Sonnet 5 Promo Ends, List Price Holds

Anthropic's promotional pricing for Claude Sonnet 5 expired this week, returning usage to standard rates. The separate story is that Anthropic's scheduled list increase was cancelled, so Sonnet 5 stays at $21 per million input tokens and $102 per million output, per the vendor-traced price index published August 30...

Anthropic's promotional pricing for Claude Sonnet 5 expired this week, but the scheduled list increase was cancelled, holding the model at $21 per million input tokens and $102 per million output.

World

A US official said American forces struck two Iranian launchers on Larak Island at the mouth of the Strait of Hormuz on August 30, the first known US strike on Iran since late July and a reversal of Washington's stated week-long focus on economic pressure alone.

Markets

Mood reads Greed even as a fresh strike near Hormuz reintroduces risk premium, a combination that rarely survives contact with a second headline.

Wild Card

Three stories, one pattern: prices, launch dates and regulatory definitions are all being set provisionally, with Anthropic cancelling an increase, traders repricing GPT-6 to Q4, and officials admitting they are improvising.

Today's Focus

What else the day turns on.

01

Rulemaking Without Definitions

Officials told CNN that writing AI rules "feels like early Covid," a comparison republished August 31 that says more about process than substance. State, national and EU efforts are moving faster than any shared definition of the thing being regulated. Meta AI and other assistants are shipping into that gap, which is where enforcement risk accumulates.

02

GPT-6 Timing Repriced

Polymarket resolved its August 31 GPT-6 market at No, under 1 percent, with $1.67 million3 in volume rotating to later dates: 48 percent by September 30, 64 percent by October 31, 66 percent by December 31. That curve prices a Q4 launch, not an imminent one. It is consistent with OpenAI spending August pruning rather than shipping.

Cavya.ai

Everyone is racing to automate the translation itself; Cavya automates the boring hour before it, which is the part that actually decides whether the output reads native.

Four narrow tools, priced by the credit, that produce the prep artifacts most teams skip: a term glossary with context, a structured style guide as an editable Word file, a complexity read on the source document, and a QA pass over the finished translation. The credit model means you can test the whole set on 10 free credits before deciding, and localization managers or freelancers running multilingual projects will get real hours back. It is not a TMS, there are no integrations, and the generated glossary is a draft your native speaker still has to sign off on.

“Launch coverage frames CavyaQA as pairing AI linguistic review with standard QA checks, flagging mistranslations, awkward phrasing, inconsistent terminology, tone shifts and glossary deviations.”Slator

Code Wiki: point it at the repo nobody wants to document

Code Wiki is listed on There's An AI For That as a documentation layer for codebases, the kind of job teams defer until onboarding breaks. The directory entry is thin, so open the alternatives and pricing views before you commit a repo to it. Test it on one legacy service where the original authors have already left.

MIAPI is worth a scouting pass before you write another integration glue script

MIAPI shows up in the TAAFT index as an API-focused tool, and the listing is sparse enough that the directory page is the honest starting point rather than the marketing site. Read the alternatives view first: API tooling is a crowded category and the comparison grid will tell you faster than a demo whether this is a wrapper or a real layer. Budget 20 minutes, not a sprint.

Enjo.ai claims 20 to 80 percent of support tickets, so measure the low end

Enjo.ai is a support automation platform that says it autonomously handles 20 to 80 percent of customer and employee requests. That spread is the whole story: the outcome depends entirely on how good your knowledge base already is. Pilot it on internal IT or HR requests, where the answers are documented and a wrong reply is cheap.

AureaCam turns any phone camera into a composition coach, free and no install

AureaCam is a progressive web app that scores your live camera view from 0 to 100 against the rule of thirds and the golden ratio, with free options and nothing to download. Use it as a training wheel: shoot the same subject three ways, watch the score move, then stop looking at it. Useful for anyone shooting product photos or thumbnails without a photographer on staff.

THE DOJO · BUILD TODAY

Reprice your stack while the ceiling is still flat.

01

Rebase your cost model on list, not promo. Recalculate your per-request spend at $2 per million input and $10 per million output for Sonnet 5, then compare against the vendor-traced price index published August 30 covering 14 direct APIs.

02

Point Code Wiki at the undocumented repo. Pick the service with the worst onboarding story, generate the wiki, then read the output as a reviewer and log every place it guessed wrong. Budget 20 minutes, not a sprint.

03

Stop planning around a Q3 GPT-6. The August 31 market resolved No, so build roadmaps against the 64 percent October 31 and 66 percent December 31 lines instead of assuming a launch lands inside this quarter.

The Bottom Line

Flat prices and slipping timelines are a planning gift

Two of today's stories point the same way: the cost ceiling did not rise, and the next frontier model is being priced later rather than sooner. That combination buys builders a quarter of relative stability, which is exactly when architecture debt gets paid down instead of deferred. Regulators calling this moment "early Covid" is a reminder that the rules will arrive without settled definitions, so keep your model routing and logging swappable. Use the calm to measure real numbers, not vendor ranges.
