Full details: Linked Issues checkExplanation The PR centralizes context window maps and longest-prefix resolution, updates native providers, adds resolver tests, and updates GPT-5 behavior. However, the stated objective to re-export CONTEXT_WINDOW_USAGE_RATIO and DEFAULT_CONTEXT_WINDOW_SIZE from crewai.llm is not met because llm.py no longer imports those constants. Resolution Restore the re-exports of CONTEXT_WINDOW_USAGE_RATIO and DEFAULT_CONTEXT_WINDOW_SIZE from crewai.llm. Confirm that existing imports and tests using these public names continue to work. Also verify the constant name is CONTEXT_WINDOW_USAGE_RATIO, not a misspelled variant. [

OpenAICompletion.get_context_window_size() for bare gpt-5 to ensure it no longer
falls back to the 8,192-token default or truncates valid prompts.

the provider fallback for unknown deployments and models.

- Line 2373: Resolve the conflicting GPT-5 context-window expectations by
aligning the assertion near get_context_window_size with the intended registry
value used by test_openai_gpt5_and_gpt54_mini_keep_their_windows, or remove the
duplicate assertion if that test is redundant. Ensure both tests do not expect
different values for the same OpenAICompletion(model="gpt-5") configuration.
