Huzzle Labs
Commercial
medium confidence
Huzzle Labs is the applied-AI division of the London talent platform Huzzle (co-founders Ingmar Klein, CEO, and Amit Choudhary, CTO). It builds long-horizon RL environments (coding, computer use, enterprise workflows) and expert trajectory data for frontier labs, drawing on Huzzle's talent network, which it says numbers 300k+. In 2026 it expanded into its own small computer-use models (HuzzleWorld, 1B-8B, self-reported results), a domain benchmark (InsureBench, scores pending), and enterprise custom evals and models deployed on client infrastructure.

Huzzle Labs publishes HuzzleWorld, a family of small computer-use models (1B, 2B, 3B, 4B, 8B)
The vendor says HuzzleWorld is built on its proprietary architecture, its own RL environments and training from video. Self-reported results: on ScreenSpot-Pro with Zoom In, 3B scores 72.4% (66.4% single-pass), 2B 70.8% (61.7%) and 1B 63.5% (55.6%), and 3B is claimed #1 among models of 3B or smaller. On ScreenSpot-v2, 3B scores 93.4%, 2B 92.7% and 1B 91.8%. On OSWorld-Verified, 8B scores 58.6% and is claimed #1 among models of 8B or smaller. The page shows a leaderboard snapshot dated 2026-09-17 (ScreenSpot-Pro updated 2026-09-10) and says the 4B model has no leaderboard entry yet. No exact release date is given, so the month is inferred from the leaderboard dates.
Why it matters: The vendor now trains and benchmarks its own agent models on its own environments, and presents this as evidence that those environments produce model gains. No weights, license, model card or paper were found, so all results are self-reported. The vendor's pages also disagree on the 8B OSWorld rank: 11th of 41 on the model page, #13 on the enterprise and RL-environments pages.

OpenEnv Visual Memory and Spreadsheet environments on Hugging Face updated with eval runs against Claude Opus 4.6 and GPT-5.4
The huzzle-labs Hugging Face org hosts two Docker-based OpenEnv Spaces, both MIT-licensed and tagged openenv-0.2.3 and rl-environment. Visual Memory is a hidden-grid puzzle. Spreadsheet covers stateful spreadsheet editing through an API. The Spaces were created on 2026-03-18 (Visual Memory) and 2026-03-19 (Spreadsheet), and both were last modified on 2026-04-08. The Visual Memory repo includes eval outputs dated 2026-04-07 for claude-opus-4-6 and gpt-5.4, with trajectories in ATIF format as well as raw JSON.
Why it matters: These are the vendor's only open, inspectable environments. They follow the Meta-PyTorch OpenEnv spec, so they work with standard OpenEnv tooling. The first release was in March 2026, just before this window; the April 2026 update added the eval runs.

What practitioners should know
For researchers
- Open, inspectable work: two MIT-licensed OpenEnv (v0.2.3) Docker environments on Hugging Face (Visual Memory, Spreadsheet). The Visual Memory repo includes eval trajectories dated 2026-04-07 for Claude Opus 4.6 and GPT-5.4, in ATIF and raw JSON.
- HuzzleWorld computer-use models (1B-8B) have self-reported results: 72.4% on ScreenSpot-Pro (3B, Zoom In) and 58.6% on OSWorld-Verified (8B). No weights, model card, paper or license were found, and the vendor's pages disagree on the 8B OSWorld rank (11th of 41 vs #13).
- InsureBench is a GDPval-style benchmark for insurance underwriting and claims, with a public methodology page. No scores have been published yet.
For program managers
- Engagement is by email or a 15-minute Calendly call with the CEO (labs.huzzle.com).
- Frontier-lab ties: the homepage carries a testimonial attributed to Emre Guven of Meta Superintelligence Labs, and the open environments use Meta-PyTorch's OpenEnv spec. No frontier lab is publicly named or confirmed as a customer.
- Named customers (Apple, Lazard, Financial Times) appear only on the vendor's own AIX page and are self-claimed.
- Scale signals, all self-claimed: a Labs team of 15 engineers and 15 operators, a talent network of 300k+, and parent-company rankings of #7 on Sifted UK & Ireland 2026 and #14 in Europe (J.P. Morgan & Nebius 2026).
For data ops
- The vendor states AICPA SOC 2 on its site. The baseline recorded Type II from the Secureframe trust center; that was not rechecked in this run.
- The published environments are Docker-based OpenEnv Spaces serving on port 8000, each with a client.py, a models.py and a server/ directory.
- The enterprise offering says models are trained on client data and deployed on the client's own machines, and that data and models stay with the client.
- No public API docs or MCP integrations were found in this run.

How we verified this
2026-10-05 refresh: I opened every source in the draft. The core claims hold up. HuzzleWorld's model sizes and benchmark numbers match the vendor page (leaderboard as of 2026-09-17). InsureBench is built by Huzzle Labs and has no scores yet. The enterprise page describes deployment on client machines. The vendor's backers list now includes a16z Scout Fund. Hugging Face metadata confirms the two MIT-licensed OpenEnv Spaces, and their eval runs are dated 2026-04-07. The baseline blog URL returns 404. I made these corrections:
- **OpenEnv:** I fixed a creation date and reframed the item, since the first publication was in March 2026, before the window.
- **Backers:** I removed advisor and angel labels the site does not give, and restored the baseline's company-provided investor entries. I flagged that "Former CTO of Hugging Face" may not be Thomas Wolf rather than asserting it.
- **Ingmar Klein:** I removed an unsourced founding year from his background.
- **HuzzleWorld:** I added that the vendor's pages disagree on the 8B OSWorld rank.
All model results, customer names and growth rankings are self-claimed on the vendor's own pages. The Sifted page returned 403 and the J.P. Morgan/Nebius ranking was not found elsewhere. No founder headshot is available from a stable public source, so photo URLs are blank. The sweep for missed items was limited: the session's web-search budget was used up, so I could not search the open web for press coverage of a new round, acquisition or frontier-lab partnership in the window. I checked the vendor's own pages, the Hugging Face org and the GitHub org directly and found none.
