ENT_Alam reports that GPT-6 Astra Pro completed all 15 MineBench.ai builds without retries for $34.71 versus GPT-5.6 Sol's $710.82, suggesting substantially cheaper valid builds despite average inference time increasing from 18m 04s to 40m 12s.

What is this?

The case describes ENT_Alam’s reported comparison of GPT-6 Astra Pro and GPT-5.6 Sol Pro on 15 MineBench.ai builds: Astra allegedly completed all builds without retries for $34.71 versus Sol’s $710.82, while average inference time rose from 18m 04s to 40m 12s. Supplied third-party snippets identify Astra and Sol as OpenAI models and discuss broader benchmark and cost comparisons, but none directly documents the MineBench run or corroborates its figures. The material does not establish MineBench’s operators, build-validation criteria, pricing basis, or whether the two runs used comparable harnesses and settings, so the cheaper-valid-build conclusion remains an attributed report rather than a verified result.

Why it matters to Scott

ENT_Alam’s attributed task-cost comparison converges with Scott’s AI Unit Economics lens and bears on his task-aware model routing: substantially cheaper completion at longer latency would warrant a trace-backed comparison on his own fixtures, not an immediate backend switch. The supplied radar pages track related cost and harness questions, not this MineBench development; missing validation criteria, pricing basis and comparable harness settings prevent treating the reported savings as established.
