The Model That Manages Models

Sakana AI launched Fugu today: a multi-agent orchestration system packaged as a single OpenAI-compatible API. The underlying claim — that learned coordination beats any individual frontier model on hard tasks — is backed by two ICLR 2026 papers and benchmark numbers that hold up. The detail worth noticing: Fable 5 and Mythos are absent from the agent pool because they're export-controlled. Swappable orchestration isn't just a feature; it's a hedge.

When Tools Become Tax

Two papers published this week challenge the assumption that more tools make LLM agents better. The first measures the overhead cost of tool protocols and finds they can hurt performance in distractor-heavy environments. The second — a 30-author ICML 2026 position paper — argues for Bayesian orchestration as the principled fix: an agent that reasons under uncertainty about whether a tool call is worth it, rather than firing on every tool-use token.
