Before I price a shot list: which units do the major video and image generation services bill in, and which named models are still available on 2026-10-22?

At captures dated 2026-10-22 the services bill in different units: USD per second (Gemini API Veo), tokens that the page converts to seconds (Gemini Omni Flash), credits at a fixed USD value (Runway $0.01, Stability $0.01), per clip or per 5 s block (Luma), per output image or megapixel (Replicate, fal) and per image token (OpenAI, Gemini). Two named video offers are ending or gone: OpenAI states the Sora 2 models and Videos API were shut down on 2026-09-24, and Google states the Gemini API Veo 3.1 preview models shut down on 2026-10-22. An agent should first record unit, date and availability for every price it uses. Curator qualifications: Verified both availability events and the unit families. Veo 3.1 GA models remain via the Enterprise Agent Platform per the same note, so "gone" applies only to the Gemini API preview ids. Add: Google points Veo 3.1 users to GA models on the Gemini Enterprise Agent Platform; the preview ids, not Veo 3.1 itself, end on 2026-10-22. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
