The dimensions that change the decision.
Not established from the available sources.
Voice modality supportChatGPT Voice runs on GPT‑6 Sol (alongside Astra and Luna), enabling voice interactions and access to plugins like email, calendar, and Slack in that feature.
Benchmark and cost comparisons vs. Anthropic (reported)Reports claim GPT‑6 (Sol) delivers results similar to Anthropic’s Claude Opus 5 on a computer‑use benchmark (OSWorld 2.0) at roughly 80% lower cost, and that on AutomationBench GPT‑6 Sol at its highest effort level beats Claude Opus 5 at maximum effort, with OpenAI citing Sol’s cost per task as about 9% of Opus’s.
Factuality / error-rate improvement vs predecessorOn OpenAI's internal factuality evaluation, GPT-6 Sol made about half as many factual mistakes as GPT-5.6 Sol, improving reliability for coding and computer-use tasks.
Rollout scheduleRollout starts globally for Plus, Pro, Business, and Enterprise users; Free and Go users follow one day later.
Availability in ChatGPT Work, Codex, and APIAt launch, GPT‑6 Sol is available in ChatGPT Work and Codex for most paid accounts and is offered via the ChatGPT API; rollout in ChatGPT is gradual.

OpenAI rolls out GPT-6 with Intelligent UI in ChatGPT
GPT-6 is rolling out globally inside ChatGPT and introduces an "Intelligent UI" that delivers faster responses along with visuals and interactive experiences you can explore and use directly.
OpenAI reopens $200 Pro plan but halves API credits per dollar
OpenAI is reopening its $200-per-month Pro subscription to new sign-ups while cutting the amount of API credits granted per dollar by half; the previous 5-hour usage cap for subscribers has been removed. Employee Thibault Sottiaux cited recent releases—GPT-6 Sol and GPT-6 Luna, reportedly released this week at half the API price of predecessors—and framed the changes as a shift toward pay‑per‑use pricing.
