llamafile (by Mozilla) distributes large language models as single executable files that run on any computer without installation, dependencies, or configuration.

The technology combines the Llama.cpp inference engine with Cosmopolitan Libc to create truly portable executables that work across Windows, macOS, Linux, FreeBSD, and other operating systems without modification. This eliminates every friction point in running local AI: no Python, no Docker, no package managers, no GPU drivers (though GPU acceleration is supported if available). Performance is competitive with dedicated inference solutions. Available models include Llama, Mistral, Phi, Rocket, and others distributed as llamafile executables. The project is completely open source and free. llamafile is ideal for air-gapped environments, security-sensitive use cases, demonstrations, and anyone who wants the simplest possible path to running AI locally.

What is Perplexity AI?
Perplexity AI reimagines search as a conversation.

This makes it the most trustworthy AI assistant for research, fact-checking, and staying informed on current events. The free tier supports unlimited basic searches. Perplexity Pro ($20/mo) unlocks Pro Search with Claude, GPT-4, and other advanced models, plus file upload analysis and API access. Focus modes narrow searches to academic papers, YouTube videos, Reddit discussions, or writing assistance. Collections allow organizing research into shareable projects. Perplexity is particularly valuable for journalists verifying claims, researchers surveying literature, students writing papers, and professionals who need sourced answers rather than AI-generated opinions.
