Nano Banana 2, Flux, and Midjourney can all produce a highly realistic-looking portrait. The question that actually matters for a photo of yourself isn't which one renders skin texture best — it's which one has any reference to your actual face at all. Only one of the three does, by design.
This lays out what each system is, how they're accessed, and where the real difference in realism for a specific person comes from.
Generate identity-locked portraits with Nano Banana 2 on the AI headshots page.
- For a photo of a specific person — you — Nano Banana 2 inside Pose is the strongest of the three, because it's the only one built around identity lock: it reads your face from an uploaded selfie and preserves it in the output.
- Flux and Midjourney, used standalone, generate photorealistic images from a text prompt with no reference to a real person's face — the result is a plausible, realistic-looking stranger, not you.
- Flux Kontext also runs natively inside Pose, where it's used from the same uploaded selfie for full-body and lifestyle framing — so within Pose, both Nano Banana 2 and Flux Kontext are identity-preserving; used on their own outside Pose, standalone Flux is not.
- There is no independently verified numeric realism score across the three — the meaningful difference for a personal portrait is the identity-lock mechanism, not a raw image-quality ranking.
Key terms
Nano Banana 2 is Pose AI's native identity-locked image generation engine. It reads your face from one uploaded selfie — no lengthy training step — and generates new images that preserve your actual facial features across styles, lighting, and settings.
Flux is a family of text-to-image models from Black Forest Labs, known for photorealistic output, accessed standalone via pay-as-you-go API pricing (roughly $0.015 to $0.06 per image depending on the variant). Used on its own, Flux has no identity-lock mechanism — it generates from a text prompt with no reference to a real person's face. Flux Kontext, one variant in that family, also runs natively inside Pose, where it's applied to your uploaded selfie for full-body and lifestyle framing.
Midjourney is a prompt-driven image generator accessed through Discord or its web app, on a $10/month Standard or $30/month Pro subscription. It has no identity input at all — every generation starts from a text description alone, so the resulting person is generic rather than a likeness of anyone specific.
