- OpenAI makes the Decisions API generally available for fast bounded choices with GPT-6 Luna
OpenAI made the Decisions API generally available. Built with GPT-6 Luna, it focuses the model on questions with bounded answers so apps can classify, route or score from text, images and structured inputs, which OpenAI says can be up to 10× faster than Luna through the Responses API. Since beta it added GPT-Live integration, prompt caching, US/EU residency, native JSON inputs, images in instructions and up to 400 questions per request. Input is $0.10 per million tokens with no output-token charge.
- OpenAI lets developers choose which API service tiers each project can use

- OpenAI says GPT-Rosalind surfaced a drug-discovery lead linking cholesterol transport to neurodegeneration
OpenAI says GPT-Rosalind suggested that restoring cholesterol transport could protect neurons from degeneration. In mouse-brain data, disrupting DCTN1, a gene linked to the rare neurodegenerative disorder Perry syndrome, increased expression of genes involved in making cholesterol.
- OpenAI models are coming to Google Cloud, with GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna in private preview
OpenAI and Google Cloud are bringing OpenAI frontier models and Codex workflows to Gemini's Model Garden, available through Google Cloud Marketplace. According to The Decoder, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna launch as a private preview for enterprise customers, making Google Cloud the first major cloud to offer Gemini, Claude and OpenAI models together.
- OpenAI says its Patch the Planet coalition coordinated fixes for two critical PHP flaws, one found by Calif using GPT-5.6 Sol
OpenAI says it spent two months coordinating maintainers, researchers and security providers on two critical vulnerabilities in PHP. Calif found one using GPT-5.6 Sol under OpenAI's Patch the Planet initiative, and Wiz independently found and reported both. PHP released fixes on Oct 21, and OpenAI is sharing a PHP version checker as a Codex skill.

- A judge dismisses Ann Altman's sexual abuse lawsuit against OpenAI CEO Sam Altman with prejudice, per The Verge
US District Judge Zachary Bluestone on Tuesday dismissed the lawsuit Ann Altman filed last year accusing her brother, OpenAI CEO Sam Altman, of sexually abusing her during her childhood, The Verge reports. The judge wrote that she had failed to appear for an independent medical examination, and the case was dismissed with prejudice, so it cannot be refiled.
- OpenAI releases MultiLangBench and says its latest models are far better at COBOL, Fortran and other low-resource languages
OpenAI introduced two evaluations for low-resource programming languages: MultiLangBench, which asks a model to build a SQLite-compatible database engine in each of 20 languages, and a COBOL migration test that requires byte-for-byte output parity after porting programs to C++, Java, Kotlin, Python or Rust. OpenAI says GPT-6 Astra averaged an 87.4% test pass rate on MultiLangBench, up from 26.8% for GPT-5.6 Sol, and GPT-6.1 Sol reached 86.6% on COBOL migration at low reasoning effort and 97.9% at higher effort, versus 5.4% for GPT-5.6 Sol. It is releasing the MultiLangBench setup and test suite on GitHub. The results are OpenAI's own.
- OpenAI's desktop app now lets you edit previous messages within a thread, Tibo says
Tibo (@thsottiaux) said on Day 14 of his daily updates that users can now edit previous messages within a thread in the desktop app, calling it a small quality-of-life improvement that had been requested for a long time and took too long to ship.
- Three 'Aurora' alpha image models briefly appear in OpenAI's API and turn up in Arena tests, unconfirmed by OpenAI, per TestingCatalog
TestingCatalog reports that three model references, aurora-red-alpha, aurora-green-alpha and aurora-blue-alpha, briefly appeared in OpenAI's API and were removed shortly after, then turned up generating images in blind Arena tests. LuminaBench says it tried the red and green variants in Arena and got cat portraits from both; both outlets guess this could be GPT-Image-3, which they say is speculation. OpenAI has not confirmed the models.
- OpenAI raises GPT-6.1 Sol default context to 500k in Codex and Work, and drops long-context fees on subscriptions
As OpenAI Codex head Tibo Sottiaux wrote on X (Day 7 of the shipping series), GPT-6.1 Sol's default context length in Codex and Work is now 500k tokens, up from 272k — about an 80% increase — to cut compaction and help long-context tasks. A follow-up post said OpenAI is not charging long-context fees for GPT-6.1 Sol when usage is drawn from a subscription. He said defaults will go higher later.
- OpenAI says it parted ways with three researchers over sensitive-information policy violations, not safety concerns
In a note from its research leaders posted by OpenAI Newsroom on X, responding to the open letter from the three fired researchers, OpenAI says it parted ways last week with Jasmine, Mikita and Tomek after an investigation found they violated clear policies on handling sensitive information, and that it stands by the decision not to continue their employment. It says the decisions were not about raising safety concerns or speaking out, and that it has not terminated employees for raising concerns. OpenAI says it is finalizing contracts with third-party safety assessors and will announce details in the coming weeks. It agrees with the researchers' letter that preserving the monitorability of frontier models requires an industry-wide commitment, citing its Monitoring Monitorability publications, open-sourced monitorability evals and the GPT-6 Astra system card.
- Fired OpenAI safety researchers publish open letter: OpenAI cannot make AI safe on its own
Tomek Korbak, Jasmine Wang and Mikita Balesni, who say they are the three safety and alignment employees fired from OpenAI last week, published an open letter addressed to OpenAI's Safety and Security Committee, Safety Advisory Group and Mission Advisory Council. They say the firings are chilling the open culture OpenAI has prized, and that they acted in line with OpenAI's mission and within the working norms of the time. They say they were not the source of the leak to The Information, and give their own accounts of the Hugging Face incident investigation, Mikita's cross-company monitorability work and Jasmine's delegated access to an executive's email. They urge OpenAI to follow through on commitments to embed third-party safety auditors, to preserve the monitorability of frontier models, and to publicly reaffirm an open culture for raising safety concerns internally and externally.
