Trying to use o3 and o4-mini in Playground with Responses API.
Adding two tools: DeepWiki MCP and Code Interpreter. The prompt asks to look up a repository and write a tutorial about it, using Code Interpreter to test the code.
I can send my prompt and read the assistant’s response. But when I give a follow-up question, it often (but not always) fails with this error:
Item ‘rs_685821f77308819ab94934742e9e1ef301af0ff6a9a0da70’ of type ‘reasoning’ was provided without its required following item.
If I was writing the code, there might be workarounds but I need to demonstrate something in the Playground for a course I’m making.
I see more reports of this problem on this forum but the system is not allowing me to post links.
Is there really no solution in sight?
Providing the full code below. BTW, another bug is that the code snippet uses the object null which doesn’t exist in Python, it should be None instead.
from openai import OpenAI
client = OpenAI()
response = client.responses.create(
model="o3",
input=[

All code examples are executed live with the Code-Interpreter so you can immediately verify them or adapt them to your own exploration.\n\n---\n\n# 1-Hour Crash-Course Study Plan – Pandas Fundamentals\n\nTotal time: 60 min. Required software: an interactive Python session (Jupyter, VS Code, or any IDE of your choice).\n\n0–5 min Installation & First import \n• `pip install -U pandas pyarrow` (pyarrow gives you the new, faster backend) \n• In a REPL or notebook: \n```python\nimport pandas as pd, numpy as np\npd.__version__\n```\n\n5–15 min “What is a DataFrame?” \n• Create small Series and DataFrames with dict/array constructors. \n• Explore attributes: `.shape`, `.dtypes`, `.columns`, `.index`. \n• Essential selectors: `.loc`, `.iloc`, boolean masks.\n\n15–25 min Reading & Writing Data \n• `pd.read_csv`, `pd.read_parquet`, `df.to_csv`, `df.to_parquet`. \n• Show basic I/O options (use `low_memory=False`, compression, etc.). \n• Quick look at dtype inference and `dtype_backend='pyarrow'`.\n\n25–35 min Vectorised arithmetic & basic stats \n• Column math, broadcasting rules. \n• Descriptive stats: `.sum()`, `.mean()`, `.quantile()`, `.describe()`. \n• Handling missing data: `.isna()`, `.fillna()`, `.dropna()`.\n\n35–45 min Sorting, filtering, assignment \n• `.sort_values`, `.sort_index`. \n• Conditional filtering. \n• `.assign`, `.pipe`, chaining best practices.\n\n45–60 min Aggregation with `groupby` (deep dive below) – this is the only new concept now. \n\nAfter this hour you will comfortably read / write CSV & Parquet, index and slice data, perform column maths, and understand the big idea of “split-apply-combine” that powers `groupby`.\n\n---\n\n# Tutorial – `groupby` in Pandas\n\n## 1. Why `groupby`?\n\n“Split-apply-combine” \n1. Split: break the DataFrame into groups defined by one or more keys. \n2. Apply: run a function (aggregation, transformation, or filter) on each piece. \n3. Combine: stitch the results back into a single object.\n\n## 2. Public API (what you call)\n\n```python\ndf.groupby(key, by=None, axis=0, level=None, as_index=True,\n sort=True, group_keys=True, observed=False,\n dropna=True)\n```\n\nTypical call signatures \n• `df.groupby(\"col\")` – single column key. \n• `df.groupby([\"col1\", \"col2\"])` – multiple keys. \n• `df.groupby(df[\"col\"].dt.year)` – pass any Series-like. \n• `.agg({...})`, `.transform()`, `.apply()`.\n\n## 3. How does it work internally? (Based on current `pandas/core/groupby/`)\n\nDeep-dive (quick):\n\n1. Factory: `pd.DataFrame.groupby` hands work to `DataFrame.groupby` method which immediately constructs a `DataFrameGroupBy` object defined in `pandas/core/groupby/groupby.py`. \n\n2. The constructor validates keys, resolves indexes, and calls the lower-level `groupby._GroupBy.grouper` which is an instance of `pandas/core/groupby/grouper.py:Grouper`. \n\n3. `Grouper` maps each row into an integer group id array (`codes`), leveraging highly optimised Cython/NumPy routines. \n\n4. Aggregation functions are dispatched through the `GroupBy._cython_agg_general` path if they are listed among fast built-ins (sum, mean, min, max, count, std, var, prod, first, last). Otherwise `GroupBy._agg_py_fallback` is used.\n\nThe modern code path prefers Arrow-backed arrays where possible (see `pandas/core/algorithms.py:take_nd_arrow`).\n\nYou almost never touch these internals, but knowing them explains:\n\n• Why some ops are much faster than others. \n• Why grouped index levels behave as they do (`as_index` flag). \n• How categorical / Arrow types get special-cased.\n\n## 4. Hands-on examples (executed below)\n\n"

"text": "# Results of Live Examples\n\nThe five snippets above ran successfully and show:\n\n1. Sum per group (`Series` result). \n2. `.agg` supplying a dict of new-column : (old-column, func) tuples. \n3. Multi-index grouping on (`city`, `year`). \n4. `.transform` keeps the original row count so you can attach a derived column. \n5. `.filter` removes whole groups if the predicate is False.\n\nAll these operations rely on the fast path noted earlier: when you pass a built-in aggregation name, pandas resolves it to `_cython_agg_general` → Cython/NumPy loops → optional Arrow kernel.\n\n## 5. Tips & Gotchas\n\n• `as_index=False` – want the grouping keys back as regular columns? Pass this flag or call `.reset_index()` afterwards. \n• `observed=True` – with categorical keys, ignore categories that do not appear (saves memory). \n• Custom Python functions in `.apply` are convenient but slow. If performance matters, prefer `.agg(\"mean\")`, `.sum()`, etc., or write a vectorised `.transform`. \n• Arrow backend: many groupby aggregations are already Arrow-accelerated; the remainder will fall back without error.\n\n## 6. When `groupby` is NOT needed\n\n1. Simple per-column reductions (`df[\"sales\"].mean()`). \n2. Filtering rows independent of other rows (`df[df[\"sales\"] > 10]`). \n3. Window statistics (`rolling`, `expanding`, `ewm`).\n\nIf you find yourself writing `.groupby().apply(lambda g: g.head(1))`, consider `.drop_duplicates` or `DataFrame.idxmax` for better clarity and speed.\n\n---\n\n# Summary\n\n• You now have a 60-minute road-map from zero to DataFrame fluency. \n• Internally, `groupby` is powered by the `Grouper` object and fast Cython loops (`_cython_agg_general`), with Arrow acceleration on modern dtypes. \n• Practical knowledge: choose aggregation vs. transform vs. filter; mind `as_index`, `observed`, performance of Python `apply`.\n\nHappy data wrangling!"
