[Bug]: openai dependency still pinned to <3.0.0 in latest release, blocks packages requiring openai>=3.0.0 #40317
Description
What Happened
litellm's pyproject.toml pins openai>=2.20.0,<3.0.0 even in the latest
release (1.100.0). This makes it impossible to install litellm alongside
any package that requires openai>=3.0.0.
openai's v3.x line has been on PyPI for a while now (currently 3.9.0), so
the <3.0.0 ceiling appears to be stale rather than an active compatibility
guard.
Reproduction
In a project that depends on both litellm==1.99.0 (or 1.100.0) and another
package requiring openai>=3.0.0, uv lock fails to resolve:
× No solution found when resolving dependencies for split (markers:
│ python_full_version == '3.14.7' and sys_platform == 'win32'):
╰─▶ Because some-package[openai]==X.Y.Z depends on openai>=3.0.0 and
litellm==1.99.0 depends on openai>=2.20.0,<3.0.0, we can conclude that
litellm==1.99.0 and some-package[openai]==X.Y.Z are incompatible.
And because llm depends on litellm==1.99.0, we can conclude that llm and
some-package[openai]==X.Y.Z are incompatible.
And because llm depends on some-package[openai]==X.Y.Z and your
workspace requires llm[all], we can conclude that your workspace's
requirements are unsatisfiable.

Howdy! I’m one of OpenAI’s Python SDK maintainers, new to LiteLLM. #43209 attempts SDK 2/3 compatibility; limitations are detailed there. I’d appreciate feedback!
