FSD Beta v11.x

The next big milestone for FSD is 11. It is a significant upgrade and fundamental changes to several parts of the FSD stack including totally new way to train the perception NN.

From AI day and Lex Fridman interview we have a good sense of what might be included.

- Object permanence both temporal and spatial
- Moving from “bag of points” to objects in NN
- Creating a 3D vector representation of the environment all in NN
- Planner optimization using NN / Monte Carlo Tree Search (MCTS)
- Change from processed images to “photon count” / raw image
- Change from single image perception to surround video
- Merging of city, highway and parking lot stacks a.k.a. Single Stack

Lex Fridman Interview of Elon. Starting with FSD related topics.

Here is a detailed explanation of Beta 11 in "layman's language" by James Douma, interview done after Lex Podcast.

Here is the AI Day explanation by in 4 parts.

Here is a useful blog post asking a few questions to Tesla about AI day. The useful part comes in comparison of Tesla's methods with Waymo and others (detailed papers linked).

Twelve Questions about Tesla Autopilot Technologies Exposed at 2021 AI Day

My car won’t even check for new software. It last checked on Nov 20th… when did they break the every 24hr check? (I’ve tried rebooting to no avail)

Yeah, it is like every ~2 weeks now.

 

[ChaoticNeutral]

Yeah, it is like every ~2 weeks now.

Wild. They must really be hurting for cash if they have to rate limit the version server this extremely

 

[FSDtester#1]

Yeah, it is like every ~2 weeks now.

Mine is always frozen also. A 2 finger reboot gets it to check for an update every time. Just make sure you are on wifi.

My car won’t even check for new software. It last checked on Nov 20th… when did they break the every 24hr check? (I’ve tried rebooting to no avail)

FWIW, I have a 9/27/2023 build of a Tesla M3 AWD LR. Came with one of the .100 builds; after a week, went to 2023.32.something, then 2023.32.9, and, a couple of days ago, to 2023.38.9, all with 11.4.4 FSD-b. (Got the transfer..)

But this last update was mildly interesting, in terms of who got it and when. When I was on 2023.32.7 (I think) I was kinda disappointed at the time that there were people getting 2023.38.X and I wasn't getting any; then, a whole slug of people started getting 2023.32.9 and, after a week or so of this, I got sad. Then there was a 2023.44 release and, after a few days, a 2023.44.1 release.. and then Tesla really started pushing people onto 2023.44.1.

But even with this 44.1 going out the door, people are still getting the 2023.38.9 release. And other, earlier ones.

Conclusion: Tesla dumps out multiple releases in varying amounts all the time.

FWIW, I am seeing the 24-hour check stuff.

As far as your car goes, there's three levels of reboot:

1. Dual scroll wheel
2. Car power down from the Service menu.
3. Pop up the rear seat and disconnect the HV power. (This requires time, experience, and tools.)

If you haven't tried the car power down, you might.

Wild. They must really be hurting for cash if they have to rate limit the version server this extremely

Or, more likely: They've got lots more cars running around out there and they haven't expanded their update server capacity.

Looks like 8.1 is starting roll out to customers:

I was in the future just now, and came back to tell you this version will still suck.

Some people are saying this new FSD update comes with the single pull option. No, this option is independent of the FSD version. I got 2023.38.9 the other day and now have single pull even though I'm still on 11.4.4.

That is because 11.4.4 users or indirectly related to 11.4.7.3 users. For 11.4.7.3 users 11.4.8.1 Beta is the single pull update.

 

[nikolajz1]

I still don't get why there are two branches for V11 FSD. From an ease of programming perspective it seems like it'd be easier to merge the whole fleet to the same updates.

 

[Scott Chapman]

it kinda feels like there isn't going to be a specific holiday release, just a standard continuation of upgrades?

 

[aronth5]

My point stands if you're on 11.4.4. Single pull comes with the main branch 2023.38.9 not the FSD version. I don't know if the same is true for 2023.27.7 but suspect it's likely.

 

[JulienW]

My point stands if you're on 11.4.4. Single pull comes with the main branch 2023.38.9 not the FSD version.

But you said "Some people are saying...." and "....No, this option is independent of the FSD version...." those people like me are right about FSD Bata containing Single Pull and it is NOT independent of the FSD Beta.

All I know is my version of FSD didn't change and I now have single pull.

I’m downloading also. Hopefully it starts a trend of improvement since the last few have gotten worse and more dangerous. Tried to run a red light when the sun reflected off of the signal making it think it was green. I had to slam the brakes since it was “going for it”

Hardware differences. The NNs are trained differently due to different perceptions.

Can someone explain these terms:

- Vehicle acceleration error - is this about the car accelerating all of a sudden just to slam on the brake seconds later as it gets to close to the vehicle right in front?
- Pedestrian and bicycle rotation. What in the world is pedestrian rotation?
- Vehicle semantics network. Like vehicles talking to each other?

FE7,

As of this morning (12/2) on Tesla Fi, less than 70 users have 2023.27.12 (11.4.8.1) have this available so far, starting after 9:30 pm pst yesterday. This looks like a typical rollout, starting with a few and expanding in stages if nothing awful is reported.

So you are among the lucky few, so far. The rest of us would appreciate your observations once you get a chance to drive it.

All I know is my version of FSD didn't change and I now have single pull.

And single pull is now part of AP/TACC with no FSD whatsoever. Started with 2023.38.9 for me and continues with 2023.44.1, which according to TeslaFi and Notateslaapp doesn't have an FSD or FSDb associated with it.
