What is FLUX.2 Pro
FLUX.2-Pro is Black Forest Labs’ production-grade, closed-weight visual generative model designed for teams and products that require fast, repeatable, photorealistic image synthesis and robust multi-image editing. It is positioned as the highest-performance tier of the FLUX.2 family: engineered for minimal latency, tight prompt fidelity, and output quality suitable for advertising, product imagery, and other commercial creative workflows. The model emphasizes:
- High-fidelity photorealism (4MP raw outputs available).
- Multi-reference editing (Pro: up to 8 reference images via API).
What makes FLUX.2 Pro distinct
- Production latency & throughput: hosted Pro endpoints trade model internals and runtime stacks to deliver low wall-clock time for generation and edits. Reported Replicate figures show ~6 s generation latency (9 s with an input image) on their hosted Pro endpoint.
- High photoreal fidelity and text/typography improvements: engineered to render readable text and precise layout elements reliably — useful for UI mockups, posters, and in-ad creatives.
- Multi-reference editing: Pro supports combining multiple reference images to preserve identity/style across outputs (Replicate’s Pro listing indicates support for up to eight reference images; the FLUX.2 family docs describe up to 10 references for some variants). Use the Pro counts when integrating with the hosted Pro endpoint.
- Native high resolution: FLUX.2 is capable of multi-megapixel outputs (advertised up to 4MP native), while production usage often targets a 1–2MP operational envelope for cost/latency balance.
How FLUX.2-Pro compares with contemporaries
- Nano Banana Pro (Google / internal name of a competitor) — Nano Banana Pro and FLUX.2-Pro compete closely on photoreal fidelity. Reviewers note stylistic differences (composition and color handling), and FLUX.2’s strengths in typography and multi-reference consistency are a distinguishing point.
- Midjourney / Runway / Qwen-Image / Hunyuan Image — independent comparisons put FLUX.2 family in a competitive band: higher win-rates on launch comparisons for many text→image and editing tasks, while commercial SaaS products may still excel in certain stylistic pipelines or user tooling. Choose by the desired fidelity/latency/style trade-offs.

Step 2: Send Requests to Flux.2 pro API
Select the “flux-2-pro ”endpoint to send the API request and set the request body. The request method and request body are obtained from our website API doc. Our website also provides Apifox test for your convenience. Replace <YOUR_API_KEY> with your actual CometAPI key from your account. base url is flux generate image(https://api.cometapi.com/flux/v1/flux-2-pro)
Insert your question or request into the content field—this is what the model will respond to . Process the API response to get the generated answer.
Step 3: Retrieve and Verify Results
After generation, you can use the /flux/v1/get_result endpoint to query generated images or monitor process status.. After processing, the API responds with the task status and output data.
