> DeepSeek’s API changelog launched experimental DeepSeek-V4-Flash-Vision-Exp: JPEG/PNG/GIF/WebP via base64, URL, or Files API file_id, on Chat Completions, Anthropic-compatible Messages, and Responses. Text-agent scores match official V4-Flash; DeepSeek says multimodal-agent results jump toward Claude Opus 4.8. Lab-claimed — independent Arena / Artificial Analysis listings were not confirmed. Distinct from the August 13 V4-Pro GA and price hike.

DeepSeek’s V4 family has been **text-agent** priced. A Flash-class **vision** endpoint, on the same three API dialects, is how Hangzhou keeps OpenClaw/Codex-style harnesses from routing screenshots to Gemini or GPT-5.6.

**DeepSeek** added **DeepSeek-V4-Flash-Vision-Exp** to the API (`model='deepseek-v4-flash-vision-exp'`). Images: **JPEG / PNG / GIF / WebP** via **base64**, public **URL**, or Files API **`file_id`**. Surfaces: Chat Completions, **Anthropic-compatible Messages**, and **Responses**. DeepSeek: **pure-text** agent/reasoning matches official **V4-Flash**; on **vision-required agent** benches the experimental model “delivers a significant leap,” “close to **Opus-4.8**.” Independent Arena / Artificial Analysis listings were **not confirmed** in the research window — treat as **lab-claimed**, too new for third-party boards.

## Lab benches (changelog)

| Bench | V4-Flash-Vision-Exp |
|-------|---------------------|
| Terminal Bench 2.1 | **83.9** |
| NL2Repo | **57.7** |
| DeepSWE | **59.3** |
| DSBench-Hard | **63.6** |
| AutomationBench (Public) | **25.7** |
| ApexBench (Pass@1) | **36.5** |
| Agents' Last Exam | **27.3** |
| Chartography | **64.3** |
| ZeroBench (Pass@5) | **35.0** |

Text-agent numbers used DeepSeek Harness **minimal mode**, **max** effort, topp **0.95**, temp **1.0**. ApexBench and Agents' Last Exam: the **text** V4-Flash **ignores multimodal elements** — so those two are not a vision-vs-text comparison.

**Independent rankings**: not listed on Artificial Analysis / LMArena in this window. Do not invent an Intelligence Index.

Not V4-Pro GA or the **Aug 13** price/peak-off-peak announcement (effective Aug 16). This is a **new multimodal experimental SKU**.

## Limits

- Vision “close to Opus-4.8” is **lab-claimed**; no AA/Arena listing confirmed.
- Whether Vision-Exp graduates without a price multiplier is open.
- Chartography **64.3** has not been independently re-run on images.
