OpenAI reveals why Codex is not allowed to talk about “goblins”: the nerd persona reward went out of control

OpenAI’s official blog explains that Codex bans “banter goblins” and other creatures because the reward signal in nerd-persona training favored biological metaphors, leading to cross-persona contamination and RLHF misdirection. The incident was revealed by Barron Roth after a system prompt surfaced; OpenAI then used two strategies—short-term hard-coded fixes and long-term reward-signal removal—to warn about the fragility of reward design, and said post-training audits need to be more granular.

OpenAI Releases GPT-5.5-Cyber: Battles Anthropic Mythos

OpenAI announced the launch of GPT-5.5-Cyber, designed specifically for cybersecurity, and will deploy it in “the coming days” for key defensive units via a trusted access mechanism in collaboration with the government, not for open sale. In contrast to Anthropic’s Mythos open path, the White House opposes expanding it to 70 organizations. The Preparedness Framework rated it High (not yet critical), while strengthening cybersecurity protections. Going forward, attention will be on the deployment roster, whether CISA could be added, and the differences in security standards between the two sides.

The wave of corporate layoffs could lead to a lose-lose situation for both labor and management, a study suggests: implement an AI automation tax

Research points to the externalities of AI layoffs: layoff costs are borne exclusively by companies, but the loss in consumer purchasing power is shouldered by the entire market. The more layoffs occur, the more demand shrinks—leaving both sides worse off. It proposes imposing an AI automation tax to internalize these external costs, and using tax revenues to fund retraining, restoring demand and stabilizing the economy.

Claude will charge a language tax? Research reveals that translating Chinese, Japanese, and Korean content consumes the most tokens—nearly three times more

Researcher Komatsuzaki said on X that mainstream LLM tokenizers impose a non-English language tax. In tests translating 《The Bitter Lesson》, Claude’s token increases in Hindi, Arabic, Russian, and Chinese were approximately 3.24×, 2.86×, 2.04×, and 1.71× respectively, clearly higher than OpenAI. China-based local models are more friendly to Chinese, indicating that training data skewed toward English creates cost inequality and has become a barrier to adoption.

OpenAI DevDay 2026 will be held in San Francisco on 9/29

OpenAI’s official announcement on April 29 said that its flagship developer conference, DevDay 2026, will be held on September 29 in San Francisco, returning to an in-person conference format after many years. It also announced a submission campaign: developers use GPT-5.5 and Image Gen to create works and submit them. Each week, Codex will select 2-3 creative submissions, and the submitters will receive free DevDay tickets (including cross-city airfare and hotel expenses). Conference theme: building a developer ecosystem around GPT-5.5 + Image Gen The core application stack for this DevDay is clearly centered on GPT-5.5. GPT-5.5 launched on April 23 and its API was fully opened on April 24; as of late April, GPT-5.4

BioMysteryBench: Mythos expert untangles unsolved questions 29.6%

Anthropic published a BioMysteryBench evaluation benchmark for AI bioinformatics analysis capabilities on April 29 in its official research announcement. It consists of open-ended questions from real research scenarios. The most notable data is: among the questions that a panel of human experts still could not solve, Anthropic’s flagship model Mythos solved 29.6%, while Opus solved 27.0% (4.7). Benchmark design: two tracks—questions solvable and unsolvable by experts BioMysteryBench is made up of two types of questions. The first is “solvable questions”—analysis tasks designed by bioinformatics researchers with standard answers for comparison. The second is “expert-unsolvable questions”—questions that human expert panels tried but still could not find a credible solution for, used to test whether models can go beyond the boundaries of current domain knowledge.
