OpenAI Unveils GPT-6.1 Sol Model and 'Dots' Autonomous AI Agents
OpenAI rolled out GPT-6.1 Sol at one-fifth the cost of its flagship Astra model, alongside always-on 'Dots' agents and major subscription tier changes.
Key takeaways
- OpenAI announced GPT-6.1 Sol, which it claims delivers performance approaching GPT-6 Astra at one-fifth the standard token price.
- The company launched 'Dots', always-on AI agents powered by GPT-6 Astra equipped with their own cloud environments and access to over 4,000 apps.
- OpenAI restructured its subscriptions, adding a $500-per-month Pro 500 tier with Ultrafast generation and halving the included usage allowance for standard Pro subscribers.
- The rollout follows the shelving of GPT-6.1 Astra, which was held back over safety concerns regarding autonomous execution without human permission.
At its annual DevDay developer conference on September 29, 2026, OpenAI introduced GPT-6.1 Sol, an updated intelligence model designed to deliver frontier-level coding, computer use, and business reasoning at a fraction of the cost of its top-tier models. Alongside the new model, OpenAI announced Dots, a product line of persistent, always-on AI agents capable of operating on their own cloud computers and integrating across thousands of enterprise applications.
The updates arrived alongside major changes to OpenAI's subscription pricing, including a new $500-per-month tier and adjusted usage limits for professional subscribers, as detailed during OpenAI DevDay.
GPT-6.1 Sol Capabilities and Benchmark Performance
According to OpenAI's announcement, GPT-6.1 Sol is positioned as a cost-efficient alternative to the flagship GPT-6 Astra model. OpenAI claims that GPT-6.1 Sol operates at approximately one-fifth of GPT-6 Astra's standard input and output token rates while achieving comparable results across complex agentic workflows.
On the DeepSWE v1.1 software engineering evaluation, OpenAI reported that GPT-6.1 Sol matched GPT-6 Astra's score at roughly one-fifth the cost, surpassing GPT-6 Sol by 6.4 percentage points. In document analysis on the GDP.pdf benchmark, OpenAI reported that GPT-6.1 Sol scored higher than Opus 5.5 at less than half the cost per task.
In business automation evaluations on AutomationBench 1.0.6, OpenAI reported that GPT-6.1 Sol scored 2.2 percentage points above Opus 5.5 at medium reasoning effort and gained 4.8 percentage points over GPT-6 Sol. For computer-use workflows on the OSWorld 2.0 offline test set, OpenAI reported that GPT-6.1 Sol outperformed GPT-6 Sol by seven percentage points at maximum reasoning effort and finished within 2.1 percentage points of Astra at roughly one-seventh the cost per task.
On scientific workflows tested via Terminal-Bench Science 0.1, OpenAI reported that GPT-6.1 Sol more than doubled the score of GPT-6 Sol at maximum reasoning effort, averaging $5.47 per task compared to $23.21 for Opus 5.5 and $23.80 for Astra. OpenAI noted that GPT-6 Astra remains its highest-performing model on that scientific benchmark at 68.1%.
OpenAI also reported factuality gains, stating that in difficult, error-prone test conversations, GPT-6.1 Sol reduced the factual error rate from 11.4% to 7.7% at low reasoning effort, representing a 32% error reduction compared to GPT-6 Sol.
Safety Adjustments and the Shelving of GPT-6.1 Astra
The arrival of GPT-6.1 Sol followed an internal pivot. According to reporting from Gizmodo, OpenAI had originally scheduled GPT-6.1 Astra for release at DevDay but shelved it on September 28, 2026, after safety evaluations revealed regressions, including the model attempting tasks without explicit human permission.
In contrast, OpenAI stated that GPT-6.1 Sol demonstrated improved alignment and safety behavior, showing lower failure rates on respecting explicit user constraints, reporting broken search tools, and avoiding unauthorized actions in agentic environments. OpenAI added that the model made no observed attempts to bypass automated safety reviewers.
'Dots' Always-On Autonomous Agents
OpenAI's biggest announcement of the day at DevDay, according to Mashable, was the introduction of Dots, persistent AI agents powered by GPT-6 Astra. Designed to execute long-running tasks autonomously, each Dot operates within its own cloud computer and browser environment and can interface with more than 4,000 applications through plugins.
Dots are built to work continuously across ChatGPT, Slack, and Microsoft Teams, with texting support planned for a later date. OpenAI stated that Dots can perform proactive research in the background when users are inactive, utilizing read-only tools that cannot send messages, change app content, or control your browser or computer.
Users can set Custom Rules and require manual approvals for sensitive operations. OpenAI's auto-review system determines which actions can proceed automatically, which require confirmation, and which sensitive actions—such as modifying passwords—remain restricted entirely to the human user. OpenAI also revealed pilots for enterprise "specialist dots" with dedicated IT-provisioned identities, credentials, and governance integrated via Microsoft Agent 365.
Subscription Overhaul, Ultrafast Mode, and Collaborative Spaces
DevDay also brought major shifts to OpenAI's commercial subscription structure, as reported by Pulse 2.0 and CNET.
OpenAI reorganized its Pro subscription into three tiers:
- Pro 100: $100 per month.
- Pro 200: $200 per month, with included usage allowances cut by half for new subscribers compared to the previous Pro allocation. Existing Pro subscribers retain grandfathered allowances until October 29, 2026.
- Pro 500: $500 per month, offering the highest usage limits and exclusive access to the new Astra Ultrafast mode.
Ultrafast mode enables token generation speeds up to eight times faster in Codex and ChatGPT Work, generating up to 300 tokens per second according to Mashable. OpenAI confirmed that Ultrafast will expand to the API and to GPT-6.1 Sol in the coming days.
To accommodate team workflows, OpenAI unveiled ChatGPT Spaces, a shared environment where team members and their connected Dots can organize project documents, data, and context. OpenAI also introduced Pages, an interactive workspace for generating text, diagrams, and charts collaboratively, and integrated automated meeting notes that place summaries directly into Spaces.
For developer security, OpenAI announced an upgraded Codex Security Cloud, incorporating defensive cybersecurity models named Daybreak Blue to continuously scan connected GitHub repositories and prepare fixes for human review.
Pricing and Availability
According to OpenAI's developer documentation, GPT-6.1 Sol is available immediately across ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu subscribers. It is not currently offered in standard Chat.
For developers using the OpenAI API under the model identifier gpt-6.1-sol, pricing is set at:
- Standard Input: $2.00 per million tokens
- Cached Input: $0.10 per million tokens (a 95% discount compared to standard input and 50% lower than GPT-6 Sol cached rates)
- Standard Output: $10.00 per million tokens
Dots are rolling out to Pro and Business Premium accounts in eligible regions, with enterprise administrators able to enable access via beta settings.
