The Codex harness, the toolkit that runs OpenAI's coding agent and its new dots, is now open source, and its hosted version just gained the ability to click and type like a person.

OpenAI made the Codex harness open source on September 29, so developers can inspect and reuse the same code that powers Codex, ChatGPT Work, and dots. Its hosted counterpart, the Agents API, added computer-use support, letting an agent operate software directly, plus Codex's multi-agent delegation and tool search.

The Agents API itself launched in public beta earlier, on September 10; the computer-use and multi-agent additions are what's new at DevDay. It's available through the API, and in Codex and ChatGPT Work on the Pro 500 and Enterprise plans.
Key Capabilities:

• Open harness: The Codex CLI, SDK, and app server are public on GitHub.
• Computer use added: Agents can now click, type, and navigate software directly.
• Managed hosting: OpenAI runs the infrastructure, so developers don't host it themselves.

Teams can now work inside ChatGPT itself, on shared pages and slides both people and their dots can edit together, instead of switching to Docs or Slack.
OpenAI launched ChatGPT Space on September 29, a shared workspace for Pro, Business, and Enterprise users. Its core feature, Pages, is an interactive document with charts, checklists, and dashboards that a team, ChatGPT, and a user's dot can all edit. Slides and Sheets are coming later.
Each collaborator uses their own ChatGPT account, so private chats stay separate even on a shared page. Editing works on desktop and web now; mobile can view and share, but not yet create pages.
Key Capabilities:

• Live pages: Interactive documents with charts and dashboards, not static text.
• Human and agent editing: Both teammates and their assigned dots can update the same page.
• Team plugin sharing: Business and Enterprise tiers add shared plugins and scheduled tasks.

The new /visualize command lets developers generate charts and diagrams inline while chatting with a coding agent, without leaving the interface.
Cursor released /visualize for its Agents Window, letting users point an agent at a file, query, or log and get a rendered chart or diagram back in the chat. It builds on Cursor's earlier Canvas feature, which let agents create dashboards with reusable chart and table components.
The command needs no separate setup or added cost. Developers say it's useful for quickly checking a metric or sketching a system diagram mid-conversation, rather than switching to another tool.
Key Capabilities:

• No setup: Works immediately in the Agents Window for all Cursor users.
• Multiple sources: Can visualize data from files, queries, logs, or connected tools.
• Builds on Canvas: Uses the same React-based chart and diagram components as Cursor's Canvas feature.

After OpenAI unveiled its "dots" agent, people noticed dot.com belongs to Elon Musk's xAI and redirects to the Grok Bot download page.
OpenAI announced dots on September 29. Soon after, users found that dot.com, transferred to xAI in July according to WHOIS records, sends visitors to Grok Bot instead of anything OpenAI-related. xAI has not commented, and no evidence confirms it knew OpenAI's product name in advance.
The domain could simply catch typos of "bot.com," which xAI does not own either, feeding the prank theory. The closer match, dots.com, belongs to a defunct clothing retailer and is unrelated to either company.
Key Capabilities:

• Confirmed fact: dot.com redirects to Grok Bot's download page as of September 29.
• Confirmed fact: WHOIS records show the domain transferred to xAI in July, two months before OpenAI's launch.
• Unconfirmed: Whether the timing was intentional; neither company has said so.

Released alongside dots, GPT-6.1 Sol offers close-to-Astra intelligence at a fraction of the price, replacing the week-old GPT-6 Sol.
OpenAI launched GPT-6.1 Sol on September 29, just seven days after GPT-6 Sol. Independent tracker Artificial Analysis says it scores one point below GPT-6 Astra on its Intelligence Index at under a quarter of the cost per task, with pricing unchanged at $2/$10 per million input/output tokens.
The fast replacement cycle shows OpenAI iterating quickly on its cheaper tier while its top model, GPT-6.1 Astra, stayed unreleased after failing internal safety checks.
Key Capabilities:

• Near-flagship score: Just one point below GPT-6 Astra on Artificial Analysis's Intelligence Index.
• Lower cost: Rated at under 25% of GPT-6 Astra's cost per task.
• Bigger cache discount: The cache-read discount rises above the 90% GPT-6 Sol offered.

Unveiled at DevDay 2026, dots run continuously inside ChatGPT on OpenAI's flagship GPT-6 Astra model, connecting to over 4,000 apps to keep working between conversations.
OpenAI launched dots on September 29, powered by GPT-6 Astra. Each dot gets a persistent cloud computer and browser, works through Slack, Teams, or ChatGPT, and can act on saved logins without exposing passwords to the model. Sensitive actions still need approval by default.
Dots are rolling out to Pro and Business Premium users in eligible markets, but not yet to Pro users in the EEA, Switzerland, or the UK. OpenAI also released the cheaper GPT-6.1 Sol the same day, after quietly canceling GPT-6.1 Astra over safety test failures.
Key Capabilities:

• Persistent memory: A dot keeps context and learns from feedback across sessions, not just one chat.
• App reach: Connects to more than 4,000 apps through plugins.
• Built-in guardrails: Follows ChatGPT's existing permissions, with custom rules for what needs human sign-off.
