Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
LG AI Research released the K-Exaone 2.5 API for free on April 9, announced at Nvidia's AI Day Seoul 2026 at COEX, letting developers, startups, enterprises and research institutions obtain an API key to call the model. The release is a technology-validation version built by applying additional training to the model unveiled in August; lab head Kim I-reun said internal analysis across 24 evaluation metrics showed performance improved by more than 70% versus the August model. The figures are LG's own benchmarks, with independent verification and OpenShell security performance still pending. The move matters as a free-access bid to widen adoption of Korea's flagship foundation model among developers and enterprises. What to watch next is third-party benchmark results and how the free API translates into usage and ecosystem uptake.
