A repost claims that OpenAI's GPT 5.6 launch might be their most successful since ChatGPT, suggesting it could be an "IPO-changing" event.
Quoting another analysis, Codex's active users jumped from 5 million to 6 million in 24.5 hours—meaning an increase of about 1 million in a single day. For context, Claude Code's last reported user count was 2 million in February. If accurate, this represents an exceptionally strong recent growth in Codex usage.
