It does leverage various models, but

- github copilot PR reviews are subpar compared to what I've seen from other services: at least for our PRs they tend to be mostly an (expensive) grammar/spell-check

- given that it's github native you'd wish for a good integration with the platform but then when your org is behind a (github) IP whitelist things seem to break often

- network firewall for the agent doesn't seem to work properly

raised tickets for all these but given how well it works when it does, I might as well just migrate to another service
