Meta's Llama 4 followed in late 2025. The two are now the dominant open-weights families in 2026. Here is the head-to-head that actually matters.\n\n## What changed in 2026\n\n- **Both went MoE.** Qwen 3 235B-A22B and Llama 4 Maverick 400B-A17B both use mixture-of-experts. Quality scaled, inference cost stayed reasonable.\n- **Multilingual got serious.** Qwen 3 trained heavily on CJK plus 100+ languages. Llama 4 expanded to 50+. The gap is meaningful for non-English deployments.\n- **Licensing diverges.** Qwen 3 is Apache 2.0 (truly permissive). Llama 4 is community license (>700M MAU restriction).\n\n## Multilingual benchmarks\n\n| Language | Qwen 3 (235B-A22B) | Llama 4 Maverick |\n| --- | --- | --- |\n| English (MMLU) | 87.0 | 89.0 |\n| Chinese (CMMLU) | 85.5 | 73.5 |\n| Japanese (JMMLU) | 78.0 | 68.0 |\n| Korean (KMMLU) | 73.5 | 64.0 |\n| French (MMLU-FR) | 79.5 | 81.0 |\n| German (MMLU-DE) | 78.0 | 80.5 |\n| Arabic (MMLU-AR) | 71.0 | 69.5 |\n\nFor CJK markets, Qwen is decisive. For European languages, they're roughly even. For English-only, Llama 4 Maverick has the edge.\n\n## Coding and math\n\nLlama 4 Maverick wins on English coding (HumanEval 86.5, SWE-bench Verified 41%) over Qwen 3 (HumanEval 82.0, SWE-bench Verified 36%). On math (AIME 2024), they're within 2 points. For agentic coding pipelines in English, Llama 4 is the safer pick.\n\n## Architecture differences\n\n| Aspect | Qwen 3 235B | Llama 4 Maverick |\n| --- | --- | --- |\n| Active params | 22B | 17B |\n| Total params | 235B | 400B |\n| Experts | 128 (8 active) | 16 (2 active) |\n| Context | 128K (1M with rope scaling) | 1M (4M with extra training) |\n| License | Apache 2.0 | Llama Community |\n\nQwen's many-fine-grained-expert design tends to specialize better; Llama 4's fewer-larger-expert design has cleaner inference economics at scale.\n\n## Fine-tuning ecosystem\n\nHugging Face has 18K+ Llama 4 fine-tunes vs 6K+ Qwen 3 fine-tunes (as of April 2026). Llama 4 leads in tooling maturity (Axolotl, TRL, Unsloth all first-class). Qwen 3 has Alibaba's own DashScope tuning, which is excellent if you're deploying on Aliyun, plus growing Hugging Face support.\n\n## Deployment cost\n\nBoth are competitive on Together / Fireworks at $0.50-0.90/M input. Self-hosted on 8xH100, Qwen 3 has slightly better throughput per active param due to its expert routing. For 5M+ tokens/day, self-hosting either is below $1/M tokens; below 5M, hosted is more economical.\n\n## When to pick which\n\n**Pick Qwen 3 when:** you serve users in CJK languages, you want a truly permissive Apache 2.0 license, you operate in or sell into Asia where Aliyun integration matters, or you need an Apache-2.0 model for a downstream redistribution play.\n\n**Pick Llama 4 when:** your workload is English-dominant, you need the strongest open-weights coding model, you're using AWS Bedrock heavily (Llama is more deeply integrated), or you need >1M context.\n\n## FAQ\n\n**Can I deploy Qwen 3 in the West?**\nYes. Together, Fireworks, Hugging Face inference, and Replicate all host Qwen 3. For data sovereignty, self-hosting on AWS/GCP/Azure works fine — the weights are open.\n\n**What about Qwen 3 Coder vs Codestral?**\nQwen 3 Coder is excellent on Python and JavaScript, competitive with Codestral 3. For multilingual codebases, Qwen 3 Coder leads.\n\n**Does Qwen 3 support thinking mode?**\nYes — `<think>` tag mechanism similar to DeepSeek R1/R2 and o1. Quality on math and reasoning improves substantially with thinking enabled.\n\n## Where to go next\n\nFor related comparisons see [Llama 4 vs Llama 3 in 2026](/blog/llama-4-vs-llama-3-2026), [DeepSeek R2 review](/blog/deepseek-r2-review-2026), and [Local LLM setup guide for 2026](/blog/local-llm-setup-guide-2026).","hue":215,"metaTitle":"Qwen 3 vs Llama 4 (2026): open-weights showdown","metaDescription":"Qwen 3 vs Llama 4 in 2026 — multilingual benchmarks, MoE architecture, fine-tuning, deployment, and how to choose for your real workload.","keywords":["qwen 3 vs llama 4","qwen 3 review 2026","alibaba qwen 3","qwen 3 multilingual","llama 4 maverick","chinese ai models 2026","open weights comparison","qwen 3 235b","moe llm 2026","asian language ai"],"tldr":["**Qwen 3 leads decisively on Chinese, Japanese, and Korean.** 8-12 point gap on CMMLU, JMMLU, KMMLU vs Llama 4.","**Llama 4 Maverick wins English coding and math by 3-4 points.** SWE-bench Verified shows the gap clearly.","**Both are MoE.** Qwen 3 235B-A22B vs Llama 4 Maverick 400B-A17B — different active-param tradeoffs.","**Skip:** picking on benchmarks alone — license, ecosystem, and regional latency matter."],"readTime":"3 min read","wordCount":624},"related":[{"slug":"best-open-source-llms-2026","title":"Best open-source LLMs in 2026: Llama, Mistral, Qwen, DeepSeek compared","excerpt":"Open-source models finally caught up to the frontier on most non-reasoning tasks.
