Three families dominate open-source AI in 2026: DeepSeek from China's DeepSeek AI, Llama from Meta, and Qwen from Alibaba. Each has multiple model sizes, different architectures, and distinct strengths.

The question everyone running local models asks: which one should I actually download?

The answer depends on what you're doing, what GPU you have, and whether you care more about raw intelligence or inference speed. This guide compares all three across real benchmarks, VRAM requirements, and practical use cases.

Quick Verdict

DeepSeek Llama Qwen
Best model R1 (reasoning), V3.2 (general) 3.3 70B (balanced), 4 Maverick (latest) 3.5 (flagship), 3-30B-A3B (efficient)
Top strength Reasoning & math Ecosystem & tooling Coding & multilingual
VRAM (best local) 8GB (R1 distill 14B) 38GB (3.3 70B) 16GB (3-30B-A3B MoE)
License MIT Llama License (restricted) Apache 2.0 (most open)
Best for Complex reasoning, research General purpose, chat Coding, agents, multilingual

TL;DR: Qwen leads benchmarks and has the most permissive license. DeepSeek R1 dominates reasoning tasks. Llama has the biggest ecosystem but is falling behind on performance-per-parameter. For most local users in 2026, Qwen 3 is the default choice.

The Families at a Glance

DeepSeek: The Reasoning Specialist

DeepSeek made headlines in January 2025 with R1, a reasoning model that matched OpenAI's o1 on math benchmarks — at a fraction of the training cost. Their approach: Mixture of Experts (MoE) architecture that activates only a fraction of the model's parameters per token.

Current lineup:

  • DeepSeek R1 (671B total, ~37B active): Chain-of-thought reasoning model. MMLU-Pro 84.0, AIME 97.3. The gold standard for math and logical reasoning.
  • DeepSeek V3.2 (685B total): General-purpose successor. Chatbot Arena 1423. Strong all-rounder.
  • R1 Distills (7B/14B/32B/70B): Smaller models trained to mimic R1's reasoning. The 14B and 32B distills are the practical local models.

The catch: Full R1 and V3 require 351GB VRAM (FP16) — that's 4-5 enterprise GPUs. For local use, you're running distills or heavily quantized versions.

Llama: The Ecosystem King

Meta's Llama family has the largest community, the most fine-tunes, and the broadest tool support. Every inference framework (Ollama, vLLM, llama.cpp) supports Llama first.

Current lineup:

  • Llama 4 Maverick (400B MoE): Latest flagship. MMLU-Pro 80.5, 1M context window. Impressive specs, but Chatbot Arena at 1328 suggests real-world performance lags behind benchmarks.
  • Llama 4 Scout (109B MoE): Efficient variant with 10M context. Early stage — limited benchmark data.
  • Llama 3.3 70B: The workhorse. MMLU-Pro 68.9, IFEval 92.1. Mature, well-tested, runs on a single RTX 4090 with Q4 quantization.

The catch: Llama License is more restrictive than MIT or Apache — commercial use requires compliance with Meta's terms. And Llama 4's early benchmarks are disappointing relative to the parameter count.

Qwen: The Benchmark Leader

Alibaba's Qwen team has been on an absolute tear. Qwen 3.5 tops virtually every open-source benchmark in March 2026, and their MoE models offer exceptional performance per VRAM dollar.

Current lineup:

  • Qwen 3.5 (397B): Flagship. MMLU-Pro 87.8, GPQA Diamond 88.4, Chatbot Arena 1450. The best open-source model by most measures.
  • Qwen 3-30B-A3B (30B total, 3B active): MoE efficiency monster. Chatbot Arena 1384 — near Llama 3.3 70B performance at a fraction of the VRAM.
  • Qwen3-Coder-Next (80B): Specialized coding model. SWE-bench 70.6, HumanEval 94.1.
  • Qwen 3.5-9B and Qwen 3.5-4B: Small models for edge deployment.

The catch: Less community tooling than Llama. Some users report slower Ollama integration for new Qwen releases compared to Llama models.

Head-to-Head Benchmarks

Real numbers from published benchmarks (sources: Onyx self-hosted leaderboard, LMArena, official model papers):

Knowledge & Reasoning

Benchmark DeepSeek R1 Llama 3.3 70B Llama 4 Maverick Qwen 3.5 Qwen 3-30B-A3B
MMLU-Pro 84.0 68.9 80.5 87.8 68.7
GPQA Diamond 71.5 50.7 69.8 88.4 60.0
IFEval 83.3 92.1 N/A 92.6 N/A
Chatbot Arena 1398 1319 1328 1450 1384

Qwen 3.5 dominates knowledge and reasoning benchmarks. DeepSeek R1 is strong but falls behind on GPQA Diamond (graduate-level science). Llama 3.3 70B holds its own on instruction following (IFEval) but trails on raw knowledge.

Coding

Benchmark DeepSeek R1 Llama 3.3 70B Qwen 3.5 Qwen3-Coder-Next
HumanEval 90.2 88.4 N/A 94.1
SWE-bench Verified 49.2 N/A 76.4 70.6
LiveCodeBench 65.9 N/A 83.6 74.5

Qwen leads coding benchmarks decisively. The gap on SWE-bench (real-world bug fixing) is dramatic — 76.4 vs 49.2 for DeepSeek R1.

Math

Benchmark DeepSeek R1 Llama 3.3 70B Qwen 3.5 Qwen 3-30B-A3B
AIME 2025 97.3 77.0 N/A 95.2
MATH-500 87.5 N/A N/A 76.7

DeepSeek R1 still leads math. This is its designed purpose — chain-of-thought reasoning for mathematical and logical problems. The Qwen 3-30B-A3B MoE model is surprisingly competitive at 95.2 on AIME while using a fraction of the compute.

VRAM Requirements & Local Inference

This is where the rubber meets the road for local users:

Models You Can Actually Run Locally

Model Parameters Min VRAM (Q4) Recommended VRAM Speed (RTX 4090)*
Qwen 3.5-4B 4B 3GB 4GB ~80 tok/s
DS-R1-Distill-Qwen-7B 7B 4GB 6GB ~55 tok/s
Qwen 3.5-9B 9B 5GB 8GB ~45 tok/s
Llama 3.1 8B 8B 5GB 8GB ~50 tok/s
DS-R1-Distill-Qwen-14B 14B 8GB 12GB ~35 tok/s
Phi-4 14B 9GB 12GB ~30 tok/s
Qwen 3-30B-A3B 30B (3B active) 16GB 16GB ~40 tok/s
Gemma 3 27B 27B 14GB 24GB ~25 tok/s
Llama 3.3 70B 70B 38GB 48GB ~15 tok/s
DS-R1-Distill-Qwen-32B 32B 17GB 24GB ~20 tok/s

*Approximate generation speed, Q4_K_M quantization via Ollama.

The Efficiency Sweet Spot

Qwen 3-30B-A3B deserves special attention. It's a 30B parameter MoE model that activates only 3B parameters per token. Result: Chatbot Arena 1384 (near Llama 3.3 70B level) while fitting in 16GB VRAM and generating tokens at ~40 tok/s.

For most local users with a single consumer GPU, this is the best model you can run in 2026. It's not a compromise — it genuinely competes with models 2-3× its active parameter count.

GPU Recommendations by Model Tier

Architecture Differences That Matter

DeepSeek: MoE + Chain-of-Thought

DeepSeek pioneered affordable MoE training. R1 uses chain-of-thought reasoning — it "thinks" step-by-step before answering. This makes it excellent for math and logic but slower for simple queries (it thinks even when thinking isn't needed). The distilled versions lose some reasoning depth but gain speed.

Llama: Dense Transformers

Llama 3.3 is a traditional dense model — every parameter activates for every token. This makes it predictable and well-optimized across all inference frameworks. Llama 4 shifted to MoE (Maverick has 400B total, ~17B active), but early performance hasn't matched expectations.

Qwen: MoE + Specialized Variants

Qwen 3 offers both dense models (3.5-4B, 3.5-9B) and MoE models (3-30B-A3B, 3-235B-A22B). Their MoE implementation is particularly efficient — the 30B-A3B variant activates only 10% of parameters while maintaining competitive benchmark scores. Qwen also ships specialized models (Coder, Math) that outperform general-purpose models on specific tasks.

License Comparison

Family License Commercial Use Restrictions
DeepSeek MIT ✅ Unrestricted None
Llama Llama License ⚠️ Conditional Monthly active users > 700M must request permission
Qwen Apache 2.0 ✅ Unrestricted None

For commercial applications, Qwen (Apache 2.0) and DeepSeek (MIT) are the safest choices. Llama's license is fine for most companies but introduces a dependency on Meta's terms.

When to Pick Each

Pick DeepSeek When:

  • Math, logic, or scientific reasoning is your primary use case
  • You want chain-of-thought reasoning with transparent "thinking"
  • You're using the distilled models (14B, 32B) for efficient local reasoning
  • MIT license matters for your project

Pick Llama When:

  • Ecosystem compatibility is critical (most fine-tunes, widest tool support)
  • You need a battle-tested 70B model with extensive community validation
  • You're already invested in Meta's AI ecosystem
  • Long context windows matter (Llama 4 Scout offers 10M context)

Pick Qwen When:

  • Raw benchmark performance matters (Qwen 3.5 leads almost everything)
  • Coding is a primary use case (Qwen Coder models are exceptional)
  • You need maximum performance per VRAM (Qwen 3-30B-A3B is unmatched)
  • Apache 2.0 licensing is required
  • Multilingual support (especially CJK languages) is important

The Bottom Line

In March 2026, Qwen leads the open-source LLM race on benchmarks, licensing, and efficiency. DeepSeek R1 remains the best choice for pure reasoning tasks, and Llama 3.3 70B is the safe, well-tested generalist.

For local inference on consumer hardware:

  • Best overall: Qwen 3-30B-A3B (16GB VRAM, Chatbot Arena 1384)
  • Best reasoning: DS-R1-Distill-Qwen-32B (24GB VRAM)
  • Best ecosystem: Llama 3.3 70B (48GB VRAM)
  • Best budget: DS-R1-Distill-Qwen-14B or Qwen 3.5-9B (8GB VRAM)

All three families are available through Ollama with a single ollama pull command. Try the Qwen 3-30B-A3B first — it's the model that made us rethink what's possible on a single GPU.
