Which quant should I pick?

Pick your GPU and a model, and we'll rank its quants from highest to lowest quality — with the fit verdict, size, an estimated speed, and a plain-English note on what you give up at each step down. No account needed.

1 · Your GPU

  • No matching GPU in the list — you can type the model manually.

Search for your card above (Apple Silicon routes to unified memory automatically). Without a GPU we'll still show sizes and the quality guidance below.

Used to judge partial CPU offload when a quant overflows VRAM.

2 · Model & context

Lower precision shrinks the KV cache (fits more context).

  1. safetensors · BF16 Community default
    3.59 GB

    Full 16-bit (bfloat16) weights: no quantization loss, but about twice an 8-bit quant's size.

    Note: BF16 source weights (official Qwen3-TTS-12Hz-1.7B-Base) — reference TTS artifact. GGUF community-only; safetensors is the universal format (Transformers/vLLM). Bundles speech_tokenizer codec (+682MB) + tokenizer/config.

Verdicts and sizes match this model's page exactly. Speeds are roofline estimates (a range, not a promise). Quality notes reflect community experience, not measured benchmarks.
