Vinami is a figure that appears in Jain texts in connection with the era of Rishabhanatha and with the lineage of Vidyadevis. There are a couple of traditional attributions, which differ between sources:

• In Harivamsha (Harivaṃśapurāṇa), Vinami is mentioned as one of the youths (along with Nami) who troubled Lord Rishabhanatha for worldly wealth; Dharanendra later grants them spiritual gifts, linking Vinami to the episode of wealth and devotion. This account emphasizes their initial attachment to wealth and their later reception of divine knowledge. ( jaingpt.org)

• In Hemacandra’s Triṣaṣṭiśalākāpuruṣacaritra (Adīśvara-caritra, 1.3), Vinami is described in a different frame as the son of a king (often given as Mahākaccha in some recensions) who, along with Nami, receives and uses special siddha-vidyās under the patronage of Dharanendra. This places Vinami in a more mytho-historical context within the biographical literature of the Jinas. ( wisdomlib.org)

• Both Digambara and Śvetāmbara traditions later list Vidyādevi (Knowledge-Deities) associations around Vinami in different ways, and over time the tradition broadened such lists into guardian-deity lineages. This is part of a broader discussion about Shasan Devta (guardian deities) and Vidyadevi origins in later Jain literature, where Vinami appears among related figures in some enumerations. The exact names and roles can vary between traditions. ( jaingpt.org)

In short, Vinami is not a standalone, contemporary historical figure; he is a legendary figure associated with the era of Rishabhanatha and with the transmission of spiritual knowledge in later Jain narratives. The two main traditional strands place him in somewhat different roles, and the list of associated deities varies between Digambara and Śvetāmbara traditions.
