The major companies developing AI tools provide a variety of models under their service umbrellas. New models and updates are released frequently, so continued monitoring of developments in this area is prudent.
This well-rounded model from OpenAI is state-of-the-art for most tasks and queries. Good at coding, reasoning, lookups, research, and summarizing—almost anything you throw at it.
Claude Sonnet from Anthropic is very good with general support. It lags slightly behind ChatGPT 5 in debugging tasks and technical understanding of complex contexts, but the Claude app is also very convenient and works well from the desktop
One of the best models for debugging and vibe coding via the Canvas mode, Gemini Pro 2.5 from Google has the ability to handle up to 1 million tokens, making it ideal for large, complex projects. It can be especially useful in research services applications with extensive coding tasks. It is a good all-rounder too..
Grok from xAI is especially fast and has a very generous free usage allocation. It handles many technical problems, such as configuration issues, better than many other models. The research mode is very useful, and another great feature is its customizability to respond with concise and exact answers, if that is the user’s preference. The other models listed here are better at general coding tasks, though.
GitHub Copilot from Microsoft defaults to a ChatGPT plugin, but other models can be selected, such as Claude or Gemini. A recent update also allows integration with open-source AI tools. Subscriptions are recommended for agentic tasks.
