What each foundation models vendor is built for

Replacing a foundation models tool?
Each comparison ranks alternatives by approved relationship, then capability overlap, and shows the switching effort — tools judged to be complements are excluded.
Foundation Models — questions
Which foundation models providers are there?
We track 5 foundation models vendors, including Claude, Gemini, Grok, OpenAI, Writer. Each has a profile with its capabilities graded core or supported from the vendor's own documentation, and 5 of them have a ranked alternatives comparison.
What do foundation models platforms actually do?
On this shelf the capabilities most vendors are built around are agentic ai / autonomous agents, generative ai (content), agent builder / orchestration, ai assistant / copilot. "Built around" is a core grade — central to what the product is — not merely present on a feature list.
How do I compare foundation models tools?
Start from what the tool is core to rather than a feature count: two vendors can list the same capability while only one is built around it. Each vendor page shows the full record, and the alternatives pages rank by approved relationship, then capability overlap.
Which foundation models companies are the largest?
We do not rank by company size, and deliberately: headcount and funding say nothing about whether a product covers the capability you need. 5 foundation models vendors are listed here in catalog order, each graded on what it is built around. Sort by the capability you are buying for instead — that is what the shelf below is for.
Is there a list of foundation models software?
This page is it: every foundation models product in the catalog, 5 of them carrying a capability record graded from the vendor's own documentation, with the source page linked where one was recorded. It rebuilds from the catalog, so a vendor added tomorrow appears here without anyone editing a list.
