 Pyodide works well for **text analysis, hash computation, chart generation, file processing**, and other self-contained tasks. Chart libraries like matplotlib produce base64-encoded images that Open WebUI automatically captures, uploads as files, and injects direct image links into the output — so models can display charts directly in chat without any extra setup.

-:::warning Not suited for heavy workloads
-Pyodide runs Python via WebAssembly inside the browser, which is **significantly slower** than native Python execution. Large datasets, complex computations, ML model training, and CPU-intensive tasks will be noticeably slow or may hit memory limits. Additionally, many Python packages that rely on C extensions, system calls, or native binaries are **not available** in Pyodide — the library ecosystem is a limited subset of what a full Python environment offers. For demanding workloads, use **Open Terminal** instead, which provides full native performance and unrestricted package access inside a Docker container.

+Pyodide runs Python via WebAssembly inside the browser. The AI **cannot install additional libraries** beyond the small fixed set listed below — any code that imports an unsupported package will fail. Execution is also **significantly slower** than native Python, and large datasets or CPU-intensive tasks may hit browser memory limits.

 ### Supported Libraries
 
-Pyodide includes the following pre-configured packages:
-
-- micropip
-- packaging
-- requests
-- beautifulsoup4
-- numpy
-- pandas
-- matplotlib
-- scikit-learn
-- scipy
-- regex
-
-:::note
-Packages not pre-compiled in Pyodide cannot be installed at runtime. For additional packages, consider using Open Terminal or forking Pyodide to add custom packages.

-:::warning Performance Limitations
-Pyodide executes Python via WebAssembly in the browser, which is **significantly slower** than native execution. Heavy computations, large dataset processing, ML training, and memory-intensive tasks may be slow, unresponsive, or hit browser memory limits. Many packages that depend on C extensions or system-level libraries are also unavailable. For demanding workloads, use **[Open Terminal](/features/chat-conversations/chat-features/code-execution#open-terminal)** instead — it provides full native performance and unrestricted package access.
+Pyodide includes the following packages, which are auto-detected from import statements and loaded on demand:
+
+| Package | Use case |
+|---------|----------|
+| micropip | Package installer (internal use) |
+| requests | HTTP requests |
+| beautifulsoup4 | HTML/XML parsing |
+| numpy | Numerical computing |
+| pandas | Data analysis and manipulation |
+| matplotlib | Chart and plot generation |
+| seaborn | Statistical data visualization |
+| scikit-learn | Machine learning |
+| scipy | Scientific computing |
+| regex | Advanced regular expressions |
+| sympy | Symbolic mathematics |
+| tiktoken | Token counting for LLMs |
+| pytz | Timezone handling |
+
+The Python standard library is also fully available (json, csv, math, datetime, os, io, etc.).
+
+:::warning No runtime installation
+The AI **cannot install additional libraries** beyond the list above. Any code that imports an unsupported package will fail with an import error. Packages that require C extensions, system calls, or native binaries (e.g., torch, tensorflow, opencv, psycopg2) are **not available** and cannot be made available in Pyodide. Pyodide is best suited for **basic file analysis, simple calculations, text processing, and chart generation**. For full Python package access, use **[Open Terminal](/features/chat-conversations/chat-features/code-execution#open-terminal)** instead.
