Price: USD API: US$0.75 input / US$4.50 output per 1M tokens
Included: GPT-5.4 mini is an OpenAI API model described as a smaller model for coding, computer use, and subagents.
Main limits: This profile does not claim it matches larger frontier models; benchmark and quality checks should be task-specific. Standard list rates; cache writes, tools, long-context premiums, regional processing and other service tiers can change the bill.

Benchmark Caveat
Provider documentation and provider-published capability notes are directional, not universal rankings. Real results depend on prompts, tools, latency targets, pricing tier, safety filters, context length, and workload mix.
Best for
Candidate for lower-latency or lower-cost OpenAI API workflows that still need coding and tool-use support.
Skip if
Skip if your team needs independently benchmarked performance claims or contractual guarantees not present in the official provider documentation.
Strengths
Official docs list tool support, 400K context, and lower listed API price than larger GPT-5 models.
Weaknesses
This profile does not claim it matches larger frontier models; benchmark and quality checks should be task-specific.
Agent suitability
Candidate for subagents and computer-use workflows where cost and speed matter.
Kingy AI take
Use this profile as a source-backed reference point, not a ranking. Re-check official provider docs before making production or budget decisions.
