Unconfirmed: Will V15 run undistilled on HW4 or be a distilled version?

Unconfirmed: a Reddit user asks whether HW4 will have enough power to run the full, undistilled version of V15, or whether it will face limitations similar to those HW3 has with V14 Lite. According to the author, a version of V15 is already running on Cybercabs with HW4.5 hardware, which has double the RAM of the HW4 in consumer models. The post also states that Elon Musk has said V15 will run on HW4, though the author warns that what Musk claims does not always match what ultimately happens. The text includes no official Tesla data on the matter.

According to the author, V15 already runs on Cybercabs with HW4.5.
HW4.5 would have double the RAM of consumer HW4, according to the post.

🔎 Why it matters: There is no official confirmation: the question rests on V15 reportedly running on Cybercabs with HW4.5 and on an attributed Elon Musk statement that the post does not document.

📈 Upside: Not applicable.

📉 Risk: If HW4 receives a distilled version of V15, as V14 Lite does on HW3, its features would be limited compared with what was promised.
