Ahmed Ibrahim e7bffc5a20 [codex] Accept string input for Python turns (#23162)
## Summary
- Allow thread.turn and turn.steer, including async variants, to accept
RunInput so plain strings work alongside typed input objects.
- Export RunInput and update the SDK artifact generator so regenerated
turn methods keep the same signature and normalization.
- Update docs, examples, notebook cells, and tests to use string
shorthand for text-only turns while keeping typed inputs for multimodal
input.

## Validation
- uv run --extra dev ruff format .
- uv run --extra dev ruff check --output-format=github .

Python SDK Examples

Each example folder contains runnable versions:

  • sync.py (public sync surface: Codex)
  • async.py (public async surface: AsyncCodex)

All examples intentionally use only public SDK exports from openai_codex and openai_codex.types.

Examples use plain strings for text-only turns and typed input objects for multimodal or structured input lists.

Prerequisites

  • Python >=3.10
  • Install SDK dependencies for the same Python interpreter you will use to run examples

Recommended setup (from sdk/python):

uv sync
source .venv/bin/activate

When running examples from this repo checkout, the SDK source uses the local tree and does not bundle a runtime binary. The helper in examples/_bootstrap.py uses the installed openai-codex-cli-bin runtime package.

If the pinned openai-codex-cli-bin runtime is not already installed, the bootstrap will download the matching GitHub release artifact, stage a temporary local openai-codex-cli-bin package, install it into your active interpreter, and clean up the temporary files afterward.

The pinned runtime version comes from the SDK package dependency.

Run examples

From sdk/python:

python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py

The examples bootstrap local imports from sdk/python/src automatically, so no SDK wheel install is required. You only need the Python dependencies for your active interpreter and an installed openai-codex-cli-bin runtime package (either already present or automatically provisioned by the bootstrap).
