NVIDIA Nemotron 3 Super vs Microsoft Phi-4

NVIDIA · US  |  Microsoft · US · Updated June 2026

Quick verdict

Pick NVIDIA Nemotron 3 Super for high-throughput agentic reasoning (up to 2.2x gpt-oss-120b) or 1m-token context with strong long-context retrieval (91.6% ruler @ 1m). Pick Microsoft Phi-4 for strong reasoning for a small 14b open-weight model or mit-licensed — fully self-hostable at no per-token cost. On a tight budget at scale, NVIDIA Nemotron 3 Super is the value pick.

NVIDIA Nemotron 3 Super (NVIDIA) and Microsoft Phi-4 (Microsoft) are two of the models people most often weigh against each other in 2026. NVIDIA Nemotron 3 Super is nVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context. Microsoft Phi-4 is microsoft's MIT-licensed 14B open model — strong reasoning for its size and very cheap, but a tiny 16K context and text-only. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

High-throughput agentic reasoning (up to 2.2x GPT-OSS-120B)

NVIDIA Nemotron 3 Super

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context — and it carries the larger 1M context.

1M-token context with strong long-context retrieval (91.6% RULER @ 1M)

NVIDIA Nemotron 3 Super

Its 1M window holds about 61× more than Microsoft Phi-4's 16K in a single prompt.

Strong math reasoning (90.21% AIME 2025)

NVIDIA Nemotron 3 Super

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context — and it is the newer of the two.

Strong reasoning for a small 14B open-weight model

Microsoft Phi-4

Microsoft Phi-4 lists strong reasoning for a small 14B open-weight model among its strengths; NVIDIA Nemotron 3 Super does not.

MIT-licensed — fully self-hostable at no per-token cost

Microsoft Phi-4

Microsoft Phi-4 lists mIT-licensed — fully self-hostable at no per-token cost among its strengths; NVIDIA Nemotron 3 Super does not.

Runs on modest or local hardware

Microsoft Phi-4

Microsoft Phi-4 lists runs on modest or local hardware among its strengths; NVIDIA Nemotron 3 Super does not.

Lowest cost at scale

NVIDIA Nemotron 3 Super

Its weights are open, so at volume you pay for your own hardware instead of Microsoft Phi-4's $0.07/$0.14 per 1M tokens.

Largest single-prompt input

NVIDIA Nemotron 3 Super

Its 1M window is about 61× larger than Microsoft Phi-4's 16K, fitting roughly 1,500 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

NVIDIA Nemotron 3 Super

At Open weight (self-host / free) it undercuts Microsoft Phi-4, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

NVIDIA Nemotron 3 Super

Larger 1M window fits more in one prompt.

Anyone whose priority is high-throughput agentic reasoning (up to 2.2x gpt-oss-120b)

NVIDIA Nemotron 3 Super

It is specifically built for that.

Anyone whose priority is strong reasoning for a small 14b open-weight model

Microsoft Phi-4

That is its strongest area.

NVIDIA Nemotron 3 Super: where it fits

NVIDIA's open 120B-total/12B-active hybrid Mamba-Transformer MoE built for high-throughput agentic reasoning at 1M-token context. Released March 11, 2026 by NVIDIA, it is built for high-throughput agentic reasoning (up to 2.2x GPT-OSS-120B), 1M-token context with strong long-context retrieval (91.6% RULER @ 1M), strong math reasoning (90.21% AIME 2025), and fully open weights, datasets, and recipes for self-hosting.

Its trade-offs are real: text-only; no image, audio, or video input, and requires roughly 8x H100-80GB GPUs to self-host at BF16. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

Microsoft Phi-4: where it fits

Microsoft's MIT-licensed 14B open model — strong reasoning for its size and very cheap, but a tiny 16K context and text-only. Released January 10, 2025 by Microsoft, it is built for strong reasoning for a small 14B open-weight model, mIT-licensed — fully self-hostable at no per-token cost, runs on modest or local hardware, and very cheap hosted inference at about $0.07/$0.14.

Its trade-offs: a tiny 16K context — by far the smallest window in this comparison, text only — no image, audio or video input, an early-2025 small model, outclassed on hard tasks by 2026 flagships, and no first-party per-token API; hosted prices are third-party. At $0.07 in / $0.14 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

NVIDIA Nemotron 3 Super and Microsoft Phi-4 overlap enough that the right pick depends on your specific job. NVIDIA Nemotron 3 Super costs less per token; NVIDIA Nemotron 3 Super holds the larger context; and each leads in its own area — NVIDIA Nemotron 3 Super for high-throughput agentic reasoning (up to 2.2x gpt-oss-120b), Microsoft Phi-4 for strong reasoning for a small 14b open-weight model. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is NVIDIA Nemotron 3 Super or Microsoft Phi-4 better for coding?

Public SWE-Bench figures are not available for Microsoft Phi-4, so the honest test is your own repository — run an identical real bug through both. By design, NVIDIA Nemotron 3 Super leans toward high-throughput agentic reasoning (up to 2.2x gpt-oss-120b) while Microsoft Phi-4 leans toward strong reasoning for a small 14b open-weight model, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, NVIDIA Nemotron 3 Super or Microsoft Phi-4?

NVIDIA Nemotron 3 Super is cheaper — Open weight (self-host / free) vs $0.07/$0.14 per 1M tokens.

Which has the bigger context window?

NVIDIA Nemotron 3 Super — 1M vs 16K, about 61× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both NVIDIA Nemotron 3 Super and Microsoft Phi-4 together?

Yes — a multi-model platform like LumiChats gives you NVIDIA Nemotron 3 Super, Microsoft Phi-4 and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, NVIDIA Nemotron 3 Super or Microsoft Phi-4?

NVIDIA Nemotron 3 Super — released March 11, 2026, about 14 months after Microsoft Phi-4.
