DeepSeek opens the full App experience via API: built-in search, files and URL reading on V4.1-Flash, plus standalone OCR, ASR and TTS with separate tool fees

Why it matters

【Key points】

· Release: On 13 Nov 2026, DeepSeek’s API changelog opened the App/web stack to developers; @deepseek_ai posted it at 14:24 UTC. Not a new model; it targets existing deepseek-flash (V4.1-Flash-1017).

· In-chat tools: On Messages, Responses and Chat Completions, the service can run web or image search with citations, multi-step search and link reading, parsed file uploads, URL fetching, and an optional safety check that returns a refusal marker on risk.

· Standalone APIs: Search, Fetch, OCR, ASR and TTS can also be called alone. An official open-source demo can import chat history.

• · Pricing: Tool use is billed on top of tokens.
• Search and web fetch are $0.75 per 1,000, same as the 17 Oct list price, now also when used as tools.
• File parsing / OCR is $0.225 per 1,000 pages.
• TTS is $0.45 per 10,000 characters ($0.225 at limited-time 50% off); ASR is $0.116 per audio hour ($0.058 at 50% off).
• No discount end date is given.

【Our read】

Background

• These capabilities already formed the consumer DeepSeek experience.
• On 17 Oct the lab opened only its in-house search engine as Search and Fetch APIs.
• This drops that product stack into the existing API.

Comparison

This is closer to the built-in web, file and voice tools already offered by OpenAI and Anthropic, without a new model. Search and fetch prices are unchanged; new costs are file/OCR, speech, and how often tools fire.

Impact

• Teams can drop a layer of external search, OCR and speech.
• Tool fees stack on already-low Flash token prices, and deep-thinking search can multiply the bill.
• For public-facing apps, the safety parameter and China registration/labeling duties are part of the design.
• This is not a model leap.
