Gemma 4 26B A4B vs Gemma 4 E4B
Updated August 15, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload. This is a same-family comparison, so migration details appear when the source data supports them.
Decision reading
Gemma 4 26B A4B has the higher public score estimate, 57.16 versus 43.25, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.
1 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.
Which one for your work
Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

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

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.

Frequently asked questions
Which is better, Gemma 4 26B A4B or Gemma 4 E4B?
Gemma 4 26B A4B has the higher public score estimate, 57.16 versus 43.25, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.
Which is better for coding, Gemma 4 26B A4B or Gemma 4 E4B?
The published evidence does not provide a shared weighted coding basis for both models, so BenchLM does not name a coding winner.
Which is better for agentic tasks, Gemma 4 26B A4B or Gemma 4 E4B?
The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.
Which costs less, Gemma 4 26B A4B or Gemma 4 E4B?
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, Gemma 4 26B A4B or Gemma 4 E4B?
Gemma 4 26B A4B has the larger documented context window: 256K, compared with 128K.
