AI埋め込みバックフィルレーキが中止されました

[Don]

こんにちは

Discourse AI - OpenAI API の使用を開始しました。まず、関連トピック (text-embedding-ada-002) に設定しました。バックフィル用の rake タスクを実行しようとすると、次のエラーが発生しました。

....rake aborted!

また、/logs で以下のものも確認しました。

よろしくお願いします

nil のレスポンスを受け取っているようですね。

ai embeddings enabled をチェックして、設定に API キーを追加しましたか？

[Don]

はい、設定は以下のようになっています。

Jobs::EmbeddingsBackfill は実行されているようですが、OP で言及したエラーで常に失敗しています。

OpenAI に関連しているようです。

[Don]

問題はレート制限だったと思います。OpenAIのティアをアップグレードする必要があり、モデルをtext-embedding-3-largeに変更しました。これで、rake中にたくさんのドットが表示されるようになり、良い兆候です。 完了したらこの投稿を更新します。

編集1：10時間ドット表示の後、rakeが中断しました

rakeを再起動しました。この場合、未処理のトピックのみが処理されるのでしょうか、それともすべてのトピックが再度処理されるのでしょうか？

編集2：rakeは同じエラーで再び中断しました。しかし、これらのプロセスでほとんどのトピックがカバーされたと思います。そして、SidekiqのJobs::EmbeddingsBackfillは正常に実行されているようです。したがって、残りのトピックにはこれで十分だと思います
