Can I run Qwen 3.5 35B-A3B?
Qwen 3.5 35B-A3B by Alibaba needs around 32 GB of RAM at the recommended 4-bit quantization (21.2 GB download). Your hardware is checked below — instantly, nothing leaves your browser. Expect roughly ~192 tok/s on a Apple M-series Max.

Real-world notes
Qwen 3.5 35B-A3B is a mixture-of-experts model with a useful trick at its core: of its 35B total parameters, only about 3B are active per token. So it generates at the speed of a tiny model while drawing on the knowledge of a big one. The catch is memory. You still hold the whole model in RAM, so plan around the full footprint, not the active slice. At 4-bit it lands near 21 GB, and you want at least 32 GB of system memory. A 12 GB RTX 3060 will not fit it, so realistically this is a 24 GB GPU or high-memory Apple Silicon machine.
Once it fits, the MoE design pays off and it feels quick for its weight class. On an RTX 4090 you can see around 471 tokens per second, and on an Apple M Max roughly 192, both fast enough that the answer outpaces your reading. CPU on DDR5 manages about 28 tokens per second, slow but usable for batch work. It handles chat, reasoning, coding, and vision, with a generous 256K context window. Treat that ceiling carefully though: at 128K context the total memory footprint climbs to about 53.8 GB, so long-context sessions need a genuinely large machine, not just enough to load the weights.
Against Command R 35B, a same-size dense model worth comparing, the real difference is the MoE architecture rather than the parameter count: same nominal size, but Qwen tends to run far faster per token because only 3B are active. That speed-to-capability ratio is its standout trait, getting near-instant generation out of a model with 35B worth of knowledge, plus the multimodal vision support. The smaller Qwen 3 0.6B and 1.7B are the picks if you are memory-constrained and only need basic chat. Licensing is the easy part: Apache 2.0 means you can use it freely, including commercially and in production, with no provider-specific terms to read.

Memory needed by context length
| Context | KV cache (est.) | Total memory (Q4) |
|---|---|---|
| 4K tokens | ~1.0 GB | ~22.2 GB |
| 8K tokens | ~2.0 GB | ~23.2 GB |
| 32K tokens | ~8.1 GB | ~29.3 GB |
| 128K tokens | ~32.6 GB | ~53.8 GB |
The KV cache grows with context length — a model that fits at 4K can run out of memory at 32K. Estimates assume an FP16 cache with grouped-query attention; actual usage varies by runtime.
Estimated speed by hardware
| Hardware | Bandwidth | ~Speed |
|---|---|---|
| NVIDIA RTX 3060 12GB | 360 GB/s | Won't fit in VRAM |
| NVIDIA RTX 4090 24GB | 1008 GB/s | ~471 tok/s |
| Apple M-series (base) | 100 GB/s | ~47 tok/s |
| Apple M-series Pro | 270 GB/s | ~126 tok/s |
| Apple M-series Max | 410 GB/s | ~192 tok/s |
| CPU only (dual-channel DDR5) | 60 GB/s | ~28 tok/s |
Token generation is memory-bandwidth bound: tok/s ≈ bandwidth × 0.85 ÷ model size at Q4. Real-world numbers vary by runtime and context length.
