Unverified50% confidenceFactExact time
When the TTS engine runs alone, generating 1 second of audio takes about 0.6 seconds (RTF about 0.6), but after sharing the GPU with the LLM, first-sentence synthesis time balloons to about 1.5 times its own length, whereas when the LLM is idle it takes only about 1.0 times.

UnverifiedOn an RTX 4060 Laptop (8GB VRAM), having the LLM actively pause and wait for TTS to synthesize sentence by sentence can eliminate audio playback stutter, at the cost of greatly extending the LLM's overall generation time (in testing, from about 12 seconds to about 54 seconds).76% similarUnverifiedOn the same T4, vLLM 0.27.1 took only 5.8 seconds in total for 8 requests after ready; vLLM's startup overhead was about 165 of 171 billed seconds.75% similarUnverifiedRTF (Real-Time Factor) is defined as the ratio of the computation time required to generate audio to the duration of that audio, with a 5x real-time speed corresponding to an RTF of 0.2.73% similarUnverifiedIn the email classification task, TEF 1 (4B) took 1.273 seconds to run through all samples, while GPT needed 2.568 seconds; in the sponsorship inquiry scoring task, TEF 1 took 1.09 seconds while GPT took about 2.58 seconds.71% similarUnverified一个需要20次LLM调用、每次生成200个Token的Agent任务，在30 TPS下需要约133秒完成，在300 TPS下仅需13秒71% similar
