    The only scenario is if you have enough work to do batch inference. Using a tiny fraction of GPU capacity to decode a single request at a time just doesn't make sense, as you say.

    It's roughly equal on price and intelligence as GLM 5.2 while being ~8x faster.

    It tops benchmarks because it uses them in its training data. https://x.com/eliebakouch/status/2077425801633427919

    This just isn't true. On balance, data centers are turning out to be more like the "anchor tenant" of the power grid, financing improvements for everyone. Overview article with lin…

    FWIW -- Granite r2 small is a 30M model, still small enough to run on CPU, and a good baseline for fine tunes.

    Yes, disappointing given that Chronicle actually does have legit expertise here. (Chronicle Map is not very well-known even in the Java space but it's by far the best larger-than-m…

    That's a reasonable option, just be aware that you get about 1/3 as much memory bandwidth with the M5 Pro, or 2/3 with the M5 Max [now you're at $4100 for the lowest-end]. So both …

    Because you need kv proportional to context length during inference of a single token to avoid quadratic recomputation. So compressing the kv lets you handle longer contexts in the…
