Hi miarayhan,
For real-time phone voice agents, the choice between GPT-4o and GPT-4.1 depends on the specific needs of your application.
- GPT-4o is specially designed for real-time applications like phone agents and includes features tailored for speech-to-speech models as described in OpenAI Realtime.
- GPT-4.1 models may offer improved performance or new features over previous versions, though they are generally more focused on better text processing capabilities and might provide more stable and precise outputs for voice synthesis and understanding, as detailed in the April 15, 2025 changelog.
If you're prioritizing real-time speech capabilities, you might lean towards GPT-4o. However, if your focus is on newer enhancements and improved text processing, GPT-4.1 might be the way to go.
Please do let us know if you need further assistance about this and we will gladly investigate further.
