Apodex 1.1: Scaling Agentic Intelligence for Complex Work
Abstract
General-purpose language models can reason and synthesize knowledge, but complex work also requires sustained interaction with files, information sources, and executable code, together with state maintenance, failure recovery, and verifiable delivery. We call this working capability: sustained, verifiable progress toward a real-world objective. Apodex 1.1 develops this capability along two complementary dimensions. Environment Scaling expands the diversity and verifiability of executable file, search, and code environments, while Agentic Coordination Scaling trains agents to decompose long-horizon tasks, delegate parallel work, integrate asynchronous results, and replan. A shared execution harness and AgentOS maintain task state and provenance across tools and agents, and training turns environment trajectories and coordination traces into reliable behavior. Across complex professional work, finance, scientific research, mathematics, coding, and search, Apodex 1.1 reaches the leading performance band despite using a substantially smaller model than many frontier systems. The 35B-parameter Apodex 1.1 Mini further retains strong working capability in a locally deployable form. These results ground agentic intelligence in useful, verifiable work completed over time and advance our goal of building a Heavy-Duty Solver for ambitious, long-running tasks.

| Family | Construction | Verification boundary | Role |
| File worlds | Profession-conditioned multi-format workspaces | Code-derived values or recorded provenance | Authority and transformation |
| Search worlds | Indexed or open evidence sources | Provenance + claim review | Discovery and evidence alignment |
| Code worlds | Repositories and stateful sandboxes | Tests + artifact checks | Executable transformation |
| Concern | Failure mode | Mechanism |
| Workspace state | Ambiguous ownership or backend-dependent visibility | Stable three-region namespace with explicit private/shared workspace topology |
| Reference library | Durable user documents exposed to mutation | Read-only /shares mount, configured by the deployment |
| Coordination state | Plan and completion state disappear during compaction | External task board, periodic re-injection, and finalization gate |
| Live intervention | A follow-up waits behind a long fan-in operation or races a report | Message-addressable queue, interruptible waits, delivery acknowledgement, and lease renewal |
| Context pressure | Estimate-driven compaction fires too early or too late | Provider-reported trigger, tool-result eviction, and conditional LLM summary |
| Budget enforcement | Hard cancellation discards work in flight | Shared soft/hard budget, deadline-clamped waits, and bounded report recovery |
