Changelog

Customer-facing changes to the Seldon API, Functions and these docs.

October 13, 2026

Waitlist. Sign up creates an account and adds it to the waitlist. New accounts see that a new version is coming soon and do not get a workspace yet. Existing customers can log in.

Documentation. These docs replace the single quickstart page: a 5-minute quickstart, a Functions tutorial, guides, concepts and reference.
Base URL. SELDON_BASE_URL now includes /v1 everywhere it is shown, matching what OpenAI-compatible SDKs expect. If you exported the origin without /v1, add it.
Functions comparison reports. New optimization runs compare up to three executable pipelines with your original call. You choose which to activate; the report no longer blocks activation on quality, cost or latency thresholds.
Functions output allowances. New compilations size each call's output allowance from the selected endpoint. New revisions reserve up to $10 per call; earlier revisions keep $1.

Editable evaluation. Each function has one Evaluation card with optional plain-language Edit and inline Test, and imports of up to 400 examples.

Durable optimization. Runs have a fixed two-hour deadline, survive restarts without repeating uncertain provider calls, and show live progress, ETA and spending.

Sign-up paused. New account creation is closed while we prepare the next version. Existing customers can log in.

Functions first. Automatic discovery from gateway traffic was retired. You choose which calls to optimize in Functions.
