Gemma 4 31B vs Gemma 4 26B A4B

Both Gemma 4 31B and Gemma 4 26B A4B are open-weights foundation models available at $0.00 direct API cost when self-hosted, or offered at identical baseline rates across major inference providers. Model selection depends on GPU deployment sizing and specialized benchmark performance rather than raw token price.

Both Gemma 4 31B and Gemma 4 26B A4B offer an identical context window of 262K tokens (~197k words). Both architectures provide equal capacity for large document ingestion, multi-file codebases, and extended multi-turn conversation histories.

Gemma 4 31B scores 68.5% on SWE-bench Verified while Gemma 4 26B A4B scores 61%. For autonomous software engineering and multi-file debugging, Gemma 4 31B holds the verified benchmark lead.

Gemma 4 31B features native chain-of-thought extended thinking mode with configurable reasoning effort. In contrast, Gemma 4 26B A4B provides chain-of-thought reasoning depth for complex math and science.

Gemma 4 31B generates approximately 80 tokens per second, while Gemma 4 26B A4B delivers 160 tokens per second. In latency-sensitive production environments, Gemma 4 26B A4B provides faster time-to-first-token (TTFT) and higher streaming response velocity.

Yes! Tiered multi-model routing can optimize for latency and accuracy: you can route high-frequency conversational turns and latency-sensitive queries to Gemma 4 26B A4B, and route deep architectural or complex reasoning queries to Gemma 4 31B. This balanced routing strategy maximizes system throughput and answer quality.
