Chinese AI company Z.ai has launched GLM-5.1, an open-source coding model it says is built for agentic software engineering. The release comes as AI vendors move beyond autocomplete-style coding tools toward systems that can handle software tasks over longer periods with less human input.
Z.ai said GLM-5.1 can sustain performance over hundreds of iterations, an ability it argues sets it apart from models that lose effectiveness in longer sessions.
As one example, the company said GLM-5.1 improved a vector database optimization task over more than 600 iterations and 6,000 tool calls, reaching 21,500 queries per second, about six times the best result achieved in a single 50-turn session.
In a research note, Z.ai said GLM-5.1 outperformed its predecessor, GLM-5, on several software engineering benchmarks and showed particular strength in repo generation, terminal-based problem solving, and repeated code optimization. The company said the model scored 58.4 on SWE-Bench Pro, compared with
Vibe coding gets you to a prototype. Spec-driven development gets you to production. As AI coding agents grow more powerful, the engineering community has quietly split into two camps: developers who prompt iteratively and hope for the best, and developers who write structured specifications first and let agents execute against them. The second group is shipping faster, with fewer regressions, and with code that survives review. This guide covers the 9 AI tools driving that shift in 2026 — from AWS Kiro's EARS-structured spec IDE to GitHub Spec Kit's 93K-star open-source workflow, to lean execution frameworks like GSD that have crossed 61K stars in under five months.

If you have spent time using AI coding agents — GitHub Copilot, Claude Code, Gemini CLI — you have probably run into this situation: you describe what you want, the agent generates a block of code that looks correct, compiles, and then subtly misses the actual intent. This “vibe-coding” approach can work for quick prototypes […]

Everyone is adopting AI coding tools. Engineers are writing code faster than ever. But are organizations actually delivering value faster? That’s not obvious. I wrote Enabling Microservice Success with a big focus on engineering enablement, guardrails, automated testing, active ownership, and light touch governance. I didn’t know AI coding agents were coming, but it turns […]
Attackers too are looking to cash in on the AI coding craze, adapting their supply-chain techniques to target coding agents themselves.
Many AI agents autonomously scan package registries such as NPM and PyPI for components to integrate into their coding projects, and attackers are beginning to take advantage of this. Bait packages with persuasive descriptions and legitimate functionality have cropped up on such registries, while packages that target names that AI coding agents are likely to hallucinate as dependencies are another attack vector on the horizon.
Researchers from security firm ReversingLabs have been tracking one such supply-chain attack that uses “LLM Optimization (LLMO) abuse and knowledge injection” to make packages more likely to be discovered and chosen by AI agents. Dubbed PromptMink, the attack was attributed to Famous Chollima, one of North Korea’s APT groups tasked with generating funds for the regime by targeting developers and users from the cryptocurrency and
A colleague told me something recently that I keep thinking about. She said, unprompted, that she appreciated seeing both sides of my AI conversations. Not just the output. The full thread. My prompts, the AI’s responses, the back and forth, the dead ends, the iterations. She said it made her trust me more. This piece […]
Infosys said the integration will be used to help its clients modernize software development, automate workflows and deploy AI systems, initially focusing software engineering, legacy modernization, and DevOps.
The week’s largest round was a $650 million financing for electric pickup truck maker Slate Auto. Other sizable investments went to spaces including drug development, autonomous public transit and software engineering.
Factory has secured $150 million in funding at a $1.5 billion valuation to expand its AI-driven coding platform for enterprise engineering teams. The round was led by Khosla Ventures, with participation from Sequoia Capital, Insight Partners, and Blackstone. Keith Rabois has joined the company’s board. Founded in 2023 by Matan Grinberg, the company develops AI […]
