API updates and changes.
July 2026 — Kling 3.0 Motion Control (Kuaishou)
Kuaishou's Kling 3.0 Motion Control lands on POST /v2/videos/generate as kling-3.0-motion-control, backed by kwaivgi/kling-v3-motion-control on Replicate and served by the existing replicate-kling provider.
- Transfers motion from a reference
videoonto the character in a referenceimage— both are required inklingParams. - Adds
mode(std720p /pro1080p),character_orientation(imagecaps the clip at 10s,videoat 30s), andkeep_original_soundtoklingParams. - Per-second pricing billed on the reference video's measured duration: 12/s for
std, 21/s forpro. Clips outside the allowed range are rejected before any credits are charged.
See Credit costs for details.
July 2026 — Kling 3.0 Omni (Kuaishou)
Kuaishou's unified Kling model lands on POST /v2/videos/generate as kling-3.0-omni, backed by kwaivgi/kling-v3-omni-video on Replicate and served by the existing replicate-kling provider.
- One model for text-to-video, image-to-video, reference-to-video, and video editing/restyling with native audio.
- Adds
reference_images(up to 7; refer to them in the prompt as<<<image_1>>>, …),reference_video+video_reference_type(featurefor style/camera,basefor editing), andkeep_original_soundtoklingParams.multi_promptis a JSON array of{ prompt, duration }shots (max 6). generate_audiois mutually exclusive withreference_video; when a reference video is set,video_reference_typeis required andreference_imagesis capped at 4.- Same standard/pro/4K modes and per-second pricing as Kling 3.0: 29/s standard, 39/s pro, 72/s 4K (
+audio: 43/s standard, 58/s pro; 4K bills 72/s with or without audio).
See Credit costs for details.
July 2026 — Stable Diffusion 3 & 3.5 (Stability AI)
Stability AI's Stable Diffusion models land on POST /v2/images/generate, backed by the stability-ai/* official models on Replicate and served by the new replicate-stable-diffusion provider.
stable-diffusion-3.5-large: highest-quality SD 3.5 tier. 12 credits per image.stable-diffusion-3.5-large-turbo: near-Large quality in ~4 steps for fast, cheap generation. 8 credits per image.stable-diffusion-3.5-medium: efficient mid-size SD 3.5 model. 7 credits per image.stable-diffusion-3: the original SD 3 Medium MMDiT model with strong prompt adherence and typography. 7 credits per image.- All four share
stableDiffusionParams(aspect_ratio,cfg,steps,seed,negative_prompt,image,prompt_strength,output_format,output_quality) and support image-to-image viaimage.
See Credit costs for details.
July 2026 — Nano Banana 2 Lite (Google)
Google's fastest, most cost-efficient Nano Banana model lands on POST /v2/images/generate as nano-banana-2-lite, backed by google/nano-banana-2-lite on Replicate and served by the same Nano Banana provider.
- Built on Gemini 3.1 Flash Lite Image — text-to-image in roughly 4 seconds, ideal for prototyping and high-volume workflows.
- Outputs at 1K resolution only (no
resolutionparameter). Supports 14 aspect ratios,jpg/pngoutput, image input, and Google Search / Image Search grounding viananoBananaParams. - Flat pricing: 7 credits per image. See Credit costs.
June 2026 — Happy Horse 1.0 & 1.1 (Alibaba)
Alibaba's Happy Horse video models land on POST /v2/videos/generate, served across both Replicate and Alibaba Cloud (DashScope) with automatic failover. Both bill per second of output by resolution and generate synchronized audio.
happyhorse-1.0: text-to-video and image-to-video (single first-frame image), 720p/1080p, 3–15 s. Pricing: 24/s @720p, 48/s @1080p.happyhorse-1.1: adds reference-to-video — pass up to 9imagesand reference them in the prompt as[Image 1],[Image 2], etc. Stronger motion and character consistency. Pricing: 24/s @720p, 31/s @1080p.- Mode is selected automatically: 1.0 from the presence of
image; 1.1 from the number ofimages(0 = T2V, 1 = I2V, 2–9 = R2V).
See Credit costs for details.
April 2026 — GPT Image 2 (OpenAI)
OpenAI's new SOTA image model lands on POST /v2/images/generate as gpt-image-2, alongside the existing gpt-image-1.5. Backed by openai/gpt-image-2 on Replicate and exposed through the same replicate-gpt-image provider.
- Same dual-mode contract as 1.5: omit
input_imagesfor text-to-image, pass one or more URLs to edit / compose. The model always processes inputs at high fidelity. - New
gptImage2Params.moderation(auto/low) for less restrictive content filtering. webpis the default output format.- No transparent background — keep using
gpt-image-1.5for transparent PNGs. - Pricing per output image: low 4 / medium 9 / high 23 / auto 23, multiplied by
number_of_images. See Credit costs and thegpt-image-2reference.
April 2026 — AI Photos (LoRA training)
A brand-new family of endpoints lets you train a Flux LoRA from 15-30 subject photos and then generate AI photos of that subject from any text prompt.
POST /v2/loras— multipart upload + start training. The API auto-captions every image with a vision model, packages the dataset, and runs the LoRA training. Returns 202 with the new LoRA id.GET /v2/loras— paginated list of your team's LoRAs.GET /v2/loras/:id— single lookup; status transitions throughPENDING → UPLOADING → TRAINING → READY(orFAILED). OptionalwebhookUrlfires on terminal state.DELETE /v2/loras/:id— soft-archive.POST /v2/images/generate— new modelflux-lora: passloraId+ a prompt and the API resolves the trained weights and prepends the trigger word for you. 1-4 outputs per request.
Pricing is flat: 2 credits for create (upload+caption+zip), 255 credits for training, 2 credits per image for inference. See Credit costs → AI Photos and the AI Photos overview.
April 2026 — Wan 2.7
The Wan 2.7 family ships across both Replicate and Alibaba Cloud, with a brand-new video-editing route:
POST /v2/videos/generate—wan-2.7: combined T2V + I2V at 720p/1080p, 2–15 s. New first-and-last-frame (last_frame) and clip-continuation (first_clip) anchors. Audio is auto-generated whenaudiois omitted.POST /v2/videos/generate—wan-2.7-r2v: reference-to-video. Up to 5reference_imagesand/or 5reference_videos, plusshot_typefor multi-shot narratives.POST /v2/videos/edit(NEW) —wan-2.7-videoedit: prompt-driven restyle, outfit swap, and background replacement on existing clips. The route probes input duration via ffprobe whendurationis omitted.
All three are billed per second of output. See Credit costs → Wan 2.7.
April 2026 — Editing endpoints
Four new endpoints for editing existing media, on dedicated routes alongside generation:
POST /v2/images/upscale— Topaz Image Upscale for realistic photos and Clarity Upscaler for creative AI art.POST /v2/images/background-remove— Bria RMBG 2.0 for production-quality alpha mattes and 851-labs for cheap, high-volume jobs.POST /v2/images/edit— Flux Fill Pro for masked inpainting and preset-driven outpainting (mode-switched).POST /v2/videos/upscale— Topaz Video Upscale with up to 4K / 60 fps output and per-second pricing.
