we’ll converge on agentic Siri. Only distribution matters not the harness.

We’re flying in Slack, combining our in house coding agents with our @linear agent.

[Karri Saarinen @karrisaarinen]

Coinbase is also using @linear as the backbone of the operations. Their internal agent can action from there and choose the models as needed

How to keep AI spend flat while token usage grows exponentially: Not with friction and spend alerts. With better defaults, routing, and caching.

Better Defaults (not Usage Caps) – Engineers can choose any model they want, but defaults matter. We’re experimenting with defaulting to open weight models like GLM 5.2 and Kimi 2.7 through our LLM gateway, while still encouraging engineers to choose the right model for the task. 91% of our employees were never hitting their usage caps, so instead of lowering caps and driving up alerts, we're moving to cheaper defaults. Note that code reviews use a diversity of models, so they can check each other's work.

Better Routing – In our custom harnesses, we preprocess prompts and route to the best model for the job, considering cache hits and model pricing. For instance, you may want a frontier model for planning, but not for execution where they can be overkill. Ultimately, humans shouldn't be choosing models - AI can automate this task.

Better Caching – Cache misses are the easiest way to drive your cost up. All of our requests are cache aware, so we’re reusing a warm cache wherever possible. For example, our cache hit rate went from 5% → 60% in LibreChat once properly implemented.

Keep Context Lean – Start fresh sessions when switching tasks. Scope file context narrowly. Disconnect unused tools. Don't just compact. The goal isn't fewer tokens used, it's fewer tokens wasted.

Better Visibility – Our engineers can use as many tokens as they want, from whatever model they want, but we’ve made usage visible – and the more you spend on AI, the more impact we expect.

The goal isn't to suppress usage. It's to build the infrastructure that makes exponential growth sustainable.

Putting this into practice has cut our AI spend nearly in half, while our token usage continues to grow.

@brian_armstrong At @coinbase many of us have also been liking the combo Opus / GPT medium for planning and Sonnet or Cursor Composer 2.5 for execution.

[Molly O’Shea @MollySOShea]

Brian Armstrong (@brian_armstrong) on how Coinbase built one of the world's first SEC-registered AI investment advisors:

" Most people, when they write something on X, they say, 'This is not investment advice.'"

"This is investment advice. We can actually say that."
