Main risks
  • A successor may be near β€” 45 months since release
  • At 2.5 kg portability is limited
  • Bluetooth 5.2 trails the newer revisions
The risk level is computed from the release date and verified weaknesses. The confidence score appears only once enough owner reports exist.
This box relies only on verified specs, the release date and editorial assessment; owner reports join them as they come in. We do not predict prices.

Which models run on this card?

Whether a model runs on your machine is decided first by the graphics card's memory: the model file has to fit in VRAM with room left for the context window and the runtime. The states below are computed from memory alone; software support (CUDA, ROCm, Vulkan) is a separate matter.

Largest model that runs comfortably: Qwen3.5 4B

  • Qwen3.5 0.8B1 GB packageComfortable
  • Qwen3.5 2B2.7 GB packageComfortable
  • Qwen3.5 4B3.4 GB packageComfortable
  • Qwen3.5 9B6.6 GB packageRuns
  • gpt-oss-20b14 GB package Β· the maker states a 16 GB memory minimumNot suitable
  • Qwen3.5 27B17 GB packageNot suitable
  • Qwen3.5 35B24 GB packageNot suitable
  • gpt-oss-120b65 GB package Β· the maker states a 80 GB memory minimumNot suitable
  • Qwen3.5 122B81 GB packageNot suitable
  • ComfortableRoom for the model file and a long context
  • RunsFits; the context window may need to stay short
  • LimitedNot enough memory; part of the model spills to system RAM and runs slowly
  • Not suitableNot a GPU-run model on this card

Rule: 1.5Γ— the requirement in memory is Comfortable, 1.15Γ— Runs, 0.6Γ— Limited; the requirement is the default package size, or the maker's stated minimum where there is one (a stated minimum counts as fitting at exactly that figure). Package sizes are the Ollama library's, minimums the maker's own statement; read on 2026-09-11. Sources: ollama.com/library/qwen3.5, ollama.com/library/gpt-oss, openai.com/index/introducing-gpt-oss
