A 35B 'co-work' model lands at the cheap end of a cost-performance curve, its authors report

A preprint describes Occamy-1.0, a 35-billion-parameter agent model built by further training an existing checkpoint, and reports it is competitive with larger systems on the authors' own benchmarks. The claims rest on the team's stated evaluation and pricing protocol, not independent testing.

Occamy-1.0 is aimed at 'co-work' agents — systems that gather information, call tools, write code and move files across many model invocations, where cost and latency accumulate over a whole episode. The authors built execution-grounded data and environments, captured replayable long-horizon trajectories, and used staged post-training on the post-trained Qwen3.6-35B-A3B checkpoint. Across a suite of co-work benchmarks, they report it is consistently among the strongest comparably sized models and competitive with substantially larger frontier systems on several tasks. Supporting evaluations in tool calling, coding and instruction following are said to preserve broad agentic capability. The model weights and a subset of the training data are released.

Stated by arXiv

Occamy-1.0 is a cost-efficient co-work model obtained by further training the post-trained Qwen3.6-35B-A3B checkpoint.
The authors release the model weights and a subset of the training data to support research on practical co-work agents and agentic post-training.
Under the authors' stated evaluation and pricing protocol, aggregate performance across four representative benchmarks places the model at the low-cost knee of the observed cost-performance Pareto frontier.
The authors report that supporting evaluations in tool calling, coding, and instruction following show the specialization preserves broad agentic capability.

Our view

The headline numbers come from the authors' own protocol, so the durable contribution here is the released weights and training-data subset rather than the ranking.

What the reporting says: Under its stated evaluation and pricing protocol, Occamy-1.0's aggregate performance across four representative benchmarks places it at the low-cost knee of the observed cost-performance Pareto frontier.

How this story was checked

This story was written from the 1 page listed above, read by the collector on 14 September 2026 and stored.
Each line under What the reporting says was checked against that stored text on 14 September 2026. The check reads the stored text; no claim rests on a fresh look that did not happen.
Of 4 reported statements recorded for this story, 4 were confirmed against the page that carries them and are shown above; 0 could not be confirmed and were removed rather than published.
Some of the source text is the publisher's own feed summary rather than the full page, and the sending desk says so where it matters.
Figures in the text were required to appear in the stored source text before publication: yes. Identifiers: yes.
Where the reporting was silent, the text says so instead of filling the gap.
