Stage the losing battle.

“Cinematic film still, frame from a deadpan live-action comedy: a small waist-high tyrannosaur with realistic matte scaled skin stands beside an ordinary double bed, pinching one corner of a pale fitted sheet in its tiny forelimbs, while the opposite corner has sprung off the mattress and lies bunched in the middle of the bed; a single domestic chore in a plain bedroom, no destruction, no threatening pose. Eye-level 35mm medium-wide film still, slightly off-center blocking, plausible window light through thin curtains, lived-in bedroom with worn furniture, the defeated pause immediately after the corner escaped. Ordinary animal anatomy with clear limb contact on the sheet, documentary realism, restrained grading, no cartoon, illustration, CGI gloss, miniature look, legible text, signage or letterbox bars.”

What it does best

Every line here comes from our own runs of FLUX.2 Pro.

  • Does what you typed

    Exact label, a natural hand and a soft café behind it, in both cold brew runs. It added nothing we didn't ask for. Three of the other eight did.

    Label exact in 2 of 2 runs, nothing added, in our nine-model test

  • Quick turnaround

    8.9 seconds on average in the shootout. Only Recraft was faster. On our product briefs it averaged 8.0 seconds an image.

    8.9 s average, 2nd fastest of 9 in our shootout

  • Options, not copies

    7 of 9 product shots were good enough to hand to a client. Unlike Flare, its runs of the same brief came out different from each other.

The work

  • Warm the deep.

    A small driftwood campfire burning impossibly on a dark seafloor, ringed with careful stones, its flames sharp and steady in the water, a circle of silver fish gathered around it at even spacing like listeners, firelight rippling up through the water column in caustic ropes, deep blue-black depth beyond, filmic grade, single bold warm subject centered, high contrast, one ember rising as a slow bright bead through the water

    Use prompt
    Time it to the centimeter.

    A bicycle courier caught mid-lean threading the narrow gap between two passing trams at dusk, a single hard shaft of dusty golden light cutting the gap exactly where she rides, coat flaring, tram windows streaking with motion blur on both sides of her sharp figure, sparks from the tram wire above, wide dramatic composition, high contrast, her front tire's reflection sliding on the polished rail

    Use prompt
  • Keep the line open.

    A red telephone booth standing upright on a dark seafloor, its interior lamp still burning warm through the fogged glass, the receiver floating weightless at the end of its coiled cord, silver fish schooling around the roof, marine snow drifting through the light, deep blue-black water, single bold subject centered, high contrast, the cord's coils throwing thin shadows on the glass

    Use prompt
    Choreograph the sparks.

    Two fencers mid-lunge dueling on a vast frozen black lake at night, blades crossed at the instant of impact throwing white sparks that scatter and skate across the mirror ice, their reflections doubled beneath them, breath clouds lit by the sparks, distant shoreline lights tiny on the horizon, wide dramatic composition, high contrast, one spark dying in a long curl between their reflections

    Use prompt
  • Stage the sunken scene.

    A woman in a long red dress standing weightless on the tilted parquet floor of a sunken ballroom, hair and silk lifted upward by the water, rows of gilded mirrors along the walls catching a faint green surface glow, dust and plankton drifting like slow snow, deep teal darkness above, single centered figure, high contrast, the dress hem curling like flame in the current

    Use prompt
    Monolith at first light.

    A black monolith tower rising from a fog plain, one vertical gesture filling the frame, first light striking only its top edge in a hard line of gold, base dissolving into mist, monumental scale, single dominant light source, stark silhouette legible at thumbnail size, graded granite and dawn gold

    Use prompt
  • Profile in red rim light.

    A shaved-headed woman in strict profile against pure black, a single scarlet rim light tracing forehead, nose, and jaw, gold thread earring catching the light, everything else falling to shadow, decisive graphic silhouette legible at thumbnail size, graded crimson and black

    Use prompt
    Mood on command.

    An empty laundromat at 3am, banks of fluorescent light humming over checkerboard tile, one dryer's porthole spinning a warm blur, rain-streaked window black behind the machines, the fluorescent night mood carrying the entire frame, minimal subject, decisive green-white grade

    Use prompt
  • Detail that survives 4K.

    A jewel beetle's armored shell filling the frame, iridescent micro-facets and pitted chitin razor sharp from edge to edge, one leg joint showing bristle rows and articulation, a single droplet of water magnifying the texture beneath it, hard side light raking the relief, layered micro-detail with no soft edges, graded emerald and bronze

    Use prompt
  • Worlds that behave.

    A monumental shelf cloud rolling over flat wheat fields, rain curtain visible under its dark leading edge, late sun still striking the foreground gold, a single small farmhouse with one lit window for scale, wheat bending in the outflow wind, believable storm light behavior, anamorphic composition, graded gold under slate

    Use prompt
    Style is a dial.

    A small fishing harbor at low tide, hulls leaning in the mud, masts drawn in three confident strokes, pigment blooming wet-into-wet in the sky, paper texture visible, the harbor fully legible through the looseness, restrained storm-grey palette with one red hull, style fully committed

    Use prompt
  • Direct whole scenes.

    A flyover shot skimming toward a monastery carved into a red canyon wall, prayer flags streaming in the wind of the pass, a switchback stair with two climbing figures for scale, morning fog pouring through the canyon floor below, motion energy in the camera's forward drift, anamorphic wide, graded rust and pale blue

Prompt tips

What changed FLUX.2 Pro's results in our runs.

  1. Say where the light comes from

    Describing the shape light makes on a face drew a neon line across it in 4 of 8 runs. Naming the source fixed it in 4 of 4.

    a single scarlet backlight from behind her, outlining the edge of her profile
  2. Put exact words in quotes

    Quoted text came back letter for letter on every label and poster we gave it.

    the label printed with "NORTH PIER COLD BREW"
  3. Describe what the lens does

    Naming a 24mm lens changed almost nothing in four runs. Describe the effect you want instead.

    nose close to the camera, ear small and far away
