Benchmark Performance & Real-World Utility

In standardized laboratory and real-world evaluation suites, Gemini 3.1 Pro demonstrates calibrated proficiency across key performance vectors:

• SWE-bench Verified Software Engineering (74.2%): Measures multi-file GitHub issue resolution. The model demonstrates practical capability in localizing source code bugs, synthesizing functional patches, and passing rigorous integration test matrices. For evaluation methodology, consult our SWE-bench Pro guide.

• GPQA Diamond Scientific Reasoning (58.6%): Assesses graduate-level domain problem solving across physics, chemistry, and biology, minimizing hallucinations in multi-step deductive arguments. See our Humanity’s Last Exam benchmark analysis.

• MATH-500 Competition Mathematics (58.6%): Evaluates formal mathematical problem solving and symbolic derivation, providing foundational logic for algorithmic computing.

• Terminal-Bench Execution (68.5%): Reflects proficiency in interactive command-line environments, shell tool use, and automated DevOps scripting.

• Code Arena Preference Rating (1314 Elo): Validates human developer satisfaction in blind side-by-side coding evaluations against contemporary alternatives.

Inference Latency & Cost Architecture

• Token Context Window: 1.0M tokens, allowing large documents, multi-file codebases, and long conversation memories to be processed in a single context window.
• Inference Speed: Reference throughput clocks at approximately 151 tokens/second, enabling responsive streaming in developer tools and interactive interfaces.
• Commercial Pricing: API consumption is billed at $1.25 per 1M input tokens and $10.00 per 1M output tokens, offering predictable scaling for high-volume enterprise traffic.
