DEVELOPERS
The API is coming.
The models powering Spades products will be available as an API. Per-request pricing. No provisioning. You send documents. You get structured output back. The first endpoint exposes the adaptive concept graph Phi builds from uploaded material — the same model that runs its learning sessions. More follows as products ship.
THE ENDPOINTS
Creates an adaptive learning session from uploaded document content. Returns a session ID and the structured concept graph the model extracted from the source material.
Submits a user response to the current session prompt. Returns a confidence score for the relevant concept, an updated retention schedule, and the next prompt.
Returns the current gap map for a session — concepts ranked by retention risk, time since last review, and model confidence. Designed for third-party spaced repetition integrations.
HOW IT'S BILLED
Pricing is provisional and will change before launch. Numbers here are illustrative of the model, not a commitment.
RESEARCH & WRITING
Development of Spades products is documented publicly. Build logs, architecture decisions, and model evaluations are published as they happen — not polished retrospectives. The writing is the research record.
REQUEST API ACCESS
The API is not open yet. Leave your email and you will be first to know when access opens — and first to get a free tier allocation.
No spam. One email when access opens.
Built by an engineer, for engineers.
