Lightning v3.1

lightning_v3.1 will be retired on Nov 30, 2026 (18:30 UTC). Move to lightning_v3.1_pro before then.

After retirement, requests with "model": "lightning_v3.1" or no model will be served by lightning_v3.1_pro, so the voice and sound may change. The legacy /waves/v1/lightning-v3.1/ routes will be retired, and voice clones made on lightning-v3.1 will stop working.

See Deprecation notices for the migration steps.
