STRIX_LLM configuration fails with BadRequestError or AuthenticationError using OpenRouter/Gemini APIs

[Mirzabaig313]

Describe the issue
Configuration and compatibility errors occur when setting up the strix-agent CLI tool locally. The errors happen when connecting to various LLM providers (OpenRouter, ZhipuAI, and Google Gemini).

The setup instructions were followed to use a dedicated virtual environment. Different connection/authentication errors are encountered depending on the configuration used.

Environment

• OS: macOS [Your OS Version]
• Python Version: 3.12.3 (via Homebrew/venv, but system default was 3.14)
• Strix Version: (Most recent version installed via pip install strix-agent)
• Installation Method: pipx initially, then isolated venv
• Docker: Docker Desktop running

Steps to Reproduce

1. Installed strix-agent in a Python 3.12 virtual environment.
2. Ensured Docker Desktop is running.
3. Attempted configuration for different providers, setting STRIX_LLM, LLM_API_KEY, and LLM_API_BASE accordingly.

Observed Behavior and Error Messages

Errors encountered:

• When using OpenRouter/Zhipu AI (glm-4.6 or x-ai/grok-4.1-fast:free): The tool returns an authentication error or provider not found error:

  # [Paste the exact litellm.BadRequestError or AuthenticationError output here]
  

• When using Google Gemini (gemini/gemini-2.5-flash): The tool returns a 404 error:

  # [Paste the exact litellm.NotFoundError output here]
  

• General Warning (Less critical): A Python 3.14 warning is consistently seen, although it does not seem to stop execution when variables are set:

  /Users/mirza/.local/pipx/venvs/strix-agent/lib/python3.14/site-packages/openai/_compat.py:48: UserWarning: Core Pydantic V1 functionality isn't compatible with Python 3.14 or greater.

Expected Behavior

Strix should connect to the configured provider using the provided API keys and begin the security assessment.

Configuration Commands Used (Example for AgentRouter):

export STRIX_LLM="x-ai/grok-4.1-fast:free"
export LLM_API_KEY="[My openRouter Key]"
export LLM_API_BASE="https://openrouter.ai/api/v1"
