URL: https://howaihelps.com/articles/agent-iq Published: 2026-06-23 Description: I gave the same visual IQ test to six coding agents — Claude Opus, Sonnet, and Codex — and compared score, time, and cost. The results were not what I expected. Direct answer: In this visual IQ-test experiment, Codex 5.5 performed best. The strongest run was Codex 5.5 on the $200 plan with IQ 131; Codex 5.5 on the $100 plan scored IQ 124. Claude Opus runs scored IQ 90, Claude Sonnet scored IQ 68, and Codex 5.4 scored IQ 101. This is an anecdotal tool test, not a scientific model ranking. Key facts: - Task: complete 25 visual puzzles on iq-test.cc, select age 30, and return the result link. - Best score: Codex 5.5 on the $200 plan, IQ 131 in about 34 minutes. - Best like-for-like prompted run: Codex 5.5 on the $100 plan, IQ 124 in about 18 minutes. - Main pattern: agents that organized the visuals before answering did better than agents that solved one screenshot at a time. FAQ: - Q: Which coding agent got the highest IQ score in the test? A: Codex 5.5 on the $200 plan got the highest score, IQ 131. Codex 5.5 on the $100 plan scored IQ 124, which was the best run with the stricter age-30 instruction. - Q: Was this a scientific benchmark of AI agents? A: No. It was a practical anecdotal experiment using one public visual IQ test, meant to compare behavior, time, cost, browser handling, and visual problem-solving style. - Q: What seemed to matter most for a high score? A: The strongest runs organized the puzzle images first, zoomed into hard questions, and revisited uncertain answers before submitting.

Direct answer: Seedance 2.0 was the best AI video model in this test. It followed the first-person parachute prompt most completely, kept the helmet-camera feeling, included sound, and cost about $2.43. Veo 3.1 looked premium but rejected the original prompt and lost the first-person view on retry; Kling v3 Pro looked good but had weak motion; Wan 2.7 was cheap but not usable. Key facts: - Test prompt: first-person BASE jump from a 150-meter abandoned smokestack into one muddy puddle. - Models compared: Seedance 2.0, Kling v3 Pro, Veo 3.1, and Wan 2.7 on fal.ai. - Winner: Seedance 2.0, because it followed the full idea with the least confusion. - Approximate working-clip costs: Seedance $2.43, Kling $1.34, Veo $3.20, Wan $1.20. FAQ: - Q: Which AI video model won the parachute prompt test? A: Seedance 2.0 won because it best preserved the first-person camera, parachute action, story rhythm, and overall prompt intent. - Q: Was the cheapest AI video model the best choice? A: No. Wan 2.7 was the cheapest working render at about $1.20, but the clip did not hold together. Seedance 2.0 cost more but produced the most usable result. - Q: Why did Veo 3.1 not win? A: The original Veo 3.1 run was blocked by a content-policy error. A softened retry rendered a good-looking clip, but it changed the first-person prompt into a third-person shot.

It is how developers frame problems — define the output, test the edges, weigh tradeoffs, and iterate. Anyone can borrow the habit. Direct answer: Developers often get better AI results not because they know syntax, but because they frame problems clearly. The transferable workflow is to define the desired output, give examples, test weak spots, ask for tradeoffs, and iterate. The article calls this thinking engineering rather than prompt engineering. Key facts: - The advantage is problem framing, not secret prompt vocabulary. - Useful AI prompts specify format, length, tone, examples, constraints, and success criteria. - Good users review AI output like a draft: they test assumptions, compare options, and refine. - The same workflow works for writers, marketers, founders, analysts, operators, and managers. FAQ: - Q: Why do developers often get better results from AI? A: They usually define the target output, provide context and examples, test edge cases, compare tradeoffs, and iterate instead of accepting the first response. - Q: Do you need to know code to use AI well? A: No. Coding can help in some tasks, but the bigger skill is clear thinking: deciding what good looks like and giving the model enough context to aim there. - Q: What is thinking engineering? A: Thinking engineering is the habit of shaping the problem before asking AI for an answer: define the output, show examples, probe weak spots, weigh tradeoffs, and iterate.
