Why people recommend it

Each mark is one comment

  • Strong at coding specifically

    “things like Laguna S2.1 NVFP4 gets really close of almost being there, when it comes to coding specifically”

    Comment from 31 Jul 2026 in “The Session You Cannot take with you”

    “Really impressive signal that this 128B model can beat DeepSeek V4 (1.6T) on most coding benchmarks!”

    Comment from 21 Jul 2026 in “Laguna S 2.1”

    “Works amazingly for coding, pretty bad for pretty much anything else.”

    Comment from 8 Aug 2026 in “U.S. Department of Energy Launches the Genesis Open Models Initiative”
  • Fast for its size

    “This is really a sweet spot imo on this machine between maximizing ram use and still having decent speed due to the expert size.”

    Comment from 22 Jul 2026 in “Laguna S 2.1”

    “it positively flies on an m5 max - the 60tok/s decode / ~500tok/s prefill is real.”

    Comment from 23 Jul 2026 in “Laguna S 2.1”

    “seems to be on par (or better) than DeepSeek v4, is only 110B, and it's faster”

    Comment from 8 Aug 2026 in “DeepSeek V4 Flash 0731”
  • Cheap, rivals DeepSeek V4 Flash

    “it seems to be a bit behind Meta Muse Spark 1.1 performance at approximately the Deepseek v4 Flash price point”

    Comment from 22 Jul 2026 in “Laguna S 2.1”

    “I am SO impressed by this model! It's cheap as deepseek v4 flash, better than minimax m3 I would say”

    Comment from 30 Jul 2026 in “Laguna S 2.1”

    “I think this is probably also stupider than laguna s 2.1 which can also be very cheap to serve”

    Comment from 23 Sep 2026 in “Mercury 2.5 LLM hits 770 tokens per second”
  • Size fits home hardware

    “This is really a sweet spot imo on this machine between maximizing ram use and still having decent speed due to the expert size.”

What people warn about

Each mark is one comment

  • Weak outside coding tasks

    “Laguna and Muse Glimmer failed hard on it, though they're useful for other tasks.”

    Comment from 15 Aug 2026 in “Qwen 3.8 27B is out: open weights, best local dense model yet”

    “Works amazingly for coding, pretty bad for pretty much anything else.”

    Comment from 8 Aug 2026 in “U.S. Department of Energy Launches the Genesis Open Models Initiative”

    “Laguna and Muse Glimmer failed hard on it, though they're useful for other tasks”

    Comment from 14 Aug 2026 in “Qwen 3.8 27B is out: open weights, best local dense model yet”
  • Buggy releases and quantizations

    “Laguna provided quants have some issues and they are reworking/updating them.”

    Comment from 23 Jul 2026 in “Startup founders urge Trump not to shut off Chinese open weight AI”

    “Initially there were serious bugs, also about the templates”

    Comment from 8 Aug 2026 in “U.S. Department of Energy Launches the Genesis Open Models Initiative”

    “There was an obvious problem in the original release, they re issued it after like a week with the reasoning looping supposedly fixed.”

    Comment from 8 Aug 2026 in “U.S. Department of Energy Launches the Genesis Open Models Initiative”
  • Memory hungry, slows at long context

    “very memory hungry and PP speed drops off a cliff around 200k context”

    Comment from 26 Jul 2026 in “Laguna S 2.1”

    “their latest updates means it doesn't quite fit a GB10 128GB anymore at full context which is a shame”

    Comment from 21 Sep 2026 in “MiMo v2.6”
  • Unreliable as an agent

    “pretty bad as an agent - not proactive, would frequently stubbornly argue things that weren't true”

    Comment from 8 Aug 2026 in “U.S. Department of Energy Launches the Genesis Open Models Initiative”

    “very comfortable for chatting, but still not usable for interactive agentic coding”

    Comment from 23 Jul 2026 in “Laguna S 2.1”

    “the outputs so far aren't impressive, and it gets stuck and perseverates”

    Comment from 29 Jul 2026 in “Show HN: Open-source engine running Gemma 4 26B in 2 GB RAM on any M-series Mac”
