Northeast Securities reviews OpenAI's GPT-6 Astra, released September 3, 2026, priced at $10/$1/$50 per million tokens for input/cache-read/output — 2.5x the prior GPT-5.6 Sol promotional price — while context stays at 1.05 million tokens across three generations. The upgrade concentrates in task execution: OSWorld 2.0 rises from 65.7% to 72.6%, average task time compresses from ~75 to ~40 minutes, unauthorized actions on undoable tasks drop from 48% to 0, and FrontierMath Tier 4 improves from 83.0% to 97.6%. ScreenSpot-Pro UI-grounding accuracy reaches 92.7%; AutomationBench cross-application success climbs from 18.1% to 41.4%. Per-task cost rises only from $1.99 to $3.26 — below Claude Opus 5's $5.86 and Claude Fable 5.1's $7.63 — as Astra scores 53 on the Artificial Analysis intelligence index, level with Claude Fable 5.1. Computer Use lets models operate desktops directly without vendor APIs, opening closed workflows and shifting the business model from selling tools to selling outcomes, with token pricing giving way to task pricing. Pre-training on 100,000-plus GPUs, one of OpenAI's largest runs, plus rising inference needs lifts domestic compute demand. The sector rating stays Outperform; beneficiary chains span foundation models and workflows, compute leasing, AI marketing and multimodal content, with only Xunce, Marketingforce, Mobvista and COL Digital under coverage.
