Overview

The AI development race is accelerating with three major model developments happening simultaneously. OpenAI confirmed GPT 5.3 is in development, DeepSeek dropped hints about a new model through code repository updates, and Google’s Gemini 3.5 leaked through AB testing - though early testing shows disappointing performance compared to current models.

Key Takeaways

  • Version numbers reveal development philosophy - GPT 5.3 suggests incremental refinements rather than revolutionary breakthroughs, helping set realistic expectations for AI progress
  • Code repository changes can signal major developments - DeepSeek’s infrastructure updates for efficient inference suggest they’re building something significant while maintaining their focus on cost-effectiveness
  • AB test leaks provide early insights but can be misleading - leaked checkpoints show work-in-progress models that may not represent final performance, so early benchmark results should be interpreted cautiously
  • The AI race is now global and simultaneous - multiple companies are pushing updates at the same time, indicating increased competitive pressure beyond just US-based labs
  • Focus on real-world utility over hype - look for beta testing results and actual new capabilities rather than getting caught up in version number announcements or marketing claims
