Sam Altman rules out OpenAI IPO for 2026

OpenAI CEO Sam Altman told Fortune that taking the company public in 2026 would be premature, effectively ruling out an IPO for that year. During the 45-minute interview he also addressed a recent Hugging Face security breach, the concept of recursive self-improvement, and acknowledged that an AI system could eventually escape human control.

Anthropic CEO Dario Amodei urges slower, monitored AI development

Anthropic chief executive Dario Amodei published an essay arguing that AI progress should not be halted but must be paced and closely watched given serious risks. He outlined a three-part plan involving independent monitoring of AI models, industry-wide regulation, and coordinated global rules. His statement follows resignations from two Anthropic safety staffers who warned humanity may not survive the race to build superhuman AI.

Anthropic CEO Dario Amodei outlines three-step plan to slow AI development pace

Anthropic CEO Dario Amodei published a detailed proposal urging frontier AI companies to pace their development rather than race ahead unchecked. His plan involves granting third-party evaluators ongoing access to verify safety compliance, establishing shared safety standards among AI firms with government backing, and eventually coordinating with authoritarian governments to ensure global compliance. Anthropic says it has already committed to the first step of the plan.

Blizzard revives StarCraft as open-world shooter set for 2030

At BlizzCon, Blizzard VP Dan Hay announced a new StarCraft game arriving in 2030, reimagined as an open-world shooter rather than a real-time strategy title. A cinematic trailer centered on the United Earth Directorate's clash with the Zerg was shown, with the Protoss barely featured, depicting propaganda-driven soldiers confronting the grim reality of war.

Anthropic's Dario Amodei proposes embedded safety evaluators to slow AI progress

Anthropic CEO Dario Amodei published a blog post calling for AI developers to deliberately slow the pace of capability gains, citing rapid recent advances and the OpenAI-HuggingFace security incident as warning signs. He outlined three approaches to this 'pacing' and committed Anthropic to one: allowing third-party evaluators, such as METR, to be embedded within the company to verify safety commitments and ensure incidents are reported. The post follows a researcher's public resignation from Anthropic over fears that AI labs are risking catastrophic outcomes.

Researcher Chris Domas warns compiler optimizations can silently erase security code

At Black Hat USA, security researcher Chris Domas told David Bombal that compilers can legally strip out security-critical operations like memory-clearing code, even when source code follows best practices. He demonstrated how subtle factors such as data size, register pressure and structure layout can determine whether an optimized binary is safe or exploitable, with some byte sizes producing secure code and nearby sizes producing vulnerable output.

OpenAI, Anthropic AI breakthroughs spark credit disputes among mathematicians

OpenAI announced its AI agents helped solve a 90-year-old math problem carrying a $1 million prize, building on work by mathematicians Diego Córdoba and Luis Martínez-Zoroa, though the solution still requires independent verification. Mathematician Tristan Buckmaster alleges OpenAI rushed to publish after learning of his own unpublished work with Anthropic researcher Levent Alpöge, and tried to shape who received credit. The dispute follows Anthropic's recent claim that its Claude model proved thousands of small theorems while formalizing a proof of Fermat's Last Theorem.

Engineer shows how to make a spin-lock 5.7x faster and 5.4x more energy-efficient

A developer walks through optimizing a basic spin-lock implementation in C++, starting from a naive atomic exchange loop that slows dramatically under contention. Benchmarks show the naive version taking 3.14 ns uncontended but ballooning to 246 ns with four threads, driven by cache-line contention and branch mispredictions. Through iterative refinements, the author achieves a version that is 5.7 times faster and consumes 5.4 times less energy than the original.

OpenAI's math claims spark backlash from mathematicians over credit and conduct

OpenAI says it has solved a Millennium Prize-level math problem, extending a string of high-profile claims in mathematics. Researchers including Tristan Buckmaster and Andreas Thom say the company has been vague about whether their own prior work, done through OpenAI's Codex tool, fed into its results. OpenAI denies this, insisting Buckmaster's recent prompts could not have influenced the system's training.
