DeepSeek
TOP FEATURES · 12
F01
DeepSeek-V4 ModelsaiDeepSeek's V4 model family includes two API tiers — V4-Flash for fast general-purpose inference and V4-Pro for maximum reasoning performance. Both run on a Mixture-of-Experts architecture with a 1M token context window and 384K max output. Models are accessible via the free web chat at chat.deepseek.com, iOS/Android apps, and the REST API. Context caching reduces repeated prefix costs by 90%.
F02
Thinking Mode (Chain-of-Thought Reasoning)aiBefore outputting a final answer, DeepSeek's thinking mode produces a chain-of-thought reasoning trace (reasoning_content) to improve accuracy on complex tasks. Thinking mode is the default on V4-Pro and available on V4-Flash. Outputs run up to 384K tokens for extended reasoning chains.
F03
Tool Calls (Function Calling)automationDeepSeek's API allows the model to call external functions and tools to enhance its capabilities. Supported in both thinking and non-thinking modes, with a strict mode (Beta) that enforces exact JSON schema compliance on tool outputs.
F04
JSON Output (Structured Output)dataDeepSeek provides a JSON Output mode that guarantees the model returns valid, parseable JSON strings. Users set the response_format parameter to json_object and include a JSON example in their prompt to guide structured output for downstream parsing.
F05
Context Caching (KV Cache on Disk)storageThe DeepSeek API automatically caches request prefixes on disk for all users at no extra configuration. Repeated prefix tokens in subsequent requests trigger a cache hit, reducing cost from $0.28 to $0.0028 per 1M input tokens — a 90% discount.
F06
FIM Completion — Fill in the Middle (Beta)editingUsers can supply a code or text prefix and optional suffix, and the model fills in the middle content. Commonly used for code completion and content completion tasks, integrating natively with VS Code via the Continue plugin. Non-thinking mode only (V4 restriction). In V3.2, FIM was available in both modes; V4 restricts it to non-thinking mode.

AI Music Generation (Lyria 3)audioCreates custom soundtracks from text descriptions or photos using the Lyria 3 music generation model. Higher limits on Pro and Ultra.
WHO IT'S FOR
Who each tool is built for
Use cases and fit tags from each tool's own positioning. Match these to your context, not their marketing.
developerTeams use V4-Pro's thinking mode to construct autonomous agents that reason before acting. The model outputs chain-of-thought internally, then calls external tools (database queries, API hits, calculations) based on that reasoning. Thinking blocks remain cached across turns, reducing token cost by 90% when the same reasoning pattern repeats. Ideal for code review workflows, data validation pipelines, and itinerary planning agents.
developerExisting OpenAI SDK codebases switch to DeepSeek by changing one line (the base_url), keeping all tool-calling logic and streaming intact. V4-Flash delivers GPT-4 level output performance at Flash pricing ($0.28/M tokens output). Supports Anthropic SDK format too, so teams running both OpenAI and Anthropic models can route to DeepSeek without refactoring.
developerDevelopers send 500K+ token documents (entire codebases, research papers, contract batches) to V4's 1M context window for semantic search, cross-file refactoring suggestions, or bulk summarization. Context caching keeps repeated sections cheap ($0.0028/M cached tokens). Previously hitting 128K limits mid-document is now a non-issue.
researchAnalysts use Deep Research to scan and synthesize hundreds of live sources in minutes, then get structured reports — not summaries of a training snapshot. Live data access is critical for time-sensitive research on breaking developments.
