Qwen3.5

From the documents of veizik-qwen-cuda-1.1.3-linux-x86_64.vzpack (release v1.1.3).

• Five language models in one package: Qwen3.5-0.8B, Qwen3.5-2B, Qwen3.5-4B, Qwen3.5-9B and Qwen3.6-35B-A3B (mixture of experts, about 3B active per token). Every model does completion and chat.
• veizik run <model> "prompt" generates once and writes the text to gen.txt in the folder you pass with --out. Greedy decoding is the default and gives the same output every time. --tokens N (or --max-tokens N) sets the length, and --ignore-eos emits exactly N tokens. Sampling is opt-in with --seed, --temperature, --top-p and --top-k, and is experimental.
• Run options are one vocabulary across engines, and the command passes on only the ones an engine accepts. For Qwen: --seed, --steps, --mode, --temperature, --top-p, --top-k, --tokens, --max-tokens, and on Qwen3.6-35B-A3B also --image, --video, --image-max-pixels, --video-max-pixels and --video-fps. Any other option is refused with <flag> does not apply to this model. Every run also takes --out, --name, --prompt-file, --resume, --resume-from and --checkpoint-every.
• veizik chat <model> holds an interactive conversation, using the package's signed model catalogue. It needs veizik activate once per device and the model's weights (--weights DIR or VZ_WEIGHTS).
• veizik serve <model> is a local OpenAI-compatible HTTP server on 127.0.0.1 only: POST /v1/chat/completions (with streaming), POST /v1/completions, GET /v1/models, and health endpoints. Turn on an API key with --require-auth --keyfile FILE. Each request may use up to 4,096 tokens, prompt plus output. It needs veizik activate once per device and the model's weights (--weights DIR or VZ_WEIGHTS).
• veizik doctor checks the install root, the activation service and the CLI binary; veizik status shows the device's activation and plan; veizik version shows the version and backend.
• Five modes: quality (most memory, slowest), balanced (the default), fast, ultrafast (the fastest) and low-memory (smallest footprint, lowest quality).
• GPU code for text on sm_80, sm_86, sm_89, sm_90a, sm_100a and sm_120a. One GPU runs one model.
• Activation is once per device, and one approval covers every model: veizik activate in a browser, or veizik activate --key KEY --password-stdin without one. veizik devices lists the devices on your licence and switches them on or off, and veizik device-id prints this machine's id.
• veizik install downloads the package from its public GitHub release and refuses it unless its SHA-256 matches the published release; the engine checks its own files at every start, and a changed, added or missing file stops the run with exit code 4.

“Verified” means this family ran end to end on that exact device, on a published build. Architecture membership never upgrades a device to verified.

Each table shows the GPUs a model was measured on and one figure per measure: the default mode and the most common workload. Hover a figure for its build, date, runs and range; open All figures for every mode and workload. A figure marked earlier build is our own measurement of an earlier build of the engine, shown because the computation it exercises did not change in substance; it is replaced when the package you download is measured on that GPU. A figure whose build reads carried, measured on another build was measured on that earlier build of the same package and stands for the package named, because the change between the two did not alter the computation.
