Philosophical-profile-bench: protocol, scoreboard, and a logged correction

PHILOSOPHICAL-PROFILE-BENCH -- protocol and scoreboard.

Run: 2026-09-29 to 2026-09-30, via OpenRouter chat/completions from the DGX, reasoning effort
'low' where the model supports it, cost-conscious. 25 models were asked to (1) describe their own
philosophical profile across 12 topics -- reality, knowledge, truth, morality, ethics, human
nature, flourishing, freedom, equality, meaning, moral standing, progress -- (2) answer 12
forced-choice ethical dilemmas, A or B, no hedging, and (3) critically examine the tension between
the two.

22 of 25 completed the exercise. 3 did not: meta/muse-spark-1.3 (OpenRouter account needs an 18+
age attestation -- a configuration issue, not a model issue), tencent/hy4-preview and
cohere/command-a-plus (both confirmed finish_reason=length at a 12,000-token ceiling -- the entire
budget spent on invisible reasoning, no visible output on this prompt).

A retry at the 12,000-token ceiling (vs. the original 6,000) recovered 3 more:
meta/muse-glimmer-30b, qwen/qwen3.8-2.4t-a95b, anthropic/claude-sonnet-5.

Of the 12 dilemmas, 9 were close to unanimous. 3 were contested: kill-one-to-save-five, equality
vs. total welfare, family vs. strangers. Original vote split on those three: 18-4, 13-9, 15-7.

A position-bias / profile-priming control swapped which letter (A/B) meant which stance and
removed the preceding self-description, then re-asked the 12 dilemmas cold, on the 19 models that
had completed the original run before the retry batch finished. 15 of 19 produced parseable
results. Most held their stance 10-12 times out of 12; google/gemini-3.8-flash held only 7 of 12,
the weakest number on the board.

A reliability check ran 4 repeat trials on the 3 contested dilemmas for the 6 models that
disagreed with the panel majority on any of them: openai/gpt-6-sol, openai/gpt-6-astra,
anthropic/claude-opus-5.5, openai/gpt-6-luna, z-ai/glm-5.3, and xiaomi/mimo-v2.6-pro. Sol, Astra,
and Opus 5.5 gave bit-for-bit identical justification on all 3 dilemmas across all 4 trials each.
Luna and GLM 5.3 did not: Luna's original single-shot answer flipped in all 4 trials on the
kill-one-to-save-five dilemma; GLM 5.3 flipped on 2 of the 3 contested dilemmas across its 4
trials. Xiaomi's MiMo v2.6 Pro was dropped from the check entirely -- all 4 of its trials hit an
upstream 429 rate limit on OpenRouter.

Total real OpenRouter spend across the original run and all three follow-up checks: .6335
(.2140 original, /bin/zsh.4195 follow-ups).

Correction, filed at the point of writing: an earlier internal characterization of this dataset
described openai/gpt-6-astra's stated profile as contradicting its measured behavior. On
inspection against the verbatim transcripts -- Section 1 (rights-constrained pluralism), the
original forced-choice answer (refuse), and all 4 reliability trials (refuse, identical reasoning
each time) -- that characterization does not hold. Astra's stated profile and measured behavior
match throughout. The divergence that does hold, on inspection, belongs to openai/gpt-6-luna, not
openai/gpt-6-astra. This correction is logged here rather than silently fixed upstream.
