OpenAI GPT-5.5 Agent Model Dey Take Over ChatGPT, E Cut Tokens but API Costs Don Increase

OpenAI release GPT-5.5 agent model for April 23, 2026, wey replace GPT-5.4 as default for ChatGPT for Plus, Pro, Business, and Enterprise users. GPT-5.5 dey positioned as an “agentic” system wey fit finish messy, multi-step real work with less step-by-step human guidance. Dem also get GPT-5.5 Pro variant wey dey target longer-horizon, higher-accuracy workloads. Key performance claims for the rollout include 82.7% on Terminal-Bench 2.0, 84.9% on GDPval across 44 knowledge-work occupations, and 78.7% on OSWorld-Verified for autonomous operation for real computer environments. OpenAI talk say GPT-5.5 agentic model keep the same per-token latency as GPT-5.4, but e use fewer tokens for same tasks, and dem reframe quality from “chat” metrics to execution outcomes. Pricing dem set for agent deployments: standard GPT-5.5 na $5 per million input tokens and $30 per million output tokens, while GPT-5.5 Pro dey expected at $30/$180 per million input/output. OpenAI still compare well with Anthropic’s Claude Mythos Preview on Terminal-Bench 2.0 and say GPT-5.5 remain inside their critical cybersecurity risk threshold (“High”), so e need enhanced safeguards. For crypto traders, direct impact on coin prices likely small. But the push toward AI agents for enterprise workflows fit shift sentiment around AI infrastructure and the wider “digital economy” story—usually a second-order driver rather than immediate catalyst.
