PixVerse API v2 — Seedance 2.5 across create, create-frames, and create-fusion:

• seedance-2.5 generates 4–30 seconds in one call, double the Seedance 2.0 family's 15. Two qualities, 480p and 720p — no 1080p or 4K.
• Fusion takes up to 50 references in total — 30 images (frame_1_path…frame_30_path), 10 videos (video_1_path…video_10_path), and 10 audio (audio_1_path…audio_10_path), up from 9 + 3 + 3. Reference clips may run 1.8–30.2 seconds each and summed, against the 2.0 family's 2–15.
• Native audio on every generation. The model takes no audio parameter and rejects one, unlike the 2.0 family's toggle.
• Attaching a fusion reference video lowers the per-second rate — 21 credits/sec at 480p and 45 at 720p, against 35 and 75 without — but the reference's own duration is billed on top of the output. A reference only saves credits while it runs shorter than about two-thirds of your output.
• Available on Pro, Premium, and Ultra plans. Aspect ratios 16:9, 4:3, 1:1, 3:4, 9:16, and 21:9.

Runway API v1 — Seedance 2.5 and Seedance 2.0 Mini on POST /videos/create:

• seedance-2-5 generates 4–30 seconds in one call against the Seedance 2.0 family's 15, and accepts duration: 0 for Auto, letting the model choose the length. Auto bills up to the 30-second ceiling and refunds the unused remainder.
• Up to 50 references in total — 30 images (imageAssetId1…imageAssetId30), 10 videos (videoAssetId…videoAssetId10), and 10 audio (audioAssetId1…audioAssetId10), up from 9 + 3 + 3. Prompts go to 15,000 characters against 3,500.
• Cheaper than Seedance 2.0 at 20 credits/second in 480p and 30 in 720p, against a flat 36. Two qualities only, 480p and 720p, with 720p the default.
• New output_format parameter selects the container, mp4 (default) or mov. aspect_ratio additionally accepts auto, letting the model choose the framing.
• An audio reference no longer needs an image or video alongside it, and each audio clip may run 1.8–30 seconds. Reference videos may run up to 31 seconds each.
• In exploreMode the output is capped at 15 seconds, Auto is unavailable, and the combined duration of all reference videos must also stay within 15 seconds. Credits Mode has the full 30-second range.
• seedance-2-mini is the cheapest of the family at 16 credits/second at either resolution, against 29 for seedance-2-fast and 36 for seedance-2. It offers 480p and 720p, and is otherwise identical to seedance-2-fast except that it defaults to 720p rather than 480p and offers no 1080p.
• Reference-video limits corrected for seedance-2, seedance-2-fast, and seedance-2-mini — each clip may run up to 16 seconds, and the previously documented 15-second combined limit does not exist upstream and is no longer enforced.

Dreamina API v1 — new image model, and per-region availability updates:

• New image model seedream-5.0-pro (Image 5.0 Pro) on POST /images, CA region. Tuned for cinematic and text-rich visuals, with up to 6 reference images and three resolution tiers — 1.5k, 2k (default), and 4k. 1.5k is a new tier no other model offers.
• seedance-2.0-mini now runs on US accounts as well as CA on POST /videos. It previously returned "Model seedance-2.0-mini is not available in region US".
• gpt-image-2 now accepts up to 6 reference images, up from 3.
• On US accounts seedance-1.5-pro and seedance-1.0-mini generate at 720p only, and nano-banana is unavailable. All three are unchanged on CA.

PixVerse API v2 — Relax Mode throttling documented, and the cost calculator corrected against PixVerse's live pricing:

• "Unlimited" Relax Mode image generation is throttled. Past a daily volume threshold PixVerse moves the account into a slow queue instead of refusing the request, so generations still succeed and still cost no credits — they just take far longer to come back. The threshold applies per model, so an account throttled on one model keeps running at full speed on every other one. We have seen the ceiling at roughly 300 a day for nano-banana-pro and 500 for gpt-image-2.0, and not yet on the remaining models.
• queue_data is now documented on GET /images, GET /images/{image_id}, GET /videos, and GET /videos/{video_id}. Alongside queue_count, queue_time, and estimated_gen_time it carries slow_queue and reason, where daily_limit_exceeded identifies a throttled account.
• Third-party discounts are per model, not one rate per plan. Pro and Premium get 40% off seedance-2.0, 10% off seedance-2.0-fast, and 45% off seedance-2.0-mini. Ultra gets 64%, 46%, and 67% on those three, 20% off seedance-2.5, and 40% off every other third-party model. A model-specific promotion replaces the plan-wide Ultra discount rather than stacking with it, and the calculator previously applied a flat 40% to everything on Ultra.
• Seedance 2.0 pricing corrected. PixVerse moved the family to a flat per-quality rate — seedance-2.0 costs 20 credits/sec at 480p, 45 at 720p, 90 at 1080p, and 200 at 2160p, seedance-2.0-fast 15 and 30, and seedance-2.0-mini 8 and 18.
• Yearly billing added to the calculator — Pro $288/yr ($24/mo), Premium $576/yr ($48/mo), Ultra $1,788/yr ($149/mo). Monthly credits are unchanged, so a yearly plan is the same generation at 20–25% less. A fourth plan, Team Ultra, prices identically to Ultra and differs only in offering 12 concurrent generations instead of 8.

PixVerse API v2 — Relax Mode queue behaviour documented, and the completion window extended to match:

• Generations now have 3 hours to complete, up from 30 minutes. PixVerse throttles its unlimited Relax Mode models by moving an account into a slow queue rather than refusing the request, and that queue can hold a generation well beyond half an hour — of those running over 5 minutes, half finish within 18 minutes and one in five takes longer than 30. The window now accommodates it. The expiry message reads 180 minutes rather than 30, so match on the status code rather than the text.
• The daily Relax Mode allowance resets at approximately 00:00 UTC. A throttled account is clear again at the start of the next UTC day.
• Throttling is most frequent on nano-banana-2, then nano-banana-pro and gpt-image-2.0. The point at which it starts varies between accounts, so treat the published figures as rough guidance rather than fixed limits.
• If you have several PixVerse accounts configured, selection now takes the requested model into account. Because the allowance is per model, an account throttled on one model stays fast on every other one, so requests are steered towards accounts with nothing already queued on the model you asked for. This can only use headroom that exists — an account pool that is throttled on a model throughout has no spare capacity to find, and the answer there is more accounts or a different model.

Google Flow API v1 — four endpoints failed for part of the day, now fixed:

• POST /videos/upscale, POST /videos/extend, POST /videos/concatenate, and GET /assets/<mediaGenerationId> with ?raw=true returned 400 from roughly 16:30 to 20:45 UTC, after Google retired an endpoint they rely on. Resubmit anything that failed.
• GET /assets/<mediaGenerationId> with ?raw=true now works on uploaded videos as well as generated ones, and supports range requests.

Kling API v1

New multi_shot parameter on POST /videos/text2video, POST /videos/image2video-frames, and POST /videos/omni. Set multi_shot: true and Kling cuts a single ordinary prompt into several shots by itself, choosing where the cuts fall. It is the counterpart to the existing shot_1_prompt and shot_1_duration parameters, which let you storyboard every shot yourself — reach for multi_shot when you want the cuts without planning them. Generating with it costs no extra credits.

Dreamina API v1

seedance-2.5 now generates at 1080p on CA accounts via POST /videos, alongside the existing 480p and 720p. US accounts stay at 480p and 720p. It costs 117 credits a second, and unlike the two lower resolutions the rate is the same whether or not you attach an omni video reference — the reference discount applies at 480p and 720p only.
