LAUNCH ALLOWANCE

Semantic retrieval

Prototype and low-volume vector storage and query capacity.

Current limit: 30M queried vector dimensions/month and 5M stored vector dimensions.
Expected light use: A small public-content index supporting prototype or low-volume semantic retrieval.
What consumes it: Stored vector dimensions and queried vector dimensions across the account.
Fallback: Keyword search, D1 metadata filters, and curated navigation.
Paid successor: Vectorize paid usage or approved vector adapter
Commercial use: Commercial use permitted.
Data warning: Embeddings may reveal source semantics; classify content before indexing.

View all referenced allowances

Semantic retrieval: 30M queried vector dimensions/month and 5M stored vector dimensions.
Embedding bootstrap: First 200M tokens free for several current models; not a monthly renewal.

Upgrade triggers

vector dimensions — 75%. Review index size and paid successor.
empty-result rate — above 20%. Improve synonyms and content coverage.

Conventional fallback: Keyword search, filters, and curated navigation.

View implementation proof

Decision rationale

The implementation favors semantic HTML, static rendering, typed content, and isolated on-demand routes. Optional AI never controls pricing, eligibility, or emergency routing.

Controls

WCAG 2.2 AA target
Provider-neutral adapters
Usage caps and kill switches
Client-owned production accounts
Conventional fallbacks

Verified evidence

Mock mode runs from a clean clone without paid credentials.
Kill switch and allowance states are typed configuration.
Primary navigation and contact paths remain independent of this module.

Known limitation

External provider allowances and production behavior require owner accounts and deployment-time verification.
