## Positioning

GPT-4o mini Transcribe is a speech-to-text model optimized for high-accuracy transcription of conversational audio, noisy environments, and multilingual code-switching. Reach for it when you need reliable dictation or translation from audio inputs without sacrificing processing speed.

## About

This is OpenAI's speech-to-text engine, designed to convert audio inputs into text. It handles conversational speech, background noise, and mixed-language audio streams with high accuracy. The model accepts audio input and returns text, with no support for vision, reasoning, or structured outputs.

On Kyma, it runs through an OpenAI-compatible endpoint using a single API key. Requests benefit from automatic failover, routing around degraded serving paths transparently. The platform reports exact request costs in the usage object and identifies the executed model via the X-Kyma-Model header. Prompt caching is supported, billing repeated prefixes at 10% of the standard input rate.

The model operates on a per-minute billing basis and is optimized for fast processing. It does not generate audio or structured JSON, and its context window is limited to 1500 tokens. Signup includes a $0.50 free credit with no card required.

## Use cases

- **Conversational Audio Transcription** — Captures multi-speaker dialogue and natural speech patterns with high accuracy.
- **Noisy Background Dictation** — Filters background interference to produce clean text from field recordings or calls.
- **Mixed Language Audio Processing** — Handles code-switched audio streams like Vietnamese and English in a single pass.

## Not ideal for

Do not use this model for generating audio, running reasoning tasks, or processing files that exceed its 1500-token context limit.

## Pick something else when

- You need a lower-cost option for clear studio recordings → `whisper-v3-turbo`
