Pick one or more AI specialty areas. For everything you check, you'll see companies known to hire for it, free courses to learn it, the hardware it actually takes to practice hands-on, and free/paid ways to get that hardware without buying it outright.
Step 1
Select as many as you're curious about — everything below unions across your selection, with shared companies/courses/tools shown once.
Step 2
One block per specialty, listing its classes. Hardware requirements vary class by class even within the same specialty (a pure-reading course needs nothing; a hands-on notebook needs a GPU) — so each class shows its own hardware tier, the free/cheap way to get it, and where to buy in if you want to go beyond free.
Step 3
Companies with real, verifiable teams/products across everything you selected above — not a live job-count feed. Click through to each one's own careers page.
