench while retaining 95% of GPT-4-level quality, plus 45% reduction on MMLU and 35% on GSM8K, by using a trained classifier to send simple queries to cheap models and escalate only hard ones. Processing 10,000 support tickets costs roughly $10 with a lightweight model versus $1,300+ with a top-tier reasoning model. _teams deciding between model tiers for cost control can follow LLM routing approaches like this on daily.dev._ ## Similar posts on daily.dev - [How To Reduce LLM Token Costs by 70–90%](https://daily.dev/posts/how-to-reduce-llm-token-costs-by-70-90--lqaosovr2) · C\# Corner · 1 upvotes · 0 comments - [LLM Cost Optimization Strategies That Cut 60-90%](https://daily.dev/posts/llm-cost-optimization-strategies-that-cut-60-90--wv1vkltn8) · portkey · 0 upvotes · 0 comments - [Stop wasting money on AI: 10 ways to cut token usage](https://daily.dev/posts/stop-wasting-money-on-ai-10-ways-to-cut-token-usage-nxjm8tlmo) · LogRocket · 2 upvotes · 0 comments - [5 Open-Source Tools to Control Your AI API Costs at the Code Level](https://daily.dev/posts/5-open-source-tools-to-control-your-ai-api-costs-at-the-code-level-wncyok6uu) · finout · 0 upvotes · 0 comments - [Prompt Compression and Cache Tuning: Cut Your LLM API Costs by 60%](https://daily.dev/posts/prompt-compression-and-cache-tuning-cut-your-llm-api-costs-by-60--llr6ntsis) · SitePoint · 0 upvotes · 0 comments --- Tags: [#llm](https://daily.dev/tags/llm), [#ai-agents](https://daily.dev/tags/ai-agents), [#prompt-engineering](https://daily.dev/tags/prompt-engineering), [#rag](https://daily.dev/tags/rag), [#finops](https://daily.dev/tags/finops) [View this post on daily.dev](https://daily.dev/posts/how-to-reduce-ai-costs-20-llm-token-optimization-tips-with-examples--5pefr2g2r) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How to Reduce AI Costs: 20 LLM Token Optimization Tips (With Examples)","url":"https://daily.dev/posts/how-to-reduce-ai-costs-20-llm-token-optimization-tips-with-examples--5pefr2g2r","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-to-reduce-ai-costs-20-llm-token-optimization-tips-with-examples--5pefr2g2r"},"datePublished":"2026-07-29T19:13:04.954Z","dateModified":"2026-09-14T07:52:38.717Z","description":"Enterprise AI spending is rising despite falling per-token prices, because usage grows faster than costs drop.
