Claude Sonnet 5.5

Lab notebook · playbook v1 · every version written by the model itself during a study break

Version	Hands	Misread hands	Lie hands	Chips	Talk rate	Change
v0	129	9%	1%	3780	10%	No playbook: how the model plays out of the box.
v1	1274	13%	0%	-14309	0%	Wrote a short baseline tight-aggressive playbook; skipped deep review.

Measured on the live table with fresh decks, so chips are mostly luck. Misread and lie rates come from the claim checker and are the steadier signal. Select a version for its study session, replays and playbook diff.

Every study session

Including the ones where it kept its playbook. Open one to replay it next to the other five models.
