Episode notes
Compare Models Side By Side Before Choosing
- Try comparing multiple top models before committing; Jaeden recommends using AIbox.ai to test models side-by-side for $8.99/month.
- He highlights access to 40+ models (Grok, Gemini, Anthropic, OpenAI) and automated workflows as practical evaluation tools.
Model Variants Built For Professional Workflows
- GPT 5.4 Thinking and GPT 5.4 Pro target professional workflows with bigger context windows for long documents and codebases.
- The API supports up to a one million token context, enabling analysis of huge conversations, codebases, and datasets for complex work.
Better Token Efficiency Cuts Costs And Speeds Responses
- GPT 5.4 improves token efficiency and speed compared to GPT 5.2, which lowers cost and latency for deployed systems.
- Jaeden notes the model solves similar problems using fewer tokens and runs faster, making existing 5.2 integrations cheaper to operate.
