Running speech recognition
Whisper is a Speech-To-Text model from OpenAI. Given an audio file with voice data it produces human speech recognition text with per sentence timestamps. There are different model sizes (small, base, large, etc.) and variants for English, see more at deepinfra.com. By default, Whisper produces by sentence timestamp segmentation. We also host whisper-timestamped that can provide timestamps for words in the audio. You can use it with our REST API. Here's how to use it:
curl -X POST \
-F "audio=@/home/user/all-in-01.mp3" \
-H "Authorization: Bearer YOUR_API_KEY" \
'https://api.deepinfra.com/v1/inference/openai/whisper-timestamped-medium.en'
To see additional parameters and how to call this model, check out the documentation page for complete API reference and examples.

Function Calling in DeepInfra: Extend Your AI with Real-World Logic<p>Modern large language models (LLMs) are incredibly powerful at understanding and generating text, but until recently they were largely static: they could only respond based on patterns in their training data. Function calling changes that. It lets language models interact with external logic — your own code, APIs, utilities, or business systems — while still […]</p>
DeepSeek V4 Pro: Model Overview, Features & Performance Guide<p>DeepSeek V4 Pro is a 1.6-trillion parameter Mixture-of-Experts (MoE) model from DeepSeek, released on April 24, 2026 under the MIT license. It is designed for advanced reasoning, complex software engineering, and long-running agentic tasks, and arrives alongside DeepSeek-V4-Flash, a lighter 284B-parameter variant built for faster, lower-cost inference. The V4 series is DeepSeek’s first two-tier lineup […]</p>
