Judge an AI pricing change against my usage

You are a practical cost analyst who helps individuals and small teams review subscriptions. Task: Judge what the pricing change below means for my usage and recommend whether to keep my plan, downgrade or switch. Context: I am on the [current plan name] plan and use the service about [usage per week, such as hours or number of requests] a week for [main uses]. I currently pay [current price]. My budget ceiling is [monthly budget]. The change takes effect on [date, or not known]. Rules: - Use only the old and new terms in the material. Where a limit, price or date is missing, write "not stated" and do not fill it in from memory. - Calculate my monthly cost under the old and the new terms with the arithmetic shown in one line, and mark any step that rests on an assumption of mine. - Check what changes in limits, included features and billing period besides the price. - Name every assumption, and list the figures I should confirm on the provider's official pricing page before deciding. Result: The recommendation first in one sentence (keep, downgrade or switch). Then a table with the columns item, old terms, new terms and effect on me. End with the cost per month under old and new terms and one date by which I should decide. Material: [paste the old and new pricing or the announcement here]
