Can I use the FLUX.2 API on Kunavo today?

Not yet. FLUX.2 [pro] and [flex] (plus their edit variants) are in Kunavo's catalog but not enabled — Black Forest Labs' own list price ($0.03 per 1K image for [pro]) equals wholesale cost, so Kunavo can't serve it below official list. The live text-to-image models on the same OpenAI-style /v1/images/generations endpoint are Nano Banana (~$0.027/image) and GPT-Image-2 (~$0.0633/image, ~50% under OpenAI list).

What is the best FLUX.2 API alternative?

Nano Banana (~$0.027/image) is the closest live alternative for photoreal generation at scale, and GPT-Image-2 leads on prompt fidelity and text-in-image. Both run on Kunavo's OpenAI-compatible /v1/images/generations endpoint, with edit variants on /v1/images/edits.

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

Q: What is the FLUX.2 API?

FLUX.2 is Black Forest Labs' second-generation image model family — FLUX.2 [pro] for top quality and FLUX.2 [flex] for adjustable speed/quality — the successor to FLUX.1 and FLUX Kontext. The FLUX.2 API generates and edits images from text prompts programmatically.

Q: How much does the FLUX.2 API cost?

Black Forest Labs lists FLUX.2 [pro] around $0.03 per 1K image ($0.045 at 2K) — already one of the most aggressive first-party prices. If you only need FLUX, going to BFL direct is the honest recommendation; Kunavo's live alternatives start at ~$0.027/image (Nano Banana) on one multi-modality key.

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.

Availability note. FLUX.2 is in Kunavo's catalog (pro, flex, and both edit variants) but not currently enabled. Black Forest Labs' own list — $0.03 per 1K image for [pro] — equals wholesale cost, so there's no room to serve it under official, and Kunavo only lists models it can price transparently below list. The live image models are Nano Banana and GPT-Image-2 on the same OpenAI-style endpoint.

FLUX.2 API pricing

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

Model	1K image	2K image	On Kunavo
FLUX.2 [pro] (BFL)	$0.03	$0.045	Roadmap — not enabled
Nano Banana (Google)	~$0.027 per image		Live
GPT-Image-2 (OpenAI)	~$0.0633 flat (1K/2K/4K)		Live, ~50% under list

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:

text_to_image.py

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.

FAQ

What is the FLUX.2 API?

Black Forest Labs' second-generation image model family ([pro], [flex] + edit variants), successor to FLUX.1 and FLUX Kontext.

Can I use FLUX.2 on Kunavo today?

Not yet — BFL's own $0.03 list leaves no room to serve it under official. Use Nano Banana or GPT-Image-2 on the same endpoint today.

How much does the FLUX.2 API cost?

$0.03 per 1K image at BFL's list for [pro] ($0.045 at 2K); the [flex] tier trades speed for cost. Kunavo's live alternatives start at ~$0.027/image.

What happened to FLUX Kontext?

Kontext was FLUX.1's editing line; FLUX.2 folds generation and editing into one family. On Kunavo, image editing is live today via /v1/images/edits with Nano Banana Edit and GPT-Image-2 Edit.
