OpenAI: GPT-4o Audio
Analysis Summary
GPT-4o Audio extends OpenAI's GPT-4o line with native audio input and output, useful for voice-based applications, but its reasoning and coding benchmarks are weak compared to current-generation models.
Businesses building voice assistants or audio transcription-plus-response workflows may find value in its multimodal audio handling, but it should not be relied on for complex analysis, coding, or agentic tasks.
Pricing is high relative to its measured capability, so it is best reserved for audio-specific use cases rather than general-purpose deployment.
