DEEPSEEK V4 PRO · RELEASE RADAROFFICIAL STATUS · JUL 31, 2026
Use DeepSeek V4 Pro in Tabbit
A practical path from a one-million-token reasoning model to real browser work—pages, files, research, and Agent tasks in one workspace.
Formal V4 Pro release is coming ASAP
DeepSeek says today’s upgrade applies to V4 Flash only. V4 Pro API and App/Web models are unchanged for now. Tabbit availability is not yet announced.
Free for macOS and Windows. Select V4 Pro after it appears in Tabbit’s model picker.
WHY IT MATTERS
A model built for work that does not fit in one prompt
V4 Pro’s technical profile matters most when the task spans long context, many sources, and multiple steps—not for another isolated chat box.
49B
Active parameters
A large MoE design aims at difficult knowledge, reasoning, coding, and long-horizon Agent work.
3×
Reasoning modes
Non-think, Think High, and Think Max let the model trade response speed for deeper analysis.
MODEL × BROWSER
Tabbit supplies the context and the hands
The model reasons. Tabbit connects that reasoning to the web workspace where the task actually lives.
01
@ reference pages and files
Attach an open tab, a tab group, a screenshot, a bookmark, or a local file without copy-and-paste.
02
Agent Mode executes the plan
Research across sites, extract facts, fill forms, and organize results in a separate task group.
03
Switch models by task
Keep one browser workflow and choose the available model that best fits speed, depth, or language.
04
You keep approval control
Review important actions and outputs before treating an AI result as final.

WORKFLOW PREVIEW
From a search to a finished research task
