10 documented Azure Cognitive Services cost inefficiencies, each with how to detect it and how to fix it.
Azure Cognitive ServicesCER-0238
Many Azure OpenAI workloads - such as reporting pipelines, marketing workflows, batch inference jobs, or time-bound customer interactions-only run during specific periods. When PTUs remain fully provisioned 24/7, organizations incur...
Azure Cognitive ServicesCER-0248
Development, testing, QA, and sandbox environments rarely have the steady, predictable traffic patterns needed to justify PTU deployments. These workloads often run intermittently, with lower throughput and shorter usage windows. When PTUs...
Azure Cognitive ServicesCER-0266
When organizations size PTU capacity based on peak expectations or early traffic projections, they often end up with more throughput than regularly required. If real-world usage plateaus below provisioned levels, a portion of the PTU...
Azure Cognitive ServicesCER-0246
Many production Azure OpenAI workloads - such as chatbots, inference services, and retrieval-augmented generation (RAG) pipelines-use PTUs consistently throughout the day. When usage stabilizes after initial experimentation, continuing to...
Azure Cognitive ServicesCER-0254
Azure releases newer OpenAI models that provide better performance and cost characteristics compared to older generations. When workloads remain on outdated model versions, they may consume more tokens to produce equivalent output, run...
Azure Cognitive ServicesCER-0277
Some workloads - such as text classification, keyword extraction, intent detection, routing, or lightweight summarization - do not require the capabilities of the most advanced model families. When high-cost models are used for these...
Azure Cognitive ServicesCER-0510
Azure OpenAI models in Microsoft Foundry (formerly Azure AI services) can be deployed as Global, Data Zone or regional (Standard) pay-per-token deployments. The types differ in where prompts and responses are processed: Global may use any...
Azure Cognitive ServicesCER-0511
Foundry Tools (formerly Azure AI services and Cognitive Services) such as Speech, Translator, Azure Language, Vision OCR and Document Intelligence bill per unit of usage on the default Standard pricing: per audio hour, per million...
Azure Cognitive ServicesCER-0561
A fine-tuned Azure OpenAI model deployed as Standard or Global Standard carries an hourly hosting fee on top of per-token inference, and Microsoft states that the fee applies whether or not any chat completions or Responses API calls are...
Azure Cognitive ServicesCER-0564
Many Azure OpenAI workloads have no user waiting on the answer: nightly document summarization, classification and extraction over large datasets, embedding or enrichment backfills, evaluation runs and bulk content generation. These jobs...
