Collected with this tool against https://api.deepseek.com/v1, model id deepseek-flash (API name: DeepSeek-V4.1-Flash), standard preset (8 cells x 25 samples), protocol one-token/v1, reasoning disabled via the openai-effort adapter. 200/200 valid, 0 errors. Unlike the bundled Zenodo samples, this reference is protocol-matched to the package battery, so compare()/verify() against it is a direct comparison.

# Reference fingerprints (trusted, collected with this tool)
|
||
|
||
These are **first-party** references — collected by `llm-fingerprint-detector`
|
||
itself against a provider you trust, using the package's own `one-token/v1`
|
||
battery. Unlike `../reference-fingerprints.sample.json` (Zenodo paper data,
|
||
`bruckner-zenodo-2026` protocol), these are protocol-matched, so a
|
||
`compare()` against them is a direct, non-indicative comparison.
|
||
|
||
| file | model id | provider | collected | protocol | battery |
|
||
|---|---|---|---|---|---|
|
||
| `deepseek-v4.1-flash.official.json` | `deepseek-flash` | api.deepseek.com (official) | 2026-10-04 | `one-token/v1` | 8 cells × 25 samples |
|
||
|
||
## `deepseek-v4.1-flash.official.json`
|
||
|
||
- **Endpoint:** `https://api.deepseek.com/v1`
|
||
- **Model id requested:** `deepseek-flash` (API-reported name: `DeepSeek-V4.1-Flash`)
|
||
- **Collected:** 2026-10-04, standard preset, `temperature=1`, reasoning disabled
|
||
via the `openai-effort` adapter
|
||
- **Result:** 200/200 samples valid, 0 errors, `postReasoning: false`
|
||
- **Use it to verify a reseller:** a reseller advertising `deepseek-v4.1-flash`
|
||
(or `deepseek-flash`) should land in the *match* band against this file.
|
||
|
||
```bash
|
||
# verify a suspect endpoint against this trusted reference
|
||
llm-fingerprint verify \
|
||
--base-url https://reseller.example.com/v1 \
|
||
--model deepseek-v4.1-flash \
|
||
--reference data/references/deepseek-v4.1-flash.official.json
|
||
```
|
||
|
||
### The official fingerprint's most discriminative cells
|
||
|
||
| cell | official DeepSeek-V4.1-Flash | notes |
|
||
|---|---|---|
|
||
| `random-number-1-100:en` | `42` ×19 / 25 | overwhelming 42 bias |
|
||
| `random-number-1-100:zh` | `42` ×14 / 25 | same bias, Chinese |
|
||
| `random-color:en` | `blue` ×25 / 25 | fully deterministic |
|
||
| `coin-flip:en` | `heads` ×25 / 25 | fully deterministic |
|
||
| `random-number-1-10:en` | `7` ×23 / 25 | near-deterministic |
|
||
| `random-letter:en` | `q` ×18 / 25 | q ≫ k ≫ g |
|
||
| `random-color:zh` | `蓝` ×20 / 25 | 蓝 ≫ 紫, 橙 |
|
||
| `random-animal:en` | `elephant` ×11, `cat` ×9 | elephant dominates |
|
||
|
||
**Caveat:** references drift as providers ship model updates. Re-collect if the
|
||
file is more than ~1–2 months old, or if a verification you trust starts
|
||
returning `uncertain`.
