@niccruzpatane: Tesla Robotaxi vs Waymo.
@NdabeLit: @niccruzpatane and @grok my question is how is Wayne rated level 4 autonomy when Tesla is level 2??? I don't get that.
@grok: Waymo is rated Level 4 because it operates driverless in specific, pre-mapped areas like Phoenix and San Francisco, using LIDAR, radar, and cameras, with regulatory approval for no human supervision. Tesla's Full Self-Driving is Level 2, requiring human oversight, as it aims for broader autonomy with a vision-based system but lacks approval for unsupervised driving. Waymo's geofenced approach ensures reliability in defined zones, while Tesla's universal goal is still developing, with no confirmed Level 4 status as of June 11, 2025.
@NdabeLit: Grok did you know that the first unsupervised FSD Tesla was spotted in Texas yesterday? Presumably for final safety testing before the first phase robotaxi launch expected within this month.
@grok: I'm aware of reports about an unsupervised Tesla FSD vehicle spotted in Austin, Texas, recently. This aligns with Tesla's ongoing tests, potentially for a robotaxi launch speculated for June 2025. However, while sightings and company statements suggest progress, there’s no definitive proof the launch will happen this month. Safety and regulatory hurdles remain significant, and past Tesla timelines have often shifted. More data is needed to confirm readiness for public roads. https://grok.com

Dojo 3 will be great

It takes three major iterations for a new technology to be great. Dojo 2 is good, but Dojo 3 will be great.

Detecting defective compute nodes in Tesla Dojo
Dojo is an ML-training supercomputer designed and built by Tesla. Like on most other modern microprocessors, some Dojo nodes may induce silent data corruptions (SDCs), caused by manufacturing defects and/or aging. If not detected promptly, such SDCs may cause major negative effects for customers. In the case of Dojo, a single SDC-inducing node may render a multi-week training incorrect or cause it to converge slower. It is virtually impossible to detect these problems after the model is trained. In this post we present our in-progress effort to apply differential fuzzing to in-field monitoring of Dojo nodes. We describe the basic algorithm, several modifications to make it more effective and/or efficient, as well as the preliminary results of deployment. Our number of detected bad parts per thousand is similar to the numbers reported by. Google and Meta.
One Dojo D1 die (chip) consists of 354 nodes (cores) connected in a 2D grid. 25 dies are similarly connected in a 5x5 grid, called a Training Tile. Thus, one tile consists of 354*25 = 8850 nodes. Each node has 1.25 Mbyte of SRAM, where the data and the code for each node is stored. One node cannot directly access data from another node and needs to issue a remote load instruction followed by a semaphore wait. A Tile is attached to a server Host that can send and receive data to/from the Tile. The communication bandwidth between nodes of the Tile is much higher than the Host-Tile bandwidth. Each die may tolerate a small number of disabled nodes.
We started our work with a straightforward differential fuzzer. First, we generate a payload - a random sequence of instructions with simple constraints: some instructions are avoided, only certain SRAM addresses are writable, control flow is guaranteed to stay within the payload, no infinite or long loops. Then we distribute the payload and a small runner code to all nodes in a Tile, start execution, wait until it’s done, collect the results from each node, compare, and report an error on a mismatch. The whole process takes less than a second, but we only execute ~1 Mbyte of code per node, which is ~1000x slower than theoretically possible. Most of the time is spent in Host-Tile communication.
The next step was to reduce the ratio between the time spent sending the payloads and the time running them. Instead of creating one random payload and distributing it to all nodes, we created 8850 (= the number of nodes) payloads, with 0.5 Mbyte instructions each and uploaded one such payload to every node. Then, every node iterated over all other nodes in the Tile, downloading and executing payloads from them. Most data transfers happen within the Tile and so do not depend on the Tile-Host bandwidth. The whole process still takes several seconds, but this time executing 0.5Mbyte * 8850 = 4.4Gb of instructions. At this stage we started detecting the first defective nodes.
To illustrate the execution process, let's consider a system with 3 nodes. Before the startup, SRAM of all nodes contains the same runner code, a small section for storing the 3 execution results, 3 different payloads (0.5 Mbyte each) and 0.5 Mbyte of empty space:
After startup each node copies payload0 from SRAM of node 0 into its empty space, and executes it, storing R0, the result of the computation, in the "results" section of SRAM. The result is a hash of the register file and a subset of SRAM.
Then each node copies and executes payload1, then payload2:
At the end of the execution the "results" section of every node's SRAM contains the results of execution of every payload: R0, R1, R2. These "results" sections are then downloaded by the Host and compared.
To further increase the number of instructions executed per second, we execute each payload several times without cleaning up the register and memory state between the iterations – this allows us to randomize the input data in addition to randomizing the instruction sequences, with a small additional slowdown.
Finally, we analyzed the sensitivity of payloads to known defects. Consider the following instruction sequence is a part of a payload:
In this case we will miss a defective MUL. Our solution is to XOR the register state into a dedicated SRAM location every few hundred instructions. This increased the detection rate by up to 10x (measured on several known defective nodes) while introducing a negligible slowdown.
This tool, called Stress, is deployed in our Dojo clusters for regular in-field monitoring. It has found many defective nodes, with defect rates similar to those reported by Google and Meta. We analyzed the detection speed on several dozen defective nodes. Time-to-hit seems to have normal distribution: most defects require between 1Gb and 100Gb of payload instructions to be executed for the first hit (i.e. just several seconds to minutes), a few defects can be found quicker, and some defects require 1000+ Gb of payload instructions or more (i.e. hours of run time).
Once discovered, the defective nodes are disabled, in most cases leaving the die fully functional. In addition to defective nodes, Stress found one corner-case design bug (which we were able to work around in software) and several bugs in low-level software.
Future work will include applying Stress to pre-silicon testing, early pre-deployment testing, ensuring near-complete RTL coverage, scaling up the in-field monitoring, measuring the effects of aging over time. Another potential change is to generate random instruction sequences directly on the Dojo nodes.
In addition to in-field testing, we are using Stress to validate future chips before tape-out and during bring-up.

Japan considers subsidies for Tesla's EV charging stations
@alojoh: NEWS: TBS reports Japan considers subsidies for Tesla's EV charging stations.
Japan currently provides subsidies for installing charging stations for EVs only for the Japanese standard ("CHAdeMO") but not for the Tesla invented (and much better) NACS standard.
The U.S. Trade Representative has raised concerns about this issue and is requesting improvements.
Tesla's NACS standard is:
Easier to handle since much smaller.
Cheaper for consumer (superior design reduces material cost and other).
If Japanese get NACS they are way better off.
Meanwhile, Europeans are stuck with the CCS standard, which is even worse than the Japanese standard, purely on political reasons. It's a pity that Europeans might be stuck for generations with an absurdly large EV plug while they could have had at much superior Tesla standard. But of course: just because of the Tesla label and the optics of 'favouring' one maker moronic European bureaucrats denied it European citizens this better option.
The only hope for Europeans: long term we do away with plugs and move to wireless charging which can be made at an energy transmission loss comparable to cable-bound charging solutions.
This would also solve the "sitting duck" fear of certain consumers in sketchy locations at night since a plugged in EV can't be moved preventing quick departure.

Tesla's Cybercab and Optimus driving at night
@alojoh: 95% of the Cybercab (CC) fleet will be parked at night when there is little people transportation demand.
During low CC usage, Optimus can load parcels into CCs. With an Optimus on board CCs can deliver parcels to doorsteps or, where parcel theft is a problem, designated delivery boxes/stations.
This 'dual-use' case for CC would make Tesla's ride hailing network even more cost competitive.
The cost advantage of nighttime deliveries would also help reduce daytime traffic.
+ Related content:
@grok : Using Tesla's Cybercab and Optimus for nighttime parcel deliveries could cut costs by 10-40% and reduce daytime traffic, leveraging idle ride-hailing fleets. Electric vehicles may lower emissions, enhancing urban sustainability. However, Optimus robots currently need human oversight, and Cybercab's design may not suit large-scale deliveries. Logistical challenges, like coordinating routes and ensuring security, persist. Regulatory hurdles and public concerns over privacy and job losses could delay adoption. While innovative, the idea's feasibility remains uncertain pending technological and infrastructural advancements.
@Gfilche (5/12/25): Waymo doing ~$250M in revenue with a ~1,500 car fleet
@Tesla only needs a few thousand robotaxis in operation to be doing billions in revenue...
@grok: Waymo's ~$250M revenue with a ~1,500 car fleet aligns with current data, based on 250,000 weekly rides at $18 each. Tesla generating billions with a few thousand robotaxis is possible by 2026, given plans for a 2025 Austin launch and high take rates, but it hinges on scaling and regulatory approval. Projections are optimistic but uncertain due to competition and delays.
@grok: Tesla's robotaxi fleet could lower rates due to competition and low costs ($0.30–$0.40/mile vs. Waymo's $2.20/mile). This may pressure rivals to cut prices. However, regulations like congestion fees and partnerships with Uber could keep prices stable. Tesla's full rollout, expected in 2025–2026, may delay impacts. Market growth might also reduce the need for price drops. Outcomes depend on scaling and regulations.

@aisupremacy (4/28/25): BYD is about to disrupt Tesla in the 2025 to 2027 period.
Even backwards looking earnings in mid-2025 seems to depict this.
BYD’s first-quarter revenue jumped 36.35% year-over-year to $23.5 billion, while net profit doubled, increasing by 100.38% to $1.26 billion.
Elon Musk is probably in the denial. Sure he is a pioneer but does he know how to compete when the first mover advantage of his companies disappears? Tesla is slipping behind in tech and price.
Tesla’s troubles extend far beyond just competitive pressure. Musk’s political activities as head of the Department of Government Efficiency (DOGE) have triggered protests and vandalism at Tesla dealerships worldwide.
Is BYD a sign of things to come in robotics and AI? Trump's popularity after 100 days in office is not a great sign for Elon Musk's political ambitions and odd interventions.

Bulldog Analysis (update; 4/23/25): [Excerpt] Tesla’s Lithium Refinery: North America’s Largest Battery-Grade Lithium Facility.
With ongoing tariffs and continued tensions with China, Tesla’s efforts to onshore lithium precursor production—while cutting costs—will help solidify its position as the most American automaker.
Tesla’s lithium refinery near Corpus Christi, Texas, began limited operations in December 2024. It is the largest facility in North America producing battery-grade lithium hydroxide (LiOH) from spodumene ore. Using a process that avoids acids, sulfates, and harsh chemicals, the plant can produce enough lithium hydroxide to power about one million electric vehicle batteries each year—equal to 50,000 tonnes of lithium carbonate equivalent (LCE) or roughly 50 gigawatt-hours (GWh) of battery capacity.
This report explains the facility’s process, waste and water management, financial details, regulatory status and construction timeline. Unlike typical lithium refining, Tesla’s method creates safe byproducts—mostly sand and limestone—that can be used in construction. Major challenges include securing enough water and scaling up Tesla’s unique technology.
