OpenAI’s Dots began as Codex, its coding agent. At TechCrunch Disrupt, Alexander Embiricos explained how the Codex app, ChatGPT Work and a single named character became an always-on personal assistant, plus what he said about proactive research, privacy controls, permission prompts and payments. We trace every step with OpenAI’s own launch posts.
Thomas Sottiaux, an OpenAI engineering leader associated with Codex and ChatGPT, attracted significant attention on X during September 2026. His public posts covered product updates, coding tools, service availability, and developments across OpenAI’s AI ecosystem. His profile identifies his work with Codex and ChatGPT at OpenAI. The claim that Sottiaux became September’s “most popular X […]
OpenAI has rolled out Ultrafast mode for GPT-6.1 Sol in the API, Codex and ChatGPT Work, promising up to 8x faster generation than Sol Standard. It costs $12 per million input tokens and $60 per million output, six times Standard, and in ChatGPT it is limited to Pro $500 and eligible Enterprise and Edu plans. We cover the measured speed, every price tier, the 8x allowance burn, EU residency, the Cerebras question and when the premium pays.
OpenAI will add an invisible textGrain watermark to ChatGPT and Codex text in the EU to meet the AI Act. We break down how it works, OpenAI’s own detection and quality numbers, why the detector is gated, how it compares with Claude’s worldwide watermark, and what UK and EU organisations should do.
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.
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.
A ChatGPT Pro upgrade screen and OpenAI’s own web code both name the company’s next product: “o, your always-on assistant”. We checked the code ourselves. This article sets out what leaked and when, what the evidence says o would do, which Pro plans include it, the Codex Persistent mode work behind it, how it compares with Muse, Grok Bot and Conway, and the risks businesses should plan for before DevDay.
ChatGPT Pro Max, a $500-a-month ChatGPT plan, appeared in OpenAI’s web app code and in a Codex commit on 24 and 25 September 2026. The same week Google released Gemini 3.8 Live and made Live Avatar generally available. This article covers the leak evidence, the renamed Pro ladder, the Gemini benchmarks and pricing, and what businesses should do.
A new OpenAI Platform onboarding screen spotted on 23 September 2026 offers three plans: Free, Prototype starting at $5 and Accelerate starting at $50. The headline says they are for AI app hosting, but no plan card mentions hosting, and the prices match OpenAI’s existing Tier 1 and Tier 2 thresholds exactly. This article reads the screen line by line, works through what $50 buys in tokens, sets out what OpenAI already hosts for developers, and lists what DevDay on 29 September needs to answer.
Meta’s terminal coding agent Muse Code got its AIxploria card on 18 September 2026, with a 4.4 rating from twelve votes and a “#87 in Developer Tools” badge. We checked every claim against Meta’s documentation. The worktree sub-agents, event log, token rates and Everyday allowance all match. The High and Power plan multipliers do not: Meta’s docs say 5x and 20x, the card says 3x and 10x, which halves the real unit price of the top plan. The card also misses the contributor tier’s 100-request rate limit and two Windows gaps.
