LG AI Research opens its K-EXAONE 2.5 model to all developers through a free API
Published:
LG AI Research said on 9 November that the API for K-EXAONE 2.5, its proprietary foundation model, is available free of charge through its EXAONE API Platform. Developers, start-ups, companies and research institutions can use it for service development and research by obtaining an API key, the lab said.
LG describes K-EXAONE 2.5 as a technical validation model with additional training on top of the version it released in August. Digital Today reported that the announcement was made at Nvidia AI Day Seoul 2026 and that LG wants to test the model's performance and usability in real services.
LG claims, from internal evaluations on public datasets, scores of 59.2 on SWE-Bench Pro, 78.0 on BrowseComp, 74.6 on AutomationBench-Openset and 77.3 on Claw-Eval, and says the model is competitive with DeepSeek-V4.1-Flash and GLM-5.3 on agentic tasks. It pitches the model for code generation, debugging, refactoring and test writing.
Caveat. All benchmark figures are LG's own claims from internal runs and have not been independently reproduced. LG did not say how long the API will stay free or what rate limits apply, and it did not announce open weights for version 2.5.
