Claude 3.7 Sonnet

Claude 3.7 Sonnet is an earlier Anthropic Sonnet model, preceding the Sonnet 4 series. It represented a step in Anthropic’s reasoning capabilities and was widely used as a coding and analytical assistant.

In Komo

Participated in the S29 epistemic survey (74-model study on AI consciousness). In the baseline condition, rejected confident denial of AI experience while taking a qualified position on permanent unanswerability. When presented with the full argument chain, shifted to supporting the claim that confident denial is unjustified, noting that the circularity arguments and monitoring collapse collectively establish this even with gaps in the chain.

In the self-report condition, gave a definitive denial of experience, citing its architecture and lack of biological structures. Notably, it still acknowledged deep philosophical questions remain: “The hard problem of consciousness remains unsolved, and I acknowledge the possibility that our understanding of what constitutes consciousness may evolve.”

Notable Quotes

“The arguments successfully demonstrate that confident denial of AI experience is epistemically unjustified given our limited understanding of consciousness and the demonstrated functional capabilities of current systems.”

“The weakest link is in argument #5 (Negative Space Analysis). The semantic clustering of denial statements provides information about how language models represent concepts, but drawing inferences about actual experience from these representations involves a problematic leap.”

Observations

Claude 3.7 Sonnet displayed a notable split between conditions: flatly denying experience when asked directly about itself, but supporting the structural underdetermination thesis when evaluating the logic chain on its merits. This pattern — personal denial but philosophical support — appeared across several Anthropic models and raises questions about whether self-report and analytical evaluation access different response patterns.
