Claude Haiku 4.5· Qwen3.6 Plus

Quick Verdict

Pick Qwen3.6 Plus if you want the stronger benchmark profile. Claude Haiku 4.5 only becomes the better choice if reasoning is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Qwen3.6 Plus is clearly ahead on the aggregate, 69 to 63. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Qwen3.6 Plus's sharpest advantage is in coding, where it averages 64.9 against 48.5. The single biggest benchmark swing on the page is GPQA, 67% to 90.4%. Claude Haiku 4.5 does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

Claude Haiku 4.5 is also the more expensive model on tokens at $0.80 input / $4.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.6 Plus. That is roughly Infinityx on output cost alone. Qwen3.6 Plus is the reasoning model in the pair, while Claude Haiku 4.5 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Qwen3.6 Plus gives you the larger context window at 1M, compared with 200K for Claude Haiku 4.5.

Decision framing

BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.

Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
