I was building agentic workflows at work and got curious about how expensive each run actually is, so I built this.

We were building agentic workflows, and I started noticing how many tool calls a single run could involve. A seemingly simple task could trigger multiple LLM calls, tool executions, and repeated context being sent back and forth. The costs add up quickly and i thought can we make agents significantly cheaper without sacrificing reliability? So I built Obol, an experimental framework to benchmark different execution strategies for tool-using AI agents. GitHub: https://github.com/Aparaji

AI 分析

痛点:AI agent 一次运行会产生多次 LLM 调用与重复上下文,token 成本快速累积,却难以在降本的同时保证可靠性。

目标用户:构建 tool-using AI agent 的 AI 应用开发者、工程团队与推理成本优化负责人

证据:Plan-once was 20–60x cheaper in my experiments, but could silently produce incorrect answers. / Repeatedly sending conversation history contributes significantly to token costs. / can we make agents significantly cheaper without sacrificing reliability?

变现:开源框架加托管 SaaS:按 trace 量或月订阅收费的 agent 运行成本分析与执行策略优化服务;企业版私有部署与团队报表。

MVP:两周内做一个 agent trace 成本分析器:包一层 OpenAI/Anthropic SDK,记录每次运行的 token、成本与工具调用链,自动标出重复上下文浪费,并给出 plan-once 改写建议与成本对比报表。

竞品:LangSmith、Langfuse、Helicone、AgentOps、Braintrust

摘要:作者用实验框架 Obol 对比 ReAct、plan-once、cheap-first cascade 等 agent 执行策略的成本,发现 plan-once 在其实验中便宜 20–60 倍,但可能静默产生错误答案;重复发送对话历史是 token 成本的主要来源,cheap-first 未达预期标准。项目仍处实验阶段,作者只求 star 和反馈,全文没有付费意愿或收入数据。
