A reference shows the model what to follow for one generation. A LoRA teaches a compatible model a reusable version of that subject or style. For most people, references are the basic place to begin. Training a LoRA before testing them can turn a simple job into a small technical hobby that nobody asked for. ## Quick answer **Start with reference images.** Train a LoRA only when references stop giving you enough control, or when you need the same character, product or style across so many images or videos that supplying and correcting references every time becomes impractical. | Question | Reference images | LoRA | | -------------------- | ---------------------------------------------------------------- | --------------------------------------------------------------------- | | What do you provide? | One or more images during generation | A prepared image dataset used for training | | Setup | Immediate | Training, testing and usually retraining | | Easy to change? | Yes, replace or add another reference | Less so; important changes may need new training | | Best suited to | Occasional work, changing scenes and trying different ideas | Repeated subjects or specialised styles across serious production | | Model support | Available in many closed and open models | Limited to compatible models and platforms that allow LoRA loading | | Main risk | The model may copy the wrong detail or drift between generations | A weak dataset can teach the model an averaged or inaccurate identity | ## What does a reference image do? A reference image gives the model visual information when you generate. Depending on the tool, it can guide a face, object, composition or style, and you can replace it whenever you need a different angle, outfit or product version. If the character looks wrong from the side, you can add a stronger side-profile image. If a product changes colour, you can upload the new packaging rather than train everything again. Our [consistent AI character guide](https://theseguysknow.io/nano-banana-consistent-ai-character/) uses a face master, a full-body master and clearly assigned reference roles, which was enough for an image-first workflow without LoRA training. References have moved well beyond basic image copying. Runway says [Gen-4 References](https://help.runwayml.com/hc/en-us/articles/40042718905875-Creating-with-Gen-4-Image-References?ref=theseguysknow.io) can preserve a character across different lighting and locations from one source image. [Midjourney's Edit Model](https://docs.midjourney.com/hc/en-us/articles/32162917505293-Character-Reference?ref=theseguysknow.io) accepts up to four references, while [Seedance 2.5 through Runway](https://help.runwayml.com/hc/en-us/articles/53542207042323-Creating-with-Seedance-2-5?ref=theseguysknow.io) accepts up to 30 images, 10 videos and 10 audio clips. Throwing 50 files at a model is probably not the cure for a badly organised idea, but this is hardly a basic workflow anymore. ## What does a LoRA do? LoRA stands for *Low-Rank Adaptation* \- instead of retraining an entire model, it trains a much smaller set of added weights. [Hugging Face](https://huggingface.co/docs/diffusers/training/lora?ref=theseguysknow.io) describes the method as faster and more memory-efficient than full training, with smaller files that are easier to store and load. The practical result is that the character, product or style becomes something the model has learned, so you do not have to supply the same collection of references every time. Supported workflows can also mix LoRAs, perhaps using one for a character and another for a particular game or illustration style. You still need a clean dataset, suitable captions, training settings and a model that supports the finished LoRA. Compatibility is not automatic across model families, and some web generators will not load a private LoRA. A poor dataset can also teach the inconsistency you wanted to remove, including changing facial proportions or clothing that appears in every generation because it appeared in every training image. ## When are reference images enough? Stick with references for occasional character photos, product concepts, campaign ideas, or a manageable number of video shots. They are also better while the identity or art direction is changing, because a new reference can correct the previous one without another training run. A strong style reference can already move an image toward a particular game, comic or cinematic look. Consider a LoRA when that look is very specific, must remain recognisable across a large body of work and keeps weakening whenever the scene changes. ## When does training a LoRA make sense? A LoRA makes sense once you have proved the character, product, or style with references and know you will use it repeatedly. It becomes more useful across hundreds of outputs, automated production, or a compatible workflow where good reference material still produces identity drift. Video alone is no longer a good enough reason. Current reference-to-video models can carry characters, styles, motion, and audio from supplied material, so test those controls first. If a series still needs constant repairs between shots, a good LoRA can establish a steadier identity before you add the references for each scene. ## Can you use a LoRA and reference images together? Yes. The LoRA can carry the recurring identity or specialised style, while references control the outfit, pose, product angle, room, or composition required for one generation. They solve different parts of the same job, and neither guarantees perfect continuity. Hands can still deform, logos can still mutate, and a trained character can still arrive looking like a suspicious cousin when the model, prompt, or source material is weak. ## Final verdict Use reference images until they give you a clear reason to stop. They are faster, easier to correct, and now strong enough for many serious image and video workflows. Train a LoRA when the same subject or specialised style has become a production asset, you have enough clean material to teach it properly, and your chosen model supports it. For a few AI photos, LoRA training is unnecessary homework. For a recurring character, fixed product line, game world, or long video series, that extra work can start saving more time than it consumes. --- #### Sources Product capabilities checked 4 September 2026. - [Runway: Creating with Gen-4 Image References](https://help.runwayml.com/hc/en-us/articles/40042718905875-Creating-with-Gen-4-Image-References?ref=theseguysknow.io) - [Runway: Creating with Seedance 2.5](https://help.runwayml.com/hc/en-us/articles/53542207042323-Creating-with-Seedance-2-5?ref=theseguysknow.io) - [Midjourney: Edit Model and reference images](https://docs.midjourney.com/hc/en-us/articles/32162917505293-Character-Reference?ref=theseguysknow.io) - [Hugging Face Diffusers: LoRA training](https://huggingface.co/docs/diffusers/training/lora?ref=theseguysknow.io) - [ComfyUI: Troubleshooting model compatibility](https://docs.comfy.org/troubleshooting/model-issues?ref=theseguysknow.io)
