Model-router docs, pricing signals, gateway projects, and cost-aware routing approaches for choosing the right model per task.
Searchers want cheaper or smarter ways to route prompts across model providers without giving up too much quality.
Routing turns tokenmaxxing from a spending contest into an allocation problem: which model is good enough for this exact step?
Pricing pages, context-window changes, gateway projects, public router usage, and practical notes on fallback and retry behavior.
OpenRouter's public app/agent leaderboard briefly put Hermes Agent at #1, illustrating how token-based usage dashboards can steer attention in the agent boom.
Fresh AI infra angle on why token volume becomes dangerous when teams optimize for consumption instead of attributable outcomes.
Anthropic ties higher Claude Code and API limits to new compute capacity, making capacity itself part of the agent-product story.
Augment Code introduces Prism, a cache-aware model router for coding-agent sessions that chooses an underlying model per user turn to reduce token spend without materially degrading output quality (per Augment’s benchmarks).
Official Prism launch note on per-turn model routing for coding work, framed around cost control without forcing teams onto one model family.
Public model metadata, download counts, likes, and tags can support an open-model momentum board.
The source behind the leaderboard: model IDs, pricing fields, context length, supported parameters, and update feeds.
