OpenAI held DevDay 2026, announcing Dots (personal AI agents available 24/7), ChatGPT Space (a workspace for humans and agents), GPT-6.1 Sol (a cost-efficient model), new subscription tiers including a $500 Pro plan, Decisions API for structured decision-making, and expanded cloud Codex features with reusable environments.
GPT-6.1 Sol replaces GPT-6 Sol after seven days, achieving near-Astra intelligence levels with a score just 1 point below GPT-6 Astra while costing less than one quarter per task. Pricing remains at $2/$10 per million tokens with improved cache discounts, delivering significant gains across benchmarks including an 8-point jump in AA-Omniscience Accuracy and a 12-point improvement in Terminal-Bench 4.0.
