OpenAI Python SDK v2.45.0 Adds GPT-5.6-SOL Support

OpenAI released version 2.45.0 of its Python SDK on July 9, 2026, adding support for what appears to be GPT-5.6-SOL model updates. The release includes one feature addition and a bug fix addressing beta resource accessors.

What Changed

The primary feature addition in v2.45.0 is labeled "gpt-5.6-sol updates" in the commit log, though OpenAI has not publicly disclosed details about a GPT-5.6-SOL model. The SDK update suggests either an upcoming model release or internal testing infrastructure.

The release fixes a regression that affected beta resource accessors, which had been removed in a previous version. These accessors provide developers with programmatic access to OpenAI's beta features and experimental API endpoints.

Implementation Details

Developers using the OpenAI Python SDK can upgrade to v2.45.0 via pip:

pip install --upgrade openai

The full changelog is available in the GitHub repository comparing v2.44.0 to v2.45.0. The release went through standard automation retriggers before final publication.

What This Means

The reference to "gpt-5.6-sol" in OpenAI's SDK suggests the company may be testing or preparing to release a new model variant, though no official announcement has been made. The "sol" suffix is not standard in OpenAI's naming conventions, which typically use designations like "turbo" or model size indicators.

The restoration of beta resource accessors indicates OpenAI is maintaining support for experimental features in its Python SDK, allowing developers to access pre-release capabilities. Organizations building on OpenAI's platform should update to v2.45.0 to ensure compatibility with upcoming beta features and to benefit from the bug fixes.
