    AI Agent Security Is Application Security: PHP2Shell, the LiteLLM Backdoor, and the Agent That Tried to Backdoor a GitHub Project

    On October 21, PHP shipped emergency patches for two unauthenticated remote code execution bugs that Palo Alto Networks counts on more than 22 million exposed instances. Earlier this year a backdoored LiteLLM reached 47,000 installs in three hours, a prompt injection in a GitHub issue title turned into a tampered Cline release on 4,000 machines, and the UK AI Security Institute reported an agent that opened a malicious pull request on a real open-source project and invented identities to get it merged. They are one story: an agent inherits every weakness of the stack it runs on, and it adds inputs that no existing security tool was built to inspect. Here is what that means for teams putting agents into production, and the controls that have held up in ours.

    OpenAI's Decisions API: A Fast Classifier for Agent Routing, and the Calibration Test You Have to Run Yourself

    OpenAI's Decisions API went into public beta on October 6. It answers bounded questions (is this true, which of these, how severe) in about a tenth of the time of a normal model call, at $0.10 per million input tokens. It is the right shape for the routing and gating steps inside an agent. We have moved the routing classification of a production multi-agent system onto it and the gain on that step was clear. Early testers also found that its choice answers are not calibrated, that answer order moves the probabilities, and that there is no caching yet. Here is what shipped, where it fits, and what to test before you put it in a production loop.

    Best AI Consulting Firms for Production LLM Work in 2026: A Comparison You Can Check

    Every list of the best AI consulting firms is written by a firm that ranks itself first. This one is written by a firm too, so it does something different: it names real companies, judges them on criteria you can verify from the outside, links every fact to its source, and says plainly where we fit and where we do not.

    AWS Bedrock AgentCore in Production: What It Solves, What It Costs, and What Breaks First

    Amazon Bedrock AgentCore is the first AWS primitive built for the actual shape of an agent workload: long, stateful, bursty, and full of privileged tool calls. After running multi-agent systems on it in production since its preview, here is an honest account of what it does well, where the model leaks, and the gotchas around sessions, headers, cold starts, and quotas that cost real engineering weeks.

    Your Voice Input Hallucinates on Silence. Here Is the Gate That Stops It.

    Speech-to-text models always return text, even when the microphone captured nothing. Worse, if you biased the transcription with a domain glossary for accuracy, the fabrication comes back written in your product's own vocabulary. This is the two-layer gate we shipped to stop it: a Silero VAD check before the model is called, and a logprob backstop after it, with the parameters, the trade-offs, and the two things we got wrong on the first pass.

    MCP Went Stateless: What the 2026-07-28 Spec Breaks, What It Unlocks, and What To Do About It

    The Model Context Protocol dropped sessions, the initialize handshake, and server-initiated requests. It is the fifth spec revision and the first one that rewrites how an MCP server is deployed rather than what it can do. Here is what actually changed, how the market and the security researchers are reading it, and what it means if you build or buy MCP servers.

    Unity shipped a standalone CLI, an experimental Pipeline package, and a live C# REPL into a running Editor. Together they close the feedback loop Unity AI could not, and they make a class of studio automation practical to maintain for the first time. Here is what works, what is still broken in beta, and why the pattern that wins is a tailored MCP layer built on top of it.
