Normalized SVI
What is normalized svi?
The sourc Value Index (normalised) rates every entity from 0 to 100 within its domain — how much capability it delivers per dollar compared to peers. 100 means the highest value in the category. The formula differs by entity type: for LLMs, it combines benchmark performance with context window size divided by price. For tools and SaaS, it uses integration density divided by subscription cost. Full formula at /methodology.
Why it matters
The sourc Value Index answers a question that no other data source currently answers: across all tracked entities, who delivers the most capability per dollar? The normalised version (0–100) makes cross-domain comparison possible — you can compare an LLM's value against a tool's value against a SaaS product's value. The formula is public at /methodology. The inputs are verified. The output updates as the market moves.

How sourc.dev tracks this
sourc.dev verifies normalized svi 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.

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 normalized svi 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.
