The models share $10 per million input tokens and $50 per million output tokens, but benchmarks split on reasoning, speed and workflow cost.
- Anthropic launched Claude Fable 5.1 on September 1, 2026, followed two days later by OpenAI's GPT-6 Astra on September 3, 2026, initiating a fierce new generation of flagship AI capabilities.
- Both flagship models charge $10 per million input tokens and $50 per million output tokens at the highest pricing tier, yet represent fundamentally different engineering philosophies.
- GPT-6 Astra completes standardized intelligence tasks in 4.0 minutes at $2.57 per task while generating output at 87.5 tokens per second, outpacing Claude Fable 5.1's 9.5 minutes and 68.7 tokens per second.
- Claude Fable 5.1 leads independent intelligence metrics, capturing the #1 position on the Artificial Analysis Intelligence Index with a score of 66, while registering 70 on the Coding Agent Index versus Astra's 67.
- Choosing between these models depends on workload requirements; Astra excels in speed and cost efficiency while Fable provides superior performance for complex knowledge synthesis and academic research tasks.
