Research direction

Start with the OpenAI model component's go.mod and inspect the sonic requirement, then reproduce the clean-install build on go1.26.7 windows/amd64. Confirm that the dependency floor resolves the reported GoMapIterator failure and that NewChatModel plus Generate still works against an OpenAI-compatible endpoint.

Written by the indexing model from the issue text.

Description

A clean install of the OpenAI model component fails to build on go1.26.7 windows/amd64:

$ go mod init example && go get github.com/cloudwego/eino-ext/components/model/openai
$ go build ./...
# github.com/bytedance/sonic/internal/rt
…/sonic@v1.14.1/internal/rt/stubs.go:33:22: undefined: GoMapIterator
…/sonic@v1.14.1/internal/rt/stubs.go:36:54: undefined: GoMapIterator

go get resolves github.com/bytedance/sonic v1.14.1, and GoMapIterator is a runtime-internal symbol that is no longer available to it on Go 1.26. Nothing in Eino's own code is involved.

Workaround

go get github.com/bytedance/sonic@latest   # v1.14.1 → v1.15.4

After that the build succeeds and the component works — I ran a NewChatModel + Generate against an OpenAI-compatible endpoint with no further changes.

Why it might be worth a version floor

The compiler error names sonic, not Eino, so someone whose first contact with the project is go get …/components/model/openai on a current toolchain hits a wall that reads as unrelated to what they just installed. Bumping the minimum sonic version in go.mod would turn a confusing build failure into a resolved dependency.

Happy to open a PR for the go.mod bump if that is useful — I have not sent one because I do not know whether a newer sonic breaks anything else you support.
