Cost advantage
| Cost Dimension | Description |
|---|---|
| Free version | Open source model is free to use (Dev/Klein version), supports local deployment and community resources |
| Subscription version | Pro/Flex version pays as you go through API, suitable for users who need high-performance inference in the cloud |
| Enterprise Edition | The Enterprise Edition provides privatized deployment, batch inference and dedicated support, with on-demand quotation |
Flux 2 provides an open source version for free self-deployment, and can be used at zero cost for teams with GPU resources. The cloud API solution is billed by volume, and the cost is controllable with the same output quality. The dual-track model of open source + cloud services allows users to flexibly choose according to actual needs.
Main functions
- Multi-picture reference generation: Supports simultaneous reference to multiple reference images to generate new images while maintaining subject consistency.
- 4MP high-resolution output: Directly generate images with a resolution of up to 4MP (approximately 2048×2048) without post-amplification.
- Complex Text Rendering: Accurately render Chinese and English text in generated images, supporting multi-line text and different font styles.
- Multi-version model selection: Pro/Flex/Dev/Klein four versions cover different usage scenarios.
- Image Editing and Repair: Supports partial image editing and content repair based on text commands.
Model and version evolution
| Version | Date | Key Changes |
|---|---|---|
| Latest version (v1.0 public beta version) | 2026-07-14 | Multi-image reference fusion, 4MP high-resolution output, complex text rendering |
| Previous version (v0.9) | 2026-06 | Early internal beta version, basic image generation |
Iterative directions for the model include more efficient inference speed, more accurate text rendering, and richer style control.
Technical advantages
- Multi-image reference fusion architecture: Through innovative attention mechanism design, the visual features of multiple reference images are processed simultaneously and merged into unified generation conditions.
- High-resolution native generation: Using efficient network structure design, generation training is performed directly on the native resolution.
- Text Rendering Enhancements: Achieve precise text positioning and rendering through the collaborative optimization of the text encoder and spatial guidance mechanism.
- Multi-version optimization strategy: Targeted quantification and pruning optimization of the model according to different usage scenarios.
How to use
| Entrance | How to use |
|---|---|
| Web client (BFL platform) | Visit bfl.ai → Select Flux 2 → Enter prompt word → Upload reference image (optional) → Generate and download |
| Local deployment | Download model from HuggingFace/GitHub → Configure environment → Run inference |
| API | Get API Key → Call inference interface → Get generated results |
The open source version runs locally and the cloud API does not require a GPU. Typical process: select version → enter prompt word → configure parameters → generate → filter results.
Product Pricing
| Package | Price | Contents |
|---|---|---|
| Free version | $0 | Free download and use of open source model (Dev/Klein), you need to bring your own GPU |
| Professional Edition | — | Cloud API pay-as-you-go (Pro/Flex), including high-priority inference |
| Enterprise Edition | — | Private deployment + batch inference + dedicated technical support |
The open source version can be used at zero cost but requires your own GPU resources. The cloud API is suitable for users who don't have a GPU or need high-performance inference.
Application scenarios
