[Cloud Efficiency Hub](https://www.pointfive.co/efficiency-hub) 10 documented Azure Cognitive Services cost inefficiencies, each with how to detect it and how to fix it. ## 10 inefficiencies [All services](https://www.pointfive.co/efficiency-hub#browse-by-service) - Azure Cognitive Services CER-0238 ### [Always-On PTUs for Seasonal or Cyclical Azure OpenAI Workloads](https://www.pointfive.co/efficiency-hub/inefficiencies/always-on-ptus-for-seasonal-or-cyclical-azure-openai-workloads-ccb97) 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... AI - Azure Cognitive Services CER-0248 ### [Non-Production Azure OpenAI Deployments Using PTUs Instead of PAYG](https://www.pointfive.co/efficiency-hub/inefficiencies/non-production-azure-openai-deployments-using-ptus-instead-of-payg-9fe81) 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... AI - Azure Cognitive Services CER-0266 ### [Underutilized PTU Quota for Azure OpenAI Deployments](https://www.pointfive.co/efficiency-hub/inefficiencies/underutilized-ptu-quota-for-azure-openai-deployments-da831) 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... AI - Azure Cognitive Services CER-0246 ### [Missing Reserved PTUs for Steady-State Azure OpenAI Workloads](https://www.pointfive.co/efficiency-hub/inefficiencies/missing-reserved-ptus-for-steady-state-azure-openai-workloads-f78d4) 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... AI - Azure Cognitive Services CER-0254 ### [Suboptimal Azure OpenAI Model Type](https://www.pointfive.co/efficiency-hub/inefficiencies/suboptimal-azure-openai-model-type-c8913) 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 When workloads remain on outdated model versions, they may consume more tokens to produce equivalent output, run... AI - Azure Cognitive Services CER-0277 ### [Using High-Cost Models for Low-Complexity Tasks in Azure OpenAI](https://www.pointfive.co/efficiency-hub/inefficiencies/using-high-cost-models-for-low-complexity-tasks-cc721) 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... AI - Azure Cognitive Services CER-0510 ### [Regional Standard Azure OpenAI Deployments Without a Data Residency Requirement](https://www.pointfive.co/efficiency-hub/inefficiencies/regional-standard-azure-openai-deployments-without-a-data-residency-requirement) 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...

AI - Azure Cognitive Services CER-0561 ### [Low-Traffic Fine-Tuned Azure OpenAI Deployments Accruing Hosting Fees](https://www.pointfive.co/efficiency-hub/inefficiencies/low-traffic-fine-tuned-azure-openai-deployments-accruing-hosting-fees) 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... AI - Azure Cognitive Services CER-0564 ### [Latency-Tolerant Azure OpenAI Workloads Not Using Batch Deployments](https://www.pointfive.co/efficiency-hub/inefficiencies/latency-tolerant-azure-openai-workloads-not-using-batch-deployments) 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...
