Native audio input and output without requiring separate speech-to-text and text-to-speech pipeline
Very affordable at $0.6/$2.4 per 1M tokens compared to GPT-4o Audio at $2.5/$10 per 1M tokens
128K context window supports extended conversation histories for voice applications
Low-latency audio responses suitable for real-time conversational interfaces
Weaknesses
Significantly weaker reasoning and instruction-following than GPT-4o Audio or full GPT-4o
Not competitive with Claude Sonnet 4.6 or Gemini 3.1 Pro on complex text-only tasks
Audio quality and naturalness falls short of dedicated TTS solutions like ElevenLabs or OpenAI's own TTS-1-HD
