What is the grade of the hadiths in al-Tabarani's "al-Jami' al-Kabir"?

Question:
It is well known in the books of hadith that al-Tabarani, in "al-Kabir," collected more than the people of the six authentic collections (al-Sahih al-Sittah) strived to collect. Does what al-Tabarani included in "al-Awsat" and "al-Kabir" reach the status of the books of the six Imams, or does the student of knowledge need to be cautious and investigate this? And what do you advise the student of knowledge? May Allah reward you with good.

Answer:
Yes, caution is needed; because al-Tabarani, in his three collections, gathers the weak, the authentic, and the fabricated. Therefore, attention must be paid to the chains of narration. Likewise, for everything other than "the two Sahihs," attention must be paid to the chains of narration: such as the four Sunan, al-Bayhaqi, al-Darimi, al-Hakim, Ibn Hibban, and others. Attention must be paid to the chains of narration. Likewise, al-Daraqutni and others. All these books require attention from the scholars. So, what is authentic must be adopted, and what is weak, if it has corroborating narrations that support it and improve it, is adopted; otherwise, it is left. These books are not to be taken with their defects without examination or distinction. No, distinction is necessary.
Al-Tabarani is one of those who collected extensively, may Allah have mercy on him, but he gathers the worthless and the valuable, the weak and the authentic. Therefore, attention and distinction are necessary between the good and the bad in terms of the chains of narration, the reliability of the narrators, the continuity of the chains and their lack of disconnection, and other than this from the known defects among the scholars.
