ChatGPT Pro 500: Same Budget, Fewer Providers

Pro 500 offers 25× the Plus allowance. Optional Ultrafast consumes included usage at 8× and purchased credits at 6× Standard. Is the $700 Claude–Codex pair a better use of the trio’s budget?

Alpha School: Two Hours of AI a Day, and What It Costs

A private school network that says children learn twice as fast with two hours of AI a day. What it is, who pays for it, what it costs, what the evidence shows, and whether children outside the U.S. can attend.

ChatGPT Pro Max: The $500 Price Leaked, the Limits Didn't

OpenAI hasn't announced it, but a $500-a-month Pro Max plan has been spotted in ChatGPT's subscription screen, pitched as "Fastest Work and Codex". What the card shows, what OpenAI's own rate card already says about speed and allowances, and what to check at DevDay.

GPT-6 Sol and Luna: Cheaper Than Astra, Not Better

A fifth of Astra's price for Sol, a hundredth for Luna. My rule for the Codex seat, written before the charts: switch only to a model that beats Astra at maximum settings and costs less. Sol costs less. On every chart OpenAI published, it doesn't beat Astra.

Opus 5.5: Fable's Level at 40% of the Price

Anthropic shipped Opus 5.5 on September 22: by its own numbers, Fable 5.1's level on most work, at $4/$20 per million tokens against Fable's $10/$50, with medium as the new default effort. What the release measures, where the catch is, and how my Claude seat left Fable the same afternoon.

Grok 4.7: Same Price, Longer Runs, One 402

xAI shipped Grok 4.7 today: a larger base model, 500k context, xhigh still the ceiling, same $2/$6 price, and a few contradictions in its own pages. What the model card measures, and how every Grok pin on my desk moved to 4.7 the same afternoon, balance wall included.

The Solver Was Always the Hard Part

A year as founding principal AI-native engineer at a stealth healthcare-scheduling startup: therapy schedules for nursing facilities, OR-Tools and dynamic programming, HIPAA without the theater, Terraform on Google Cloud, and three AI agents under one rulebook. A case study.

Jev: Keep the Power. Cut the Overhead.

Jev turns natural language into choices, scores and probabilities. A practical guide to the model, the harness, the demos—and what it could change for my three-agent setup.

DeepSeek, GLM, and OpenCode

OpenCode is an open-source coding agent. DeepSeek and GLM supply models; subscriptions start at $10–$18/month with usage allowances, separate from any billed overflow.

GPT Image 2.5: Pin Sunburst

Two GPT Image 2.5 models, same token rates. Flare is the volume default. Sunburst is the precision one. Pin that when the picture is the product.

Claude Mods

Anthropic's proposed TypeScript middleware for Claude Code: how the continuation model works, the proposed API in full, worked examples, and the open questions on availability and cost.

Pace the Frontier. Name the Speed Limit.

A model can get promoted without receiving a single new weight — just a token, a runtime, and permission to spawn workers. Amodei is right that time is worth buying.

Brain Rot Is the Default Setting

AI assistance can reduce practice when it replaces the thinking a task requires. Research points to task-specific risks and ways to preserve unaided skills.

Know the Code, Write the Spec

ETH Zurich had 100 students build apps by prompt alone. Computer science knowledge predicted results best, writing skill added its own share, and frequent LLM users scored lower.

Handling AI Usage Limits and Clean Handovers

Detect provider usage limits, save verified task state, preserve stop markers and hand over cleanly without confusing account limits with model quality.

I Love Trios 😈

Three coding assistants, one desk. Same notes, same rules, same review path — and still no bake-off.

Grok Joins the Party

I added Grok Build alongside Claude Code and Codex: Grok 4.6, maximum reasoning, automatic approvals, and fixes that make the setup work.

Graph Engineering: Evidence In, Guesswork Out

How I gave my AI assistants a map of current instructions and clearer rules for when tasks can proceed — with the results explained in plain English.

Astra × Fable: Full Power, Less Waste

Astra at Ultra. Fable at max. Shared rules, native hooks and deterministic automation — configured and tested, with workload savings still to measure.

GPT-6 Astra: Priced Like a Frontier, Gated Like a Weapon

GPT-6 Astra’s access, pricing and model settings need separate checks. Compare accepted-task performance and verify availability before changing configuration.

Fable 5.1 Is In Your Max Plan. It Is Not Free.

Fable is included on Max at up to half your weekly limits. Input and output cost twice Opus 5; cache reads cost half. Whether it is cheaper per accepted task depends on workload and an efficiency claim that needs testing.
