GPT-5.4 mini is OpenAI's high-volume workhorse, released 2026-03-17 alongside GPT-5.4 nano — the "most capable small model" OpenAI had shipped, built explicitly for the subagent era. It nearly matches full GPT-5.4 on coding (SWE-bench Pro 54.4% vs base 57.7%) at roughly one-third the cost, with a full tool surface including computer use that is rare at this price. The one-sentence buyer's take: for cost- and latency-sensitive workloads that still need strong reasoning and tool use, this is the default mini-tier choice in the OpenAI lineup as of 2026-05-28. - Provider: OpenAI - Release: 2026-03-17 - Status: GA - Context: 400,000 tokens - Max output: 128,000 tokens - Modalities: text + image in, text out - Knowledge cutoff: 2025-08 - Headline price: $0.75 in / $4.50 out per 1M tokens
Full review →GPT-5.4 nano is OpenAI's lightweight workhorse, released 2026-03-17 — the cheapest model in the GPT-5.4 frontier family, built for the highest-volume, lowest-latency workloads. Despite being four tiers below the flagship, it beats the previous-generation GPT-5 mini on SWE-bench Pro (52.4% vs 45.7%) and matches it on GPQA Diamond (82.8%). The one-sentence buyer's take: indispensable as the bottom tier of a routed architecture — classification, extraction, triage, and routing at a price that competes with embedding pipelines. - Provider: OpenAI - Release: 2026-03-17 - Status: GA - Context: 400,000 tokens - Max output: 128,000 tokens - Modalities: text + image in, text out - Knowledge cutoff: 2025-08 - Headline price: $0.20 in / $1.25 out per 1M tokens
