Enterprise AI tech stack

Explore model providers, data infrastructure, evaluation, orchestration, and governance. See the providers named in covered disclosures and the layers those sources leave unknown.

Reviewed coverage sample · source reviews to (UTC)

Real public-source records, manually reviewed. This is a dated snapshot, not a continuous live feed or a representative market survey.

Dated AI adoption evidence

Source reviews 2026-09-10 to 2026-10-15 · 3 distinct companies in the selected model-provider sample.

Each company counts once per provider. Shares can total more than 100% because companies can disclose multiple providers.

Layers in a generative AI tech stack

Model providers supply AI processing. Retrieval and data layers help make relevant information available. Orchestration connects steps, evaluation tests behavior, and governance defines controls and accountability. A disclosure can name a service without revealing the whole architecture.

Observed enterprise LLM providers

Provider counts describe companies naming AI providers in our reviewed sources. The model-provider layer does not identify every model version, routing decision, or workload. Multiple providers can be listed for the same company.

What the map cannot reconstruct

A vendor name alone rarely identifies the internal orchestration framework or governance process. Empty layers are coverage gaps, not a claim that those functions are absent. The monthly chart currently contains one coverage snapshot and does not establish a growth trend.

What the evidence can tell you

A public job board supports an ATS observation. A subprocessor disclosure identifies a provider that may process data for particular services. A vendor customer story describes a published relationship. These sources have different scopes and are labeled separately.

Counts cover the records on these pages, not the whole market. No observation in our covered sources does not mean a company does not use a vendor. Source recency and unresolved conflicts affect confidence; observations do not establish spend, renewal timing, or customer churn.
