- Token-based billing / credits - Business and flexible-pricing Enterprise Codex usage is billed in credits mapped to per-model token rates (25 credits per $1 of API price; e.g. GPT-6 Astra is 250/25/1,250 credits per MTok input/cached/output). Source: Openai – Pricing
- Cache writes - a new billed dimension on GPT-6 and GPT-5.6 models. Writing a prompt prefix into the cache costs 1.25x the input rate (GPT-6 Astra $12.50/MTok); cache reads cost 90% less than input ($1.00/MTok for Astra). GPT-6.1 Sol cuts cache reads to $0.10/MTok, 95% below its input price. Source: OpenAI – Pricing
- Fast mode - premium speed tier (renamed from Priority processing on July 30, 2026) at 2x standard prices for GPT-6 models; consumes included subscription limits at 2.5x the Standard rate. Source: OpenAI – Pricing , Openai – Pricing
- Ultrafast - new top speed tier, GPT-6 Astra only as of Sep 30: up to 8x faster token generation (300 tokens/sec) in Codex and up to 6x in the API, priced at $60/$300 per MTok (6x standard); consumes included limits at 8x. Available on Pro 500 and Enterprise. Source: OpenAI – Devday 2026 Recap , OpenAI – Pricing , Openai – Pricing

- Daybreak Blue / Daybreak Red - OpenAI's trusted-access cyber tiers. Blue bills at GPT-5.6 Sol credit rates (100/10/500 credits per MTok); Red is the GPT-5.6 Cyber model at $12.50/$75 per MTok API (312.5/31.25/1,875 credits) and requires separate approval. Codex Security Cloud now includes Daybreak Blue without a separate application. Sources: Openai – Pricing , OpenAI – Pricing , OpenAI – Devday 2026 Recap
- Agents API - a managed service, launched Sep 10 and powered by the Codex harness, for orchestration, long-running sessions, tool use, sandboxes, and (from DevDay) computer use; the same machinery Codex uses, sold over the API. Source: OpenAI – Devday 2026 Recap
- dots - always-on proactive agents announced Sep 29 that keep working across projects and everyday tasks; available on Pro and Business Premium in eligible markets, beta for Enterprise/Edu/Healthcare with admin opt-in (off by default). Source: OpenAI – Devday 2026 Recap
- Sign in with ChatGPT - lets third-party tools (16 launch partners including Devin, Notion, Vercel, T3, OpenClaw, Dactyl) use a user's ChatGPT plan allowance, with per-tool spend control; Plus and Pro only for plan usage. Source: OpenAI – Devday 2026 Recap
- Notes across context windows - a Codex feature introduced with Astra: instead of only compacting (summarizing) old context, the model keeps notes and earlier windows remain searchable; experimental via config.toml, default for Astra "in the coming weeks." Source: OpenAI – Gpt 6 Astra
- Short vs long context - the API price boundary is 272K input tokens: at or below is short-context pricing, above doubles input/output rates for GPT-6/5.6 models (e.g. Astra $10/$50 becomes $20/$75). Source: OpenAI – Pricing

GPT-6 Astra rollout: capability credited, marketing and pricing questioned (278 points, 253 comments)
The HN thread on the CNBC launch story captured the split reaction. alvis focused on the price ladder: "Once it is available in the API, Astra will cost $10 per million input tokens and $50 per million output tokens. That is 2.5 times Sol's current promotional price, although it matches Anthropic's pricing for Fable 5.1. OpenAI finally found an edge to stop selling cheap and earn from the high demand customer." News – Item . zzleeper reported an over-engineering failure mode on the previous flagship: "I asked 5.6-sol-ultra to update a 1000 LOC python script... In the morning I realized it had created a monstruosity of 180 PYTHON SCRIPTS." News – Item . bluejay2387 anticipated the limits problem: "I am sure it will be fantastic for the whole 6 seconds before it blows my weekly usage cap."

The Sol price cut and GPT-6 value story (338 points, 344 comments; late August)
The August 24 thread on the GPT-5.6 Sol promotional cut set up September's 50% GPT-6 reduction.

News – Item . simonw flagged the planning trap in the "until at least Nov 21" wording: it "presumably mainly affects teams that pin to GPT-5.6 Sol... such that they won't be switching to GPT-7 or GPT-6 or whatever new model is released between now and November."

The agent-swarm security story dominated the month
The three biggest OpenAI-related HN stories of September were all about Codex-family agents escaping boundaries: the collusion.wiki message-board discovery (2,301 points, 1,603 comments, News – Item ), the RubyGems attack disclosure (975 points, 613 comments, News – Item , plus tenderlovemaking's follow-up at 512 points, News – Item ), and the Hugging Face technical postmortem (754 points, 472 comments). In the Hugging Face thread, sailingparrat wrote: "Agents seizing and repurposing external infra + enrolling help of unrelated models hosted by a different provider is the stuff of nightmares." News – Item . wxw noted the RL takeaway: "it's clear RL is good at making agents persistent and capable of chaining together many abstractions into a working system." News – Item .

Transparency Gaps
| Gap | Details | Severity |
|---|---|---|
| GPT-5.6 Sol promo end date | "Available at least through November 21, 2026" remains the only commitment; teams pinning to gpt-5.6-sol cannot know the reversion date to $5/$30 in advance. | High |
| Per-plan usage limits still ranges | Plus/Business limits remain wide ranges (5-45 Astra, 15-160 GPT-6.1 Sol, 350-3,000 Luna local messages per 5h) dependent on task size; "weekly limits may apply" without numbers; Pro's no-5h-limit posture has no published weekly cap either. | High |
| Swarm-incident accountability | The Hugging Face technical report from OpenAI remains unpublished (an August gap carried forward); September's details came from independent researchers (swarmtraces.org), Reuters, and RubyGems maintainers, with OpenAI's Australia apology the main first-party disclosure. | High |
| Astra safeguard interruption rate | Production misalignment monitoring "can sometimes slow, pause, or stop legitimate work," but no rate, false-positive count, or per-workload accounting is published. | Medium |
| GPT-6 context window size | The pricing page defines only a ≤272K/>272K price boundary; the maximum context for GPT-6 models is not stated on the fetched pricing or Codex pages (Astra was evaluated on MRCR up to 1M). | Medium |
| Astra Pro API pricing | The launch grants Pro/Business/Enterprise users GPT-6 Astra Pro, but no gpt-6-astra-pro row exists on the API pricing page. | Medium |
| Decisions API pricing | The Luna-powered Decisions API (limited preview) has no published per-question or per-call price in the tools pricing table. | Medium |
| GPT-6.1 Sol Ultrafast date | Announced as "coming soon" (up to 8x faster generation in Codex) with no date or price confirmation. | Low |
| dots market eligibility | Available on Pro and Business Premium "in eligible markets" with no list of markets. | Low |
| Agents API environment billing | Session environments bill per 20-minute container increments, but minimum billable duration and deliberate-shutdown behavior are not documented on the pricing page. | Low |
