Where each one wins

Nemotron 3 Nano Omni — multimodal agents

The key differentiator: audio is a first-class modality in the same model that sees images and reads text.

For agent workloads that mix media — customer service that watches a screen recording while listening to the call, monitoring agents that correlate dashboards with voice alerts, research agents that read papers and watch lecture videos — running one model is materially better than orchestrating Whisper + a vision model + an LLM.

NVIDIA also released the most open package: weights, 15 training datasets, RL trajectories, and tool-call data. For researchers fine-tuning on multimodal tasks, this is the most workable starting point in 2026.

Limits:

• Pure text reasoning trails Llama 5 flagship and closed models.
• Smaller context window than Gemini 3.1 Pro or Claude Opus 4.7.
• Ecosystem is younger — fewer fine-tunes and integrations than Llama.

Llama 5 — the ecosystem default

The key differentiator: every tool already supports it.

Llama 5 is the safe choice. Released April 5, 2026, it has:

• Variants from 8B (edge) to 400B+ (frontier).
• Llama 5V multimodal vision sibling.
• Day-one support in vLLM, TensorRT-LLM, llama.cpp, MLX, Ollama, LM Studio.
• The largest fine-tune ecosystem (instruction-tuned, code-tuned, domain-tuned variants).
• Strong instruction following and tool use.

For most production deployments where multimodal isn’t the core requirement, Llama 5 will be easier to ship.

Limits:

• License has a 700M monthly active users threshold and other restrictions — fine for most companies, blocks the largest competitors.
• Native audio not in the core model — need a separate ASR.
• Flagship variant requires serious GPU infrastructure.

Qwen 3.6 — multilingual and Apache 2.0

The key differentiator: Apache 2.0 license and best non-English performance.

Alibaba ships aggressive licensing — Apache 2.0 means use it however you want, no thresholds. Qwen 3.6 is the strongest open model on Chinese, Japanese, Korean, and many Asian languages. It also competes well on English tasks at the 70-235B sizes.

For teams in or selling into Asia, or any team that needs the most permissive license, Qwen 3.6 is hard to beat.

Limits:

• Multimodality lives in separate Qwen-VL models (good but not unified).
• Smaller US/EU community than Llama.
• Some training-data transparency questions remain.

Hardware reality

Model	Minimum (FP8/4-bit)	Production (full precision)
Nemotron 3 Nano Omni 30B	1× RTX 5090 (4-bit)	1× H100 (FP8) or H200
Llama 5 8B	1× RTX 4090	1× A100
Llama 5 70B	2× H100 (FP8)	4× H100
Llama 5 400B+	Cluster only	8× H200 / B200 cluster
Qwen 3.6 7B	1× RTX 4090	1× A100
Qwen 3.6 72B	2× H100 (FP8)	4× H100
Qwen 3.6 235B MoE	4× H100 (FP8)	8× H100 / 4× H200

For most teams, the 30-70B range is the sweet spot — fits on 1-4 GPUs, runs fast, and quality is high. Nemotron 3 Nano Omni and Llama 5 70B and Qwen 3.6 72B are all viable here.

Benchmarks (representative, April 2026)

Reasoning and knowledge (MMLU-Pro, higher is better):

• Llama 5 flagship: ~78
• Qwen 3.6 235B MoE: ~76
• Nemotron 3 Nano Omni: ~71

Multimodal understanding (MMMU, higher is better):

• Nemotron 3 Nano Omni: ~73
• Llama 5V: ~70
• Qwen-VL 3.6: ~68

Audio + multimodal agentic tasks (NVIDIA-published):

• Nemotron 3 Nano Omni: best in class (no direct open competitor with audio in-core)

Coding (HumanEval+):

• Llama 5 Code variant: ~84
• Qwen 3.6 Coder: ~83
• Nemotron 3 Nano Omni: ~76

(Numbers from vendor reports and early third-party evals; expect movement as more independent benchmarks land.)

Which to pick

Build agents that mix audio, video, and text: Nemotron 3 Nano Omni. No other open model handles all four modalities natively in April 2026.

Build a general-purpose AI app and want maximum tooling: Llama 5. The ecosystem is years ahead.

Need permissive licensing or non-English performance: Qwen 3.6. Apache 2.0 plus strong multilingual is unmatched.

Sovereign or air-gapped deployment with NVIDIA hardware: Nemotron 3 Nano Omni. NVIDIA’s open data commitment, NIM microservices, and TensorRT-LLM tuning make it the smoothest path.

You don’t know yet: Start with Llama 5. Switch to Nemotron when audio/video matters or to Qwen when license matters.

What changes next

NVIDIA has flagged Nemotron 3 Super and Nemotron 3 Ultra for the first half of 2026 — expect these to push open multimodal reasoning further. Llama 5 will likely see point releases through the year. Qwen 3.7 is rumored. For now, this three-way race is the open-multimodal landscape, and Nemotron 3 Nano Omni’s April 28 release just shifted it.
