Línea de trabajo

Comienza en camel/model_backend.py, donde se llama a tiktoken.encoding_for_model, y reproduce el comando indicado con GLM_4 y la BASE_URL proporcionada. Rastrea cómo se seleccionan los nombres de los modelos y las codificaciones de tokens. Se considera completado cuando GLM-4 puede invocarse mediante este comando sin el KeyError del tokenizador indicado.

Escrito por el modelo de indexación a partir del texto del issue.

Once we all have expressed our opinion(s) and agree with the results of the discussion unanimously, any of us must actively terminate the discussion by replying with only one line, which starts with a single word , followed by our final product modality without any other words, e.g., " PowerPoint".
