Introducing Tool Eval Bench CLI

Hi all,
Given I regularly go through the exercise of tweaking my setup and trying out new model settings, I want a quick and easy way to understand if things have improved.

In addition to the excellent llama-benchy by @eugr which helps surface performance indicators like prefill-rate and token generation, tool calling is absolutely crucial for me โ€“ it makes or breaks an agentic coding session with Pi, Open Code, etc.

This is why I worked on Tool Eval Bench - a simple Python-based tool that goes through a set of scenarios against any OpenAI-compatible endpoint. No real API calls โ€” everything uses mock tool handlers with realistic noisy payloads, so itโ€™s fully offline and reproducible:

  • Each scenario scores 0 (fail), 1 (partial), or 2 (pass). Final score is 0โ€“100, rated from โ˜… Poor to โ˜…โ˜…โ˜…โ˜…โ˜… Excellent.
  • The full 63 scenarios cover 14 categories including tool selection, multi-step chains, error recovery, and โ€” one I care about โ€” safety and prompt injection resistance.

Using Tool Eval Bench

Itโ€™s as easy as running the following command:

uv tool install git+https://github.com/SeraphimSerapis/tool-eval-bench.git

Then start benchmarking:

# 15 scenarios for quick evaluation
tool-eval-bench --base-url http://0.0.0.0:8080 --short
# Throughput sweep
tool-eval-bench --base-url http://0.0.0.0:8080 --perf
# 3 runs of 63 deterministic scenarios
tool-eval-bench --base-url http://0.0.0.0:8080 --seed 42 --trials 3

It auto-detects your model from /v1/models. Works with vLLM, LiteLLM, llama.cpp โ€” anything that exposes the OpenAI tools API.

Results get saved to SQLite + Markdown reports, so you can track how models compare over time with --history and --diff.

Inspiration
I really like ToolCall-15, however it requires more setup and canโ€™t be run as quickly as this tool. I wanted something that requires little to no setup and can run on the CLI right away. The short scenarios (e.g., the first 15) are heavily inspired by ToolCall-15 and I want to give credit to the author.

Example Run

tool-eval-bench --base-url http://0.0.0.0:8080 --short --perf

Feedback Welcome
Iโ€™d like to hear your thoughts โ€“ is a tool like this useful for you? Do you miss anything? Do you run into any problems with it? Feel free to respond here or create an issue on GitHub. Pull requests are welcome, too!

Warm regards,

Hello @serapis ,

Looks great to me, I wonder if you test the tool loop with heavy context loaded or with clean slate context ?

For example : in the agentic scรฉnario;
You have some web_search call and I have seen the Qwn3.6-35V-A3V-FP8 fails when :

  • tasked to scrap a large web documentation
  • fail to adapt the strategy when obviously it should stop and change the approach when a dead end is met.

Overall I feel that behaviour change a lot when model is loaded with lot of context (captain obvious). So as of now the new AI frontier is orchestrator with a lot of context i have concer about performance under such env.

I struggle to find a relevant harness / agentic orchestration benchtest. Some arxiv papers try to setup such test and comparison but nothing serious. Also i wonder if someone is able to measure the โ€˜plus-valueโ€™ of the โ€˜preserve-thinkingโ€™ mode. Because Qwen 3.5 reasoning was already so verbose, you are litteraly burning token just to say hello and so performance impact negatively. Caveman skill becoming a much to have. So preserving long ass reasoning could be a weak point.

Sorry for long post.

Cheers,
William

Hey, thanks for sharing your thoughts!

Let me think about a way to fill the context before running the tool calls. I agree that this is probably a combination of harness + compaction + recovery strategy, so we may not be able to replicate the whole scenario but rather focus on assessing how the model behaves under pressure.

Super cool, going to load up a few models and cross compare. This is really helpful.

I think thatโ€™s very interesting if it can mimic real-life situations :).
The first think Iโ€™ve noticed is a problem I often see on non-random benchmarks, the context is rather small. Do you plan on generating more tests with maybe 128k context? Sending some code base as system prompt could help.
Also, I couldnโ€™t quickly find multi-turn conversations. Is that taken care of?

Yes! There is a Multi-Turn scenario and I may add more in the future.

Filling the context with a long prompt before running the suite is a great idea and Iโ€™ll try to implement it soon!

Really like this idea as well and was looking at version to install. Iโ€™ve tried a few, but think your solution has promise and maybe we should make it the default.

Agree, a large context default test would be good as well.

Interesting this one is getting higher deployability score. Is that just t/s or something else?

If this was a single Spark run, can you share your configuration and Iโ€™ll try it here as a comparison.

FYI, llama-benchy is doing exactly that (just literature, not code).

One of the things I want to try is to offer an alternative corpus with a codebase instead and see if that helps measuring MTP performance, for instance.

This is great! Are you open to branching off the tool eval and incorporating it as a part of llama-benchy?

Iโ€™ve noticed that your pp numbers are way off.

I would suggest to just use llama-benchy as a dependency for measuring throughput instead of trying to reimplement this functionality from scratch - there are a TON of things you need to take care of to measure the pp/tg numbers accurately, and even llama-benchy is not perfect yet - I have another release coming up that would make it a bit more robust in some situations.

Very open to that! I had my fair share of challenges getting the calculations right and am sure the throughput/prefill could use more love. I also tried my hand at getting more realistic benchmarks for MTP but am not there yet.

Happy to talk how we can best collaborate! Iโ€™m a massive fan of your work.

I added a first version of a context pressure mechanism to the tool:

tool-eval-bench --seed 42 --context-pressure 0.75

It tries to automatically detect the maximum context length and in this case would fill 75% with randomized text. Iโ€™ve had to tackle caching and other things, so your results may vary.

Reached out directly

This works well and is easy to extend:

Iโ€™ve done it and measured with GuideLLM and you can clearly see the benefits of turning on MTP.

v1.2.0 Release: Benchmarks via Llama Benchy

Quick heads-up: llama-benchy is now the default benchmark. This project is way more mature than my throughput methodology, so going forward, that will provide the foundation for accurate performance testing.

Updating is as easy as:

uv tool upgrade tool-eval-bench

Release notes here.

Thank you very much, thanks to the --load-format instanttensor feature; it saves 1 month a year in model loading.
