From Oct 15 it lets ChatGPT read every open tab\n(Chat mode) and act inside them (Work mode), using the sites the user is already signed in to. Tasks include sending messages,\nfilling out forms and downloading files. It runs through the ChatGPT desktop app and also works in other Chromium browsers.\nOpenAI's documentation describes per-site permission prompts, an allowlist and blocklist under Settings > Computer Use, and an\nelevated-risk warning for blanket site access and for reading browsing history.\n\n## Why it matters\n\nOpenAI dropped its own browser (Atlas, retired in August) and moved computer use into the browser most people already use, with\ntheir logged-in sessions. That puts an agent in front of email, banking and work tools. In the same week JPMorgan said it will not\nlet outside agents operate customer accounts. Agent access to logged-in sessions is also where prompt-injection attacks have\ndone the most harm.","disputed":[],"related":[{"id":"2026-09-29-openai-devday-2026","url":"https://postcutoff.com/e/2026-09-29-openai-devday-2026/","date":"2026-09-29","date_precision":"day","short_title":"OpenAI DevDay 2026 brings dots agents, GPT-6.1 Sol, Ultrafast and a $500 Pro plan","deck":null,"takeaway":"DevDay marks OpenAI's shift from chat and coding tools toward persistent, proactive agents (dots), and toward ChatGPT as a workspace platform (Space, Pages, plugin extensions, Marketplace).","category":"product","category_label":"Products","importance":4,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":37,"official":20,"filed":"2026-09-29","updated":"2026-10-07","orgs":["OpenAI"]}],"people":[],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-10-16","type":"filed","text":"Created (OpenAI docs and Unite.AI read; OpenAI's X posts not opened)"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-16","run":null,"sources_read":"OpenAI docs and Unite.AI read; OpenAI's X posts not opened","updated":"2026-10-16","human_review":null,"version":{"date":"2026-10-16"}},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":168,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":107,"in_training_data":false},{"model_id":"gemini-4-argon","name":"Gemini 4 Argon","cutoff":"2026-03","days_after":198,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":137,"in_training_data":false}],"short_url":null}
