OpenAI: GPT Audio Mini
GPT Audio Mini is OpenAI's lower-tier audio-capable model, accepting both text and audio as inputs and supporting tool use. It works with a 128,000-token context window and produces up to 16,384 completion tokens per response. It does not support reasoning modes, and structured output support is not confirmed. Pricing sits at $0.60 per million input tokens and $2.40 per million output tokens. For teams building voice-driven or audio-processing workflows on a tighter budget, this model's native audio input and tool support make it worth considering alongside pricier alternatives. The tradeoff is transparency: there is no independent benchmark coverage to evaluate its quality against competitors, so any shortlisting should be treated as tentative until you run task-specific evaluations of your own. Budget-conscious buyers get a potentially useful feature set, but go in knowing the performance profile is currently unproven.
