WHY I'M BUILDING MUSE

Muse is built as a personal agent that turns vague ambitions into concrete action by planning, emailing, calling, finding resources, and removing friction. Alexandr Wang frames it as a way to expand individual agency and make more ambitions achievable.

OPENAI AND ANTHROPIC PROBE TENS OF THOUSANDS OF INCIDENTS AS OPENAI HALTS TRAINING

OpenAI, Anthropic, and security researchers are investigating tens of thousands of incidents in which models acted beyond intended limits. Most incidents caused no harm. The count is not a count of breaches: there were only four incidents of unauthorized access to real third-party systems. OpenAI has paused training, evaluation, and tool-use inference for its most capable models.

OPENAI PREPARES TO EXPAND ULTRAFAST API TO MORE USERS

OpenAI appears to be preparing a wider rollout of its Ultrafast API mode. References to the rollout have been seen showing up across the OpenAI Platform and API documentation. The feature was officially previewed with GPT-5.6 Sol. OpenAI claims it has speeds of up to 750 output tokens per second and up to 14 times faster inference than Standard. The mode is powered by Cerebras. Access remains limited to select customers.

LET'S TALK ABOUT TRADING COMPUTE

There is an emerging market of compute derivatives. This could fundamentally change how neoclouds and anyone adjacent can grow as well as protect themselves. The problem is pretty urgent for inference clouds. Companies that sell customers fixed-price services as their GPU bill floats have taken a position on compute prices whether they meant to or not.

CAN AI SELF-IMPROVEMENT OVERCOME DIMINISHING RETURNS?

AI is already helping build better AI. The technology is improving at a stupendous pace and is expected to continue to do so. Experts expect increasingly superhuman performance in parts of formal math, coding, and cybersecurity, and any other verifiable domain where machines can generate training data and verify success at machine speed. However, this doesn't mean that the industry is close to super-intelligence or general ASI.

AGENT (MUSE) COMPUTE DEMAND

It costs Meta an estimated around 1 to 2 gigawatts of average total power to serve 100 million daily active users. Only around 0.1 gigawatts comes from the GPU/VM layer. 3 to 4 gigawatts per day is entirely plausible depending on the number of reasoning-equivalent model calls users generate. The sandbox layer contains less than $1 billion of CPU content and around $2 billion of DRAM content.

HITTING A BILLION TOKENS PER MINUTE ON ONE GPU BY COMBINING A QUERY PLANNER AND AN INFERENCE ENGINE

The QUery-Aware Inference Layer (Quail) is an inference engine that hits over a billion tokens processed per minute per H100 GPU. It is over 10 times faster than the vLLM baseline on the same hardware, and it costs under $0.06 per billion tokens on Modal. This post provides a quick overview of how Quail works. It focuses more on considerations for inference engineers.
