FLUX.2 API — Black Forest Labs' pricing, and the live image models today

FLUX.2 is Black Forest Labs' second-generation image family — FLUX.2 [pro] for maximum quality and FLUX.2 [flex] with adjustable speed/quality, succeeding FLUX.1 and FLUX Kontext. The FLUX.2 API generates and edits images programmatically. This guide covers the family, BFL's pricing, and the live way to run the same workloads on Kunavo today.

FLUX.2 API pricing

Black Forest Labs prices FLUX.2 aggressively — that's the point of the family. Published rates at typical resolutions:

If FLUX.2 is a hard requirement, BFL direct is the honest recommendation. If the requirement is production image generation with one key and one bill across modalities, the live lineup below covers the same use cases.

Text-to-image on Kunavo today

Kunavo exposes image generation through one OpenAI-style endpoint, POST /v1/images/generations (edits via /v1/images/edits). The live models are Nano Banana — the value pick, with Nano Banana Pro for text-in-image — and GPT-Image-2 for prompt fidelity. The request shape is identical to what a FLUX.2 call would be:

import requests

# Live text-to-image on the same OpenAI-style endpoint. Swap the model
# string to FLUX.2 once it's enabled — the request shape is identical.
resp = requests.post(
    "https://api.kunavo.com/v1/images/generations",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={
        "model": "nano-banana",   # live today; FLUX.2 on the roadmap
        "prompt": "editorial product photo of a ceramic mug, morning light",
        "size": "1024x1024",
    },
    timeout=120,
)
print(resp.json()["data"][0]["url"])

FLUX.2 vs the live alternatives

FLUX's reputation is realism and typography control at a low price. On the live lineup, Nano Banana matches the price bracket (~$0.027) with strong photorealism and character consistency, and GPT-Image-2 takes prompt fidelity and text rendering. For the full comparison across Nano Banana, FLUX and Seedream, see the image models shootout and the images docs. When FLUX.2 goes live, adopting it is a one-word change to the model field.
