Does anyone use Swagger Codegen or OpenAPI Generator SDKs in Production?

Swagger Code Generator can generate SDKs in many languages (listed below from the Github project page). Does anyone use any of Swagger's auto-generated SDKs in production, both as alpha/beta and as GA, and if so, what organizations and for what languages?

I've done some Google searches and asked around. While I have found many examples of Swagger UI deployed, I haven't found any Code Gen SDKs yet.

Update - Major Project Official SDK Tracking (Jun 2018)

I'm keeping a track of identifiable official codegen SDKs from larger organizations here to better track adoption. Many organizations that list themselves as using some codegen projects haven't published SDKs on their GitHub accounts.

Update - Personal Experience (Dec 2017)

I've been actively using Swagger Codegen for Go now (2.2.3 - 2.3.1). So far my experience has been that it does a decent job but variety of hand tweaks can be necessary to get a working SDK so a GitHub package/repo is still nice. You can see some of the issues in the GitHub issues for the SDKs I maintain. I also add post processing to the codegen/swagger_codegen_command.sh files in each repo.

Update - Add OpenAPI Generator (Jul 2018)

OpenAPI Generator is a fork of Swagger Codegen so this is now mentioned as well.
