Interesting Look
Bear in mind Feldman is hardly a neutral observer — Cerebras is the inference vendor being name-checked, so this reads as customer marketing with a technical wrapper. Still, the pattern he flags is real and telling: production agents are converging on hybrid stacks where latency-critical calls go to fast open-weight inference while tool access sits behind tight permissioning.… more
That split between frontier APIs and specialized silicon looks like a durable design choice, not a one-off deployment quirk. For those of you building agents, the guardrail-plus-routing architecture is the part worth studying; the enthusiasm about the vendor can be discounted accordingly.
Interesting look under the hood of @AlphaSenseInc's SuperAnalyst.
Lots of thoughtful engineering in how they give agents the tools to do useful research while keeping access tightly controlled.
And when speed matters, they route requests to open-weight models on Cerebras.
Worth a read if you’re building agents:
