Blast radius
What is blast radius?
Blast Radius Score measures how many other tracked entities depend on or integrate with a given entity. OpenAI has the highest Blast Radius Score on sourc.dev — changes to OpenAI's pricing, APIs, or capabilities ripple through dozens of tools, frameworks, and platforms. A high blast radius means high systemic importance. sourc.dev computes this from the verified entity_relations graph.
Why it matters
Blast Radius Score is a sourc.dev proprietary metric. It counts the verified integrations in the entity_relations graph — every certified connection, API partnership, community integration, and available-via relation. OpenAI has the highest blast radius because the most tools, frameworks, and platforms depend on it. A price change from OpenAI cascades further than a price change from any other provider. This is the metric that quantifies systemic importance.

How sourc.dev tracks this
sourc.dev verifies blast radius manually from official provider documentation, API responses, and published specifications. Every data point includes a source URL and verification date. When a value changes, the old value is preserved in the history table and the new value is recorded alongside it. Nothing is overwritten — the full timeline is always available.
sourc.dev verifies this attribute manually from provider documentation. Every data point includes a source URL and verification date. Changes are recorded in the history table — nothing is overwritten.
This attribute is verified periodically against provider documentation. When sourc.dev detects a change, the new value is recorded alongside the old one with full provenance.
Understanding blast radius helps developers make informed decisions when choosing between models and providers. Rather than relying on marketing claims, sourc.dev provides verified, dated, source-linked data so the data decides.
