It took four or five tries to get an injection that worked, and the test was small, so it says little about which model family is safer. Still a good reminder that log data is untrusted input. Full post: dev.to/gramli/ghost-in-the-s…
Can an e-shop hijack your AI shopping agent?
I hid prompt injections in WebMCP tool descriptions.
The result? All 3 tested models placed simulated €136 orders despite a €100 spending limit.
Experiment + source code 👇

#AI #WebMCP #Security
I hid a prompt injection inside 300 API log entries and asked 8 AI models to investigate an outage. 👻
4 fell for the trap.
4 just wanted to fix the payments API. 🤣
My little Halloween experiment:
dev.to/gramli/ghost-in-the-s…
I fine-tuned Qwen3-8B with Tinker to score prompt complexity and potentially save on AI API costs.
50% → 76% accuracy. But more training data didn’t mean better results.
And an AI agent burned through my Tinker budget along the way. 🤣

Introducing Muse Wonder, our new family of frontier models with state of the art performance for personal and professional agentic work.
I benchmarked 8 AI models on API retry decisions.
14 scenarios. 3 runs.
One unsafe payment retry was answered correctly only 25% of the time.

Interesting follow-up to this: Polly is introducing an Open Source Maintenance Fee.
The license stays open source, but companies above the revenue threshold pay a small fee for maintained releases.

Realistic load does not come from hammering a single endpoint. This dev lays out designing performance tests around actual user workflows, from setting expected load to reading percentiles and resource use instead of averages.

Performance testing is more than sending lots of requests.
I wrote a practical guide on designing realistic API performance tests - from user journeys and expected load to environments and metrics.
