Phi 4 model profile
Evidence snapshot:
Phi 4 is a Microsoft model profile with a 16,384-token context window. The dated catalog snapshot records text modalities and interfaces for structured output, text generation.
Microsoft Research Phi-4 is designed to perform well in complex reasoning tasks and can operate efficiently in situations with limited memory or where quick responses are needed. At 14 billion...
Phi 4 is a reference profile: Microsoft publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Phi 4 is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.
Phi 4 accepts text and returns text. The snapshot records structured output and text generation as capabilities or interfaces.
The dated reference snapshot lists $0.07 input and $0.14 output per million tokens.
No comparable third-party benchmark value is present in the 2026-09-06 snapshot. Missing values are not estimated.
No comparable popularity rank or traffic share is present in the 2026-09-06 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated.
Profile data was reviewed for the 2026-09-06 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.

When to pick Phi 4
Phi 4 is a reference profile: Microsoft publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Each condition below is derived from this model's own values in the 2026-09-06 snapshot, compared only against models publishing the same field.
- Reach for it when cost is the binding constraint. At $0.07 in and $0.14 out per 1M tokens, combined token price sits in the cheapest quarter of the 146 models publishing both rates in this snapshot.
- Look elsewhere when you need to call it through Kendr today. This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr.
- Look elsewhere when the prompt is long. The 16K-token context window is in the bottom quarter of the 163 models publishing a limit. Long documents need chunking or a wider-context route.
- Look elsewhere when you are building an agent. No tool-calling capability is recorded for this model in the snapshot. Agent loops need a route that can call functions.

Dated pricing snapshot
The dated reference snapshot lists $0.07 input and $0.14 output per million tokens.
These are dated third-party reference prices, not Kendr prices or an availability offer. Routes, tiers, caching, region, and provider policy can change the landed price.

Frequently asked questions
When should I use Phi 4?
Phi 4 is a reference profile: Microsoft publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call. Reach for it when cost is the binding constraint: At $0.07 in and $0.14 out per 1M tokens, combined token price sits in the cheapest quarter of the 146 models publishing both rates in this snapshot. Look elsewhere when you need to call it through Kendr today: This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr. Look elsewhere when the prompt is long: The 16K-token context window is in the bottom quarter of the 163 models publishing a limit. Long documents need chunking or a wider-context route.

What is Phi 4?
Phi 4 is a Microsoft model profile with a 16,384-token context window. The dated catalog snapshot records text modalities and interfaces for structured output, text generation.
What context window does Phi 4 have?
The dated profile lists 16,384 tokens of context and up to 14,745 output tokens. Provider routes, variants, and runtime configuration can impose lower effective limits.
What benchmark evidence is available for Phi 4?
No comparable third-party benchmark value is present in the 2026-09-06 snapshot. Missing values are not estimated. Third-party catalog fields normalized from the cited model dataset; benchmark methodology and coverage differ by source.
Is Phi 4 available through Kendr?
This is an independent knowledge profile, not a Kendr-hosted availability claim. Check Kendr's live public model API for currently enabled Kendr aliases.
Does the popularity rank represent Phi 4's global market share?
No comparable popularity rank or traffic share is present in the 2026-09-06 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated.
