 # itp-interface
-Generic interface for hooking up to any Interactive Theorem Prover (ITP) and collecting data for training ML models for AI in formal theorem proving. 
+Generic interface for hooking up to any Interactive Theorem Prover (ITP) and collecting data for training ML models for AI in formal theorem proving.
+
+## 🎉 What's New
+
+**Python 3.14 Free-Threading Support** (January 2025) - `itp-interface` now supports Python 3.14's experimental free-threading mode (GIL-free execution)! Experience true parallel proof search with up to 2.13x speedup on multi-core systems. The interface automatically detects your Python version and seamlessly falls back to thread-based parallelism when Ray is unavailable. See [Python 3.14 Free-Threading Support](#python-314-free-threading-support-optional) for details. 
 
 ## Quick Setup for Lean 4:
 1. Install itp-interface using the following command:
 ```bash
 pip install itp-interface
 ```
 
-2. Run the following command to prepare the REPL for Lean 4. The default version is 4.7.0-rc2. You can change the version by setting the `LEAN_VERSION` environment variable. If no version is set, then 4.7.0-rc2 is used. However, the itp-interface supports up to Lean 4.17.0.
+2. Run the following command to prepare the REPL for Lean 4. The default version is 4.24.0. You can change the version by setting the `LEAN_VERSION` environment variable. If no version is set, then 4.24.0 is used.
 >NOTE: The Lean 4 version must match the version of the Lean 4 project you are working with.
 ```bash
-export LEAN_VERSION="4.7.0-rc2"
 install-lean-repl
-# ^^ Change the LEAN_VERSION to the version of Lean 4 you are working with.
-# ^^^ Example: export LEAN_VERSION="4.15.0" to use Lean 4.15.0
-# itp-interface supports up to Lean 4.17.0
+# To use a different Lean version, set LEAN_VERSION before running:
+# export LEAN_VERSION="4.17.0" && install-lean-repl
 ```
 
 3. Run the following command to build the REPL for Lean 4. Make sure that `lean --version` returns the correct version before running the command below. If not then check if `$HOME/.elan/bin` is in your path. Recommended to run `source $HOME/.elan/env` before running the command below.

 4. Create a `Miniconda` environment and activate it.
 
+### Python 3.14 Free-Threading Support (Optional)
+
+For Python 3.14 with free-threading (GIL-free) support, create a conda environment using:
+```bash
+conda create -n py314-ft python=3.14 python-freethreading -c conda-forge
+conda activate py314-ft
+```
+
+This enables true parallel execution for computational threads. You can verify free-threading is working by running:
+```bash
+python src/test/test_python314_threading.py
+```
+
+**Note**: When using Python 3.14 free-threading:
+- Ray is not supported (Ray doesn't support Python 3.14 yet)
+- The interface will automatically fall back to thread-based parallelism using `ThreadPoolExecutor`
+- `psutil` is not available in free-threading builds, so memory logging is disabled
+- **Isabelle/PISA is not supported** - grpcio and protobuf are not compatible with Python 3.14's free-threading mode. Use Python < 3.14 for Isabelle support
+- The `run-itp-data-gen` command now auto-detects Python version and uses Hydra-free mode for Python 3.14+
+
 5. Run the commands for installing the Lean 4 interface as mentioned in [Quick Setup for Lean 4](#quick-setup-for-lean-4).
 
 6. Add the following to your `.bashrc` file for Lean:
