Overview

cosmicoptima/computer-9a is a 70 billion parameter bfloat16 causal language model, representing the step-60 policy from an online terminal reinforcement-learning experiment. It was trained to interact with a bash tool via textual <tool> calls and <tool_result> observations, optimizing for automatically verified terminal tasks while regularizing against a conversational parent policy.

Key Capabilities

  • Terminal Interaction: Designed to generate and interpret bash commands within a textual interface.
  • Reinforcement Learning: Optimized through an online reinforcement learning process for terminal-based tasks.
  • Tool Use: Emits shell commands and expects external applications to parse, execute, and return results.

Limitations and Safety

This is a research checkpoint with significant limitations. It is not a generally reliable computer-use agent and may:

  • Emit destructive shell commands.
  • Hallucinate command effects or contradict visible tool traces.
  • Fail multi-stage tasks.
  • Produce terse answers.

Crucially, it should only be connected to a strongly isolated, least-privilege sandbox environment. Do not provide it with credentials, unrestricted network access, or access to valuable files. Applications must implement tool parsing and execution in a secure, isolated manner.
