Decision reading

GPT-5.5 has the higher public score, 73.27 versus 61.49, and the 90% score intervals do not overlap.

17 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

17 Shared

Shared results: 17
GPT-5.5 only: 21
Qwen3.6 Plus only: 31
Like-for-like categories: 3 / 8

2 categories rest on Estimated evidence or different evidence sets. Those rows remain visible for coverage context but do not name a winner.

Category results, on a stated basis

Each row shows the public-lane category score for both models: the BenchAlign lane for agentic, coding, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, and knowledge denominators (BenchAlign) differ from the provisional-lane categories. Unranked scores sit on the lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

If you already use one of these models

Deployment change: The models list different providers, so authentication, endpoint behavior, limits, and feature support may change.
Quality signal: GPT-5.5 has the higher public score, 73.27 versus 61.49, and the 90% score intervals do not overlap.
Workload cost: A complete comparable API-rate estimate is not available for both models.
Context tradeoff: Both models list 1M.

Run the same representative tasks against both endpoints before changing production traffic.

Which is better, GPT-5.5 or Qwen3.6 Plus?

GPT-5.5 has the higher public score, 73.27 versus 61.49, and the 90% score intervals do not overlap. That is the clearest overall quality signal in the current public data.

Which is better for coding, GPT-5.5 or Qwen3.6 Plus?

GPT-5.5 leads the public coding lane, 67.7 to 47, with Supported evidence for both models and non-overlapping 90% intervals.

Which is better for agentic tasks, GPT-5.5 or Qwen3.6 Plus?

GPT-5.5 leads the public agentic tasks lane, 63.9 to 36.4, with Supported evidence for both models and non-overlapping 90% intervals.

Which costs less, GPT-5.5 or Qwen3.6 Plus?

Both models do not have comparable published API token rates, so this page does not name a universal price winner.

Which has the larger context window, GPT-5.5 or Qwen3.6 Plus?

Both models list the same context window, 1M.
