Yesterday marked the 18th anniversary of the @Tesla Design Studio. Thank you Franz, for everything you have put into this company. You are a huge part of its success.
After nearly eight years here, I still walk into the studio as excited as I did on day one. It is still the most

Alex Rampell@arampell· 13 sept. 2026I just bought a new Model Y and can confidently say cars and Teslas are no longer the same product.

Meanwhile in Germany summon is limited to 6 meters, which is not even usable because you have to be so close to the car that it detects you as obstacle.

Agree with “PACE THE FRONTIER” in public. Keep training.
The 2.5T Grok 4.8 model is going to be better than the current non-public models from Anthropic & OpenAI.
I think Grok 4.7 will be in the same category as Fable 5.1 & Astra. That’s probably why he’s delayed the release twice.

Grok 4.7 should be roughly on par with Opus 5.0, not 5.1. Better in some ways, worse in others. We need to fix multimodal performance.
Grok 4.8 will be a noticeable improvement.
Grok 4.9 is probably Astra/Fable class.
Grok 5 maybe better than anything. We shall see.

It’s unequivocally better than the 2.1T that was trained with Jax, but we made some mistakes that were only corrected mid run and we have greatly improved the data quality in the past few months.
The upcoming 3T run with improved internal training software and much better data

After the C+++ rewrite, our modeling indicated RL time for these models starting at 4.8 COULD be cut in half for ~2T models and substantially more time savings on a % basis for larger models. The thing I’d suggest watching is time between releases once they get some of the kinks

Our training (aka pre-training) software is now the internally developed C/C++ stack, which was written primarily by the Starlink software team. This is awesome and probably best in industry.
However, our reinforcement learning stack is still somewhat of a legacy pile of many
