A bottom-up TCO model for a RAG app serving 1M requests/month shows inference is 81% of total cost on a single-provider stack ($2,502/month total) but only 34% on a multi-provider stack ($5,920/month total). The gap comes entirely from cross-provider egress fees ($135/month) and operational overhead (32 engineer-hours/month at $95/hour = $3,040). DigitalOcean's Deploy 2026 TCO comparison for a 1M-bookings/month corporate travel agent shows $67,727/month vs $84,827 for Baseten+AWS and $110,337 for AWS AgentCore. The article provides a transparent, adjustable line-item model and recommends starting with serverless inference, moving to dedicated only when utilization justifies it, and using batch inference for latency-tolerant workloads to cut costs up to 50%. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What percentage of total cost does LLM inference represent in a production RAG application? Inference represents 81% of total cost for a consolidated single-provider RAG application serving 1M requests per month, but only 34% for the identical workload split across two providers. The difference comes from cross-provider egress fees ($135/month) and operational overhead (32 engineer-hours/month at $95/hour, or $3,040), neither of which appears in per-token pricing comparisons. _Anyone modeling inference spend against total stack cost can track these cost breakdowns on daily.dev before committing to an architecture._ ### How much cheaper is a single-provider AI stack compared to a multi-cloud AWS setup? DigitalOcean's AI-Native Cloud was priced at $67,727/month for a 1M-bookings/month travel agent workload, versus $84,827 for Baseten+AWS (20% more) and $110,337 for AWS AgentCore (39% more), according to figures published at Deploy 2026. The gap comes mainly from cross-provider egress fees and duplicated operational overhead across billing and security relationships. _Teams comparing cloud vendors for AI workloads can weigh these published TCO figures alongside their own numbers via daily.dev._ ### When should I move LLM inference workloads from serverless to dedicated GPU capacity? Move to dedicated capacity only once steady-state throughput makes a reserved GPU's hourly cost cheaper than the equivalent per-token bill at your utilization, since a reserved GPU bills 24 hours a day regardless of traffic. A common costly mistake is buying dedicated capacity early for predictability and running it at only 10% utilization, paying roughly ten times the effective per-token rate. _Developers weighing serverless versus dedicated inference can revisit this crossover math on daily.dev before provisioning GPUs._ ## Similar posts on daily.dev - [The real cost of agentic AI](https://daily.dev/posts/the-real-cost-of-agentic-ai-q32iamekb) · InfoWorld · 0 upvotes · 0 comments - [Cheapest Batch Inference for Low-Cost AI Inference: 6 Providers Compared \(2026\)](https://daily.dev/posts/cheapest-batch-inference-for-low-cost-ai-inference-6-providers-compared-2026--urh3juuuq) · DigitalOcean Community · 0 upvotes · 0 comments - [AI inference is obviously profitable](https://daily.dev/posts/ai-inference-is-obviously-profitable-4xqzohtxz) · sean goedecke · 16 upvotes · 4 comments - [Blog: The Self-Hosting Threshold: When SaaS Teams Should Bring AI Inference In-House](https://daily.dev/posts/blog-the-self-hosting-threshold-when-saas-teams-should-bring-ai-inference-in-house-f8ausmdhi) · Wawandco · 2 upvotes · 0 comments --- Tags: [#llm](https://daily.dev/tags/llm), [#rag](https://daily.dev/tags/rag), [#ai-inference](https://daily.dev/tags/ai-inference), [#digitalocean](https://daily.dev/tags/digitalocean) [View this post on daily.dev](https://daily.dev/posts/what-a-production-ai-application-actually-costs-inference-in-production-series-bojhh3338) ```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":"What a Production AI Application Actually Costs: Inference in Production Series","url":"https://daily.dev/posts/what-a-production-ai-application-actually-costs-inference-in-production-series-bojhh3338","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/what-a-production-ai-application-actually-costs-inference-in-production-series-bojhh3338"},"datePublished":"2026-08-07T17:42:45.361Z","dateModified":"2026-09-14T09:12:18.624Z","description":"Token pricing alone is a misleading metric for AI application costs.
