llama.cpp and ggml hit v1.0.0, ending the 0.x era after 3.5 years

llama.cpp author Georgi Gerganov announced that the project, along with its underlying library ggml, has released its first official major version, v1.0.0, roughly 3.5 years after the project began. This marks the de facto standard for local/on-device LLM inference leaving the 0.x era behind and entering a stage where API stability can be publicly guaranteed.

Confirmed

• The release covers libllama v1.0.0 (the C/C++ LLM inference library) and libggml, both finalized in sync
• The project commits to semantic versioning: breaking API changes will be signaled by major version bumps
• ggerganov submitted PR #32190 to the repo bumping the version to 1.0.0
• The team (as relayed by Merve Enoyann) pledged to keep covering "every platform, every model" while keeping llama.cpp lean and robust for the thousands of downstream apps and developers that build on it
• Hugging Face simultaneously launched a llama.cpp-based desktop app for local AI (@pcuenq, @unofficialmerve)
• Gerganov called this release a solid foundation for the future of local AI

Why it matters

• llama.cpp is a foundational project for the local/on-device LLM inference ecosystem, supporting vast numbers of downstream applications and millions of developers; the 1.0 release means its API stability has reached a guaranteed level
• The semantic versioning commitment lowers upgrade and maintenance costs for downstream apps
• In the discussion, Julien Chaumond emphasized that AI should not be controlled by a few companies, underscoring the project's strategic role in open-source local inference
