OpenAI and Anthropic cut their LLM prices by up to 80% within a few months. Why?

Max Woolf

Everyone building on these APIs has noticed the bills falling and quietly assumed it was loss-leader pricing with a reckoning attached; Woolf lines up the actual cuts — Luna down 80% in July, Sol halved in September, Opus 5.5 landing 40–60% under Opus 5 — and argues the reckoning theory does not survive contact with the substitutes. The mechanism worth internalizing is the cache read: it is 96–99% of agentic coding spend, which means Fable 5.1's 75% cache-read cut was effectively a 70–75% price cut on the only line item that matters, and it explains why the labs keep discounting the cheap-looking number instead of the headline one. Vercel's gateway data has cost per token at 43% of April's level while aggregate spend climbs anyway, which is the shape of a market where demand outruns deflation. He is honest about the part he cannot explain — the losses, the IPOs, the reported 80% per-token margins — and the useful conclusion is narrower than the headline: price increases look unlikely while OpenRouter makes switching a config change, but the subscription allowances are where the squeeze actually shows up first.

AI & Agents

Drew Breunig

The State of Context Engineering

Breunig's taxonomy of context failures has been the useful one for two years, and this update adds the two that only show up once a model is driving its own harness for hours: fighting the weights, where a model resists instructions that contradict its training, and context inertia, where it locks onto a hypothesis and keeps spending turns on it. His framing of the shift from prompt to context to harness engineering names what anyone running long agent sessions has been doing by feel, and the operating advice is concrete — around 200k tokens is a reasonable reset point, and Anthropic's Memento clears context roughly every 90 minutes and keeps a written note instead. Strategic forgetting as a design requirement rather than a failure is the idea to steal.

A 10-year-old CNN outperforms frontier LLMs for skin cancer diagnosis

A dermatologist put GPT-6 Astra and Fable 5.1 against an Inception v3 fine-tuned on 68,000 archive images, across 200 biopsy-confirmed lesions, and the 2015 architecture got 62% of first-choice diagnoses to the models' 42%. The error pattern is the finding, not the score: each LLM had a favourite answer it reached for under uncertainty — Astra called 75 lesions basal cell carcinoma, Claude called 53 actinic keratosis — and the gap was widest on the benign cases, where saying nothing is wrong is the whole job. Worth reading next to the price piece above, because the thing that got cheap is general capability, and this is a clean demonstration that general capability is not what every task was waiting for.

Engineering & Leadership

Sage Lazzaro, LeadDev

Engineers are coding out loud

Voice coding arrived through accessibility — RSI, Tavis Rudd's 2013 setup — and is being adopted now for speed, which is the usual route a practice takes into the mainstream. The honest reporting here is in the limits: the engineers using it most say it works for long, well-formed instructions and not for thinking, because speaking removes the pause typing gives you, and the real barrier is not transcription accuracy but that nobody wants to narrate code to their phone on a crowded street. The leadership question underneath is one nobody is asking out loud yet, which is what a team norm looks like when half the input method is audible.

Overgrown, when plants invade your abandoned tabs

A Chrome extension that runs a neglect clock on every hidden tab and slowly grows SVG vines across it; past 5% coverage the page stops accepting clicks, and you clear it by dragging a machete, chainsaw or flamethrower through the foliage. The build is the ordinary three-part extension — background worker, popup, content script — which is the point: the delight is entirely in the premise, not the stack. Gerard says it will not make her read her tabs and that this is fine, and the honest accounting is that 14 of her 22 tabs were already fully overgrown.

Cloudflare

How Commerce.com and Cloudflare are getting storefronts ready for AI agents

WebMCP lets a page hand an agent real tools — search_products, add_to_cart — instead of making it guess at the DOM, and Cloudflare injects the script at the edge so site owners ship no code. The interesting part is the multi-tenancy problem: Commerce.com runs nearly 100,000 domains on one zone and WebMCP shipped as a single zone-wide switch, so they built per-merchant opt-out through a Configuration Rule reading custom hostname metadata, plus a zone setting for a non-default MCP path. If you host other people's sites on Cloudflare, that pattern — a zone-level feature made per-tenant with a rule evaluated before the page is served — is the transferable bit. Checkout stays a human click.

A post-grad's guide to the best chocolate chip cookies on the Upper West Side

Five cookies in walking distance, reviewed by someone who deliberately excluded the chains and anything already carrying viral weight, and graded partly on whether the thing survives being carried home in a bag — the correct criterion and the one no national list applies. Mast Market on Columbus takes it on sea salt and a cakey-gooey middle; La Farine's is the most expensive at $6.95 and so soft it disintegrates on removal; Silver Moon's is the dry crumbly outlier, closer to Tate's, which is either a flaw or the point depending on your household. Useful as a baker's control group: five versions of the same formula within twenty blocks, and the differences are all texture decisions.

Luke Plunkett, Aftermath

A Little Age is a neat little game about building tiny towns

A ten-dollar isometric settlement builder where each hamlet is its own closed economy: grow one into a village, found the next, and eventually point all of them at a single civilization-defining temple. Plunkett's verdict is that the only real strategic decision is where to put each hamlet and that this is fine, because the game is a single relaxed evening rather than a months-long commitment — and the demo contains most of it. The units build their own roads, which is the detail that will get you.

Was this the exact date of Van Gogh's Starry Night?

The sky in Starry Night has been treated as invention for a century, but a team at Kyung Hee University ran shape analysis on the five central stars and got the Hyades in Taurus rather than the Aries an art historian proposed in the 1980s — and the Hyades, a low Venus and a crescent moon only lined up that way before dawn on July 22, 1889. The crescent is the tell: the old June date required a waning gibbous, which is not what is on the canvas. Then it gets strange, because the obvious objection is that a seizure had left Van Gogh unable to paint in mid-July, so the authors go to his letters, find he said the seizure struck while painting on a windy day, pull the 1889 weather records for Saint-Rémy, and show the mistral did not arrive until the 27th. They also count the days over 86°F in each month, because he complained about cicadas, and July had eighteen to June's four.

Ice Age Europeans were more connected than we thought

The oldest complete genome yet recovered from southwestern France belongs to a Gravettian woman from Isturitz Cave, and most of her ancestry is western European with a clear seam of central and eastern material running through it. The modelling puts a pulse of gene flow travelling east to west around 32,000 years ago, which collapses the tidy two-population picture of Gravettian Europe — the mammoth-ivory figurine people were not two isolated groups but something with traffic between them. The authors float Isturitz as a meeting place, which is a lot of inference from one skeleton, but a second individual from Ormesson points the same direction.

Premier League: 10 talking points from the weekend's action

The Chelsea entry is the one to read and it is not about Saturday's 2-0: João Pedro scanned on Sunday and is expected to miss Liverpool and Manchester United at minimum, Emegha has not played since arriving from Strasbourg, and Alonso left Welbeck on the bench anyway. Steinberg's arithmetic is brutal — two league games without João Pedro this season, two defeats, no goals in either — and it reframes selling Nicolas Jackson to Villa, who scored against Manchester City this weekend. Elsewhere: Bournemouth's three scorers cost £85m combined and put three past Manchester United, whose own week ends in board-level crisis talks.

Mbappé double secures Real Madrid late victory at Barcelona after Raphinha leveller

The paper teed this up on Saturday as Mourinho's return to the Camp Nou thirteen years on, and it delivered the ending he builds teams for: Bellingham to Camavinga, Camavinga past Cubarsí, Mbappé finishing in the 87th. The tactical fact is the one to keep — Barcelona had been running at 4.3 goals a game and Madrid held them to one, which is the first time Barcelona have failed to win anything since returning to the stadium a year ago. A nine-point gap and a title race finished before November, unfinished.

Yaxel Lendeborg is delivering hope even as the Warriors stumble

Three games in, the 11th pick is averaging 18.7 points, 8.3 rebounds and 4.3 assists on 34 minutes a night and hitting 44% from three, and Hardee's point is that none of it is garbage time — Kerr is playing him in close games because the roster needs it. The useful contrast is with Wiseman in 2020, handed the same trial by fire at 19 with three college games behind him; Lendeborg is 24 and arrived via a warehouse job, junior college, UAB and Michigan, which is five years of figuring out who he is. The franchise has spent a decade talking about the future as the thing it discusses while Steph handles the present, and this is the first week that has run the other way.

Free Late-Night Wednesday at the Museum of the City of New York

Museum of the City of New York, 1220 Fifth Ave at 103rd St

The museum stays open late on Wednesdays and admission is free until nine; this week the evening is dressed as a thank-you to the city's first responders, and the ice cream and the Mount Sinai occupational-health tables are for them. What is for everyone is the rest of it: the galleries after dark, a cash bar with one cocktail on it, and a docent named Harriet running a trivia-and-prizes tour of New York at Its Core at 6:30. A permanent exhibit about four centuries of a city is a different object at night with a drink in your hand than it is on a Saturday with strollers.

The Harder They Come, introduced by Ashley Clark

Film Forum, 209 W Houston St, West Village

Perry Henzell's 1972 Kingston film, the one whose soundtrack did more to export reggae than any record label managed, with Jimmy Cliff playing a country singer ground down by crooked police and crookeder producers. Ashley Clark introduces, which is the reason to pick this screening over watching it at home. Eighteen dollars, twelve for members, 109 minutes.

Responsible Tech Summit: Principles to Power

The Times Center, 242 W 41st St, Midtown

All Tech Is Human's annual day on the unglamorous half of AI work — turning evaluations into standards somebody can actually enforce, and what oversight looks like once the voluntary-commitment era ends. GitHub's CISO, Microsoft's responsible-AI policy lead, Rumman Chowdhury and Cathy O'Neil, plus Assembly Member Alex Bores, who writes the state bills that will land on his industry first. A hundred and fifty dollars for one of about 375 seats, and free on the livestream if the room is not the point.

Metrograph, 7 Ludlow St, Lower East Side

Akerman films 1976 New York in long static takes while reading aloud her mother's letters from Brussels, and the traffic keeps drowning them out. It is the best film anyone has made about what a city sounds like when you are not from it, paired with a subway short and introduced by series curator Genevieve Yue.

Quote of the day

“It won't necessarily make me read my tabs more but it's ok.”

— Charlie Gerard, on the browser extension she built to grow vines over them

On this day

October 26, 1825 — the Erie Canal opens, and a cannon relay carries the news from Buffalo to New York Harbor faster than any boat could. Governor Clinton pours a keg of Lake Erie into the Atlantic, and a 363-mile ditch quietly settles the question of which American port city would matter most. The canal is the infrastructure; the cannons were the status page.
