Sourcegraph uses Anthropic's Claude 3 Sonnet as the default model in its AI coding assistant, Cody, which helps developers write and understand code faster. The AI provides context-aware chat and tools like inline code completions, significantly speeding up coding processes. Cody uses different models (Sonnet, Opus, Haiku) optimized for speed, intelligence, and long-context recall, increasing the quality and accuracy of code suggestions. Cody Pro and Enterprise users benefit from even more advanced features powered by these models.
