DeepSeek
DeepSeek is now tracked from the official English API docs. The current API model line lists deepseek-v4-flash and deepseek-v4-pro with 1M context, 384K maximum output, thinking/non-thinking modes, JSON output, tool calls, context caching, OpenAI API compatibility and Anthropic API compatibility. The legacy names deepseek-chat and deepseek-reasoner are documented as compatibility aliases for V4-Flash and are scheduled for deprecation on 2026-07-24.
Editorial verdict
Developers evaluating Chinese model APIs for coding agents, reasoning, tool use and OpenAI/Anthropic-compatible migration.
Avoid new integrations that still hard-code deepseek-chat or deepseek-reasoner without a migration plan to V4 model names.
The English docs now make DeepSeek's current API shape explicit: V4-Pro/V4-Flash, dual OpenAI/Anthropic compatibility, thinking mode, tool calls, caching and agent-tool integrations.
Usage-based API pricing per 1M tokens; V4-Pro discount is documented through 2026-05-31 15:59 UTC
Topped-up balance, Granted balance, Platform billing
API commercial use should follow the active platform terms.
Treat prompts and logs as vendor-processed data unless enterprise terms say otherwise.
Use deepseek-v4-pro or deepseek-v4-flash directly, rather than relying on deprecated compatibility aliases.
Official docs list integrations for Claude Code, GitHub Copilot, OpenCode, Kilo Code, OpenClaw and other agent tools.
V4 models document 1M context, 384K max output and context caching with cache-hit usage fields.
Recheck the docs before deployment: DeepSeek-V4 was added on 2026-04-24, legacy aliases are scheduled for 2026-07-24 deprecation, and model pricing can change.
Qwen is one option when deployment and cloud billing matter.
