DeepSeek V4 Launch: 1M Context, Flash & Pro, OpenAI-Compatible API
DeepSeek V4 arrives in Flash and Pro: 1M-token context, 384K output, tool calls, JSON mode, thinking on by default, and OpenAI/Anthropic API compatibility.
DeepSeek V4
Quietly, unhurriedly, without fuss, the Chinese released their long-awaited updated flagship in 4 versions
I’ll stoke interest: it beat the new Kimi K2.6
DeepSeek-V4-Flash and DeepSeek-V4-Pro. Both support context up to 1M tokens, maximum output up to 384K + tool calls and JSON output, meaning this isn’t just a smarter chat, but a model designed from the start for serious product and agent scenarios
The models have thinking mode enabled by default; the mode can be turned off and switched to non-thinking if speed is needed
The result is a product for production. Compatible with OpenAI- and Anthropic API formats, and the old names deepseek-chat and deepseek-reasoner are gradually being tied to deepseek-v4-flash modes
Cost — $0.14/$0.28 per 1M tokens for Flash and $1.74/$3.48 for Pro
They write that you can already try it in the web version
