DeepSeek-V3.2: corrected release date to 1 December 2025

The OnAirToday AI Progress Tracker recorded a verified change to DeepSeek's DeepSeek-V3.2 (version V3.2): Corrected release date to 1 December 2025.

DeepSeek-V3.2 is an open-weight, text-only mixture-of-experts model supporting reasoning, tool use and a documented 128K context window. This profile reflects December 2025 release documentation; current availability, pricing and successor releases could not be checked live.

What changed in this review:

• Replaced zero prices with release-documented USD per million tokens: $0.28 uncached input and $0.42 output; current rates unverified.
• Added published GPQA Diamond, LiveCodeBench v6, Humanity's Last Exam and Terminal-Bench 2.0 results.
• Specified AIME 2025 rather than an unspecified AIME edition.
• Removed the unsupported predecessor-relative price-reduction claim; sparse attention was already introduced in V3.2-Exp.
• Capability score 83.1 → 69
• Flaws and limitations updated

Teams building on DeepSeek-V3.2 should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.

The full profile — capabilities, benchmark citations, known flaws and risk guidance — is on the tracker at /ai-models/deepseek-v3-2.
