Releasing Apodex-1.0 Smol Models (0.8B, 2B, 4B Open-Weights) Optimized for Agentic Verification + AgentHarness Evals

Original: Releasing Apodex-1.0 Smol Models (0.8B, 2B, 4B Open-Weights) optimized for Agentic Verification + AgentHarness Evals

Apodex releases three open-weight small models specialized as verification sub-agents in long-horizon agentic pipelines, alongside the AgentHarness eval framework.

Apodex 1.0 launches with open-weight models at 0.8B, 2B, and 4B, trained not for general generation but for specialized sub-agent roles—fact-checking external claims and verifying tool call outputs before passing results to a main controller. The design targets long-horizon agent workflows where routing small tasks to lightweight models avoids wasteful use of 70B+ models at every step. AgentHarness, an open-source evaluation framework for local multi-step agent pipelines, is released alongside the weights.

The Apodex team officially released Apodex 1.0 in June 2026, simultaneously releasing three open-source small models: versions 0.8B, 2B, and 4B parameters. The design philosophy of these models is completely different from the "all-in-one large model" approach—focusing on "independent verification" capabilities in long-range tasks. These small models do not pursue omnipotent generation but serve as dedicated sub-agents at AgentOS runtime, sharing specific verification subtasks.
