Cons
- -Unofficial library requiring developers to stay updated on breaking changes from OpenAI's official API
- -Requires Go 1.18 or higher, potentially limiting use in legacy Go environments
- -API key management and security considerations are left to the developer
- -Currently limited to Completion endpoint only, lacking support for newer OpenAI features like Chat completions
- -Relatively small community with 371 GitHub stars compared to official SDKs
- -May lag behind latest provider API updates due to abstraction layer maintenance overhead
