3-Line TL;DR

  • This was a substantial DevDay, with improvements to the model, the tools that execute work, and the places where people share the result
  • OpenAI's official recap has 25 named announcements, covered below from Sol and Dots to developer APIs, plugins, collaboration, subscriptions and enterprise purchasing
  • GPT-6.1 Sol is still my personal highlight, but the larger appeal is how much more work the whole setup can handle, with some features live and others in preview or still coming

Sol makes everyday work more interesting; Ultrafast buys speed

  • GPT-6 Sol left me disappointed, and Astra feels expensive to run casually, so a more capable everyday model is exactly the update I wanted
  • OpenAI reports GPT-6.1 Sol improving DeepSWE 1.1 by 6.4 percentage points over the previous Sol's best result, and AutomationBench by 4.8 points at medium effort
  • These are maker-reported coding and business-workflow evaluations, which give me a reason to try it rather than a hands-on verdict (Sol announcement)

Standard input and output token prices for GPT-6 Sol, GPT-6.1 Sol and GPT-6 Astra

Model Input Cached input Output
GPT-6 Sol $2 $0.20 $10
GPT-6.1 Sol $2 $0.10 $10
GPT-6 Astra $10 $1 $50

Sources: official model docs for GPT-6 Sol, GPT-6.1 Sol and GPT-6 Astra; USD per million text tokens, standard API processing, checked September 29, 2026

  • Sol 6.1 keeps the ordinary rates and halves cached-input pricing, with standard input and output at one-fifth of Astra's rates
  • The table uses requests with at most 272K input tokens and excludes tools and processing premiums; above that threshold the full request has double input/cache rates and 1.5 times output rates
  • Token rates do not guarantee the same saving per finished task, which I explore in the Sol versus Opus and Sonnet comparison
  • Sol 6.1 launches in Work, Codex and the API for the listed paid plans, while ordinary Chat support is still pending
  • Ultrafast adds premium speed, with OpenAI advertising up to 8× token generation in Codex, reaching 300 tokens/second, and up to 6× in the API (Launch recap)
  • Astra Ultrafast is available in the API and in Work/Codex on Pro 500 and Enterprise, while Sol 6.1 Ultrafast is coming later
  • The API has its own pricing and rate limits, so this is a speed option for work where waiting costs enough to justify it (Ultrafast docs)
  • A faster answer is useful, although I would still prefer not to buy faster corrections

Dots gives ongoing work somewhere to continue

  • Dots are Astra-powered agents with their own cloud computers, persistent context and access to connected apps, reachable through ChatGPT, Slack or Teams (Dots announcement)
  • The point is being able to keep a project moving across conversations instead of explaining the same background every morning
  • Availability begins with Pro and Business Premium in eligible markets, with an admin-enabled beta for Enterprise, Edu and Healthcare
  • Background proactive research is read-only, while actions follow permissions and approval rules
  • OpenAI is also piloting specialist dots with organizational identities and working on Microsoft Agent 365 integration
  • I like the direction, provided the agent brings back useful progress instead of another queue of things to approve
  • Dots conversations do not count against ChatGPT usage, but Work and Codex tasks they start still consume the usual allowance

Codex and the APIs got a full working-tool update

Announcement What changes Rollout or practical limit
Codex in the cloud Reusable development environments and remote work from other devices Paid plans; repositories, tools and permissions still need setup
Refreshed Codex CLI Voice steering, an /agents view, and better prompt editing, session resuming and worktrees Announced for all plans
Code Review A desktop review inbox, diffs and cloud reviews while away GitHub support available; GitLab review integration remains in preview
Codex Security Cloud Repository scans, new-commit monitoring, investigated findings and proposed fixes Pro and organizational plans; includes Daybreak Blue model access without a separate application
Decisions API Luna answers bounded questions for classification, routing or an agent's next step Limited preview, broader release planned in the coming days
Agents API with computer use Add browser interaction to managed agents alongside multi-agent execution, tools and context compaction API access; computer use also announced for Pro 500 and Enterprise in Work/Codex
Bedrock Managed Agents OpenAI agent execution integrated with AWS resources and infrastructure Limited preview; inference and data remain inside AWS
  • This is a large part of why the event felt useful to me: writing code, running it, reviewing it and maintaining it all received attention
  • Decisions API is the routing-related announcement I meant, with predefined answers rather than a promise of automatic Sol/Astra switching inside Codex
  • Codex already feels quick to bring new capabilities into the workflow, and this batch strengthens that impression
  • Its integrated gpt-image-2 generator is another personal favorite, although it is an existing feature rather than a new image-model launch at this DevDay (Image generation)
  • Moving between writing, code and images in one place matters to me more than another isolated demo

Plugins are becoming part of the interface

Announcement What it enables Rollout or practical limit
Plugin extensions Sidebar destinations, interactive panels and custom file viewers Web support for Free/Go is still coming; composer mentions are desktop-only
Plugin creation, submission and discovery Plugin Creator, clearer submission feedback and improved recommendations Broad rollout; users still approve each plugin's access
Plugins hosted in Sites Shared apps that use each visitor's own connected data and permissions, plus easier automations The new plugin-hosting announcement targets Business, Enterprise, Healthcare and Edu
MCP events Start automations when a connected app reports a change Based on the proposed events specification; requires a supporting integration
  • A project-board update can now be the trigger for work, rather than another item someone has to copy into a prompt
  • Connected-app access for Site visitors is read-only and requires approval; it cannot be reused by background scheduled tasks (Enterprise release notes)
  • This is more interesting than adding another chat command because the connection can become part of the actual app people use

Space, Pages and meetings make the team side substantial too

Announcement What it adds Rollout or practical limit
ChatGPT Space Shared context for people, ChatGPT and dots Pro, Business and Enterprise; mobile starts with finding, reading and sharing
Pages Living documents with text, research, visuals and collaborative editing Creation and editing on web and desktop; mobile editing coming later
Collaborative slides Teammates and agents edit the same deck, with PowerPoint and Google Slides export planned Coming in the next few weeks, rather than universally available at launch
Teams and Team Tasks Shared work and recurring tasks triggered by a schedule or event Business and Enterprise, under workspace permissions
@ChatGPT in Slack and Microsoft Teams Work together with ChatGPT inside a channel, thread or DM Admin setup; colleagues need no separate individual ChatGPT license
Meetings plugin Personalized notes and action items saved in Space, ready for follow-up work macOS beta for Pro/Business; other platforms and broader Enterprise support still coming
  • The appeal is that the discussion, document and follow-up task can share context instead of arriving as three unrelated copies
  • Meetings deletes audio after notes are ready, so it is not a recording archive you can replay later
  • Fewer notes to type would be welcome; I am less convinced that anyone needs help scheduling more meetings
  • Space also replaces Library for the eligible plans, while collaborative spreadsheets are listed as coming soon on its product page

The subscription and enterprise announcements matter as well

Announcement What it changes Rollout or practical limit
Shareable profiles A place to showcase creations such as Sites and plugins Web/desktop showcase; help docs say Enterprise profiles are still coming
Sign in with ChatGPT Use a ChatGPT identity and, where supported, Plus/Pro usage in partner tools Plan usage is shared, with per-app limits; partners may charge separately
Pro 500 A $500/month tier with Astra Ultrafast and the highest included usage Available now; the launch describes 25× the Plus allowance
OpenAI Marketplace Put part of an eligible enterprise OpenAI commitment toward approved partner software Enterprise eligibility and partner terms apply
Private Intelligence Private Safety Processing for automated safety review without human access to protected content Private Inference, using confidential computing, is a separate preview planned for this fall
  • The sign-in launch names 16 usage partners, including Devin, Notion, Vercel, T3, OpenClaw and Dactyl, while Marketplace starts with 32 partners including Adobe and Figma (Full announcement list)
  • External plan usage is particularly appealing because it lets the same subscription support more of the tools I already use
  • It also means several apps can spend the same allowance, which is a good reason to set limits before introducing them to each other
  • My overall verdict is that this DevDay was packed with useful changes, with Sol as my first experiment and the broader workflow improvements giving it somewhere useful to work
  • Some features are rolling out gradually or depend on plan, region and admin settings, so a launch announcement does not mean every account has every switch today

Community Reactions

  • In the Sol launch discussion, one reader sees a competitive option if the advertised improvements hold up (Reddit)
  • Another cautions that being near Astra does not establish equality across benchmarks (Reddit)

Q&A (Field Notes)

  • Q. Is everything listed available now?
    • No, Sol Ultrafast, collaborative slides, mobile page editing and Private Inference are still ahead, while Decisions API and Bedrock Managed Agents start in limited preview
  • Q. Is Dots an unlimited Astra subscription?
    • No, conversations and executed work have different accounting, and Work/Codex tasks still use the normal allowance
  • Q. Does Sign in with ChatGPT make partner apps free?
    • No, eligible AI use can draw from Plus/Pro, while the partner may still charge for its own service
  • Q. What would I try first?
    • Sol on work that disappointed me with GPT-6 Sol, followed by Codex cloud/review and one narrowly defined Dots responsibility
  • Q. Was a new image-generation model announced?
    • The integrated image generator is part of why I like the workflow, but this recap does not establish a new image-model release
