According to CoinMeta, DeepSeek has officially launched the "all-in-one" application API, providing third-party developers with networking search, advanced thinking search, file parsing, web browsing, and voice capabilities that were previously integrated within the official App. Developers now only need to enable the corresponding parameters in the existing API, and DeepSeek will automatically handle tool calls and context stitching on the server side. The model can search web pages and read links while thinking, and it can also answer questions by combining uploaded PDF and Office documents and images. In addition, DeepSeek has also made available independent interfaces for search, web scraping, OCR (image text recognition), ASR (voice to text), and TTS (text to voice). Developers can use the entire set of dialogue functions or just call one of them. The official team has also open-sourced a chat application demo that supports multi-round conversations, voice input, read-aloud responses, and the import of DeepSeek historical chat records. Developers can directly modify it to build their own DeepSeek chat products.
