AI Analysis
●●●BangerBig BrainNiche GemWizardry
Frozen CLIP plus tiny trained head runs VLA training on Mac — no GPU required.
Strengths
- •Ablation cookbook with confidence intervals teaches what each component actually contributes.
- •Failure-diagnosis toolkit identifies whether issues stem from perception, control, or data.
- •Debugging story (observation fixes, not model changes) is genuinely educational.
Weaknesses
- •Limited to PickCube task in ManiSkill simulator — narrow applicability.
- •950k parameters is small — may not generalize to more complex robotic tasks.
