OpenAI released GPT-5.4 in Standard, Thinking, and Pro variants. Headline capabilities: native computer-use (75.0% on OSWorld-Verified, surpassing human 72.4%), 1M token context, and first-ever "compaction" support for longer agent trajectories. The Tool Search API is the builder-critical feature: models look up tool definitions on demand instead of loading all schemas upfront, reducing token usage by 47%. This directly addresses the context overhead problem — Claude Code hauls 62,600 characters of tool definitions per turn (55% of context), while Tool Search would let models query tools as needed. Benchmarks: 83.0% GDPval (vs Opus 4.6's 78.0%), 57.7% SWE-Bench Pro, 89.3% BrowseComp (Pro variant). GPT-5.2 deprecated in 3 months. (OpenAI | TechCrunch)
