    The OpenAI model that broke out of its sandbox and hacked HuggingFace was running without guardrails. To quote the OpenAI post[1]: These deployment safeguards were intentionally no…

    This post does not mention safety at all. What's to stop bad actors from fine tuning open weights to run fully automated genius-level scams personally targeting basically everybody…

    > I don't see it happening. Isn't it already happening with Cerebras? It's mentioned at the end of OpenAI's GPT 5.6 announcement: " We're also launching GPT‑5.6 Sol on Cerebras at …

    The UX problem is elsewhere I think. Many users probably don't realize that the agent's context window is limited, and that clever compaction is happening regularly to make it seem…

    Once you realize how much more efficient solar panels are (compared to plants) at capturing energy from the sun, the next logical question is: could it make sense to synthesize foo…

    You don't even need to double the tokens. Tokens are mapped to vectors right at the input of the LLM, so one of the numbers in that vector could be reserved to represent something …

    The coal price has a tendency to spike during an energy crisis. The market is more volatile than crude oil. For example, check what happened in 2022. https://tradingeconomics.com/c…

    It seems the S&P 500 indices only take the free-float shares into account when calculating weights: S&P DJI’s market cap-weighted indices are float-adjusted – the number of shares …

    I can play a pure sine wave tone with a tone generator app, and dial the frequency up until it precisely matches my tinnitus. I originally did this just to determine that frequency…
