OpenAI’s new Decisions API, announced at DevDay and built on GPT-6 Luna, picks fast answers from a fixed list, much like TypeSafe AI’s Jev. We explain what OpenAI announced, how it compares with Jev, what a decision model is, why it could cheaply supervise misbehaving AI agents, the numbers from the Jev Sentinel demo and what developers should test.
OpenAI’s shareable ChatGPT profiles are rolling out to every plan. They show message counts, Work and Codex token usage, streaks, your top plugins and up to 12 Sites. Personal profiles start private, but Business profiles are shared with coworkers by default. We set out what a profile reveals, the Enterprise contradiction, and what to check before sharing.
OpenAI’s DevDay features copy five of the six jobs an app store does inside ChatGPT: discovery, distribution, interface, identity and review. The sixth, payment and commission, is missing. We map each layer, show what a developer keeps from a sale and explain how plan sharing turns the usual economics upside down.
Minutes after OpenAI announced Dots, a viral post claimed Elon Musk’s xAI had bought dot.com to mock it. We checked the registry records, the redirect and the timeline: the record changed 63 days before the announcement and 14 days before xAI launched Grok Bot, which is where the address leads.
OpenAI’s new $500 plan is the only personal ChatGPT tier with Astra Ultrafast, and it arrived as the $200 plan lost half its allowance. We check 18 claims against OpenAI’s own documents, show that every rung from Plus upward now costs $20 per unit of usage, and work out what Ultrafast does to a 25x allowance.
OpenAI used DevDay to turn ChatGPT into an app store for AI, with plugin extensions, a rebuilt directory, Sign in with ChatGPT and an enterprise Marketplace. We explain why it wants a store now, how money moves, how this differs from the GPT Store, and the safety concerns, from agent incidents to plugin updates that skip human review.
Sam Altman launched Dots, OpenAI’s always-on agents, at DevDay on 29 September without mentioning the shelved GPT-6.1 Astra, the same-day Hugging Face lawsuit or recent rogue-agent incidents. We compare what he said on stage with what he told CNBC shortly before, explain why the gap matters for an agent powered by a Critical-tier model, and list the checks businesses should run before switching Dots on.
OpenAI launched GPT-6.1 Sol at DevDay on 29 September at one-fifth of GPT-6 Astra’s token price, a day after it shelved GPT-6.1 Astra for ignoring instructions. We compare prices with Astra, GPT-6 Sol and Claude Opus 5.5, break down OpenAI’s benchmarks, read the system card’s Critical cybersecurity rating and alignment results, and explain when to switch.
OpenAI scheduled its DevDay 2026 keynote for 10am PT on 29 September at Fort Mason. Sam Altman used it to launch Dots always-on agents, GPT-6.1 Sol, the Ultrafast speed tier, a $500 Pro plan and more than 20 other products. We cover the schedule, every major launch and who can use it, what the leaks got right, the numbers OpenAI shared and what to do next.
A redacted announcement string shows OpenAI is working on Spaces, which TestingCatalog speculates could be a shared environment where people and AI agents work on generated artefacts. We set out what leaked, the DevDay sessions that point the same way, how it would extend Canvas, shared projects and workspace agents, and what businesses should decide first.
