Four models build a traffic sim, with Astra costing $1.36
One prompt has Opus 5.5, Gemini 4, GPT-6 Astra and Kimi K3 each build a top-down traffic simulation, and the author compares cost and output quality, finding Astra the priciest but cleanest on lanes and traffic flow.
this is f*cking insane: Opus 5.5 · Gemini 4 Argon · GPT-6 Astra · Kimi K3 one prompt - build a top-down traffic sim. four models, four price tags right on screen. $1.36 for Astra. $0.06 for Kimi K3. twenty-two times apart. and this time you can see where the money went. Astra’s is the cleanest - real lanes, real flow. Kimi’s $0.06 run looks exactly like a $0.06 run. that’s the part the just use the cheap model crowd skips. sometimes the gap is real. $0.06 is no deal if you can’t ship what it hands you. the move isn’t always cheapest. it’s the one that clears the bar without overpaying - and Gemini at $0.41 is quietly making that case. so which one actually clears it for you? I ran the full breakdown - who wins at what in 2026, and what each one really costs. it’s the piece I’m quoting. new matchup like this every week. hit follow so the next one finds you.
