I appreciate how Anthropic keeps the Pro tier priced around OpenAI's Plus tier. The extra tier with OpenAI invites additional product subscription gates. Functionally, Anthropic will have a frontier model driving a personal agent available a 1/5 the cost of OpenAI. Astra may be a bigger model, but is there a meaningful qualitative difference between a personal agent running Opus 5.5 vs GPT6 Astra?
