Comparing the first 1,000 you can see there have been a lot more K80s recently. It doesn't show here but in the last 1,000 attempts 640 were unique; including 380 unique for T4s out of 594. That tells me either I'm still a ways short of seeing all GPUs colab has ... or they have been replacing them regularly: probably a little of each. Code:  TYPE: TOT UNIQ ALL: 5000 3658 T4: 4182 2889 P100: 297 281 P4: 145 129 K80: 376 359 ALL: 1000 904 T4: 927 832 P100: 39 39 P4: 27 26 K80: 7 7

Lately I get almost half K80 and almost half T4....with sporadic P4 and P100

 2021-07-21, 18:11 #1159 moebius     Jul 2009 Germany 607 Posts Since one month I only be able to get T4/P4 or sometimes K80 instances (5-6 hours) at free google colab. Are the good times at colab over? Are P100 runtimes still available for other free users? Last fiddled with by moebius on 2021-07-21 at 18:21

No P100 for me for several weeks.
And lately very few K80.

I find that the CPU gives you 12 hours/session IF you respond to an "are you human" request that appears some random time from 6 hours to 6:40 into the session. If you don't respond to that, your session is killed some time later (rarely lasting longer than 7 hours). If you do respond, the session will generally be killed after the 12 hour mark (for me it's generally a few seconds to about 5 minutes after the 12 hour mark). A new CPU session can be restarted immediately after the last one ends.

If the GPU session is going to last longer than 3 hours, shortly after 3 hours I get an "are you human" request. If I respond to that the session may last longer than 4 hours, and sometimes (very rarely) I've had a much longer GPU session. If I don't respond to the "are you human" prompt, then the session gets killed 3:45 to 3:50 (if it doesn't stop abruptly before that).

Sometimes I get just over an hour on the GPU, but I average around 3 hours.

For a while now I've only been getting T4 and the occasional K80 for GPU.

Sometimes an account can't get a GPU for 7-14 days, then one day it gets the GPU again with a very short session (maybe 65 minutes), and then the sessions get longer again after that it until it's back in with the normal mix of times I get on GPU sessions.
