OpenAI announced ChatGPT Work on July 9, providing two versions. Work Cloud is available through chatgpt.com and mobile apps and requires a $20 per month subscription. Work Local is part of the desktop application formerly known as Codex and also requires a paid subscription. The service offers model selection among GPT-5.6 Sol, Luna, and Terra with reasoning levels from Light to Ultra. Users can run code in an environment with internet access, including cloning repositories and installing dependencies. A headless Chrome browser can load pages, fill forms, execute JavaScript, and take screenshots. Each session maintains a persistent workspace folder that is shared across sessions. Work can publish ChatGPT Sites using Cloudflare Workers, with options for private or shared access. Sub-agent functionality allows multiple agents to operate simultaneously. Scheduled prompt automations can run recurring tasks. OpenAI has not disclosed the system prompts or detailed tool descriptions, and users have raised concerns about prompt injection and data security.
