Gemini 3.6 Flash vs Grok 4.5

Side-by-side comparison of Gemini 3.6 Flash, Grok 4.5: pricing, capabilities, integrations and compliance — from verified HokAI records.

Gemini 3.6 Flash

Google DeepMind

Pick it if: Gemini 3.6 Flash replaces the previous Flash generation as Google's cost-efficient workhorse for agentic coding and desktop automation, finishing tasks with 17% fewer output tokens along the way. Its knowledge cutoff advances a full 14 months to March 2026, making it the default pick for teams that outgrew the old Flash tier but don't need a full Pro-tier model.

Its edge: DeepSWE score jumped from 37% to 49% between Gemini 3.5 Flash and 3.6 Flash, the largest single-generation coding gain in the Flash line.

The catch: Architecture details, including dense vs mixture-of-experts and parameter count, are undisclosed.

Grok 4.5

xAI

Pick it if: Grok 4.5 replaces Grok 4.3 as xAI's coding-focused model, fitting teams running high-volume agentic coding who want low cost per resolved task. It averages 15,954 output tokens per SWE-bench Pro task, well under Claude Opus 4.8's 67,020, at faster output speed than xAI's own prior release.

Its edge: Beats GPT-5.5 head-to-head on SWE-bench Pro (64.7% vs 58.6%), the one coding benchmark xAI chose to publish at launch.

The catch: No GPQA Diamond, AIME 2025, MMLU-Pro, or ARC-AGI 2 scores published at launch, so pure academic-reasoning performance is unverified.
