| Summary | Fish Audio S1 text-to-speech. Billed per UTF-8 byte of input text. | Qwen3-ASR 0.6B speech-to-text. Billed per second of audio. | GPT-6 Sol Pro uses the same underlying model as GPT-6 Sol, but runs with reasoning.mode set to pro for higher-quality responses on complex and demanding tasks. Optimized for deeper reasoning, greater accuracy, and more reliable multi-step execution, it is particularly well suited for agentic coding, long-horizon software engineering, professional analysis, and complex automated workflows where solution quality takes priority over latency and cost. | Perceptron Mk1.5 chat model that accepts audio input. Audio and text input are billed per token. |
