MODERN LLMS HAVE TINY GPTS HIDDEN INSIDE THEM

It's likely that modern LLMs have tiny self-models of LLMs inside of them that allow them to better predict the next token generated by LLMs. Models approximating LLMs within themselves would open up all sorts of metacognitive abilities. It would open doors for a self-model within LLMs similar to a model humans have about themselves they call a 'self'.

700 TPS ON KIMI K3: A CASE FOR TPU MEGAKERNELS

inferact/tpu-megakernels is a collection of megakernels for TPU v7. Its Kimi K3 implementation delivers over 700 tokens per second with speculative decoding. Without speculative decoding, its megakernels for K3 and Qwen 3.8 27B deliver roughly 1.4 to 2x the decode throughput of the GB200 baseline at batch sizes 1 through 8.

A lot of the infrastructure neoclouds have is built around flash, so for storage that doesn't need flash, they often point customers to hyperscaler object storage solutions instead. The more data you have stored somewhere, the harder it becomes to leave. While the neocloud keeps getting paid for GPU, the hyperscaler quietly takes over the broader account.
