Type “deepseek 3.2” into Google and you instantly see what people care about:

“deepseek 3.2 exp”, “deepseek 3.2 speciale”, “deepseek 3.2 benchmark”, “pricing”, “vs GPT-5”, “reddit”…

That’s because DeepSeek 3.2 isn’t just another model drop. It’s the moment open-source AI seriously crashes the GPT-5 / Gemini 3.0 Pro party.

In this post, we’ll break down:

  • What Deepseek 3.2 actually is
  • The differences between the three model variants
  • The key benchmarks (including those gold-medal math scores)
  • Why its sparse attention and RL training approach are a big deal
  • How you can start using or hosting it yourself

What is Deepseek 3.2?

Deepseek 3.2 is the latest flagship family of large language models from Chinese AI lab DeepSeek.

It’s built on their V3 MoE (mixture-of-experts) architecture, scaled up to:

  • 685B total parameters, with 671B in the main model and 37B “active” parameters used per token at inference
  • 128K context length, optimized for long-context reasoning and agent workflows

Unlike many frontier models, Deepseek 3.2 is open-weight and MIT-licensed.

This means you can download the weights, modify them, and use them commercially with very light restrictions. Read more about Deepseek 3.2’s official launch and details here.

And performance-wise?

DeepSeek explicitly positions V3.2 as “your daily driver at GPT-5-level performance,” with the high-compute variant V3.2-Speciale rivalling Gemini 3.0 Pro on reasoning tasks.

The Deepseek 3.2 Family: Which Model Should You Use?

Let’s untangle the three names you’ll see everywhere: deepseek 3.2, deepseek 3.2 exp, and deepseek 3.2 speciale.

Comparison Table: Base vs Exp vs Speciale

1. Deepseek 3.2 (The Balanced “Daily Driver”)

This is the “main” model most people will use.

Goal: Balance cost, speed and quality

Strengths:

  • General chat and instruction following
  • Coding assistance and debugging
  • Multi-turn reasoning
  • Long-context work
  • Agent and tool use

Positioning: DeepSeek describes it as GPT-5-class performance, but with better efficiency and full open access.

For most applications—chatbots, developer copilots, research assistants—this is the version you’d likely standardize on.

2. Deepseek 3.2 Exp (The Experimental Efficiency Monster)

Deepseek 3.2 Exp is an experimental branch built specifically to prove out a new attention mechanism called DeepSeek Sparse Attention (DSA).

Key innovation:

Instead of every token looking at every other token (which gets expensive fast), DSA lets each token selectively focus on:

  • A local window of nearby tokens
  • A small set of global “important” tokens
  • Some long-range links for structure

Real-world impact:

Long-context inference can be 50–70% cheaper while maintaining almost identical quality to V3.1-Terminus, the previous flagship.

When to use Exp:

If you care about throughput, tokens per dollar, or building huge-context applications, this is the variant to watch.

Where to find it:

  • On Hugging Face as deepseek-ai/DeepSeek-V3.2-Exp and related base models
  • On providers like Together and OpenRouter, which let you hit it via API without running 600+ GB of weights yourself

3. Deepseek 3.2 Speciale (The Max-Compute Reasoning Beast)

Then there’s deepseek 3.2 speciale—the one everyone screenshots.

This variant dials everything up for pure reasoning power.

High-compute “thinking” mode:

It uses many more tokens to reason step-by-step before answering, similar to OpenAI’s o1 model approach.

Benchmark results:

  • Gold-level performance at IMO 2025 (35/42 score) and IOI 2025 (492/600)
  • Competitive with GPT-5-High on complex coding challenges
  • Exceptional at mathematical proofs and competitive programming

The catch:

Speciale burns more tokens per answer and is currently API-only with no tool use (for clean benchmarking).

When to use Speciale:

If you’re doing research-grade reasoning, theorem proving, or hardcore competitive coding, this is the model you throw at the problem.

Deepseek 3.2 Benchmarks: Does It Really Rival GPT-5?

The short version: Yes, on many reasoning-heavy benchmarks it’s in the same league as GPT-5 and Gemini 3.0 Pro—sometimes ahead.

Math Competitions

Gold-medal level at IMO 2025 and IOI 2025:

  • IMO 2025: 35/42 score (Speciale variant)
  • IOI 2025: 492/600 score (Speciale variant)

These are the actual international Olympiad competitions, not simulated benchmarks. DeepSeek 3.2 Speciale achieved scores that would have earned gold medals.

Coding & Agent Tasks

Competitive with GPT-5-High on:

  • SWE-Verified (real software bug fixing)
  • Terminal-Bench 2.0 for complex coding workflows

Strong performance on:

  • BrowseComp (web browsing and information extraction)
  • SWE-bench style tasks (real-world software engineering)

The 3.2 line closely tracks or slightly improves on V3.1-Terminus while using fewer FLOPs per token.

Long-Context Understanding

DeepSeek 3.2 maintains strong performance across its full 128K context window, with particular strength in:

  • Multi-document synthesis
  • Long-form code analysis
  • Extended dialogue coherence

Why DeepSeek Sparse Attention (DSA) Matters

Here’s the problem DSA solves:

Most transformer models still use dense self-attention: every token attends to every other token in the sequence.

That cost scales quadratically with context length. Going from 32K to 128K context becomes exponentially more expensive.

How DSA Works (Simple Explanation)

Think of it like this:

Dense attention = Reading an entire library to answer one question

Sparse attention = Skimming the table of contents, reading relevant chapters, and checking a few key references

DSA intelligently selects only around 2,048 key-value tokens per query token instead of tens of thousands.

Real-World Benefits

  • Near-linear scaling in practice on long contexts
  • Up to ~70% cost reduction for 128K-token inference compared to dense attention
  • Almost no drop in benchmark performance versus the older V3.1 Terminus model

This is why Exp variant exists—to prove that you can maintain quality while slashing costs.

RL and Agentic Training: Why 3.2 Is So Good With Tools

DeepSeek didn’t just tweak the architecture. They also went hard on reinforcement learning and synthetic agent data.

The Training Approach

Post-training RL investment:

They dedicate over 10% of the pre-training compute budget purely to post-training RL—much more than many previous open models.

Custom agent environments:

  • Built 1,800+ distinct environments
  • Created ~85,000 complex prompts specifically for agentic tasks
  • Focus areas: browsing, tools, multi-step workflows, error recovery

What This Means for You

The result: Deepseek 3.2 is unusually good at:

  • Multi-step planning (“here’s a multi-day project, plan and execute it”)
  • Calling tools and APIs in the right order
  • Recovering from failures in longer workflows
  • Context switching between different tasks within a conversation
