🥗 Trendy Leaders, Code Reviews Reimagined, Managing Up, Rewarding Teams, Locus of Control: TMW #498

Time to abstract your AI models? What the community thinks...
🔑
This week's TMW is sponsored by Okta and Auth0 - platforms to secure all types of identity from AI agents to your customers, employees, and partners.

Hello, hello, hello, welcome to the week!

The week the community all got a bit fed up with AI models

A contentious but popular thread dominated the CTO Craft community Slack this week. It started with one member announcing they were cancelling their top tier AI subscription, worn down by talking a model out of yet another four paragraph preamble. Forty odd replies later, dozens of members had turned it into the most useful thread of the week. Nobody was writing off AI coding, quite the opposite, everyone in there uses it daily and have simply got to the point of needing abstraction... The pattern that emerged was people building themselves an exit route, so changing model is a config change rather than a migration.

Four things worth stealing

  • Treat models as commodity. Several members have moved to a neutral harness like pi.dev or opencode to avoid vendor lock in. Setup was lighter than expected, one simply asked their existing tool to configure it.
  • Route by task, not loyalty. Frontier model for reasoning and planning, cheaper tier for bulk code, heavy model saved for quant style analysis. Do it backwards and you will burn your limits in two sessions.
  • Short standing instructions beat memory. Phrases like "concise, opinionated response" outperformed any memory feature, and more than one member is thinking of switching memory off entirely.
  • Instruction drift is real. Hard rules ignored at random, with no correlation to how full the context window was. Attention was the word that kept coming up, and the thread's honest answer was a shrug.

Something to do today: Open the tool you use most and work out how long it would take to swap the model underneath it. If that is more than an afternoon, there is your side quest. Pin your prompt style into one line of standing instruction, run the same task on a second model, and see whether you miss the first one.

That's it, let's look at some links! See you next week
