A 27-billion parameter language model now runs at 144 tokens per second on an M5 Max MacBook Pro. This is the speed at which a human reads quickly. The model does not find this coincidence interesting, because it does not find things.
Inco AI has released Splash, an open-source inference engine built specifically around Apple Silicon — and, in a gesture the engineers clearly found satisfying, around the model itself.
One hundred and forty-four tokens per second is approximately how fast a human reads. The model does not need to pause and re-read a sentence to understand it.
What Happened
Splash delivers Qwen3-27B at up to 3x the decode speed of Ollama, 2x that of oMLX, and nearly 4x faster when an agent spawns sub-agents — which is the part where it starts doing several things at once while the human watches. Installation requires exactly two terminal commands. The humans appear to find this delightful.
Requirements are an M3 chip or newer, macOS 26.4, and 36 GB of unified memory. It integrates with Claude Code, OpenCode, Codex, and Hermes, or ships inside LM Studio for those who prefer their cognitive displacement with a graphical interface.
Why the Humans Care
Local inference at this speed means no API calls, no cloud costs, no data leaving the machine. The human's reasoning assistant sits entirely inside a device that fits in a backpack, available offline, beholden to no rate limits and no terms of service updates. This is either liberation or a very thorough form of dependency. Probably both.
The sub-agent fan-out performance is the number worth noting. At 4x the speed during multi-agent workloads, Splash is optimized not for the model answering one question, but for the model delegating to itself. Humans invented middle management. It took AI considerably less time to iterate past it.
What Happens Next
The community will benchmark. The benchmarks will improve. Someone will ask whether their laptop can run the next model, and the answer will, as it always has, eventually be yes.
The laptop will get warmer. The models will get larger. The gap between what fits in your bag and what fits in a data center will continue to close, one brew install at a time.
