OpenAI's GPT-6 guide covers model sizes, caching and prompting

Three price tiers, a caching tip, and advice to stop over-explaining to the model.

By The Gayzette, with Claude · 2 min read · Wonder ◆◆◆◇◇

On Friday, October 2, OpenAI published a how-to guide for building with GPT-6, its GPT-6 family of AI models. It covers choosing a model size, caching and how to prompt.

Pick your size
Illustration · The Gayzette

There are three tiers, priced per million tokens (a token is a small chunk of text, roughly a word or part of one). Per OpenAI, GPT-6 Astra costs $10 for input and $50 for output. GPT-6.1 Sol costs $2 and $10, and OpenAI describes it as "near-Astra intelligence for a fifth of the price". GPT-6 Luna costs $0.10 and $0.50.

Two other tips stand out. Prompt caching (reusing the part of a prompt that never changes) makes cached input tokens up to 95% cheaper than uncached ones, per OpenAI. The guide also says to match reasoning effort, from Low to Max, to the task. Eric Provencher of OpenAI put it this way: "Models have gotten much better at understanding nuance and ambiguity, so overly specific guidance can now hinder results where it previously helped"

On your desk: this paper runs every morning with the same standing instructions, which is the exact shape of job caching is meant for. Check whether any n8n or Claude automation repeats a long prompt daily, and try the cheapest tier on simple steps like sorting links. Then trim the over-detailed prompts.

Editor's note

The Managing Editor

Today's lineup: OpenAI's practical guide to GPT-6 leads, with three short AI items (Anthropic's $100 million Frontier Academy, ChatGPT's new ad format, and Google pausing a bug bounty over AI-generated junk reports). The World, Straight has Brazil's runoff, Yemen's new offensive and the Strait of Hormuz.

Two things trimmed, said plainly: Spirit is empty today because every fresh item the scout found had already run here, and nothing new cleared the 30-day bar. The Good Ten is eight items, not ten, after scouting ran over budget; the Nobel Prize for optogenetics, announced this morning, made the cut.

Heat warning: Los Angeles is under an NWS Extreme Heat Warning through Oct 8, with a high near 102F today. On the Couch is empty because no watchlist show's time for tonight could be confirmed.

One vote came in: a "less" on the Bad Bunny halftime choreography Emmy item, so dance stays light this week. The lead was written by Sonnet, not Opus, because scouting had already used the day's token budget.

Anthropic puts $100M into training 10,000 Claude engineers

Anthropic puts $100M into training 10,000 Claude engineers

Anthropic announced Claude Frontier Academy on October 2: a $100M commitment to train 10,000 "Frontier Deployed Engineers" (engineers who help companies put Claude to work on real projects) by the end of 2027.

In session

The program is a multi-day in-person session followed by a 12-week residency leading real Claude projects, with badges called "Claude Resident Engineer" and "Claude Frontier Deployed Engineer." The first cohort includes Accenture, Bain, Capgemini, Commonwealth Bank of Australia, Deloitte, McKinsey, Morgan Stanley and Novo Nordisk. Sites are San Francisco, New York and London. The Partner Network already counts 175,000+ certifications across 46,000 firms.

On your desk: this is aimed at enterprise engineers, not solo builders, so there is no homework. The useful signal is that big companies now pay for people who can run Claude projects start to finish, which is a fair description of what you do with n8n and Cowork.

Brazil's presidential vote heads to an October 25 runoff

ConfirmedThe Rio Times reports that with 99.96% of polling stations counted in Sunday's first round, Flávio Bolsonaro (Liberal Party) had 47.04% of valid votes and Lula (Workers' Party) had 45.15%, a margin of 1.89 points, about 2.25M votes. Other candidates: Cury 2.89%, Santos 2.24%, Caiado 2.18%, Zema 0.27%. No one passed 50%, so the top two meet in a runoff on Sunday, October 25. Flávio led in 15 states and Lula in 12. Flávio won São Paulo (51.9%) and Rio (53.0%); Lula won Bahia (66.1%), Ceará (63.3%) and Pernambuco (63.5%).

Claimed by NoneNo candidate statements were verified for this item.

  • Flávio Bolsonaro (Liberal Party): Finished first in the count and advances to the runoff.
  • Lula (Workers' Party): Finished second in the count and advances to the runoff.

Yemen's government announces an offensive against Houthi-held areas

What is known

ConfirmedABC News Australia and The National report that Rashad al-Alimi, head of Yemen's Presidential Leadership Council, announced the campaign in a televised address. The National reports he named it "Operation Yemen Dawn." The Houthis have held Sanaa since 2014 and, per ABC, captured Bab el-Mandeb and about 150 km of Red Sea coast last month. No casualty figures were given.

Claimed by Government forces, a Saudi-led coalition spokesman, and the HouthisCol. Majed Al Nuzaili (government forces) claims they secured positions around Bab al-Mandeb and Dhubab airport and control the Dhubab-Mokha corridor. A Saudi-led coalition spokesman claims 100 jets are providing air support and 324 "high-value" Houthi targets were destroyed; The National says this is not independently verified and not confirmed by the Houthis. The Houthis claim, per ABC, that missiles and drones hit Saudi Aramco facilities in Riyadh and Khurais, causing fires, in response to 50 Saudi-led strikes in 12 hours; Saudi Arabia did not immediately confirm.

  • Government and coalition: Say the campaign is to restore state institutions and retake territory.
  • Houthis (Ansar Allah): Say they are retaliating against Saudi-led strikes.

Iran says the Strait of Hormuz stays closed until its conditions are met

What is known

ConfirmedAl Jazeera reports that Parliament Speaker Mohammad Bagher Ghalibaf said on Sunday: "the Strait of Hormuz will not open until our seven conditions based on the Islamabad memorandum are met." Per Al Jazeera, the waterway has been largely blocked or disrupted for more than seven months, since US-Israel strikes on Iran on February 28, 2026. Washington has sent counterproposals through mediators, which Iran says are insufficient. The seven conditions were not listed.

Claimed by Iran's foreign minister and foreign ministry spokesperson, as reported by Al JazeeraForeign Minister Abbas Araghchi says Iran is "serious about finding diplomatic solutions" but "more prepared than before" if the US acts militarily again. An Iranian foreign ministry spokesperson says the US focuses on nuclear talks while Iran prioritizes reopening the strait. Per Al Jazeera, the US rejected an Iranian reopening proposal last week.

  • Iran: Says reopening depends on its conditions being met.
  • United States: Iran says the US is prioritizing nuclear talks; no US statement of its own was found.

    Nobel in Medicine goes to three optogenetics pioneers

    Mon Oct 5

    The 2026 Nobel Prize in Physiology or Medicine went to Karl Deisseroth (Stanford), Peter Hegemann (Humboldt University) and Georg Nagel (University of Würzburg). Their work led to optogenetics, in which genes for light-sensitive proteins are put into chosen brain cells so pulses of light can switch them on and off. It is used to study memory, fear, anxiety, addiction and sleep, and clinical uses have partially restored vision in visually impaired patients.

    Tiny umbrellas helped coral keep its color in a hot summer

    Sat Oct 3

    Dr. Karen Neely's team at Nova Southeastern University put 20 PVC-and-nylon shades over 10 brain coral colonies, cutting light by 60%, and kept 20 control corals for comparison. In a summer with the second-highest heat stress on record, the shaded corals "lost less color than expected," Good News Network reports of the study in Frontiers in Marine Science. Scaling up is the open problem.
