What people warn about

Each mark is one comment

  • Trails Qwen models on benchmarks

    “The absence of any comparison to Qwen3.8 Flash, another MoE model with a small-ish (6B) number of active parameters, is pretty striking.”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”

    “Qwen3.8 27B beats Kolibri 79.9 vs 70.8 in German in Kolibri's harness on Kolibri's benchmark.”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”

    “Qwen 3.8 27B beats Kolibri on nearly every single benchmark.”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”
  • Needs fp16, too big for consumer hardware

    “they only have fp16 which won't fit on my Mac”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”

    “Interesting they recommended high end software without considering quant 4 or 8”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”
  • Overthinks and wastes tokens

    “spends way too many tokens on overthinking stuff”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”

    “It can't seem to think things through by itself and then make more tool calls to fetch more information.”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”
  • Sovereignty claims undermined by backers

    “With Schwarz, Cohere, SAP, NVIDIA and the like as backers society can’t have souvereignty in any meaningful way.”

    Comment from 3 Oct 2026 in “Kolibri: A Sovereign Open-Weight Model”

    “I think it’s a safe assumption that they’re leaning into “sovereign” because performance is bad.”
