It's just training a very small LoRA you can merge back into the base model, so it should retain the context window!

It was a fun exercise recently to just open up a completely blank file and write an RL agent from scratch, without looking at any of my prior code. There is a point of scale where rewriting things from scratch is a bad idea, but it is a blessing when you can! By “from scratch” I

Simulation and synthetic data help AVs train for rare events—like a helicopter landing on the road. Safety starts in a virtual space. Porsche uses high-fidelity simulation to test what’s too rare or risky to capture in the real world.

Why the shift?
Because real-world driving is too complex to pre-program. Data is the new engine. Billions of kilometers + labeled data + edge cases = safer autonomous vehicles. “We’ve moved away from the rules and handwritten components… to a data-centric approach,” Brian
