🛠 Fish Audio S2.1 Pro for Free
Fish Audio has released its flagship S2.1 Pro model, which supports 83 languages. Until the end of July 2026, developers can access the API for free via the s2.1-pro-free model. The update has reduced latency (TTFA) to 70–90 ms and doubled throughput thanks to fish-scales-ops kernels for NVIDIA Hopper and Blackwell.
🌍 The use of FP8 GEMM and FlashAttention libraries allows for efficient scaling of high-quality TTS on modern GPUs, lowering the barrier to entry for creating real-time voice agents.
👤 You can free-test one of the best speech synthesis models with extremely low latency to create smart assistants or voice content.
