Q Developer Pro subscription limits?

Amazon Q Developer Pro tier does have some usage limits, although they are not as restrictive as the Free tier. For the Pro tier, there are specific quotas for certain features, but general interactions do not have hard monthly limits.

For Amazon Q Developer Agent for software development in IDEs and Amazon CodeCatalyst, there is a quota of 30 invocations per month. Pull request summaries in Amazon CodeCatalyst are limited to 20 per month.

The error message you're encountering suggests that you've reached a maximum limit for a specific type of interaction (GenerateAssistantResponse). This limit is likely an internal quota that is not publicly listed.

Unfortunately, there isn't a straightforward way for users to increase these internal quotas themselves. The quotas are designed to ensure fair usage and optimal performance for all subscribers.

Adding a second developer user may not solve the issue if it's an account-level limit rather than a user-level limit, as you've correctly surmised.

While the Pro tier offers higher usage limits compared to the Free tier, it appears that there are still some restrictions in place. If you're consistently hitting these limits and require increased usage, you might need to contact AWS support or your account representative to discuss your specific needs.

Without a paid support plan, your options for immediate resolution are limited. You could consider upgrading your support plan if the increased productivity justifies the cost. Alternatively, you might want to explore if there are any inefficiencies in your current usage that could be optimized to stay within the existing limits.

AWS is likely to be receptive to feedback about increasing limits for power users, so you might want to provide this feedback through available channels, even if you can't get an immediate resolution.

Clearly this has changed at some point.

I do not use java transformations or anything that has documented limits. But suddenly on the 13th of this month I receive this message from q chat:

Monthly request limit reached - The limits reset on 11/01.

That's almost 3 weeks where this service will be unavailable for me. I find it hard to justify a service I can only use for a little over a week each month. There is no clearly documented way to obtain - even pay for - additional quota.
