StudioOctober's 6 hottest models tested on the same agent coding tasks: the most hyped one passed 1 of 5
Original title: October's best models review: I put the month's 6 hottest models through the same agent tasks. The most hyped one passed 1 of 5
The author ran 5 small coding tasks with hidden traps against six models released in October, using Atomic Agent 0.6.13 in cloud mode via OpenRouter, with a 10-minute cap per task. DeepSeek V4.1 Flash, Claude Haiku 5.5, Gemini 4 Argon, Kimi K3.1 Pro and GPT-6.1 Terra all passed 5/5; DeepSeek V4.1 Flash cost $0.02 total with a 14 s median time, versus $0.65 for GPT-6.1 Terra, roughly a 30x price gap. The most hyped model, Recursive Flint (free tier, vendor-claimed 74.2 on SWE-bench Verified), passed only 1/5 and took 8 minutes on one task; the author notes its free endpoint kept erroring and returning 503s, so a rerun through a second agent never got a fair test.
The author benchmarked six new October models on identical trap-laden coding tasks, sharing raw pass rates, times and costs.
