Weave Router 2.0 matches GPT-6 Astra pass rates at ~52-54% cost on coding benchmarks
The Weave team announced Weave Router 2.0, an open-source model router that plugs into coding agents like Claude Code or Codex and switches between LLMs per task. Benchmarked against GPT-6 Astra on Terminal Bench 4.0 and SWE Atlas, the router achieved equivalent pass rates while costing ~52-54% as much and running 2.2-2.5x faster. Three improvements drove the gains: a new HMM-plus-classifier architecture, larger labeled training data, and smarter cache-eviction impact calculation.

AI Overview
- Weave Router 2.0, an open-source router for coding agents, matches GPT-6 Astra pass rates on Terminal Bench 4.0 and SWE Atlas
- Router costs 52-54% as much as Astra and runs 2.2-2.5x faster across the two benchmarks
- Router combines a hidden Markov model for session state with a classifier that narrows ~10 models per session, shrinking a 10^100-path search space
- A cache-eviction impact subsystem calculates the expected value of switching models, driving most cost savings; frontier LLMs expanded training data

Reasonary AI's Auker 1.0 rewrites its own model-allocation policy, cutting MMMU-Pro benchmark cost ~6× at unchanged accuracy
Reasonary AI released Auker 1.0, an agent that decomposes tasks and learns to allocate models, agents, tools, and reasoning across subproblems rather than routing through one fixed model. After 116 optimization experiments, its best policy scored 80.35% on MMMU-Pro at $9.73 total cost — about 6× cheaper than baseline at essentially unchanged accuracy. The company published the methodology, cost assumptions, and Pareto-frontier results, and is soliciting feedback on benchmark clarity and real-world stress tests.

Open Pstack: assigning implementation and review to different coding providers
A maintainer released Open Pstack, an MIT-licensed distribution building on Lauren Tan's Pstack and earlier ports by Michael Denyer and Eric Litman. It lets Codex or Claude Code act as parent agent while assigning implementation, review, and exploration to other providers via their own authenticated CLIs and subscriptions. The release includes provider-specific completion validation for Devin workers and notes Devin's Pro tier pricing.
