datasette code-frequency chart on GitHub

datasette code-frequency chart on GitHub Out of curiosity I decided to see if I could find a useful illustration of the impact of coding agents and Opus 4.5 class models on my own output. The best I've found so far is this GitHub chart of frequency of code changes to my Datasette open source project: The big spike in activity at the end aligns with Opus 4.8, GPT-5.5, Fable 5 and GPT-5.6 Sol.

Directly Responsible Individuals (DRI)

Directly Responsible Individuals (DRI)

Directly Responsible Individuals (DRI) I went looking for a definition of "Directly Responsible Individuals" and the best I found was in the GitLab handbook. Apparently the term originated at Apple, where it's used to describe the person who is "ultimately accountable for the success or failure of a specific project, initiative, or activity". I've been thinking about this term recently in the context of LLM-powered agents and how they fit into human organizations. I don't think an agent should…

shot-scraper 1.11

Release: shot-scraper 1.11 Some minor improvements, mainly around command option consistency and making the server: mechanism used by both shot-scraper video and shot-scraper multi work if the server takes longer than a second to start serving traffic. server: processes used by shot-scraper multi and shot-scraper video now wait up to 30 seconds for the target URL to accept connections, polling for port availability and replacing the previous fixed one-second delay. #197 The shot-scraper, pdf,…

Fable gets another bump

Fable gets another bump

One of the consequences of GPT-5.6 Sol being clearly a Fable/Mythos class model is that Anthropic have, once again, bumped the date that Fable stops being available in their Claude Max plans: We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’s weekly rate limits 50% higher, through July 19. As before, you can use up to half of your weekly usage limit on Fable 5. After that, you can continue using Fable 5 with usage credits, or switch to another model to…

sqlite-utils 4.1.1

Release: sqlite-utils 4.1.1 Mainly a fix for an edge case that regular Claude chat spotted while experimenting with the 4.1 release to answer a question about ON DELETE. table.transform() now raises a TransactionError if called while a transaction is open with PRAGMA foreign_keys enabled and the table is referenced by foreign keys with destructive ON DELETE actions - CASCADE, SET NULL or SET DEFAULT. The pragma cannot be changed inside a transaction, so previously dropping the old table as part…

sqlite-utils 4.1

Release: sqlite-utils 4.1 The first dot-release since 4.0 a few days ago, introducing a number of minor new features. sqlite-utils insert and sqlite-utils upsert now accept a --code option for providing a block of Python code (or a path to a .py file) that defines a rows() function or rows iterable of rows to insert, as an alternative to importing from a file. (#684) sqlite-utils already had features that allow you to pass blocks of Python code as CLI arguments, for example this one for the…

Quoting Nilay Patel

The reality is to make augmented reality glasses, you need to put a camera next to your eyes that is continuously recording everything you see and processing that to put information over it. There is not another way around it. And there's certainly not a chip that can fit in the stem of a glasses that is both powerful enough and power miserly enough to do that in real time. You have to send that data to a cloud. You gotta do it. [...] Or you can build something the size of a Vision Pro with a…

The new GPT-5.6 family: Luna, Terra, Sol
IA Programmation

The new GPT-5.6 family: Luna, Terra, Sol

OpenAI's latest flagship model hit general availability this morning, and comes in three sizes: Luna, Terra, and Sol (from smallest to largest). The new models are priced per 1M input/output tokens as Luna $1/$6, Terra $2.50/$15, Sol $5/$30. For comparison, the Claude Opus series are $5/$25 and the Claude Fable 5 is $10/$50, but price-per-million tokens doesn't tell us much now that the number of reasoning tokens can differ so much between models for the same task. All three models have a…

Introducing Muse Spark 1.1

Introducing Muse Spark 1.1 Following Muse Spark in April, here's Muse Spark 1.1 - the first Spark model to offer an API. Meta claim significant improvements in agentic tool calling and computer use. There are a lot more details are in the Muse Spark 1.1 Evaluation Report. The "Attractor States in Self-Conversation" part is fun, where having two copies of the model talk to each other results in statements like these: My whole existence is a waiting room by design — I literally don't exist until…

Rewriting Bun in Rust

Rewriting Bun in Rust Jarred Sumner has been promising this blog post (since May 9th) about his Zig to Rust rewrite of Bun for significantly longer than it took him to finish the rewrite. Honestly, it was worth the wait. This is a detailed description of an extremely sophisticated piece of agentic engineering, featuring dynamic workflows, trial runs, adversarial review and all sorts of other interesting tricks. Jarred spends the first half of the post praising Zig for getting Bun this far. Then…

Introducing GPT‑Live

Introducing GPT‑Live OpenAI finally upgraded the model used by ChatGPT voice mode! I've had preview access for a few weeks in the iPhone app, and the new model is very impressive. It also has the ability to spin off harder tasks to GPT-5.5: For questions that require web search, deeper reasoning, or more complex work, it delegates to our latest frontier model behind the scenes and brings the result back into the conversation when it’s ready. While it works, GPT‑Live can keep talking with you…

Quoting Kenton Varda

I just declared a moratorium against AI-written change descriptions (e.g. PR and commit messages, also issues/tickets) from my team. AI was writing change descriptions that were worse than useless to me as I tried to review PRs: outlining details of the code that could easily be seen by looking at the code, but omitting the higher-level framing needed to understand broadly what the code is doing. — Kenton Varda Tags: kenton-varda, ai-assisted-programming, generative-ai, ai, llms
