Few points stand out, and the online criticism of this announcement appears excessive.
New limits apply to recent users. Longstanding subscribers retain x20 usage above the Plus plan.
Unlimited 5.6 Sol is a new feature in this $200 plan. Newer models demand more compute; a 2.5T parameter model would need more than a 2T model. Better models naturally provide less usage because the unit price is much higher.
O Bots, when activated in this plan, add $50–$100 in fixed cost. Muse and Grok bots already carry this cost. These Linux sandboxes extend the existing subscription.
Consider the perspective of a company at times; expecting more is not a fair or sustainable request.
