Hi HN, I'm Mohan from Antigma Labs. Ante is a coding agent that ships as one self-contained ~15MB binary: the TUI, an embedded ripgrep, local PDF/OCR, and a natively managed llama.cpp engine are all inside. No runtime dependencies, no node_modules, no account.

- Ante installs a pinned, checksum-verified official llama.cpp build matched to your machine (Metal on Apple silicon; CUDA, Vulkan, or CPU on Linux) and handles upgrades when the pin changes. - It discovers GGUF files already on disk (~/.ante/models, the llama.cpp and Hugging Face caches), attaches to llama servers already running on local ports, and estimates RAM/VRAM from model size and context window before anything loads. - `ante --offline-model /path/to/model.gguf "prompt"` boots the server, runs the session, and shuts it down. `/offline-mode` does the same interactively; `ante serve --offline-model` loads a model once for many clients. - No API key, no account. Once the model is on disk, inference needs no network at all; set ANTE_TELEMETRY=off and no telemetry is exported either.

On capability, we'd rather publish the number than oversell: we benchmark local models with the same harness and auditable runs as frontier ones, and Qwen3.6 27B (a 17 GB download) scores 56.2% on Terminal-Bench 2.1 across 445 trials (live results: https://antigma.ai/eval). That's a real gap from frontier models. The design bet is that you mix: hosted providers and local live in the same catalog, `/providers` switches mid-session, so sensitive repos or high-volume work go local and hard problems go frontier.

Hosted models work with your own keys or subscription. But nothing about trying Ante requires signing up for anything: download the binary, point it at a GGUF.

Offline mode is under active development and has rough edges with the overview at https://ante.run/local/overview. I'll be in the comments.

Not sure why this was dead but I vouched. It would be nice if telemetry was opt-in, otherwise this looks awesome and can't wait to try it!
ubermon•13m ago
will add those soon!
majorchord•57m ago
Opt-out telemetry is a hard no for me, sorry.
stronglikedan•48m ago
Right? How hard is it to just ask a single opt-in question during installation. Opt-out just seems lazy, especially if I have to dig though configs to get to it.
nextblock•14m ago
Agreed! When a tool is explicitely marketed for offline use, opt-out telemetry feels especially contradictory. Should Definitely be opt-in by default...
niutech•37m ago
Why not make it Actually Portable Executable using Cosmopolitan Libc, like Llamafile, to make it run on Windows/Linux/MacOS? Why don't you support Windows with CUDA?

How good is it to work on building games, compared to existing agents? I am building my own game?
ubermon•1h ago
we have a detailed launch thread explaining and show case exactly this! https://x.com/NoCommas/status/2086835536598351955

You aren't building your own game if you have a chatbot do it for you.
stronglikedan•51m ago
That's like saying you aren't building a house if you use a hammer to drive nails instead of your hand. AI is just a tool like any other, and you use it to build things like you would any other tool.

> That's like saying you aren't building a house if you use a hammer to drive nails instead of your hand. AI is just a tool like any other, and you use it to build things like you would any other tool.

A coding agent is more like a carpenter, a mason, an electrician,... rather than a hammer in that case.

bigfishrunning•43m ago
I'd say it's closer to a Roomba then a hammer -- if you just let a Roomba run around your living room, can you say you vacuumed?
NitpickLawyer•41m ago
Linking to a github repo for a binary release (no source code related to the agent that I could see) is a bit iffy IMO. You should clarify your intentions or link to something else. Might confuse folks.
adastra22•26m ago
Linking to a binary is iffy from a security perspective. Linking to a GitHub repository is exactly what HN should do.
OleksandrC•21m ago
I will leave this here: https://usehax.dev/ GitHub repo: https://github.com/OleksandrChekhovskyi/hax

This is a coding agent implementation I am working on, which delivers what this promises (at least on the "lean" part), except it's actually fully open source, and even more lean (few MBs of runtime memory usage).

MIT-licensed, written in C, multi-provider / multi-model, minimalist approach to system prompt and tools (think kinda like pi, but with a bit more "batteries included", like subagents and background tasks out of the box), polished presentation, inspectable (usable transcript view), etc.

ubermon•10m ago
nice, good to see more contributor in this space
ubermon•10m ago
we put it in the repo README, will add migrate more into public repo as soon as possible.
_pdp_•40m ago
Considering that ripgrep, git, and, you know, other dev tools are part of the toolbox, then why ship them inside this executable? And, furthermore, if you ship them, then why stop there?
ubermon•6m ago
so it is more for being self contained and works out of box if being deployed in a bare linux environment. we tried shell out to `rg` it didn't work very well and instead spending time handling the args parsing and jugging string output, we decided to spend time on building Grep natively for agent. It is just a start~

as for why stop here yep, the goal is to be able to find the best sweet spot in being self contained v.s. all-in-one bloat ware. for example, we still use a bundled `tmux` skill for the orchestration.

jhgik798•38m ago
no source code
ubermon•11m ago
partially, we indent to progressively add source code component to it. the crates/ is sync from the active repo in realtime.
plainviewinstru•18m ago
this would go very hard with a lightweight gui
ubermon•12m ago
yes, the goal is to perfect the `ante serve` so it is easy to build gui. We are building one internally to test the protocol version
23m ago
Where is the source code?
ubermon•5m ago
for now only some of core crates is migrated, will do so progressively
simlevesque•23m ago
Well, you tell your Roomba "clean the floor" but you don't ask an AI "make a game". You give it very specific instructions.
finghin•18m ago
Specific compared to writing procedural code> Barely even by analogy, IMO

One could even argue what defines AI instructability is heuristics as opposed to specifics

schnevets•30m ago
I wouldn't even compare it to a tool. People frequently "build their own house" where they sub out 75% of the skilled labor and act as a General Contractor/glorified gopher.

And you won't get purity tests from the layperson: in the end, you're responsible for the build quality so if you tirelessly labor/oversee those teams you're considered capable; if it ends sub-par, then you're a stooge.

ThrowawayR2•23m ago
A far more accurate analogy would be people saying someone didn't write a book if they hired a ghostwriter, which is generally acknowledged to be true. LLMs are much closer to being a ghostwriter than they are to an inert, non-powered hand tool.
perching_aix•44m ago
Same idea that sends people down needless game engine development / procrastination rabbit holes.

This is such a horrible cringe and bad faith take.

A classic tale from the music production world comes to mind:

"I thought using loops was cheating, so I programmed my own using samples. I then thought using samples was cheating, so I recorded real drums. I then thought that programming it was cheating, so I learned to play drums for real. I then thought using bought drums was cheating, so I learned to make my own. I then thought using premade skins was cheating, so I killed a goat and skinned it. I then thought that that was cheating too, so I grew my own goat from a baby goat. I also think that is cheating, but I’m not sure where to go from here. I haven’t made any music lately, what with the goat farming and all."
