API Platform: Arrow 1.x retires October 16

QuiverAI scheduled Arrow 1.x API retirement for 08:00 UTC (10:00 Berlin) on October 16, 2026. The affected IDs are arrow-1, arrow-preview, arrow-1.1 and arrow-1.1-max. At the cutoff, they stop serving, disappear from GET /v1/models and return 404 model_not_found. Requests aren't automatically routed to Arrow 2.

The replacement is arrow-2 for SVG generation, vectorization, editing and animation. Native endpoint paths stay the same, but Arrow 2 uses measured token pricing instead of Arrow 1.x's fixed-credit prices.

If your API key allows all models, change the request model to arrow-2. Exact-model Arrow 1.x keys are immutable: create an arrow-2 key, deploy its secret, then revoke the old key after traffic moves. Rotating a key preserves its model authority, so rotation alone won't migrate it.
