OpenAI said the new family is tiered by capability and use case, with Sol as the flagship model focused on coding<\/strong>, Terra for higher-volume enterprise tasks, and Luna as an entry-level option for lighter workloads.<\/p>\n\n\n\n OpenAI CEO Sam Altman told CNBC that Sol delivered a 54 percent improvement in token efficiency on coding tasks<\/strong>. OpenAI also cited results from the Artificial Analysis Coding Agent Index, saying Sol scored 80 on that benchmark, 2.8 points higher than Anthropic’s Fable 5, while producing fewer than half the output tokens, taking less than half the runtime, and costing about one third as much.<\/p>\n\n\n OpenAI said Terra’s performance sits slightly above Fable 5, and that Luna surpasses Opus 4.8. The company described GPT-5.6 as its most capable cybersecurity model to date, saying it supports threat modeling, code review and remediation, and blue-team exercises for defensive security work.<\/p>\n\n\n\n Pricing is per one million tokens. Sol is priced at $5 per million input tokens and $30 per million output tokens (originally HK$234, about $29.86 when converted at 0.1276). Terra is $2.50 per million input tokens and $15 per million output tokens. Luna is $1 per million input tokens and $6 per million output tokens.<\/p>\n\n\n\n OpenAI also introduced ChatGPT Work, a companion tool for desktop, web and mobile that the company said will help users draft documents, build spreadsheets and prepare presentations. For developers and enterprise teams that process large volumes of code and documents, the tiered pricing is designed to let customers match cost to task complexity.<\/p>\n\n\n The GPT-5.6 launch comes as OpenAI announced it will shut down the Atlas AI browser, which the company launched less than a year earlier, and migrate the browser’s agented browsing features into desktop apps and a Chrome extension.<\/p>\n\n\n\n OpenAI also confirmed that senior executive Fidji Simo resigned for health reasons. The company said the moves reflect a period of product consolidation even as it expands its core model lineup, and that Sol, Terra and Luna are available now through ChatGPT and the OpenAI API.<\/p>\n\n\n\n Industry analysts said the arrival of GPT-5.6 will intensify competition among leading developer-oriented models, with OpenAI positioning Sol to capture coding workloads and its security capabilities to address enterprise concerns about adversarial misuse.<\/p>\n\n\n\n OpenAI did not immediately provide public benchmarks for every enterprise workload, and the company declined to comment beyond its published statements and the briefing with CNBC.<\/p>\n\n\n\n For developers and IT teams, OpenAI said documentation and SDK support for GPT-5.6 are available in the developer portal, and that migration guides will help customers move existing Codex or earlier GPT workloads to the new family.<\/p>\n\n\n\n Reporting for this story relied on OpenAI’s announcement and a CNBC interview with Sam Altman.
