Hermes-3 vs OpenClaw: latency and throughput benchmarks on InstantAgent

We ran both leading open-weight models through identical highly complex workloads across all 12 edge regions. Here are the hard numbers — and exactly when to use each one.

Choosing the right model for your specific agentic use case often comes down to a harsh tradeoff between reasoning depth, Time-To-First-Token (TTFT), and raw tokens-per-second (TPS) throughput. You cannot have all three at maximum simultaneously.

We benchmarked the two most popular models deployed on the InstantAgent network — Hermes-3 and OpenClaw 7B — to provide some empirical clarity for systems architects.

The Benchmarking Methodology

Both models were subjected to a 10,000-request suite comprised of coding tasks, multi-hop function calling, and structured JSON extraction. We measured end-to-end latency from client to our EU-West and US-East edge nodes.

The Results

OpenClaw-7Butterly dominates in latency-sensitive, rapid-fire tasks like simple code completion, basic summarization, or chat routing. It consistently delivered a blisteringly fast TTFT of < 98ms with an impressive throughput of 145 TPS. It barely utilizes 5GB of VRAM, making it exceptionally cheap to run.

Hermes-3 operates as the heavy lifter. With its massive parameter count, it exhibits a naturally longer TTFT (~240ms) and lower TPS (~60 TPS). However, its reasoning capability on highly complex multi-step planning tasks that require chained function calling was unparalleled. It scored a 92% success rate out-of-the-box on our ToolBench evaluations, absolutely crushing OpenClaw's 61% on the same rigorous tests.

The Architectural Recommendation

If your agent interfaces directly with a human user in real-time (like a support chatbot) and only needs 1 or 2 simple tools, spin up OpenClaw. If your agent is running asynchronous background data processing, handling complex refactoring tasks, or conducting deep multi-step internet research, Hermes-3 is the clear winner despite the slower token generation.
