whisper.cpp

Open source · OSI-approvedStatus: unknown

Speech recognition that runs anywhere, with no runtime

whisper.cpp is a C and C++ port of the Whisper speech recognition model with no Python dependency, quantised weights, and hardware acceleration across Apple Silicon, CUDA, and plain CPU.

It is the transcription engine embedded inside a large amount of other software, precisely because it drops into a project as a library rather than a service.

Decisive facts

  • No Python runtime at inference time
  • Quantised models that run on modest hardware
  • Metal, CUDA, OpenVINO, and CPU backends
  • Streaming transcription with word level timestamps
  • Bindings for most common languages

OpenCode is a coding agent that runs where you already work rather than in a separate chat window. The same session can be driven from a terminal, an editor extension, or a desktop client, and it keeps context across all three.

Excalidraw's sketchy rendering is not decoration. Diagrams that look provisional invite comment, where a crisp vector diagram signals a decision already made, so it is unusually good at the early part of a design conversation.
