500x Engineer

DESCRIPTION:

Thomas Dohmke, GitHub's former CEO, just launched Entire: a Git forge built for coding agents that wants to replace the pull request with Trails. I walk through why the PR became the bottleneck, what Trails and Continuous Memory actually do, the math behind the "89x faster than GitHub" claim (and its footnotes), what it costs, and two ideas for getting paid with review agents.

Figures are as published on October 27, 2026. Entire's speed and token numbers (89x, 6x, 71%) are Entire's own claims, measured with its own tools; I did not run a benchmark of my own. The "getting paid" section is my opinion, not a promise of income.

DESCRIPTION:

OpenAI just dropped GPT-6.1 Terra: half the price of GPT-6.1 Sol on every line of the price sheet. Is it half as good? I put OpenAI's own claims next to independent numbers from Artificial Analysis, walk through the five catches (including a price cliff at 272K input tokens), do the cost math per task, and finish with who should use it and two ways to get paid with it.

Prices and scores are as published on October 27, 2026. Benchmark figures labeled "OpenAI" are first-party claims; independent figures are from Artificial Analysis. I did not run a test of my own. The "get paid" section is my opinion, not a promise of income.
