GPT-6 Astra vs Claude Fable 5.1: Which AI Is Actually Better?

GPT-6 Astra and Claude Fable 5.1 arrived almost at the same time, but they are stronger in very different areas. In this video, I compare what we currently know about both models, including independent testing, coding agents, reasoning, tool use, context handling, pricing, architecture reports, cybersecurity, efficiency, and early real-world results. Fable 5.1 looks stronger for sustained reasoning and long complex tasks, while Astra appears heavily optimized for agents, tools, computer interaction, and getting work done. I also explain the important caveats behind Astra’s ARC-AGI results, the reported recurrent-depth architecture, and why comparing Claude Code with Codex tells us more than raw benchmark numbers alone. #GPT6 #GPT6Astra #Claude #Fable51 #OpenAI #Anthropic #AI #AIAgents #ClaudeCode #Codex #LLM #ArtificialIntelligence
