Top Large Language Models for Coding in 2025

GPT-5 (OpenAI): As of 2025, GPT-5 is a top contender, known for its advanced unsupervised learning capabilities and multimodal functionality. It excels in complex reasoning and conversational dialogue, with its proprietary nature and high performance making it a top choice for large-scale enterprise applications and multi-step tasks.

Gemini 2.5 Pro (Google): Pushing the boundaries with its multi-modal and contextual mastery, Gemini 2.5 Pro is an excellent choice for code generation and full-stack development. Its massive context window (over 1M tokens) and structured reasoning make it invaluable for tasks requiring deep code and media analysis.

Claude 3.7 Sonnet (Anthropic): This model stands out for its exceptional contextual awareness and ability to handle long coding workflows. With a 200K token window, it is ideal for working with large codebases and complex projects, providing natural and reliable code completions in multiple languages.

Llama 4 (Meta): Llama 4 is making waves in the open-source community. The series, particularly Llama 4 Maverick, is praised for its massive context window (up to 10M tokens) and impressive performance on STEM benchmarks, making it a strong, customizable, and free alternative.

DeepSeek V3: A leading open-source model with a focus on reasoning and coding. Its Mixture-of-Experts (MoE) architecture and large context window make it a powerful, efficient, and cost-effective choice for developers who want to self-host or integrate through an API.

StarCoder 2: An open-source model optimized specifically for code generation. Trained on a vast dataset of source code, it consistently outperforms other models of similar size on coding tasks, making it a top choice for developers looking for a specialized and powerful tool.

GitHub Copilot (OpenAI): While not a standalone LLM, Copilot is the most well-known AI coding assistant. It's powered by an advanced OpenAI model and offers seamless, real-time code suggestions and completions directly within popular IDEs, significantly boosting developer productivity.
