Mentis8 / os8
Durable agents that pursue goals, verify their work, remember what they learn and improve locally. Built around your firm. Running on your hardware.
An operating system for agents
os8 gives durable agents a place to act, remember and improve. The runtime and inference live on your hardware. Your custom harness connects that capability to your firm.
Work in the connected environment.
Observe what actually changed.
Keep progress. Adapt when blocked.
Goal-directed work
Agents break goals into checkable steps, act in real environments and inspect the result. When a step fails, they repair or revise the approach while preserving what already worked.
A plausible reply is not proof of a completed task.
Continuity
Agents retain useful knowledge and proven procedures across tasks. What they remember carries its source, so knowledge can be inspected rather than disappearing into a conversation history.
Local improvement
Background work consolidates memory and evaluates improvements locally. Proposed changes must pass evaluation before adoption, with rollback available. Foreground goals take priority over background learning.
Fireboard research / results
In our agent evaluations, the runtime behind os8 outperformed OpenAI and Anthropic systems using small, older-generation open-source models on a 128 GB consumer machine.
The thesis behind os8: the system around the model matters. Persistent goals, checked progress, useful memory and local learning turn model capability into sustained work.
Consumer machine.
Small open-source models.
Local execution.
This comparison concerns our simulated-company agent evaluations, including Claude Opus 5.5. Full benchmark methodology, model configurations and scores are not published here. Results are specific to the tested tasks and configuration; they do not establish superiority across all tasks or guarantee performance for an enterprise installation.
Sovereign by construction
Mentis8 has no remote backend and no access to customer data. Agent memory, local inference and learning stay on customer-owned infrastructure.
The runtime does not require a cloud service. Slack and email connect through your chosen providers; those communication channels have their own network and data paths.
People interact with durable agents through Slack and email. os8 and the custom harness provide the operating foundation on dedicated enterprise infrastructure.
The runtime grounds work in the requesting user, the connected environment and applicable constraints. Agents act incrementally, check results and retain useful experience. Your pilot establishes the enterprise connections, operating scope and acceptance criteria.
