New OpenAI Transcription Models Now Available in WhisperUI
WhisperUI is excited to announce the addition of two cutting-edge OpenAI transcription models—gpt-4o-transcribe and gpt-4o-mini-transcribe—to our platform. These models join the existing whisper-1 option, giving users more flexibility and performance choices. Here's what you need to know about each model, how they differ, and how to choose the best one for your needs.
🔧 What’s Changed?
Users of WhisperUI can now select between:
- whisper-1 (the initial model for WhisperUI)
- gpt 4o-mini-transcribe (smaller, faster, lightweight, cheaper)
- gpt 4o-transcribe (state-of-the-art accuracy)
Whether you're working with noisy audio, multiple accents, or need fast transcription, we've got you covered.
Model Overview & Comparisons
whisper-1
- Proven & Reliable: Based on OpenAI’s foundational speech-to-text model launched in 2022.
- Strengths: Solid performance on clean audio.
- Drawbacks: Can struggle with accents, background noise, or complex speech patterns.
gpt 4o-mini-transcribe
-
Lightweight & Efficient: Built on the GPT-4o-mini architecture—an 8B-parameter model optimized for speed and cost-effectiveness.
-
Advantages:
- Excellent for shorter clips and real-time applications.
- Lower token costs than full GPT 4o.
-
Accuracy: Outperforms Whisper 1 in most cases, but can sometimes truncate longer transcripts or produce occasional minor hiccups.
gpt 4o-transcribe
-
Top-Tier Accuracy: Achieves significantly lower Word Error Rates (WER) across benchmarks like FLEURS compared to Whisper models.
-
Best For:
- Multilingual transcriptions.
- Audio with heavy background noise or diverse accents.
- Professional use cases like meeting notes, interviews, or call-center data.
-
Trade-Offs: Slightly slower and more resource-intensive than the mini variant—but worth it when accuracy is critical.
Technical Enhancements Behind GPT 4o Models
OpenAI’s release highlights several key innovations that power these new models:
-
Pretraining on High-Quality Audio Extensive exposure to diverse, real-world audio data enhances nuance recognition and robustness.
-
Reinforcement Learning for Accuracy Unique training techniques reduce transcription hallucinations and errors through reinforcement learning.
-
Advanced Distillation Knowledge from large GPT 4o models distilled into smaller, performant versions (like GPT 4o-mini).
These translate to noticeable improvements: reduced misrecognitions, solid performance in noise, and better multilingual handling.
Choosing a Model: A Quick Guide
Clean audio, basic transcription needs
- Recommended Model: whisper-1
- Why: Reliable, efficient, with minimal overhead.

- Why: Best-in-class transcription, handles complexity extremely well.
How It Works in WhisperUI
Using the new models in WhisperUI is easy:
- Upload your audio as usual.
- In the model dropdown, select Whisper 1, gpt 4o-mini-transcribe, or gpt 4o-transcribe.
- Run the transcription—results will display instantly on your dashboard.
Why This Matters
Integrating GPT 4o transcription models aligns with WhisperUI’s mission: accurate, flexible, and user-friendly audio transcription. By offering these state-of-the-art options, we:
- Empower users with the choice between speed, cost, and precision.
- Meet diverse workflows, from quick voice notes to enterprise multilingual transcription.
- Stay at the forefront of transcription technology, thanks to OpenAI’s SOTA models.
WhisperUI now supports three transcription engines:
- Whisper 1 – solid baseline.
- gpt 4o-mini-transcribe – fast, efficient, improved accuracy.
- gpt 4o-transcribe – the most accurate option, ideal for complex audio.
Switching models is simple in the UI, and you can pick the best fit for your project. We're excited to hear how you’ll use these new capabilities—drop us feedback anytime!
