Grok Code Fast 1 vs Qwen3.6-27B
Updated September 4, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.
Decision reading
Qwen3.6-27B has the higher public score, 52.73 versus 37.21, and the 90% score intervals do not overlap.
1 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

Not enough matched evidence
Grok Code Fast 1 is scored on Estimated evidence for coding, so the reading is directional rather than like-for-like.
Confidence: limited
Agentic work

Not enough matched evidence
Grok Code Fast 1 is not ranked on the public lane for agentic, so no winner is named for agentic.

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

3 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.

Frequently asked questions
Which is better, Grok Code Fast 1 or Qwen3.6-27B?
Qwen3.6-27B has the higher public score, 52.73 versus 37.21, 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, Grok Code Fast 1 or Qwen3.6-27B?
Qwen3.6-27B scores higher for coding on the public lane, 42.6 to 32.5. Grok Code Fast 1 is scored on Estimated evidence for coding, so the reading is directional rather than like-for-like. BenchLM does not name a winner for coding from a directional reading; read the shared benchmark rows directly and test the models on the same task set.
Which is better for agentic tasks, Grok Code Fast 1 or Qwen3.6-27B?
Grok Code Fast 1 is not ranked on the public lane for agentic tasks, so no winner is named for agentic tasks.
Which costs less, Grok Code Fast 1 or Qwen3.6-27B?
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, Grok Code Fast 1 or Qwen3.6-27B?
Qwen3.6-27B has the larger documented context window: 262K, compared with 256K.
