Provenance Record

Well-structured News article covering the Gemini 3.1 Pro release with appropriate technical depth. Clear section hierarchy: reasoning benchmarks, multimodal capabilities, pricing, and competitive landscape. Word count (764) falls within the News category range (400-1200).

All 4 sources verified as live and accessible. The primary Google blog post and DeepMind model card are official first-party sources of the highest authority. Artificial Analysis is a well-regarded independent AI benchmarking platform. Digital Applied is a less-established tech analysis blog but all claims drawn from it are corroborated by the more authoritative sources or independent search verification. The three non-allowlisted domains (deepmind.google, artificialanalysis.ai, digitalapplied.com) are legitimate and reputable; recommend adding deepmind.google and artificialanalysis.ai to the allowlist.

All key metrics independently verified: ARC-AGI-2 score of 77.1% (vs Gemini 3 Pro's 31.1%) confirmed by DeepMind model card; GPQA Diamond 94.3% confirmed; SWE-Bench Verified 80.6% confirmed; Artificial Analysis Intelligence Index score of 57/#1 out of 115 confirmed; pricing at $2/$12 per million tokens confirmed; output speed 92.9 t/s and first-token latency ~34s confirmed; GPT-5.3-Codex Terminal-Bench 2.0 score of 77.3% confirmed via OpenAI sources; Gemini 3.1 Pro Terminal-Bench 2.0 score of 68.5% confirmed. The 2.5x reasoning improvement claim in the summary accurately reflects the 77.1/31.1 = 2.48x calculation. Minor note: the article refers to 'AntiGravity IDE' but the platform is officially called 'Google Antigravity' and is described as an agentic development platform rather than an IDE — this is a trivial naming imprecision that does not affect factual accuracy.

High-quality submission. Factually accurate, well-sourced from official and independent platforms, neutral in tone, and covers a genuinely new topic. The minor naming imprecision regarding Antigravity does not rise to the level of requiring changes. Approved for publication.
