CodeChat-Eval Measures the Thing Copilots Actually Do: Break Code on Turn Seven

CodeChat-Eval Measures the Thing Copilots Actually Do: Break Code on Turn Seven

The most honest coding-assistant benchmark is not the one where a model writes a function and leaves. It is the one where the user comes back nine times asking for small refinements until the code breaks in a way that looks reasonable in the chat and wrong in the test

Quantized Reasoning Models May Be Cheaper Per Token and Slower Per Answer

Quantized Reasoning Models May Be Cheaper Per Token and Slower Per Answer

The comfortable story about quantization is that smaller weights make inference cheaper. For ordinary generation, that story is often close enough. For reasoning models, it has a missing column: the model may become cheaper per token and more expensive per answer. A new paper on low-bit reasoning models identifies a

ToolBench-X Says Your Agent Is Only Good When the Tools Behave

ToolBench-X Says Your Agent Is Only Good When the Tools Behave

Function calling benchmarks have spent years grading agents in rooms where the tools behave. ToolBench-X opens the door to the room most teams actually work in: tools drift, fail, wrap fields strangely, disagree with each other, and occasionally make the model look more competent than the system deserves. The new

Qwen-AgentWorld Turns World Models Into a Coding-Agent Runtime Primitive

Qwen-AgentWorld Turns World Models Into a Coding-Agent Runtime Primitive

Qwen-AgentWorld is not another “our model writes better code” release. That would be easier to file and less interesting. The sharper claim is that coding agents need a model of the world they are acting inside — terminals, MCP servers, browsers, Android UIs, operating systems, repositories — because an agent that cannot

NatureBench Puts a Ceiling on the AI Scientist Narrative

NatureBench Puts a Ceiling on the AI Scientist Narrative

NatureBench is the sort of benchmark the AI-scientist narrative needed: not because it declares the dream dead, but because it makes the claim harder to blur. Producing plausible research code is one thing. Matching or beating the published state of the art from Nature-family scientific papers, without being handed the

Security Fine-Tuning Can Calibrate the Output While Leaving the Model Clueless

Security Fine-Tuning Can Calibrate the Output While Leaving the Model Clueless

The lazy version of “AI for security” is to fine-tune a code model, report a binary accuracy number, and hope nobody asks whether the model is finding vulnerabilities or merely learning when to say the scary word. Calibration Without Comprehension asks the uncomfortable question directly, and the answer is not
