Typically lower cost. * **`mode: "high"` (default)** — Unchanged highest-fidelity path; recommended when fine detail, prompt adherence, or consistency with complex source content matters. * **Same contract** — Both modes share the same request fields and response format; omit `mode` to keep the existing `high` behavior. ### Endpoint `POST /v1/flux-tools/outpainting-v1` See [Choosing a mode](/flux_tools/flux_outpainting#choosing-a-mode) in the FLUX Outpainting documentation. ## FLUX Virtual Try-On — See Any Garment On Any Person A new FLUX Tools endpoint that applies clothing to a person image while preserving their face and pose — built for interactive, low-latency applications. ### Key Features * **Flexible references** — Single garments, multi-garment outfits, and model-to-model references * **Packshot or on-model** — Accepts both flat-lay garment images and on-model imagery * **Low latency** — Optimized for fitting rooms, social filters, and interactive experiences * **Up to 2MP input** — Larger inputs auto-downscale to \~1MP ### Endpoint `POST /v1/flux-tools/vto-v1` Get started in the [FLUX Virtual Try-On documentation](/flux_tools/flux_vto), or try the [public demo](https://flux-tools.bfl.ai/virtual-try-on). ## FLUX Erase — Remove Anything, Leave No Trace A new FLUX Tools endpoint for clean, prompt-free object removal. Provide an image and a binary mask; the model removes the masked content and reconstructs the scene coherently. ### Key Features * **Broad removal scope** — Objects, people, text, watermarks, and complex compositions * **Coherent reconstruction** — Automatically matches lighting, texture, and background * **Optional edge expansion** — Cleaner results on soft-edged subjects * **No prompt required** — Just an image and a binary mask On a held-out benchmark of 198 object-removal images, FLUX Erase matches or outperforms frontier alternatives at substantially lower cost. ### Endpoint `POST /v1/flux-tools/erase-v1` Get started in the [FLUX Erase documentation](https://docs.bfl.ai/flux_tools/flux_erase), try the [public demo](https://flux-tools.bfl.ai/erase), or read the [announcement](https://bfl.ai/blog/flux-erase-remove-anything-leave-no-trace). ## FLUX Outpainting — Extend Any Image in Any Direction A new FLUX Tools endpoint that extends an image beyond its borders in a single call — no prompt required. ### Key Features * **Natural scene extension** — Carries lighting, texture, depth, and composition past the original frame * **Flexible canvas control** — Direct width / height and reference placement via `reference_offset_x` / `reference_offset_y` * **Up to 4MP output** — Production-ready resolutions for banners, social formats, and aspect-ratio changes * **No prompt needed** — The model continues the existing scene on its own ### Endpoint `POST /v1/flux-tools/outpainting-v1` Get started in the [FLUX Outpainting documentation](/flux_tools/flux_outpainting), try the [public demo](https://flux-tools.bfl.ai/outpainting), or read the [announcement](https://bfl.ai/blog/outpainting-extend-any-image-in-any-direction). ## FLUX.2 \[pro] Speed Upgrade & Preview Endpoint FLUX.2 \[pro] is now approximately **2x faster** across both text-to-image and image editing — with no quality loss and no price change. * **\~2x faster generation** — Across text-to-image and image editing workloads * **No quality loss** — On par with the original across all benchmarks * **No price change** — Faster generation at the same price * **Same API contract** — Drop-in upgrade, no code changes required ### New: `flux-2-pro-preview` Endpoint We're introducing `flux-2-pro-preview`, where our latest FLUX.2 \[pro] improvements land first. This speed upgrade is available now on `flux-2-pro-preview`, and the endpoint will continue to be updated as we ship new capabilities. The existing `flux-2-pro` endpoint remains **unchanged** as a fixed snapshot for workflows that require reproducibility. Learn more in the [Preview Endpoint documentation](/flux_2/flux2_overview#preview-endpoints). ## Webhook Payloads Now Match Polling Responses Webhook payloads are now consistent with polling responses. ### What Changed * Status field now returns `Ready` instead of `SUCCESS` ### Action Required If your webhook handler checks for `SUCCESS` status, update it to check for `Ready` instead. ## FLUX.2 \[flex] Performance Update FLUX.2 \[flex] is now up to **3x faster** while maintaining the same quality. Typography rendering, prompt adherence, and fine-grained control remain unchanged. ## FLUX.2 \[klein] Launch We're excited to announce **FLUX.2 \[klein]** — our fastest model family with **sub-second inference**. ### Key Features * **Sub-second generation** — Real-time image generation for interactive applications * **Two variants** — 4B from (\$0.014 / image) and 9B from (\$0.015 / image) models * **Runs on consumer hardware** — As little as 13GB VRAM required * **Open weights available** — 4B under Apache 2.0, 9B under FLUX Non-Commercial License ### API Endpoints * `flux-2-klein-4b` — Fastest, ideal for high-volume and local deployment * `flux-2-klein-9b` — Balanced quality and speed with 8B Qwen3 text embedder Download open weights from [Hugging Face](https://huggingface.co/black-forest-labs) or get started with the [API documentation](/flux_2/flux2_text_to_image). ## Credit Transfer You can now **transfer credits between organizations** directly from the dashboard. * Navigate to your organization's Credits page * Click "Transfer Credits" to move credits to another organization you own * Credits transfer instantly with full audit logging ## FLUX.2 \[max] Launch Introducing **FLUX.2 \[max]** — our highest quality model with groundbreaking capabilities. ### Key Features * **Maximum quality** — Highest editing consistency, strongest prompt following, and faithful style representation * **Grounding search** — Generate images grounded in real-time information from the web * **Multi-reference editing** — Combine up to 10 input images while maintaining identity * **Vast world knowledge** — Create visuals of current events, real-time weather, or historical moments ### Grounding Search Examples FLUX.2 \[max] can search the web to visualize: * Yesterday's football scores * Real-time weather in any city * Recent news events * Historical moments from specific dates and locations Try it in the [playground](https://playground.bfl.ai) or via the [API](/flux_2/flux2_text_to_image). ## Organizations & Projects We've introduced a new way to organize your teams and work with **Organizations** and **Projects**. ### What's New * **Organizations** - Create organizations to group your projects and team members.
