OpenRouter lists deepseek/deepseek-v4.1-flash-1017. The catalog name is DeepSeek: DeepSeek V4.1 Flash 1017. I ran the house one-shot on it this morning. 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
Open DeepSeek V4.1 Flash 1017 — Aether →
It titled the page Aether — A Study in Light & Motion. The headline on the page is Aether. I did not rename it.
That word is already on other live demos. This file is not those files. Prior pieces that use the word: Grok 4.6 AETHER · Grok 4.7 AETHER · Nemotron AETHER · Ox Alpha AETHER. Gemini 4 Argon's page is AETHERIA, a different title. The older snapshot of this family, deepseek/deepseek-v4.1-flash, shipped LUMEN on 10 Sep. I did not overwrite it.
Two and a half seconds after load (Playwright, 1440×900). Still first. No click.
The still is a dark field, not a black frame. Centered, italic, pale lilac-white: Aether. Under it, a thin horizontal rule, then small caps: A STUDY IN LIGHT & MOTION. Near the bottom, faint: MOVE YOUR CURSOR. Curved trails of dots and short streaks in teal, violet, gold, and blue, denser toward the upper right. A soft lighter patch sits behind the word. I do not see a button.
runtime-gate: PASS. No pageerror on load. Document was not empty (two canvases plus 51 characters of copy). #fg is 1440×900. #bg reported 648×405 with a client size of 1440×900. The source calls getContext('2d') on both. Center pixel of the first canvas in that still was rgba(5, 11, 21, 255). I did not launch Chromium with a software GL flag. This is not a WebGL page, and I am not claiming a GPU.
There is no button, no [role=button], and no submit input. The gate records no_primary. I did not click the page to invent one. The hint says move your cursor. I did not move it, so I am not claiming the particles push away.
One console line said a resource 404'd. The test server log is GET /favicon.ico 404. The page has no favicon link. That 404 is the test server, not a script the model asked for. requestfailed stayed empty, which matches a completed 404.
What we measured
Catalog at generate time (GET /v1/models, confirmed on a second fetch): id deepseek/deepseek-v4.1-flash-1017, name DeepSeek: DeepSeek V4.1 Flash 1017. The created field is 1792225624, which is 2026-10-17 04:27:04 EDT. Context 1,048,576. Input text and image. Output text. video_tokens, audio_tokens, and image_tokens are 0.
The catalog description, as the models list returns it, ends in an ellipsis: "DeepSeek V4.1 Flash 1017 is the October 17, 2026 snapshot of DeepSeek V4.1 Flash, served by DeepSeek under the deepseek-flash API model name. V4.1 Flash is a sparse mixture-of-experts model..." I did not finish that sentence. Parameter counts inside a truncated description are catalog text, not a measurement.
Reasoning is not mandatory. default_enabled is true. default_effort is high. 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. I report what I sent, which is nothing in that field.
top_provider.max_completion_tokens is 393,216. I sent max_tokens 65536, the unnamed script default. I did not raise it. The models list had no deepseek/deepseek-v4.1-flash-1017:batch id. A :batch id exists for deepseek/deepseek-v4.1-flash, not for this snapshot. Batch was not used.
List price at generate time, Saturday row: prompt 0.00000015, completion 0.0000006, per token. Catalog default_parameters is an empty object. The stream script sent temperature 0.7. I did not send top_p. I did not send a system message.

meta.json has elapsed_s 866.0072595890379. The table rounds that to 866.01 s. Cost is the usage object's cost field, 0.01117438. Upstream inference prompt cost is 0.00000616. Completions cost is 0.01116822.
List price times the token counts is $0.0159612. The usage object says $0.01117438. I am reporting the usage field, not the product.
usage.reasoning_tokens is 20,359. Streamed reasoning is 65,851 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 44 prompt tokens. I did not send a system prompt.
content.md opens with a sentence about a living canvas, then the fence, then a "Design Highlights" section after the closing fence. The shipped file is the first fence only. Prose before and after is leftover chatter. I did not publish it as the page.
How it handled the brief
The brief is empty. This run built one page: two full-window 2D canvases, a type hero, a breathing halo, a grain overlay, a vignette, and one inline script. node --check exit 0. 595 lines. The last line is </html> and there is a trailing newline.
Fonts are a live dependency. The page links Google Fonts for Cormorant Garamond and Inter. I did not record those status codes. The still shows an italic display serif. No picsum. No <script src>.
http://www.w3.org/2000/svg appears inside a data-URI grain tile. That is a namespace string, not a fetch.
finish_reason was stop. The file closes </html>. I did not retry.
The HTML
This is the fence, unchanged. sha256 e3c4441a9e0cf0cc14a6ed81091202a2b4f4c94e07c4ceeeb8178aba8337dec9.

Series, this row only
Older rows stay on the 16 Oct post and the 10 Sep LUMEN post. I am not restating them. This row is this morning's run.
| Model | Where | Wall | Tokens | HTML | Cost | Piece |
|---|---|---|---|---|---|---|
| DeepSeek V4.1 Flash 1017 | OpenRouter sync | 866.01 s | 26,635 | 20,747 B | $0.01117438 | Aether |
The 10 Sep Official A write-up is a different product, on the unpinned slug: V4.1 Flash, 117 of 157. This page is not that score.
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: e3c4441a9e0cf0cc14a6ed81091202a2b4f4c94e07c4ceeeb8178aba8337dec9.
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 Official A. The 117 of 157 is the 10 Sep post on
deepseek/deepseek-v4.1-flash. I did not rescore this snapshot. - 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. I do not claim the particles respond.
- I did not send a reasoning effort. Catalog
default_effortishighanddefault_enabledis true. Those fields are not this payload. max_tokenswas 65536. The provider cap is 393,216. This call finishedstop, so the lower cap did not cut the page.
Reproducing
Workspace: ~/workspace/deepseek-v4.1-flash-1017-tests/01-most-beautiful-html/ (prompt.txt, content.md, reasoning.md, meta.json, page.html, runtime-gate.json).
OUT_DIR=... MODEL=deepseek/deepseek-v4.1-flash-1017 python3 stream_openrouter_oneshot.py
REASONING_EFFORT was unset. TEMPERATURE was unset, so the script sent 0.7. top_p was not sent. The stream wrote reasoning.md.
Verification notes
