AI Model Profile
GPT-5.4 nano
GPT-5.4 nano is an earlier model for simple high-volume tasks. It is deprecated, with API shutdown scheduled April 1, 2027; the recommended replacement is gpt-6-luna.
Before you buy
Best for: High-volume classification, extraction, routing, and lightweight assistant tasks where cost matters.
Price: USD API: US$0.20 input / US$1.25 output per 1M tokens
Included: GPT-5.4 nano is an earlier model for simple high-volume tasks. It is deprecated, with API shutdown scheduled April 1, 2027; the recommended replacement is gpt-6-luna.
Main limits: Small models need task-specific evals because low cost can trade off with reliability on complex prompts. Standard list rates; cache writes, tools, long-context premiums, regional processing and other service tiers can change the bill.

Benchmark Caveat
Benchmarks and provider capability notes are directional, not universal rankings. Results can shift with prompts, tool use, latency targets, pricing tier, safety filters, context length, and the workload mix a real team runs.
See the linked official model, docs, model-card, or pricing source for provider-published capability notes.
Best for
High-volume classification, extraction, routing, and lightweight assistant tasks where cost matters.
Skip if
Skip if the workload needs deep reasoning, long-form synthesis, or maximum coding reliability.
Strengths
OpenAI positions the nano tier for lower-cost GPT-5.4-class workloads.
Weaknesses
Small models need task-specific evals because low cost can trade off with reliability on complex prompts.
Agent suitability
Useful for agent workflows when the provider supports tool use, long context, structured outputs, or workflow-specific APIs.
Kingy AI take
Use this as a source-backed shortlist candidate, not a universal ranking. Re-check official provider docs and run a task-specific trial before production adoption.
