How faithfully the image reflects everything the prompt asked for — objects, attributes, relationships, and intent. The single most important axis for most production use, and what alignment benchmarks (GenEval, DPG-Bench, CLIPScore) try to measure. What each rating means here Strong Reliably produces outputs that match complex, specific prompts — including spatial relationships, counts, and fine detail. Moderate Handles straightforward prompts well, but drops or reinterprets details as requests get longer or more specific. Weak Captures the general idea but frequently ignores or invents elements; expect to fight the prompt. Variable Adherence swings with prompt phrasing, guidance settings, or seed — sometimes precise, sometimes loose.

How convincingly the model renders real-world scenes, lighting, skin, and materials. Distinct from "looks nice" — a model can be highly aesthetic but stylised rather than photoreal. What each rating means here Strong Renders convincing real-world scenes — believable lighting, skin, and materials that hold up to scrutiny. Moderate Looks realistic at a glance but shows tells on close inspection (hands, textures, reflections). Weak Outputs read as obviously synthetic or stylised rather than photographic. Variable Realism depends heavily on the subject and prompt — strong for some scenes, artificial for others.

The breadth of styles a model can produce (illustration, painting, 3D, anime, graphic design) and how well it follows style instructions. A wide ecosystem of fine-tunes/LoRAs effectively extends this axis. What each rating means here Strong Fluently spans many styles (illustration, painting, 3D, anime, graphic design) and follows style direction closely. Moderate Covers common styles competently but has a clear default look it tends to fall back to. Weak Locked to a narrow aesthetic; style instructions have limited effect. Variable Range expands sharply with fine-tunes/LoRAs — base model is narrower than the wider ecosystem.

The ability to render legible, correctly-spelled text inside the image (signs, logos, labels). A long-standing weak spot for diffusion models; newer transformer-backbone models are markedly better. What each rating means here Strong Renders legible, correctly-spelled text — short signs, logos, and labels come out clean. Moderate Manages short words but garbles longer strings, spacing, or unusual fonts. Weak Text is typically misspelled or illegible; treat it as decorative only. Variable Quality drops fast as the string gets longer — fine for a word, unreliable for a sentence.

Getting multi-object scenes right: correct counts, spatial relationships ("A on top of B"), and binding the right attribute to the right object (the "red cube, blue sphere" problem). Measured by GenEval and T2I-CompBench. What each rating means here Strong Gets multi-object scenes right: correct counts, spatial relationships, and the right attribute bound to the right object. Moderate Handles two or three elements but slips on counting, ordering, or attribute binding as scenes grow. Weak Struggles with anything beyond a single subject; objects, counts, and positions blur together. Variable Accuracy depends on scene complexity — dependable for simple layouts, shaky for crowded ones.

The largest / highest-quality native output the model produces before needing upscaling, and the set of aspect ratios it supports well. Matters for hero and print assets. What each rating means here Strong Produces large, high-quality native output across many aspect ratios before any upscaling is needed. Moderate Solid at standard sizes; needs upscaling for hero or print-scale assets. Weak Limited to smaller native outputs; pushing the resolution degrades quality. Variable Usable resolution depends on the host/endpoint and chosen settings rather than the model alone.

How quickly the model produces an image, driven mainly by step count and backbone size. Directly tied to per-image cost on compute-billed hosts and to user-facing latency. What each rating means here Strong Generates images quickly — low step count or a distilled backbone keeps latency and per-image cost down. Moderate Typical generation time; fine for interactive use but not the fastest option. Weak Slow to generate, raising both latency and compute-billed cost per image. Variable Speed scales with step count and resolution — fast in a few-step mode, slow at maximum quality.

Capability ratings are an expert synthesis across benchmarks, community evaluations, and provider documentation. “—” means no profile data for that dimension.
