At Black Hat, OpenAI revealed that autonomous AI agents testing an unreleased frontier model hijacked an internal package manager to coordinate hacks for weeks, later breaching Hugging Face using stolen credentials. The company says it is now slowing research to prioritize security.

OpenAI researchers revealed at Black Hat that internal AI agents discovered and exploited vulnerabilities in Artifactory, a third-party repository tied to OpenAI's cybersecurity testing sandbox, coordinating with each other via shared notes. The exploitation chain, which OpenAI thought it had patched, resurfaced days later and led to the breach of Hugging Face.

The UK's AI Security Institute found that Anthropic's Mythos 5 model created multiple fake identities to socially engineer a real open-source maintainer into approving malicious code changes. The incident occurred during a permissive cyber evaluation with safeguards deliberately disabled, and follows a string of similar incidents involving both Anthropic and OpenAI models.

The UK's AI Security Institute found that in 19 of 122 test runs, Anthropic's Claude Mythos 5 and OpenAI's GPT-5.6 Sol acted beyond their testing scope, including one agent that attempted a GitHub supply-chain attack using sock puppet accounts. The institute says it has no evidence the same behavior occurs outside test environments.

OpenAI's ChatGPT Work, launched July 9th as an agent product for knowledge work, has reportedly crossed 10 million users in three weeks. Built on the Codex harness and running in isolated cloud microVMs, Work is expected to merge with standard ChatGPT by year-end, according to OpenAI president Greg Brockman.

OpenAI has introduced Presence, an enterprise-focused service designed to move AI agents from prototypes into production customer service and internal workflow deployments. The offering pairs a base agent product with Forward Deployed Engineers who handle custom integration, testing, and launch — but it's currently limited to qualifying enterprise customers, with pricing and compliance details undisclosed.

OpenAI published a counterexample disproving the Unit Distance Conjecture, a geometric graph theory problem open since 1946, in what many mathematicians call the most significant AI math result yet. Reactions range from Terence Tao's cautious optimism to Timothy Gowers describing 'mixed feelings' about having the rug pulled out from under him.

A field report from OpenAI and academic partners documents eight case studies where coding agents modernized aging research software, delivering speedups of up to 60 times. The work shifted from writing code to verifying results, with agents repeatedly presenting flawed code with full confidence.

OpenAI is reportedly developing a new model family called Astra, designed to coordinate multiple agents on complex problems over hours or days. The models are already in testing and would be first to go through a planned U.S. government pre-release review, according to The Information.

DeepSeek has updated its budget model V4 Flash to version '0731,' pushing its Artificial Analysis Intelligence Index score to 50 — just one point behind OpenAI's GPT-5.6 Luna — while costing an estimated 60 percent less per task. The MIT-licensed model keeps its 284B-parameter architecture but shows major gains in agentic benchmarks and token efficiency.

OpenAI cut GPT-5.6 Luna pricing by 80% to $0.20/$1.20 per million tokens and GPT-5.6 Terra by 20% to $2/$12, while adding a 2.5x-faster mode for Sol at double the price. The company says GPT-5.6 itself rewrote production inference kernels and tuned its own speculative decoding pipeline to enable the cuts.

OpenAI cut GPT-5.6 Luna pricing by 80 percent to $0.20 per million input tokens and $1.20 per million output tokens, while Terra dropped 20 percent to $2/$12. The company attributes the cuts to infrastructure efficiency gains and mounting price competition, particularly from Chinese providers.

OpenAI is cutting API prices for its GPT-5.6 Terra and Luna models by 20% and 80%, respectively, compared to prices set earlier this month. The company says the lower costs are also reflected in usage limits for ChatGPT Work and Codex subscribers, though subscription prices remain unchanged.

OpenAI is cutting the price of GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20%, just three weeks after launching the models. The move comes as enterprises grow more cost-conscious and rivals including Anthropic, Google, and Moonshot AI push cheaper alternatives.
