Episode notes
Workflow Coherence Beats Raw Copy Skill
- GPT 5.4 can outperform other models on end-to-end workflows even if it's not the best pure copywriter.
- Gael found 5.4 handled hooks, technical processing and multi-step tasks more coherently than some rivals.
HTML Slides Plus Screenshots Solved Carousel Jank
- Gael built a LinkedIn carousel skill using HTML slides and screenshots to avoid image-model layout shifts.
- He reports GPT 5.4 produced more consistent, higher-quality executions than Opus 4.6 for this workflow.
Native Computer Use Makes Agents Practical
- Native computer use means models actually perform actions (browser, files) instead of just returning text outputs.
- Gael says this reduces layers, saves tokens, and makes agentic workflows faster and more reliable.
