bonsai2-27b

bonsai2-27b is a skill for Claude Code from Aitherium/awdk. It costs 109 tokens per session (2,532 once invoked), scanned C, original, no licence file.

A way to run PrismML's Bonsai 2 27-billion-parameter language model as an OpenAI-compatible local service. It uses a specialised PrismML version of llama.cpp rather than the standard version.

In plain words
What is it for?
Use it to install, serve, and troubleshoot Bonsai 2 locally.
Why use it?
It lets you self-host this model on a GPU or CPU machine and explains problems such as gibberish output caused by using the wrong server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

bonsai2-27b scanned grade C with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -s http://127.0.0.1:8080/v1/chat/completions -H 'Content-Type: application/json' -d '{

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo apt-get update && sudo apt-get install -y build-essential cmake libcurl4-openssl-dev git

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bonsai2-27b is a skill published in the GitHub repository Aitherium/awdk (11 stars, last pushed yesterday), with no licence file. It adds 109 tokens to every session and 2,532 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it C with 3 findings (sends data to an external url, asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
