Quoting SpaceX S-1

We have the ability to use compute resources to support our proprietary AI applications (such as Grok 5, which is currently being trained at COLOSSUS II), while also providing access to select compute capacity to third-party customers. For example, in May 2026, we entered into Cloud Services Agreements with Anthropic PBC (“Anthropic”), an AI research and development public benefit corporation, with respect to access to compute capacity across COLOSSUS and COLOSSUS II. Pursuant to these…

Google I/O, Gemini Spark, Antigravity

It's hard to find much to write about Google I/O this year because I have a policy of not writing about anything that I can't try out myself, and a lot of the big announcements are "coming soon". I actually prefer to write about things that are in general availability, because I've had instances in the past where the previews didn't match what was released to the general public later on. Aside from Gemini 3.5 Flash the most interesting announcement looks to be Google's upcoming OpenClaw…

Release: datasette-agent-charts 0.1a1 More color! Bar and waffle charts without a color column are shaded by magnitude with a sequential color scheme; color columns holding text values use the observable10 categorical scheme. #2 Now checks execute-sql permission before running the query to find the column names. Charts now display interactive tooltips. Fixed a bug where waffleY charts were not described to the agent. Tags: datasette, datasette-agent

The following article originally appeared on the Elevate newsletter and is being reposted here with the author’s permission. Peek under the hood of most “production agents” shipping today and you won’t find intelligence. You’ll find custom plumbing, fragile session logic, shared service accounts, and a security model held together by hope. This can be so […]

Gemini 3.5 Flash: more expensive, but Google plan to use it for everything

AI Artifact Catalogs: Durable Standards Worth Institutional Investment

Companies everywhere are trying to leverage AI to boost internal productivity metrics. Some, like Ramp and Intercom, are succeeding. Many are failing. To make matters more complicated, the narrative around what tooling enables these gains is constantly shifting. For software engineers, auto-complete via GitHub Copilot was the bleeding-edge tool of choice in 2024. Then it […]

The last six months in LLMs in five minutes

The last six months in LLMs in five minutes

I put together these annotated slides from my five minute lightning talk at PyCon US 2026, using the latest iteration of my annotated presentation tool. # I presented this lightning talk at PyCon US 2026, attempting to summarize the last six months of developments in LLMs in five minutes. # Six months is a pretty convenient time period to cover, because it captures what I've been calling the November 2025 inflection point. November was a critical month in LLMs, especially for coding. # For one…
