Tesla FSD Beta 11.4.1 Release Notes with 2023.7.5 Hits Employees

Tesla has released Full Self-Driving (FSD) beta version 11.4.1 for employees, with the latest 2023.7.5 software update.

This update builds on version 2023.6.15 and FSD beta 11.4. On May 7, Tesla CEO Elon Musk said FSD beta would be releasing for employees on May 8. Now it appears a wider rollout is happening.

Here are FSD beta v11.4.1 release notes, as shared by @Winnersechelon:

• Improved control through turns, and smoothness in general, by improving geometry, curvature, position, type and topology of lanes, lines, road edges, and restricted space. Among other improvements, the perception of lanes in city streets improved by 36%, forks improved by 44%, merges improved by 27% and turns improved by 16%, due to a bigger and cleaner training set and updated lane-guidance module.
• Added lane-guidance inputs to the Occupancy Network to improve detections of long-range roadway features, resulting in a 16% reduction in false negative median detections.
• Improved ego’s assertiveness for crossing pedestrians in cases where ego can easily and safely cross before the pedestrian.
• Improved motorbike recall by 8% and increased vehicle detection precision to reduce false positive detections. These models also add more robustness to variance in vision frame-rate.
• Reduced interventions caused by other vehicles cutting into ego’s lane by 43%. This was accomplished by creating a framework to probabilistically anticipate objects that may cut into ego’s lane and proactively offset and/or adjust speed to position ego optimally for these futures.
• Improved cut-in control by reducing lane-centric velocity error by 40-50% for close-by vehicles.
• Improved recall for object partial lane encroachment by 20%, high yaw-rate cut-in by 40%, and cut-out by 26% by using additional features of the lane-change trajectory to improve supervision.
• Reduced highway false slowdowns related to underestimated velocities for faraway objects by adding 68K videos to the training set with improved auto-labeled ground truth.
• Smoothed in-lane offsetting for large vehicles by tuning the amount of lateral jerk allowed for the maneuver.
• Improved lateral control for upcoming high-curvature merges to bias away from the merging lane.

Musk previously said a few days ago the rollout of FSD beta 11.4 will happen “progressively wider as confidence grows. We test as much as possible in simulation and with QA drivers, but reality is vastly more complex.”

He also added earlier this week, “Arguably, v11.4 should be v12.0, as there are so many major improvements. v12 is reserved for when FSD is end-to-end AI, from images in to steering, brakes & acceleration out,” teasing the future capabilities of FSD beta.

Regular testers of FSD beta are currently on version 11.3.6  which released back on April 8. Expect these testers to get FSD beta 11.4.1 in the coming days or weeks.
