Qwen3.6 27B vs Qwen3.6 35B A3B

Alibaba · China  |  Alibaba · China · Updated June 2026

Quick verdict

Both are Alibaba models. Qwen3.6 27B is the newer, generally stronger default; reach for Qwen3.6 35B A3B when a specific cost or latency profile matters more than the latest capabilities.

Qwen3.6 27B and Qwen3.6 35B A3B are both Alibaba models, so the real question is not which lab to trust but which tier fits your workload and budget. Qwen3.6 27B is a dense 27B multimodal model with its family's best coding score — it beats a 397B mixture-of-experts, but costs more per token. Qwen3.6 35B A3B is a sparse 35B mixture-of-experts running on 3B active parameters — strong agentic coding at near-3B cost on consumer hardware. Since both come from the same lab, the comparison below focuses on the tier-and-cost trade-offs that actually separate them.

Who wins what

The best open coding score in its family — 77.2% on SWE-Bench Verified, beating Alibaba's own 397B mixture-of-experts at a fifteenth of the size

Qwen3.6 27B

It scores 77.2% on SWE-Bench Verified against Qwen3.6 35B A3B's 73.4% — a 3.8-point edge on real repository work.

Dense, so quality per gigabyte of VRAM is high: it fits one consumer GPU when quantised

Qwen3.6 27B

Qwen3.6 35B A3B is comparatively weak here — loses to its smaller dense sibling Qwen3.6 27B on every coding benchmark, despite more total parameters

Far stronger agentic work than its sparse sibling (59.3 against 51.5 on Terminal-Bench 2.0)

Qwen3.6 27B

A dense 27B multimodal model with its family's best coding score — it beats a 397B mixture-of-experts, but costs more per token — and it leads SWE-Bench Verified 77.2% to 73.4%.

Extreme sparsity — only 3B of 35B parameters active per token, giving near-3B inference cost

Qwen3.6 35B A3B

Qwen3.6 27B is comparatively weak here — every parameter fires on every token, so it is slower and costlier per token than the sparse 35B

Runs at roughly 120 tokens per second on a single 24GB consumer GPU

Qwen3.6 35B A3B

Qwen3.6 27B is comparatively weak here — hosted output pricing is the harshest in its family, and provider input prices moved by roughly half in a single quarter

Apache 2.0 weights with a 256K native context, extensible to about 1M via YaRN

Qwen3.6 35B A3B

Qwen3.6 35B A3B lists apache 2.0 weights with a 256K native context, extensible to about 1M via YaRN among its strengths; Qwen3.6 27B does not.

Which should you pick?

Anyone whose priority is the best open coding score in its family — 77.2% on swe-bench verified, beating alibaba's own 397b mixture-of-experts at a fifteenth of the size

Qwen3.6 27B

It is specifically built for that.

Anyone whose priority is extreme sparsity — only 3b of 35b parameters active per token, giving near-3b inference cost

Qwen3.6 35B A3B

That is its strongest area.

Qwen3.6 27B: where it fits

A dense 27B multimodal model with its family's best coding score — it beats a 397B mixture-of-experts, but costs more per token. Released April 22, 2026 by Alibaba, it is built for the best open coding score in its family — 77.2% on SWE-Bench Verified, beating Alibaba's own 397B mixture-of-experts at a fifteenth of the size, dense, so quality per gigabyte of VRAM is high: it fits one consumer GPU when quantised, far stronger agentic work than its sparse sibling (59.3 against 51.5 on Terminal-Bench 2.0), and dense models fine-tune far more predictably than mixture-of-experts models do.

Its trade-offs are real: every parameter fires on every token, so it is slower and costlier per token than the sparse 35B, hosted output pricing is the harshest in its family, and provider input prices moved by roughly half in a single quarter, and its SWE-Bench score comes from Alibaba's internal scaffold rather than the standard public harness. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

Qwen3.6 35B A3B: where it fits

A sparse 35B mixture-of-experts running on 3B active parameters — strong agentic coding at near-3B cost on consumer hardware. Released April 16, 2026 by Alibaba, it is built for extreme sparsity — only 3B of 35B parameters active per token, giving near-3B inference cost, runs at roughly 120 tokens per second on a single 24GB consumer GPU, apache 2.0 weights with a 256K native context, extensible to about 1M via YaRN, and preserves its reasoning across turns, which cuts the overhead of agentic loops.

Its trade-offs: loses to its smaller dense sibling Qwen3.6 27B on every coding benchmark, despite more total parameters, its SWE-Bench score comes from Alibaba's internal scaffold rather than the standard public harness, and all 35B parameters must stay resident in VRAM even though only 3B compute per token. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

Because Qwen3.6 27B and Qwen3.6 35B A3B come from the same lab (Alibaba), they share the same training philosophy and ecosystem — the decision is purely tier vs. cost. Qwen3.6 27B is the more capable, more recent option; the other earns its place only when its price or latency profile fits a specific job better. Most teams should default to Qwen3.6 27B and drop down only with a concrete reason.
