When to choose each
Gemini 4 Argon
Best for
- Long-horizon coding and knowledge work once it reaches general API access
Watch out for
- Access is limited: Google is rolling it out first to cyber defenders in its Fairwind Program, and no Gemini API model id or pricing page entry exists yet
- The $2 input and $10 output rate is introductory with no end date; Google says $4 and $20 per 1M tokens applies afterwards
- Google has not published the context window
GPT-4.1
Best for
- Long-context API trials using text and image inputs
Watch out for
- Not in the pinned LiveBench snapshot; its independent scores here come from Epoch AI's own GPQA Diamond, FrontierMath and SimpleQA Verified runs
