The author says they tested Grok 4.6 and Opus 5 with the same prompt:
Grok 4.6: approximately $1.74, completed in about 5 minutes.
Opus 5: approximately 9 minutes, consuming 17% of its daily allowance.
The author asks readers which model won; opinions in the comments are divided. Some consider Opus 5's quality better, while others believe Grok's speed and price advantages are enough to change the choice.
This is not a fully controlled benchmark: the original task, model tiers, harness, and artifact scoring were not fully disclosed in the original post. It is therefore better suited as a subjective cost/speed example than as a quality ranking.
When a task can tolerate one retry and needs to be completed quickly, Grok 4.6's low cost and short turnaround are highly attractive. For tasks involving animation, visual detail, or a higher bar for a high-quality first-pass deliverable, artifact quality should be compared separately.
The figures, task set, reasoning tier, and client conditions apply only to the listed source and collection snapshot. Different versions, harnesses, or providers must not be compared directly; undisclosed parameters remain unknown.
For a reproduction, fix the model version, provider or client, reasoning tier, tools, task-set version, sample count, and collection date, and record failures, retries, and human corrections. Full steps are in the source notes below.
