What is Prompt Octopus?
Prompt Octopus is a powerful tool designed for side-by-side prompt engineering, enabling users to compare responses from over 40 AI models like OpenAI, Anthropic, DeepSeek, Mistral, and Grok directly within their workflow. It allows highlighting prompts in codebases, selecting multiple models, and evaluating outputs side by side to identify the best model for specific tasks. Primarily aimed at software engineers, AI developers, and teams at companies like Microsoft, it integrates seamlessly into development environments such as VSCode.
Key features include running evals directly in your codebase, saving prompt and model preferences for reuse, and comparing responses in real-time to optimize prompt performance. Users can bring their own API keys for unlimited free usage, with options to try the first 10 comparisons without any setup. The VSCode extension makes it effortless to install and use within IDEs, streamlining the process of model selection and prompt refinement.
This tool is ideal for engineers building AI applications who need to rigorously test and compare LLM outputs without switching contexts. It supports dozens of models, ensuring broad compatibility, and emphasizes privacy by storing API keys locally. Whether prototyping, debugging prompts, or scaling evals, Prompt Octopus accelerates the path to optimal AI performance.
