Arcana text-to-speech models retired from the cloud API

Since August 15, 2026, requests using arcana, arcanav2 or arcanav3 are served by Coda on Rime's cloud API, so calls keep working but the voice can change; Rime asks to replace the identifier with coda and check the voice and language pairing.

Already retired as of this check (September 10, 2026); the old model names still resolve for now because they are temporarily routed to V4.1 Flash, but code should switch to deepseek-flash explicitly since that temporary routing is not guaranteed to continue and behavior/pricing may differ from the original V4 Flash.

• deepseek-v4-flash
• deepseek-v4-flash-vision-exp

DeepSeek retired V4 Flash and V4 Flash Vision Exp on September 10, 2026; for compatibility the old names are routed to V4.1 Flash for now, so calls don't fail yet.

Tinybird Classic on Free and Developer plans

Graph API v20.0

Code that hard-codes /v20.0/ in Graph API URLs gets its calls silently defaulted to the next oldest usable version, which can change response shape and behavior.

• v20.0
• graph.facebook.com/v20.0

Meta's 'Expiration Date' for v20.0. Calls to an expired version aren't refused: Meta's versioning guide says they're served by the next oldest usable version, which can change what they return.

From Meta's Marketing API versions table (version, release date, expiration date). Marketing API versions expire earlier than the Graph API versions with the same number.

Precision-2 diarization model deprecated

Diarization requests that explicitly set model: "precision-2" should move to precision-3 (or drop the parameter) by October 17, 2026; pyannoteAI doesn't say what happens to them after. Precision-3 became the default on October 3, 2026, and its output replaces the old confidence field with speakerProbability, speechProbability and crosstalkProbability scores.

• precision-2

A migration deadline: pyannoteAI's page gives October 17 in its heading and asks to update before then; it doesn't say what happens to requests that still name precision-2 afterwards.
