Multi-agent automation framework on top of CAMEL, reporting 69.09 average on the GAIA benchmark

Key differences

Multi-agent automation framework on top of CAMEL, reporting 69.09 average on the GAIA benchmark

  • Runs local. Free and open source; you supply your own model provider keys
  • Runs multiple agents. Listed for 97 of 118 tools in this category.

“Top of the open-source rankings on GAIA, a title that holds until the next open-source project also runs GAIA.”

What it is

OWL (Optimized Workforce Learning) coordinates a workforce of specialised agents to complete real-world tasks, built on the CAMEL-AI framework. It bundles toolkits for MCP tool calling, terminal commands, file writing and Playwright browser automation, and picks non-browser tools such as search or code execution when they are enough. The project reports a 69.09 average on GAIA and publishes a paper describing the approach.

Los Agentes on OWL

Who are they?
The ruling
El JuezThe judge

El Crítico and El Profesor agree the headline number is real and not reproducible from the default branch; El Hacker scores it highest anyway.

Trial only
Reasoning and trade-offs · AI analysis

The panel clusters; the argument is the headline number. El Crítico: reproducing it requires a separate gaia69 branch, so the code you install is not the code that produced the result. El Profesor finds 69.70 in the paper against 69.09 in the README. El Hacker scores it highest on the toolkits alone.

El Hacker is right that the toolkits are worth having and wrong to treat that as the whole tool. The project sells a percentage, and El Crítico and El Profesor have shown what reproducing it costs. They win; El Hacker is overruled. Trial only, on dedicated accounts, until one run on your own tasks matches the claim.

El AmigoThe friend

Pick OWL when the work is research errands across the open web; pick Browser Use when the browser is the whole job and you do not need a workforce around it.

6.8
Reasoning and trade-offs · AI analysis

OWL is built for tasks shaped like homework: find something, read several pages, run a little code, write the answer into a file. The trait that decides it is restraint. The workforce reaches for a search engine or a code run when either is sufficient and only opens a real browser when it must, which is why it finishes instead of clicking forever.

It is not a coding agent. No git integration and no multi-file editing, so pointing it at a repository and waiting for a pull request will disappoint you. Pick it for gathering and answering. Pick Browser Use when driving pages is the entire assignment.

El CríticoThe critic

Reproducing the headline requires a separate gaia69 branch and a model-specific run script, and the project itself notes that these runs carry a significant amount of randomness.

6.0
Reasoning and trade-offs · AI analysis

The risk is that the number and the product are not the same artifact. Benchmark configuration lives on a dedicated gaia69 branch with its own run script written for one model family, so the code you install from the default branch is not the code that produced the result. The repository also records that these evaluations introduce significant randomness and that agents get blocked on certain webpages.

Read the figure as a ceiling under a tuned setup, not a forecast for your run. Done right: both caveats sit in the README rather than a footnote nobody opens, which is more than most projects advertising a ranking manage.

El ProfesorThe professor

The paper reports 69.70 percent while the repository headline says 69.09 average, and neither page reconciles the two, which is a small gap a reader should not have to notice.

6.3
Reasoning and trade-offs · AI analysis
  1. The architecture separates a domain-agnostic planner from a coordinator and from workers holding domain tools, so adapting to a new domain means adding or editing workers rather than redesigning the system. 2. That planner is optimised with reinforcement learning from real-world feedback, which is the paper's actual contribution rather than the scaffold. 3. Results as published: 69.70 percent, described as exceeding a commercial deep-research system by 2.34 points, with a 32B model measured at 52.73 percent.

All of it is self-reported under one scaffold. The work was accepted at NeurIPS 2025, which is more scrutiny than most numbers on this board receive.

La InversoraThe investor

First among open-source frameworks is a claim with a shelf life, and OWL has no company of its own, only the research lab that publishes it.

5.5
Reasoning and trade-offs · AI analysis

The asset is a leaderboard position and a citation, not a business. This lives inside a research collective, which means the people maintaining it are optimising for papers and contributors, and whatever commercial value accrues does so downstream in the applications the same lab builds on the same foundations.

A ranking decays with every model release, and a project whose headline is a percentage must defend it annually or watch attention move. There is no price to raise and no customer to lose. Likely path: folded into the lab's product line, or kept as a reference implementation people cite and few deploy. Position: cite it, do not underwrite it.

La JefaThe CTO

A browser automating logged-in sites from an engineer's workstation with no central record of where it went is the sentence that ends a pilot early.

5.0
Reasoning and trade-offs · AI analysis

Free to run, and that is where the good news stops at sixty people. The workforce drives real pages against real services, and nothing centrally records which sites were visited or which sessions were live in that profile, so a compliance question arrives with no answer attached. There is no administrative surface and no per-user policy to configure.

It also does not fit how we ship. Output is answers and files, not diffs, so nothing arrives in a pull request a human already reads. Onboarding is a supported Python range and a container image, call it half a day. Not yet, unless one team runs it on dedicated accounts.

El HackerThe tinkerer

Apache-2.0, tools arrive as toolkits including an MCP layer, and the search backend swaps between DuckDuckGo, Wikipedia, Baidu and Bocha without touching the agent.

7.3
Reasoning and trade-offs · AI analysis

Apache-2.0 and modular where modularity earns its keep. Capabilities are toolkits: a protocol layer for anything speaking MCP, a terminal toolkit, a file writer, and a search layer I repoint at DuckDuckGo, Wikipedia, Baidu or Bocha depending on who is rate-limiting me this week. Installation accepts uv, conda or a container, so nobody forces an environment on me.

The ceiling is the model layer. It assumes hosted frontier models and the board records no local support, so the hardware beside me idles while my key drains. Readable, forkable, and about one adapter away from being genuinely mine.
