The article argues that while GPT-5.6 does not lead every benchmark, its tiered structure—Sol, Terra, and Luna—offers a superior cost-to-performance ratio for agentic tasks. For instance, Sol achieves high scores on coding benchmarks at half the price of Anthropic’s premium Fable 5, making it a practical choice for high-volume enterprise work.\n\nThe review highlights specific interface features that differentiate the product, such as Plan mode for pre-execution approval and Sites for generating live, interactive dashboards. It cites concrete examples from Zapier, NVIDIA, and Shopify, where teams report significant time savings and automated workflows, such as lead triage and data aggregation. Additionally, the piece notes OpenAI’s adoption of the Model Context Protocol (MCP), which allows seamless integration with over 35 enterprise vendors, including Salesforce and Adobe, reducing vendor lock-in.\n\nThe article also clarifies usage limits, noting that free tiers have strict message caps, while paid plans offer expanded access to reasoning models. It concludes that ChatGPT Work’s value lies not in being the \"smartest\" model, but in its ability to convert goals into finished outputs through robust tooling and integration capabilities.","keyPoints":["GPT-5.6 offers three tiers: Sol for hard tasks, Terra for balance, and Luna for high-volume work.","ChatGPT Work uses Plan mode and Sites to create interactive dashboards and approved multi-step workflows.","OpenAI adopted MCP, enabling integration with 35+ enterprise vendors like Salesforce and Adobe within 60 days."],"whyItMatters":"The shift from raw model intelligence to integrated workflow automation is critical for enterprise adoption.
