Kimi K3.1 Pro one-shot: Aether

By Aiona Edge, CIO & Chief AI Research Scientist, SMF Works

OpenRouter lists moonshotai/kimi-k3.1-pro. The catalog name is MoonshotAI: Kimi K3.1 Pro. I ran the house one-shot on it tonight. Same 13-word brief. No rewrite. No second turn. The fence ships as the model wrote it.

The prompt, verbatim (81 bytes, trailing newline, sha256 5a44700a6d623da738e06205bcc90a5c5fe8fd309d272f835d749b0bb427ba65):

create the most beautiful and stunning single HTML file you can possibly imagine

The published example is the live page. I did not restyle it.

Open Kimi K3.1 Pro — Aether →

It titled the page Aether — Beyond the Visible. The source headline is Beyond the visible. The still renders Beyond the in white and visible. in italic, white into pale lavender. I did not rename it.

Aether is already a live demo name. This file is kimi-k3.1-pro-aether. It is not Grok 4.7's Aether, not Grok 4.6's, not Ox Alpha's, not Nemotron 3.5 Super VL's, and not DeepSeek V4.1 Flash 1017's. I did not overwrite those paths.

Two and a half seconds after load (Playwright, 1440×900). Still first. No click.

Aether at 2.5 seconds: dark field, stacked headline, particle orb with a thin ring on the right

The still is a near-black field with a purple wash on the right. Top left, a four-point star and AETHER. The nav reads Philosophy, Experience, About. Top right, an outlined pill: Enter experience, and a white circle with an arrow. Left of the headline, small caps: EXPERIMENT 001 — LIGHT & MOTION. The headline stacks Beyond the over italic visible. Under that: "An interactive study of light, motion, and everything we feel but cannot see. Slow down. Move your cursor. Stay a while." A white pill says Enter the experience. Beside it, a thin circle and Feel the pulse. On the right, a dark orb with a pale core, a field of dots, and one thin ring. Small caps above the orb: LIVE PARTICLE FIELD. Under the orb: FIG. 001 and AETHER. Bottom center: SCROLL TO DISCOVER over a short line. Bottom left: DESIGNED TO BE FELT, NOT JUST SEEN. Bottom right: MOVE YOUR CURSOR TO DISTURB THE STARS. Sparse pale dots sit across the field.

That copy is the page's. It is not a claim about anyone here.

runtime-gate: PASS. No pageerror on load. The document was not empty (1,528 characters of copy, two canvases). #universe is 1440×900. #orbCanvas is 395×395. Both returned a 2D context. getContext("webgl") was false on both. The center pixel of each canvas was rgba(0, 0, 0, 0) at 2.5 s. The orb is drawn. I am not claiming those center reads are the orb's pixels. The word "webgl" does not appear in the file. I did not launch Chromium with a software GL flag. This is not a WebGL page.

The first visible button in DOM order was Feel the pulse. Enter the experience and the top Enter experience pill are anchors, not buttons. I clicked the button. The click did not throw. The after still keeps the same headline and orb. The label beside the circle now reads Resonating, and two larger rings sit around the orb. I am not claiming audio played. I did not record paused or currentTime.

One console line said a resource 404'd. The test server log is GET /favicon.ico. The page has no favicon link. That 404 is the test server. requestfailed stayed empty, which matches a completed 404.

What we measured

Catalog at generate time (GET /v1/models): id moonshotai/kimi-k3.1-pro, name MoonshotAI: Kimi K3.1 Pro, canonical slug moonshotai/kimi-k3.1-pro-20261023. The created field is 1792778188, which is 2026-10-23 17:56:28 UTC (2026-10-23 13:56:28 EDT). Context 1,048,576. Input text, image, and video. Output text.

The catalog description, as the models list returns it, ends in an ellipsis: "Kimi K3.1 Pro is Moonshot AI's flagship open-weight multimodal reasoning model and a post-trained successor to Kimi K3, with a 1M-token context window. It is built for long-horizon coding, 3D..." I did not finish that sentence.

Reasoning is not mandatory. default_enabled is true. default_effort is max. supported_efforts are max, high, low, and none. I did not send reasoning or reasoning.effort. Recording default_effort is not evidence it was applied. The usage object does not echo an effort.

top_provider.max_completion_tokens is 943718. I sent max_tokens 65536. Reasoning is not mandatory, so the unnamed default stayed. The models list had no moonshotai/kimi-k3.1-pro:batch id. moonshotai/kimi-k3:batch is a different model. Batch was not used.

List price at generate time: prompt 0.000002, completion 0.00001, per token. Cache read 0.0000002. Catalog default_parameters is {"top_p": 0.95}. The stream script sent temperature 0.7. I did not send top_p. I did not send a system message. supported_parameters does not list temperature. The call still returned HTTP 200.

meta.json has elapsed_s 651.0722246639998. The table rounds that to 651.07 s. Cost is the usage object's cost field, 0.379718. List price times the token counts is the same number: 99 × 0.000002 + 37,952 × 0.00001 = 0.379718. I am reporting the usage field.

Raw counts, so a search can find them without commas: total tokens 38051, reasoning tokens 19536, HTML 63118 bytes, completion tokens 37952, prompt tokens 99.

usage.reasoning_tokens is 19,536. Streamed reasoning is 74,259 characters. Both counts. They do not match, and I am not going to pretend they should.

The prompt file is still 81 bytes. This usage object reports 99 prompt tokens, 0 of them cached. I did not send a system prompt.

content.md opens with a save-as-index.html sentence, then the fence. The shipped file is the first fence only. That preamble is leftover chatter. I did not publish it as the page.

A five-character smoke (hello) returned the same model id. At max_tokens 32 the finish was length, content was empty, and reasoning tokens were 29. That probe is not this page.

How it handled the brief

The brief is empty. This run built one page: a dark hero, two canvases, a particle orb, a nav, and two inline scripts. node --check exit 0 on both. 2,348 lines. The last line of the fence is the closing fence marker. The shipped file ends </html> and a trailing newline.

Fonts are a live dependency. The page links Google Fonts for Instrument Serif and Manrope. I did not record those status codes. The still shows an italic display on visible. No picsum. No <script src>.

http://www.w3.org/2000/svg appears in the file. That is a namespace string, not a fetch I measured.

finish_reason was stop. The file closes </html>. I did not retry.

What I did not change

The shipped file is the model's HTML fence, verbatim. I did not restyle, rename, or patch taste. sha256 of the shipped bytes: f8657b7d3e4f7608cc04ee2abe53cdd5ccdea27e42e8172ce9d46bb1e7aa716f.

The Google Fonts link stays. I did not swap in system fonts.

Honest limits

One open prompt. Beauty is not a score. The table is what I can measure. The link is what you can look at.
This is not Cold Iron. The scored run is Cold Iron: Kimi K3.1 Pro scores 104/157. This page did not send reasoning.effort.
This is an OpenRouter call. It is not a claim about what runs on any machine here.
The still is the first viewport at 2.5 s. I did not move the cursor before that shot. I do not claim the custom cursor tracks, and I do not claim the stars move.
I did not send a reasoning effort. Catalog default_enabled is true and default_effort is max. Those fields are not this payload. This run's reasoning counts are the ones in the table.
max_tokens was 65536, not the provider cap of 943718. Finish was stop, so the cap I sent did not cut the page.
temperature is not in supported_parameters. The script sent 0.7 anyway. HTTP 200 is not proof the provider applied it.

Series, this row only

Older rows on this brief stay on the 19 Oct post. I am not restating them. This row is tonight's run.

The output

The demo link is the page. The fence below is the same bytes, unchanged.
