Tempo9 runs on Apple Silicon Macs (M1 or later), macOS 13+.
Release status
Not published yet. The Homebrew tap and the signed, notarized binaries are the last work before the first public build. Until then, the manual, writing, and measurements are available.
Install after release
brew install thinkspread/tap/tempo9
Run
tempo9 --gguf ~/models/your-model.gguf --port 11435
Then point an existing client at it:
# OpenAI-compatible base_url = http://127.0.0.1:11435/v1
# Anthropic-compatible base_url = http://127.0.0.1:11435
Tempo9 has been tested with Codex, Claude Code, OpenClaw, and other local agent platforms that let you set an OpenAI or Anthropic base URL.
Port 11435 sits next to Ollama's 11434, so both can run side by side.
What you actually install
One binary and its Metal shaders. Every dynamic library Tempo9 links is already on macOS — no Python, no runtime, no framework, and nothing from Homebrew.
| Download | Non-system libraries | |
|---|---|---|
| Tempo9 | 9.9 MB | 0 |
| llama.cpp b10307 | 42 MB | 10 |
Measured on the same machine with du and
otool -L. llama.cpp's llama-server is a 49 KB shim
over eight sibling dylibs in its build directory, and it also links Homebrew's
openssl@3 — so it needs Homebrew installed and breaks if that
formula moves. Ollama 0.32.15 installs 80 MB, though it bundles model
management that Tempo9 does not have. The point is not the megabytes: it is
that the file is the program, so there is nothing else to keep in sync
with it.
Models
Tempo9 loads GGUF files directly. On first use it builds and caches an
execution graph under ~/.cache/tempo9/; later runs reuse it.
SDK
Building a Mac app? The Swift package is open source (Apache-2.0) and wraps the engine as a binary dependency.
.package(url: "https://github.com/thinkspread/tempo9", from: "1.0.0")
import Tempo9
License
The engine is proprietary, free for individuals and small businesses: free to use if you are an individual, or a company with fewer than 100 employees and under $1M in annual revenue. Above that, a commercial license is required.
The Swift SDK and the server CLI are open source under Apache-2.0.
Exact terms are being finalised. If you want to use Tempo9 commercially before then, email me.
