This issue covers news from March 17–18. OpenAI Releases GPT-5.4 Mini and Nano Source: https://openai.com/index/introducing-gpt-5-4-mini-and-nano Less than two weeks after GPT-5.4 dropped, OpenAI followed up with two smaller variants: GPT-5.4 mini and GPT-5.4 nano. Both target high-throughput workloads — faster responses, lower cost. GPT-5.4 mini approaches the full GPT-5.4 on several benchmarks and is a substantial step up from GPT-5 mini. Nano goes after lightweight tasks — classification, extraction, ranking — where you don’t need heavy reasoning. Both models support GPT-5.4’s tool calling and structured output capabilities.
