OpenSquilla routes turns to cheapest capable model
OpenSquilla is an open-source agent framework that places a small on-device classifier, SquillaRouter, in front of larger models to route each conversational turn to the cheapest model able to handle it. The project frames itself as a "token-efficient, microkernel AI agent" with a single turn loop that supports many input channels (chat UIs, CLI) and a pluggable provider layer that can call dozens of LLM vendors. SquillaRouter runs locally using ONNX Runtime and LightGBM; routing is optional (fallback to single-model routing exists). The project ships preview releases (current at 0.5.0 Preview 4) and publishes a technical report claiming a harness-native router can convert agent traffic into a self-improving training signal.
Introduces an on-device routing approach that could reduce per-turn LLM costs and enable a harness-native training signal, but it is a preview open-source project rather than a major platform update.

Key Takeaways & Evidence Grounding
- OpenSquilla routes each conversational turn to the cheapest model that can handle it using a local classifier called SquillaRouter.
- SquillaRouter ships as on-device model assets and runs on ONNX Runtime and LightGBM with NumPy and tokenizers.
- The framework exposes a single shared turn loop across many entry points (Web UI, CLI, chat channels) and supports numerous chat providers (Feishu, Telegram, DingTalk, QQ, WeCom, Slack, Discord; Matrix optional).
- A pluggable provider layer allows OpenSquilla to call many LLM providers including TokenRhythm, OpenRouter, OpenAI, Anthropic, Ollama, and DeepSeek without changing code or config schema.
- The project is in preview (version 0.5.0 Preview 4) and ships a technical report titled "Agentic Routing: The Harness-Native Data Flywheel" arguing agent traffic can serve as training data for the router.

Production AI Agent for $5/month with OpenRouter
A developer describes a six‑month effort to build and deploy production-grade AI agents for under $5/month by combining open-source LLMs with OpenRouter (an API aggregator). The article outlines architecture choices—LangChain/LlamaIndex for orchestration, OpenRouter to route requests and fallbacks across models (Mistral 7B, Meta Llama 2 70B, NousResearch Hermes 2 Pro)—and provides code examples for a ReAct agent, environment setup, and a simple monitoring/cost-logging wrapper. The author lists per-token cost examples for several open-source models, notes OpenRouter’s $5 free credits for testing, and offers practical guidance for persistence, monitoring, and A/B testing models in production.
Nvidia Open-Sources Switchyard Router for Agents
Nvidia released Nemotron 3.5 Lightning, a 30B open mixture-of-experts model with 3B active parameters, alongside NeMo Switchyard, an open-source router that routes steps of agent workflows between models. Switchyard is presented as a provider-agnostic SDK with both tuning-free and tunable routing algorithms, letting developers define model pools and tune routing for quality, latency, and cost. Vendor benchmarks cited include LangChain reporting a 74% cost reduction across 145 multi-turn tasks (with 7% of calls going to the frontier model and a 6% accuracy tradeoff) and Ramp reporting parity on an internal SWE-Bench while cutting costs 58% and runtime 33%. The article frames the router as infrastructure for per-step decisioning, logging, evals, and escalation rules rather than a simple cost cutter.
Tiered Model Routing Cuts Claude API Costs
A developer-author describes a four-tier model-routing architecture to reduce costly use of Anthropic’s Claude Sonnet in autonomous Claude Code agents. The system routes tasks to the cheapest capable model: Tier 0 uses local Ollama inference (qwen2.5:7b) for classification, extraction and summarization; Tier 1 uses Claude Haiku for reliable structured outputs; Tier 2 reserves Claude Sonnet for multi-step reasoning, code, and synthesis; Tier 3 uses Claude Opus only for irreversible, highest-stakes actions. The article includes a decision tree, example routing code, Ollama setup steps, instrumentation advice, and a day-in-the-life cost comparison showing roughly a 95% reduction in API token usage for background tasks. The author packages the routing configuration as a skill on ClawMart.
