GPT-5.4 Mini

Microsoft Learn’s current Foundry Models catalog lists gpt-5.4-mini in the GPT-5.4 series under Azure OpenAI in Microsoft Foundry models. The page states that Azure-sold models are hosted and operated by Azure, billed through the user’s Azure subscription, covered by Azure service-level agreements, and supported by Mic The catalog also says model availability varies by region and cloud and directs readers to deployment-category and region-specific availability pages for exact deployment options. It separately notes that only models listed in the Foundry Agent Service support matrix should be used with Agent Service, so the excerpt co

Microsoft's official "What's new in Microsoft Foundry | March 2026" blog confirms that GPT-5.4 Mini reached general availability on Azure Foundry as the cost-efficient small model in the GPT-5.4 family. It is explicitly positioned as the high-volume tier in a GPT-5.4 routing strategy, targeted at classification, extrac The same announcement places standard GPT-5.4 at $2.50 input / $15 output per million tokens, with GPT-5.4 Pro at $30/$180 for deep analytical workloads, while Mini-specific MSRP is not itemized in the post. As a primary first-party Microsoft source dated April 9, 2026, it is the authoritative reference for Azure avail

The apxml.com catalog page for GPT-5.4 mini lists it as a closed-source, proprietary OpenAI model released on March 16, 2026, with an undisclosed parameter count and architecture, multimodal input, a 400K context length, and API pricing of $0.75 per 1M input tokens and $4.50 per 1M output tokens. The page notes that GP According to the same page, GPT-5.4 mini supports text and image inputs plus tool use, function calling, web search, file search, computer use, and skills, and is available via the API as gpt-5.4-mini. The page also catalogues published benchmark ranks across GPQA, LiveBench categories, Text Arena, WebDev Arena, and Ar

Independent EdTech Innovation Hub coverage dated 19 March 2026 reports that OpenAI released GPT-5.4 mini and GPT-5.4 nano, two smaller models designed for high-volume workloads balancing performance, cost, and latency, announced via a LinkedIn post from OpenAI for Business. The article quotes OpenAI saying: "Today we'r According to the same article, GPT-5.4 mini improves on GPT-5 mini across coding, reasoning, multimodal understanding, and tool use while running more than twice as fast, and approaches the performance of the larger GPT-5.4 model on SWE-Bench Pro and OSWorld-Verified. GPT-5.4 nano is positioned as the smallest, lowest-

Artificial Analysis provides an independent provider benchmark for GPT-5.4 mini (non-reasoning) comparing Azure against OpenAI on output speed, time-to-first-token, and blended price. Azure posts the highest output throughput at 155.5 tokens/second versus OpenAI's 148.8 t/s, but is also the more expensive option at a $ The analysis positions Azure as the throughput-oriented choice for high-volume GPT-5.4 mini deployments while OpenAI wins on cost and latency, giving developers a concrete trade-off matrix for selecting an API provider. Coverage is limited to the non-reasoning variant and only two providers, and the default workload wa
