Changelog

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_images for 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.
• webp is the default output format.
• No transparent background — keep using gpt-image-1.5 for transparent PNGs.
• Pricing per output image: low 4 / medium 9 / high 23 / auto 23, multiplied by number_of_images. See Credit costs and the gpt-image-2 reference.

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 through PENDING → UPLOADING → TRAINING → READY (or FAILED). Optional webhookUrl fires on terminal state.
• DELETE /v2/loras/:id — soft-archive.
• POST /v2/images/generate — new model flux-lora: pass loraId + 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 when audio is omitted.
• POST /v2/videos/generate — wan-2.7-r2v: reference-to-video. Up to 5 reference_images and/or 5 reference_videos, plus shot_type for 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 when duration is 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.
