gemini 3.6 flash vs qwen3-max vs gpt 5.6 sol vs kimi k3

@OfficialLoganK and @GoogleAIStudio recently shipped gemini 3.6 flash – their new workhorse. key facts:

• 17% fewer output tokens than 3.5 flash on the artificial analysis index, up to 65% on deepswe, at a lower price – $1.50/1m in, $7.50/1m out

• step up in coding, knowledge work and computer use (osworld-verified 83.0 vs 78.4); fewer reasoning steps and tool calls per task

• pitched as the efficiency sweet spot for scaling agents, not the frontier

the other side of the ring: @alibaba_qwen's qwen3.8-max-preview, unveiled july 19 at waic. 2.4t params, and in alibaba's own release the team calls it "compatible with leading frontier models, second only to fable 5"

one bets on speed and price, the other on raw capability. so we gave both the same hard job – rebuild a real building in 3d from a single photo

every model run through @aimlapi, our partner platform – one api, all the frontier labs in one place

our test – 3 prompts, single-file html, procedural @threejs via cdn, no assets. the model gets one photo and a spec, and has to return an explorable scene: massing, materials, glazing, interior, orbit, day/dusk:

1. ligar bay bach – nz cantilevered cliffside house, blonde timber + black steel + glass

2. blackwood ridge (the sleeve house) – charred-timber wedge with a raking prow

3. fallingwater – frank lloyd wright's concrete trays over a waterfall

results (summed across all 3 houses):

- cost
#1 qwen3-max – $0 (free preview)
#2 gemini 3.6 flash – $0.61
#3 kimi k3 – $1.07
#4 gpt 5.6 sol – $1.75

- tokens
#1 gpt 5.6 sol – 53,889
# qwen3-max – 65,875
#2 gemini 3.6 flash – 69,486
#4 kimi k3 – 170,803

- lines of code
#1 qwen3-max – 2,753
#2 kimi k3 – 2,793
#3 gpt 5.6 sol – 3,395
#4 gemini 3.6 flash – 3,370

overall: no single winner – kimi builds the best-looking scene, qwen the most detailed one for free and on the fewest lines, gpt the highest fidelity but at ~3x the price, and gemini flash the cheapest that still holds up

so we read the code

qwen3-max – the tidiest file of the four. zero external assets: procedural canvas textures for every surface and hand-written glsl shaders for the waterfall + pool. bakes its own pmrem env map in-scene, lerps day/dusk per-frame, and instances the forest with rejection sampling that carves a clearing around the house. the most economical programmer here – fewest lines, most packed into them

gemini 3.6 flash – leaner, but real three.js underneath: correct cantilevers, red mullions, working massing. the headline is that a flash-tier model writes this at all. 3.5 flash gave you threadbare boxes; 3.6 gives you a building. thinner material and lighting layer than qwen, but no longer reads as a budget model

our take:

• kimi k3 is the top designer of the group – better eye than qwen3.8, best composition and lighting on load

• qwen3.8 is the surprise: error-free, fast, plenty of detail – and it does it on the fewest lines of code. efficient and clean at the same time

• gemini 3.6 flash is the story for the labs – flash models are no longer a cheap tier you settle for. they're starting to compete with the full-size models outright
