    Show HN: Visualizing Tiny LLMs from OpenAI's Parameter Golf

    The two from parameter golf (one I trained, one was the baseline) are just 16MB each! They produce barely plausible English

    Self Hosted object storage looks neat! For this project, where you have 120GB of customer data, and thirty requests a second for ~8k objects (0.25MB/s object reads), you’d seem to …

    I'm using Sonnet with 1M Context Window at work, just stuffing everything in a window (it works fine for now), and I'm hoping to investigate Recursive Language Models with DSPy whe…

    This is super interesting! Apache Arrow is trying to do something similar, using Flatbuffer to serialize with zero-copy and zero-parse semantics, and an index structure built on to…

    My threshold for “does not need to be smaller” is “can this run on a Raspberry Pi”. This is a helpful benchmark for maximum likely useful optimization. A Pi has 4 cores and 16GB of…

    Show HN: DSPy on a Pi: Cheap Prompt Optimization with GEPA and Qwen3

    GEPA was very efficient at optimizing my LLM task description, and DSPy was effective at turning a soup of a prompt into something programmable with inputs and outputs

    Curious about comparisons with Apache Arrow, which uses flatbuffers to avoid memory copying during deserialization, which is well supported by the Pandas ecosystem, and which allow…

    fast.ai (some of the authors of this) was transformative for me, and the community was super nice. Cannot recommend looking into this highly enough.

    Interesting! Text files in git can work for small sizes, like your 100MB. That is what's known in FAISS as a "flat" index, just one thing after another. And obviously you can query…

    That’s wild that with a KV cache and compilation on the Mac CPU you are faster than on an A100 GPU.

    Also: this SSO tax is deceptively framed. Many of these services allow one to sign in through, for example, Google, which can count as a single sign on, and many organizations have…

    This is evocative of “cramming”, a paper from a few years ago, where the author tried to find the best model they could train for a day on a modern laptop: https://arxiv.org/abs/22…
