What is Qwen3 30B-A3B?
Qwen3 30B-A3B is a mixture-of-experts with 30B total parameters but only about 3B active
per token — near-32B quality at a fraction of the compute, and very fast locally. Apache 2.0,
128K context, roughly 18 GB of VRAM at 4-bit on an RTX 4090 24GB.
The speed is the reason to pick it. Because only ~3B parameters are active on each token,
generation runs several times faster than a dense 32B on the same card, while memory use is
only modestly higher. That combination matters specifically for local interactive work —
coding assistants, chat interfaces, anything where you are watching tokens appear — where a
dense 32B on consumer hardware is often just slow enough to be irritating. The trade is that
you pay for 30B of memory to get 3B of speed, so on a 24 GB card the dense Qwen3 32B remains
the better choice if raw quality per gigabyte matters more than latency. Choose 30B-A3B when
responsiveness is the feature.

What Qwen3 30B-A3B costs per month
Tatsächliche monatliche Ausgaben bei einem 4:1-Input-zu-Output-Mix – dem Verhältnis, das typische Chat- oder RAG-Arbeitslasten tatsächlich erzeugen.
| Workload | Tokens/Monat | Kosten pro Monat |

Selbst hosten oder die API nutzen?
Qwen3 30B-A3B is open-weight, so you can run it yourself. It needs ~18 GB of VRAM at 4-bit (RTX 4090 24GB (Q4) — fast, 3B active). Self-hosting only beats the API once your volume is high enough to keep that hardware busy — the Selbsthosting vs. API-Rechner berechnet den Break-even-Punkt für Ihr Token-Volumen.
Häufig gestellte Fragen
How much does Qwen3 30B-A3B cost per 1M tokens?
Qwen3 30B-A3B costs $0.120 per 1M input tokens and $0.500 per 1M output tokens. At a typical 4:1 input-to-output mix that blends to about $0.196 per 1M tokens.
How much does Qwen3 30B-A3B cost per month?
A small-team workload of 20M input and 5M output tokens a month costs about $4.90 on Qwen3 30B-A3B. A side project (1M in / 0.25M out) costs roughly $0.25.
What is a cheaper alternative to Qwen3 30B-A3B?
Mistral 7B is the strongest cheaper option in our database at $0.0220 per 1M blended — about 89% less than Qwen3 30B-A3B. It is also open-weight, so self-hosting is an option.
Can I run Qwen3 30B-A3B locally?
Yes. Qwen3 30B-A3B is open-weight and needs about ~18 GB of VRAM at 4-bit quantisation (RTX 4090 24GB (Q4) — fast, 3B active).
Why does Qwen3 30B-A3B charge more for output than input?
Output tokens are generated one at a time and cannot be batched the way a prompt can, so they cost the provider more to serve. Qwen3 30B-A3B charges 4.2× more for output, which is why prompt-heavy workloads are far cheaper to run than generation-heavy ones.
