AI Summary

Updates the default model to GPT-5-mini, introduces empirical validation tools and Jupyter widgets, and adds cost tracking and experimental Ollama support.

Key Highlights

Default model changed to GPT-5-mini (requires config adjustment)
New `SimulationExperimentEmpiricalValidator` for statistical validation
Interactive `AgentChatJupyterWidget` for notebook conversations
New cost tracking utilities at client, environment, and agent levels
Experimental Ollama support for local models

Breaking Changes

GPT-5 model series uses different parameters than the former GPT-4* series, so you may need to adjust your config.ini settings accordingly.

New Features

SimulationExperimentEmpiricalValidator
AgentChatJupyterWidget
Cost tracking utilities
Ollama support
Example notebooks demonstrating empirical validation

Full Release Notes

**[2026-02-01] Release 0.6.0 with new features and model updates:**
  - Default model is now `gpt-5-mini`. **Important:** The GPT-5 model series uses different parameters than the former GPT-4* series, so you may need to adjust your `config.ini` settings accordingly. Legacy models (`gpt-4.1-mini`, `gpt-4o-mini`) are still supported.
  - Introduces `SimulationExperimentEmpiricalValidator` to compare simulation results against real-world empirical data using statistical tests (t-test, KS-test). This is essential for validating that simulations match actual human behavior.
  - Introduces `AgentChatJupyterWidget` for interactive conversations with agents directly in Jupyter notebooks.
  - New cost tracking utilities at client, environment, and agent levels to monitor API expenses.
  - Adds experimental/limited Ollama support for local models. See [Ollama Support](./docs/guides/ollama.md) for details.
  - New example notebooks demonstrating empirical validation against real survey data.
  
  **Note: GPT-5 model parameters differ from GPT-4*, so please retest your important scenarios and adjust configurations accordingly.**
