Does Tesla sell their technology?

I'm curious, does Tesla actually sell their cutting-edge technology to other companies or do they keep it all in-house for their own products? It's a well-known fact that Tesla is at the forefront of electric vehicle and renewable energy technology, but I'm wondering if they also monetize their innovations by licensing or selling their technology to other firms. I'm interested in understanding if this is a viable revenue stream for Tesla, or if they prioritize keeping their technological advancements exclusive to their own brand.
