cascadeflow is slashing AI bills by routing queries through a cheap “drafter” model and escalating only when needed. It’s open-source and ready in three lines of code, with claims of 30-65% cost reductions and 70-80% of queries never touching a flagship model [1].
Cascade-Driven Cost Savings 80% of queries can be handled by cheaper models, delivering meaningful savings in production workflows [1]. The approach isn’t about grinding accuracy to zero—it’s about dialing cost until performance just fits your use case.
Cross-LLM Orchestration on a Budget Navigator is a multi-LLM control center built for about €1,000, not €500k. It connects to 500+ tools and works with any LLM—Claude, GPT, Gemini, and Llama—so you can switch between ecosystems without being locked in [2]. It’s open-source, with MCP stacks for tool connections and a distributed team shipping lean tooling that avoids heavy capex [2].
Kimi K2 Thinking Kimi K2 Thinking—Moonshot AI’s open-source thinking agent—uses a 1 trillion-parameter MoE that activates 32 billion parameters per inference. In hands-on tests it handled 200–300 tool calls coherently and supports Hugging Face integration and OpenAI-compatible APIs [5].
Finetuning on 4x GeForce RTX 3090 A 4x RTX 3090 setup is practical for finetuning tasks; renting GPUs (e.g., Runpod, Tensordock) runs roughly $0.20–$0.30/hour [4]. NVLink helps some workloads, but it’s not a universal fix; cloud training often remains cheaper for larger runs [4].
Budget-first decisions are reshaping how teams pick models and tooling. They’re widening the field beyond the usual suspects and spotlighting practical compromises over hype.
