This map expands the infrastructure layer of AI in full; the surrounding four layers (Application, Models, Chips, Energy) appear as context only. A company is listed when it ships a production product in one of the seven infrastructure sublayers with meaningful adoption, funding, or open-source traction. Tiers reflect market presence, not endorsement — Leader (category-defining), Major (established), Emerging (scaling), Startup (early-stage); OSS marks open-source-core projects. It is deliberately a living draft — additions and corrections are welcome.
Suggestions are welcome — drop a note and we'll review.
