GPT-6 Astra 完成同一任务约用 21K token，Fable 5.1 约 64K
帖子认为 Astra 对 Anthropic 的真正威胁不是跑分而是 token 效率，这也能解释 Claude Code 额度为何消耗快。
OpenAI could be creating a serious problem for Anthropic. And it might have less to do with benchmarks than people think. The real advantage could be efficiency. GPT-6 Astra reportedly uses around 21K tokens to complete a task, while Fable 5.1 can use roughly 64K. That’s a massive difference. If both can get to a similar result, Astra is doing it with far fewer tokens. And that could explain why some tasks that take hours with Fable can be completed much faster with Astra. Even the Claude Code limits start to make more sense. Maybe you’re not actually using Claude too much. Maybe Fable is just burning through tokens much faster. If Astra can consistently deliver similar results while using a fraction of the tokens, that’s more than a benchmark win. It’s a major cost and efficiency advantage. And that’s something Anthropic can’t afford to ignore.
