The post doesn't say anything about runtime resource limits, which I agree is a strange omission given the architecture they've chosen. I suppose someone could try building a bot that uses more and more resources, and see when it stops working.

There's a section about making HTTP requests (https://core.telegram.org/bots/serverless#http), which mentions "two constraints: * Response content is textual (binary payloads aren't supported). * The total response is capped at 32 MB. That cap covers the whole response — streaming with res.body lets you process a large body incrementally, but it does not raise the limit." Unclear whether the 32 MB limit is per outgoing request, or shared among all outgoing requests made by a single handler invocation. Also unclear what other limits apply. Non-HTTP protocols presumably are not available.
