Sonnet 5.5 completed three passes of every prompt at four effort levels. Xhigh scored 58/60 throughout, but individual answers still changed under classifier and decision-tree instructions. More instructions did not consistently add matches. See scores, changed answers, token use and API-rate costs.
The six fresh Codex comparisons also show unstable prompt gains. Neither added-instruction prompt beat the base task in all three passes for any of these six configurations. Classifier instructions switched between a gain and a loss in four configurations. GPT-6 Luna low ranged from 51 to 55 all-four matches with those instructions; its decision-tree prompt lost two or three matches against the base task in every pass. Compare all six three-pass results.
DeepSeek Flash scored lower with both added-instruction prompts in all three passes. With reasoning off, the base prompt matched all four labels on 48–49 of 60 reviews, classifier guidance on 45–47, and the decision-tree prompt on 43–46. Testimonial agreement improved, while sentiment agreement fell. The same prompt still produced changed classifications on two to four reviews across passes. See the field-level trade-offs and repeat variation.
Across the 17 Claude configurations reviewed on 28 September, neither added-instruction prompt improved all-four agreement over the base task in every pass. Seven configurations switched between a gain and a loss for classifier instructions; seven did so for decision-tree instructions. Those groups overlap. Compare all 17 configurations and the limits of this finding.
Gemma E2B's three fresh local passes scored 35/60 with the original prompt each time, while nine reviews changed a decision. Classifier instructions scored 33–34/60; adding a decision procedure scored 31–33/60 and changed 15 reviews. The earlier local runs are kept separate. Read the field-level differences and local timing limits.
Haiku's classifier-instruction score ranged from 53 to 59 matches out of 60 across three fresh passes. Its advantage over the base prompt changed from two fewer matches to two more. Read the Haiku repeat comparison.
Opus 5 high effort gained two matches from decision-tree instructions in its first two passes, then lost two in the third. See the Opus prompt comparisons.
Sonnet 5 medium gained two and one matches from classifier instructions in its first two passes, then lost four in the third. Opus 5.5 medium scored 58/60 with those instructions in every pass, while one review changed classification. Sonnet results and Opus 5.5 results.
Across 18 Codex configurations, classifier instructions improved agreement in every pass for two configurations; decision-tree instructions did so for none. Twelve configuration/condition groups kept the same score while individual answers changed. Compare all 18 configurations.
Qwen's decision-tree prompt gained a small number of matches in all three passes. On reviews valid in both conditions, P2 gained two, one and two all-field matches over P0. P1's advantage changed direction. Two provider failures required later continuations, so this is a descriptive comparison with interrupted dispatch. See all nine results, changed reviews and retained failures.
DeepSeek low now has results for all nine scheduled passes, including failed answers. Its first P0/P1/P2 scores were 58/57/53 out of 60. The interrupted P2 includes 56 valid answers, one invalid answer and three failures; no reviews remain unsent. In the final pass, P0/P1/P2 scored 58/57/58, with 59/59/60 valid answers. These totals retain failures and do not establish nine clean repeats. See the first-pass outcomes. Compare the final passes and changed answers. Earlier reports: first P0/P1 report and interruption report.
OpenJev generated-off and generated-on have each closed all nine development phases. Across three passes, generated-off P0 scored 48, 51 and 49 all-field matches out of 60; P1 scored 48, 50 and 49; P2 scored 51, 54 and 51. Generated-on P0 scored 54, 53 and 49; P1 scored 50, 46 and 49; P2 scored 46, 47 and 42. Among reviews valid in all three generated-on passes, 8/54 P0, 2/39 P1 and 8/35 P2 reviews changed a four-field answer. Invalid outputs remain in the fixed 60-review scores. These comparisons do not establish an instruction effect. See the separate generated findings.
