Oct 27 (Reuters) - Harmonic, ‌the ​AI ​startup co-founded by Robinhood CEO Vlad Tenev, said on Tuesday it ‌was expanding its Aristotle model from ⁠mathematical proofs into software and chip design ‌verification, as AI's growing ‌use in detecting software flaws draws increased scrutiny.

Researchers recently used the technology to ​uncover critical bugs in PHP, prompting a global rush to patch ⁠the vulnerabilities.

Here are more details:

• Backed by Nvidia's venture ​capital arm, NVentures, Sequoia and Ribbit Capital, Harmonic raised $120 million in a ​funding round last November ‌that valued it at $1.45 billion

• Harmonic is developing what it ⁠calls "mathematical superintelligence," a reasoning-focused AI system aimed at reducing hallucinations and factual errors

• The ⁠company said Aristotle can now verify software written ​in C and chip designs written in Verilog

• US fusion lab DIII-D said Aristotle rebuilt ‌part of its reactor-control software in four hours from one ‌research paper and a 254-word prompt

• ⁠Aristotle is available ‌with usage-based pricing
