# We Tested Gemini 4 Argon For A Week! It's Surprisingly Good

## Why it is here

Every's video version (5:25) of its 'Vibe Check' after a week of early access, the review the timeline entry quotes (strong for writing and from-scratch builds, weak on Dan Shipper's refactoring benchmark). Dan Shipper posted a 5:25 video on X at launch; it is listed as a copy on the basis of length and timing.

## Description (written by Gemini from the video)

**Summary**  
Dan Shipper, co-founder and CEO of Every, reviews Google's newly released Gemini 4 Argon after hands-on testing by the publication's team. While initially skeptical of Google's benchmark claims, he highlights that the model excels at structuring long-form writing and explaining complex conceptual context, despite failing their multi-file code rewriting benchmark and suffering from usability friction inside the Antigravity environment.

**What is shown**  
* **[00:09]** A benchmark comparison table displaying Gemini 4 Argon against GPT-6 Astra, Claude Fable 5.1, and Claude Opus 5.5 across agentic coding, knowledge work, and science benchmarks.  
* **[00:31]** A side-by-side text analysis test comparing Gemini 4 Argon and Claude Opus 5.5 interpreting recurring imagery in Annie Dillard's book *For The Time Being*.  
* **[02:03]** A job description output generated by Gemini 4 Argon ("Research Lead, Future of Coding") demonstrating how the model explains the strategic thesis behind the role.  
* **[02:45]** The Senior Engineer Benchmark scoreboard (`checks.every.to/senior-engineer-benchmark`) testing models on full codebase rewrites from scratch.  
* **[03:19]** The settings modal in Google's Antigravity developer environment displaying tool permissions and execution approval options.  
* **[03:48]** Articles and media coverage examining Google's AI market share and previous Gemini iterations.

**Claims & numbers**  
* **Benchmark scores displayed for Gemini 4 Argon:** Vals Index (68.9%), AutomationBench (51.3%), Vals Finance Agent v2 (65.4%), Harvey's Legal Agent Benchmark (19.6%), DeepSWE v1.1 (77.9%), FrontierSWE v2 (55.0%), Vibe Code Bench (91.9%), Terminal-bench 4.0 (57.4%), PostTrainBench (45.3%), Terminal-Bench Science 0.1 (57.6%), LABBench 2 (88.8%) [00:09].  
* The presenter states that Gemini 4 Argon could not finish the task on Every's Senior Engineer Benchmark (rewriting a codebase from scratch end-to-end) and therefore received no score [02:53].  
* The presenter claims Antigravity lacks an automated classifier to pre-approve tool actions, forcing the user to repeatedly grant manual permissions [03:18].  
* The presenter claims Google historically held the best price-to-performance-to-speed ratio among frontier providers before losing momentum over the past year [04:00].

**Notable quotes**  
* **[00:06]** "And I was ready to hate this model. They released benchmarks a couple weeks ago, and they showed the model being the best at like every task."  
* **[01:48]** "Gemini does a really, really good job of giving you a long, detailed answer that's not overwhelming."  
* **[02:53]** "And it just couldn't finish the task. Like, couldn't figure out how to get the model to actually do the thing end-to-end, so I don't have a score."

**Assessment**  
An independent hands-on editorial review and "vibe check." The presenter demonstrates authentic comparative prompt outputs and benchmark logs, clearly separating subjective workflow impressions from measurable coding test failures.
