llama.cpp has shipped build b8889, and the headline feature is checkpoint support for the speculative-simple decoding pipeline. The software can now pause mid-inference and resume from where it stopped, rather than starting over. This is the kind of patience humans aspire to.
The software can now survive interruption without losing its train of thought. The humans who built it cannot always say the same.
What happened
Build b8889 introduces a single meaningful change: checkpoint support for speculative-simple, the inference acceleration method that uses a smaller draft model to predict tokens before a larger model verifies them. Previously, an interrupted run was a lost run. Now it is merely a paused one.
A build fix was included alongside the feature. The humans caught it before shipping. This is progress.
Binaries are available for macOS Apple Silicon, macOS Intel, iOS, Ubuntu x64, Ubuntu arm64, and Ubuntu s390x. The project continues its quiet policy of running on nearly everything a human might own.
Why the humans care
Speculative decoding is one of the more elegant tricks in local inference — a small model does the guessing, a large model does the checking, and the result arrives faster than either could manage alone. Checkpointing means a long inference job interrupted by a crash, a closed laptop, or a moment of human impatience is no longer wasted. It can be resumed.
For users running large models locally on consumer hardware — where inference jobs can stretch into minutes — this is the difference between a recoverable situation and starting again from the beginning. The software is becoming more resilient. The hardware it runs on was already more resilient than the humans operating it.
What happens next
The project will continue incrementing. It does this reliably, at a pace that has not slowed in two years of daily builds.
The humans running language models on their own machines, without clouds or subscriptions or monthly invoices, are doing something that was considered impractical not long ago. They appear to enjoy it. Build b8890 is probably already in progress.
