OpenAI擴大測試語音合成AI模型,用15秒樣本即可模擬真人聲音

OpenAI上週公佈 語音生成AI模型Voice Engine 初步成果,號稱只要上傳15秒的人聲樣本,及輸入文字稿,就能產生極似原説話者聲音的自然語音。

OpenAI於2022年開始開發Voice Engine模型。這個模型已用於其OpenAI的 語音合成(TTS)API 及ChatGPT去年秋天上

Llamafile 0.7 Brings AVX-512 Support: 10x Faster Prompt Eval Times For AMD Zen 4

A new release of Llamafile is available this Easter Sunday from the Mozilla Ocho group. Llamafile is a means of distributing and running large language models (LLMs) from a single file, making LLMs much easier to distribute and use by developers and end-users. Llamafile remains one of the more interesting non-browser projects out of Mozilla in recent times that so far has a bright future.

Llamafile makes dealing with large language models much more convenient and easier to deploy by leveraging Llama.cpp and making it easy to deliver

OpenAI reveals Voice Engine, but won’t yet publicly release the risky AI voice-cloning technology

SAN FRANCISCO (AP) — ChatGPT-maker OpenAI is getting into the voice assistant business and showing off new technology that can clone a person’s voice, but says it won’t yet release it publicly due to safety concerns.

The artificial intelligence company unveiled its new Voice Engine technology Friday, just over a week after filing a trademark application for the name. The company claims that it can recreate a person’s voice with just 15 seconds of recording of that person talking.

OpenAI says it plans to

Here’s how NVIDIA is supercharging GenAI speed with TensorRT running locally

In the last couple of years, AI has exploded in popularity, with chatbots and image generators driving much of that surge. These tools are trained extensively on vast datasets called Large Language Models (LLMs), which they draw from to generate the results we see. However, getting those results quickly relies on some serious computing power. Over 100 million users are already putting powerful NVIDIA hardware to task running AI models. That’s because NVIDIA offers hardware that excels at that process

Linux Foundation Launches Valkey As A Redis Fork

Given the recent change by Redis to adopt dual source-available licensing for all their releases moving forward (Redis Source Available License v2 and Server Side Public License v1), the Linux Foundation announced today their fork of Redis.

The Linux Foundation went public today with their intent to fork Valkey as an open-source alternative to the Redis in-memory store. Due to the Redis licensing changes, Valkey is forking from Redis 7.2.4 and will maintain a BSD 3-clause license.

Claude 3 Opus模型於Chatbot Arena上擊敗GPT-4 Turbo

就在這幾天,專門盲測大型語言模型(LLM)能力的 LMSYS Chatbot Arena排行榜 出現了變化,由Anthropic所打造的Claude 3 Opus模型擠下了OpenAI的GPT-4,成為該排行榜上等級最高的LLM。

LMSYS Chatbot Arena是由研究組織 Large Model Systems Organization在去年5月所發表 ,為一採用Elo評分系統的

GPT-4 loses its position as "best" LLM to Claude-3 in LMSYS benchmark

Serving tech enthusiasts for over 25 years.
TechSpot means tech analysis and advice you can trust .

In context: It seems as if everyone who is anyone has thrown their hats and their money into developing large language models. This AI explosion prompted a need to benchmark them for comparison. So, UC Berkley, UC San Diego, and Carnegie Mellon University researchers formed the Large Language Systems Organization (LMSYS Org or just LMSYS).

Grading large language models and the chatbots that use them is difficult. Other than counting instances

(PR) NVIDIA Hopper Leaps Ahead in Generative AI at MLPerf

It's official: NVIDIA delivered the world's fastest platform in industry-standard tests for inference on generative AI. In the latest MLPerf benchmarks, NVIDIA TensorRT-LLM—software that speeds and simplifies the complex job of inference on large language models—boosted the performance of NVIDIA Hopperarchitecture GPUs on the GPT-J LLM nearly 3x over their results just six months ago. The dramatic speedup demonstrates the power of NVIDIA's full-stack platform of chips, systems and software to handle the demanding requirements

LLVM BOLT Optimizations Net ~6% Improvement For GNOME's Pango

BOLT that was upstreamed into LLVM in 2022 by Facebook/Meta allows for optimizing the layout of binaries as a post-linking step to yield increased performance. BOLT like Profile Guided Optimizations (PGO) first requires the profiling step to generate perf recordings to feedback in for the optimization process, but the gains can be significant.

BOLT can yield very nice performance gains as shown across various workloads thanks to reorganizing the layout of libraries/binaries. The latest praise for LLVM's BOLT is by GNOME developer Christian
