OpenAI Introduces GPT-5.4 Mini And Nano
OpenAI on 17 March 2026 introduces GPT-5.4 mini and GPT-5.4 nano, extending the GPT-5.4 family released two weeks prior. OpenAI’s self-reported benchmarks show the nano outperforms the prior mini at maximum reasoning and the mini is two times faster; published pricing lists the nano at $0.20 input and $1.25 output, undercutting Google’s Gemini Flash-Lite. The company also released llm 0.29 and shared a user cost example for bulk photo descriptions.
Key Points
- 1Announces GPT-5.4 mini and nano, alongside GPT-5.4, with nano outperforming the prior mini
- 2Highlights performance and efficiency: nano beats previous mini at max reasoning and mini is 2x faster
- 3Offers lower-priced inference: nano's per-token pricing undercuts Gemini Flash-Lite, reducing large-scale image costs
Scoring Rationale
High practical impact from lower-cost, efficient LLM variants; limited novelty since changes target size/performance trade-offs rather than core capabilities.
