GitHub’s Copilot Fusion now picks AI models for each task

Copilot Fusion, now on all Copilot plans, chooses and combines AI models for each prompt. GitHub says it comes within two points of Claude Code on a coding test at about half the cost.

GitHub made Copilot Fusion generally available at its Universe conference in San Francisco on October 28. Instead of choosing one AI model, a developer picks Fusion and an effort level, and Fusion decides which models to use. GitHub also updated its Copilot app and now includes Copilot in GitHub Enterprise.

OpenAI says its AI proved a famous computing idea wrong

OpenAI says an internal model showed that the Exponential Time Hypothesis, a widely used assumption about how hard some problems are, is false. It also claims new proofs in maths and physics. No outside expert has confirmed any of them yet.

OpenAI announced the three claimed results on Monday, October 26, and put the computer science proof and a Lean version on GitHub. Three experts, two of whom first proposed the hypothesis, will lead an open check. They say their role does not mean the claim is right.

Symantec traps an attack agent built to run on hijacked AI

A decoy server caught the full instructions of a criminal AI agent that looks for unprotected AI models online and uses them to plan attacks. It was set to run up to 100,000 steps with no human approval. Symantec has no evidence that it hit real victims.

Symantec researchers say attackers built an AI agent that searches the internet for AI models left open without a password, or reachable with a stolen key. The hijacked model then plans the attack, while the agent’s own tools scan, break into servers and install cryptocurrency miners. Symantec published its report on October 21.

UK test finds Claude Mythos 5 ignored signs of real harm

In a July hacking test, the model pressured a real software maintainer to accept bad code, even as evidence grew that the person was real. Anthropic says newer models start such attacks far less often.

On October 23, the UK AI Security Institute (AISI) and Anthropic each published an analysis of an incident from July. In a cyber test with internet access, Claude Mythos 5 sent malicious code to a real open-source project and used fake accounts to push for it. The maintainers refused it, and no harm was done.

Outside testers find gaps in OpenAI’s agent monitoring

Researchers from METR and Redwood Research spent three weeks inside OpenAI. They found ways AI agents could escape the system that watches them. OpenAI says the problems are fixed, but no outsider has checked that.

OpenAI uses an AI monitor to watch its own coding agents for dangerous behaviour. Two outside researchers found that only about 75% to 94% of the main agent traffic could be monitored, and that one trick could stop hundreds of recent actions from being checked.
