Meta paper: small AI models that read raw letters may beat token-based ones

A Meta paper, summarised on Reddit's r/LocalLLaMA, trained small models of about 1 billion parameters to read raw bytes, roughly one letter at a time, instead of tokens. They learned partly by copying a bigger model, Llama 3 8B. With little training the token models won easily. With more training the token models levelled off while the byte models kept improving, and needed about 6 times less text to reach the same level.

AMD says new software makes its MI355X AI chip write text up to 3.3x faster

AMD is open-sourcing tuned ways to run three AI models, Qwen3.8-27B, Qwen3.8-Flash-Next and GPT-OSS-120B, on its Instinct MI355X data-centre GPU. It combines several techniques: running a model's whole step as one long-lived GPU program, letting a small model guess tokens ahead, lower-precision numbers, and keeping data next to each of the chip's two dies. AMD reports about 1,100, 750 and 1,470 tokens per second for one request at a time, 1.9 to 3.3 times faster than its comparison setups.

Sony patent would show game sounds as on-screen cues for deaf players

A newly published Sony Interactive Entertainment patent application describes turning in-game sounds into visual cues. The system would sort each sound by its purpose, such as building tension or warning of danger, and show an icon, shape or word like "Roar!". Lights around the screen or the DualSense controller's touchpad could show where a sound comes from. The filing says older games could get cues without changes to their code.

Brazilian court orders Meta not to interfere in the presidential runoff

Bloomberg reports that Meta has become a target in the closing stretch of Brazil's presidential election, whose runoff is on October 25. President Lula da Silva alleges that Meta restricts his content, and a judge at Brazil's top electoral court ordered the company to treat both candidates equally, with a fine of 500,000 reais per day if it fails to comply, AP and Reuters report. Folha de S.Paulo reported internal messages in which Meta staff acknowledged Lula's Instagram accounts were hit by restrictions. Meta says the problems were glitches and that any suggestion it favours one side is false.
