Qwen3.5 27B DFlash — 2.1B params (z-lab).
At $0.12/1M tokens, the cheapest API for Qwen3.5 27B DFlash stays cheaper than a used RTX 3090 at any daily volume — electricity alone costs more per token than the API does.
Local is never $0 — every figure here includes electricity and hardware amortization. Speeds come from published 7-8B Q4 benchmarks (your model, quant, and context will differ); break-even volumes are rounded to 2 significant figures.
| Parameters | 2.1B |

| Context window | 262.1K tokens |
| Recommended quant | Q4_K_M |
| VRAM requirement | ~3 GB (at Q4_K_M, 16.4K context) |

Three ways: $0 on your own machine if you have about 3 GB of VRAM (at Q4_K_M); a rented GPU from $0.06/hr (NVIDIA RTX 3060 12GB at the direct Vast.ai price); or about $0.12 per 1M blended tokens via your own API key (a rough estimate for this size). Spanvero adds $0 markup on every path.
Yes — Qwen3.5 27B DFlash runs locally for $0 in compute if your GPU or Apple Silicon Mac has about 3 GB of VRAM/unified memory (at Q4_K_M with 16.4K context). Point LM Studio, Ollama, or llama.cpp at it; after the download it runs offline and free.
Any GPU or Apple Silicon Mac with about 3 GB of VRAM/unified memory handles Qwen3.5 27B DFlash at Q4_K_M. Of the consumer hardware Spanvero tracks, the smallest that fits is a used NVIDIA RTX 3070 8GB.
