The radar’s curated relations list them as competitors. **Data note:** 7 of the last 14 days were not collected live. No collection ran on Oct 22–Oct 28, or a later run refilled those days at once. Every hype score is measured against the 14 days before it and those days are thin, so the scores, the stages and the week-over-week theme trends may read higher than they are until they leave that window on Nov 12. ## At a glance | Measure | OpenAI Codex | Cursor | |---|---|---| | Stage | 💤 Quiet | 🚀 Rising | | Hype score | 7.7 | 25.2 | | 7-day change | +3.6 | +20.2 | | In hype since | not in hype now | Oct 29, 2026 | | Peak, 30 days | 27.7 on Sep 30, 2026 | 45.5 on Oct 13, 2026 | | Stories in 7 days | 416 | 167 | | Share of voice, 7 days | 3.1% | 1.5% | | Sources above normal | 0 of 20 | 2 of 18 | | Category | 🤖 Agents | 🤖 Agents | ## Hype score, last 30 days Both hype scores by day, newest first; on the page’s chart, OpenAI Codex is the solid line and Cursor the dashed one. | Day | OpenAI Codex | Cursor | |---|---:|---:| | Oct 29, 2026 | 7.7 | 25.2 | | Oct 28, 2026 | 2 | 8.9 | | Oct 27, 2026 | 2.2 | 0.4 | | Oct 26, 2026 | 1.6 | 0 | | Oct 25, 2026 | 0 | 0 | | Oct 24, 2026 | 0 | 0 | | Oct 23, 2026 | 4.3 | 5 | | Oct 22, 2026 | 4.1 | 5 | | Oct 21, 2026 | 6.4 | 15.6 | | Oct 20, 2026 | 4.1 | 22.2 | | Oct 19, 2026 | 2.6 | 9.3 | | Oct 18, 2026 | 12.6 | 9.6 | | Oct 17, 2026 | 1.5 | 12.3 | | Oct 16, 2026 | 4.5 | 40.6 | | Oct 15, 2026 | 20.5 | 35.8 | | Oct 14, 2026 | 19.6 | 32.6 | | Oct 13, 2026 | 15.8 | 45.5 | | Oct 12, 2026 | 15.3 | 29.5 | | Oct 11, 2026 | 0 | 17.5 | | Oct 10, 2026 | 4.4 | 35.3 | | Oct 9, 2026 | 14.9 | 27.4 | | Oct 8, 2026 | 21.7 | 30.9 | | Oct 7, 2026 | 15.5 | 27.6 | | Oct 6, 2026 | 17 | 28.4 | | Oct 5, 2026 | 3.4 | 25.4 | | Oct 4, 2026 | 0 | 26.6 | | Oct 3, 2026 | 1.9 | 15.2 | | Oct 2, 2026 | 12.2 | 26.6 | | Oct 1, 2026 | 6 | 27.5 | | Sep 30, 2026 | 27.7 | 28.4 | ## Shared themes What the stories of both topics in the last 7 days are about, as classified by the Jev model (a story can carry several themes): - [Agents](https://abovethefog.app/themes/agents.md) — 65% of OpenAI Codex’s stories, 49% of Cursor’s - [Protocols & infra](https://abovethefog.app/themes/protocols_infra.md) — 26% of OpenAI Codex’s stories, 16% of Cursor’s - [Usage & adoption](https://abovethefog.app/themes/usage_adoption.md) — 30% of OpenAI Codex’s stories, 11% of Cursor’s - [Security & safety](https://abovethefog.app/themes/security_safety.md) — 8.9% of OpenAI Codex’s stories, 50% of Cursor’s - [Models](https://abovethefog.app/themes/models.md) — 24% of OpenAI Codex’s stories, 4% of Cursor’s ## OpenAI Codex: stories behind it 1.
