Lightning is the latest text-to-speech model developed by smallest.ai, breaking barriers in performance and size in multimodal AI with its ultra-fast processing speed and compact footprint. The model supports various accents in languages like English and Hindi, with rapid plans to expand to more languages. Lightning's non-autoregressive architecture allows the simultaneous synthesis of entire audio clips, unlike traditional autoregressive models that require sequential audio generation. Key advantages of Lightning include high generation speed, small model size, multilingual support, and quick adaptation to new data. Background information indicates that the launch of Lightning aims to significantly reduce latency and costs for voicebot companies by streamlining their architectures. Pricing for Lightning starts at $0.04 per minute, offering customized pricing plans for enterprise customers using over 100,000 minutes monthly.
