Model Suguyaw ni Versionw minnu Labɛnnen don Tugun

Tucano ka denmisɛn bɛ taa base model hakɛ naani kan, min bɛ to sɛgɛsɛgɛlikɛlaw ni baarakɛlaw ye model sugandi min ka kan i ka komputɛri seko ni baara laakariw ma:

• Tucano-160m – paramɛtɛri miliyɔn 160

Base modelw minnu kalan sɔrɔ fɔlɔ, olu fara kan, poroze ye derivative labɛnnen caman fana bɔ. Tucano-SFT ani Tucano-DPO ye supervised fine-tuning ani direct preference optimization versionw jira, kelen kelen, wa Tucano-2b4-Instruct ye instruction-following version ye base model min ka bon kosɛbɛ o la.
