- Con: Opus 5.5 cost about 20 times more than GPT-6 Sol on the codebase repair test [26:50]
- Vs: On the codebase repair benchmark, GPT-6 Sol scored 100/100 (30/30 checks) versus Opus 5.5's 96.7/100 (29/30 checks), with Sol costing about $1.04 versus Opus's $19.82 [26:50]
- Vs: GPT-6 Sol stopped mid-task on the codebase test due to a cybersecurity/safety trigger, requiring the prompt to be resent, while Opus did not stop [27:07]
- Vs: On the Canva test, Opus was about 30 minutes slower and roughly four times more expensive than Sol, but its output was much better [31:36]
- Reason: The reviewer's core takeaway is that despite Opus 5.5 costing far more across nearly every task, its output quality was consistently better, leading to the 7-1 overall verdict in its favor [24 wins tally referenced at 31:45]
How this brief was shaped: Evaluation (review / comparison / unboxing) · confidence High
The creator runs Opus 5.5 and GPT6 Soul across 10 identical use cases, opens by comparing pricing, and repeatedly judges outputs against each other like the pitch deck and financial report task. This is a head-to-head model comparison with verdicts per task, not a single tutorial or lecture.
The lens sets this brief's structure, never its facts — every claim is held to the same citation and fact-check standard.
