Together AI has successfully built the world's fastest speech-to-text stack by optimizing multiple stages of the process, resulting in record-breaking speeds and a new standard for this critical technology.
Together AI has successfully built the world's fastest speech-to-text stack. The company optimized multiple stages of the speech-to-text process to achieve this record-breaking speed. The first stage focused on reducing latency spikes caused by Python's garbage collector. The next major breakthrough came from optimizing the decoder loop using Conditional CUDA graphs. Streamlining the audio processing pipeline resulted in substantial speed gains through collapsing unnecessary process boundaries and using shared memory. The final piece of the puzzle was the implementation of evented I/O, which enabled seamless integration of streaming capabilities without sacrificing performance.
Together AI, a leading innovator in artificial intelligence, has successfully built the world's fastest speech-to-text stack, shattering previous records and redefining the boundaries of this complex technology. The achievement is a testament to the company's commitment to innovation and its ability to tackle even the most challenging problems.
In a recent blog post, Together AI revealed the inner workings of their groundbreaking approach, which involves optimizing multiple stages of the speech-to-text process. The first stage focuses on reducing latency spikes caused by Python's garbage collector (GC), which was previously stealing time from the request loop. By freezing the preallocated state during startup, the company was able to eliminate these spikes and improve overall performance.
The next major breakthrough came in the form of optimizing the decoder loop, which had become a bottleneck in the process. Together AI employed Conditional CUDA graphs to move this critical component onto the GPU, significantly reducing CPU overhead. This move enabled the system to sustain smoother traffic patterns and reduce latency spikes.
In addition to these technical advancements, the company also made significant strides in streamlining the audio processing pipeline. By collapsing unnecessary process boundaries and using shared memory, Together AI was able to eliminate redundant copies and serialization/deserialization passes, resulting in substantial speed gains.
The final piece of the puzzle fell into place with the implementation of evented I/O, which allowed for a seamless integration of streaming capabilities without sacrificing performance. This innovation enabled the system to handle large volumes of audio data with ease, making it an ideal solution for real-time applications.
Together AI's achievement is all the more remarkable considering the complexity of the speech-to-text process, which involves multiple stages and requires significant computational resources. By tackling each stage individually and pushing the boundaries of what is possible, the company has set a new standard for this critical technology.
In conclusion, Together AI's record-breaking speed in speech-to-text technology is a testament to its commitment to innovation and its ability to tackle even the most complex problems. As the company continues to push the boundaries of what is possible, we can expect significant advancements in this field and a further reduction in latency spikes.
