LG AI Research has launched free API access to its K-EXAONE 2.5 model, a 750-billion-parameter AI system optimized for coding, search, and automation tasks, available via the EXAONE API Platform for developers and researchers.

What happened

On November 9, 2026, LG AI Research began offering free API access to its K-EXAONE 2.5 model through the EXAONE API Platform. This model has 750 billion parameters and is designed for tasks such as coding, search, and automation. Developers, startups, companies, and research institutions can now obtain an API key to use the model for service development and research. The model supports both Korean and English and is available as a hosted service.

Key details

  • K-EXAONE 2.5 has 750 billion parameters, with 31 billion active at runtime.
  • The model supports a maximum context length of 524,288 tokens per request.
  • It is text-only and supports Korean and English languages.
  • API access is free and uses an OpenAI-compatible interface.
  • The model was last trained with knowledge up to January 2026.

Why it matters

Developers, companies, and research organizations now have free access to a large-scale AI model for building and testing software tools, search systems, and automation solutions. This reduces the financial barrier for experimenting with advanced AI in coding and workplace automation. The OpenAI-compatible API allows integration into existing workflows, enabling faster evaluation and adoption of LG's technology in real-world applications.
