Comparison guides for teams choosing providers, routing layers, and managed AI platforms.
Topic overview
Start with the most useful StackSpend guides for this problem area, then move into the product workflow that fits what you are trying to do.
AWS Bedrock and Google Vertex AI are not priced like a single-model API. Compare why platform, region, model, and throughput choices matter more than the headline rates most teams start with.
Read articleShould you route through Hugging Face or call model providers directly? Compare credits, pass-through billing, endpoint costs, operational trade-offs, and when each approach is actually cheaper.
Read articleLLMOps and LLM FinOps overlap, but they are not the same job. Learn where tracing, prompts, evaluation, spend tracking, and cost controls fit in a modern AI operations stack.
Read articleA practical comparison of Amazon Bedrock, Vertex AI, and Azure OpenAI for developers and product teams. What each platform does well, where costs show up, and when to choose which.
Read articleA practical decision guide for developers choosing between direct model APIs and an AI gateway. When a gateway helps, when it adds unnecessary complexity, and how to decide based on traffic, routing, and cost control.
Read articleOpen-weight models now rival the closed frontier on quality — but whether they're actually cheaper depends entirely on how you host and measure them. Here's how to track the true, blended cost of open and closed models in one view using Hugging Face and StackSpend.
Read articleA practical guide to choosing AWS, GCP, or Azure. Cost patterns, strengths by workload, and how to decide when you're starting fresh or already multi-cloud.
Read articleImprove RAG quality by treating retrieval as a funnel: lexical search, dense retrieval, reranking, and only then generation.
Read articleMany LLM question-answering systems should be grounded in SQL, tools, or explicit evidence rather than treated like generic RAG.
Read articleBuild tool-using LLM systems with the lightest orchestration that works: fixed workflows first, planner and executor loops only when the task truly requires them.
Read articleOn Hugging Face, the biggest cost surprise is usually a GPU-backed Inference Endpoint or Space left running after testing. How GPU cost accumulates and how to catch it.
Read articleThe cost and attribution consequences of putting a gateway in front of your model providers — what consolidating billing gains you, and what per-model visibility it can cost.
