Greptile Summary

This PR re-submits the v1.82.3 release notes (reverted PR #23816) with four targeted corrections: provider count fixed to 5, Nebius AI PR link corrected to #22614, ZAI docs link updated to the dedicated /docs/providers/zai page (which confirmed exists), and the duplicate PR link for SageMaker Nova resolved by keeping #21542 distinct from Nebius AI's #22614. All four claimed fixes are verified in the diff.

Key observations:

• All four stated fixes are correctly applied and verified against the repository (dedicated zai.md and nebius.md docs pages confirmed to exist)
• The release notes cover a large surface area: 116 new models, 5 new providers, security patches, and performance fixes
• One minor style inconsistency remains: the Key Highlights bullet describes gpt-5.4 with "1M context" while the models table lists "1.05M" for the same model

Confidence Score: 4/5

• This is a documentation-only PR; no runtime code is changed, making it safe to merge with minor cleanup.
• All four fixes from the PR description are correctly applied and independently verified. The only remaining issue is a minor intra-document inconsistency (1M vs 1.05M context window) that has no functional impact. No code, schema, or configuration files are touched.
• No files require special attention — this is a docs-only change.

Important Files Changed

Filename	Overview
docs/my-website/release_notes/v1.82.3.md	New release notes file documenting v1.82.3 changes — all four fixes from the reverted PR #23816 are correctly applied (5 providers, correct Nebius AI PR link, dedicated ZAI doc page, distinct SageMaker Nova PR link); one minor contextual inconsistency found between Key Highlights and model table for gpt-5.4 context window.

   Context window mismatch: "1M" vs "1.05M"

   The Key Highlights bullet describes gpt-5.4 as having "1M context", but the models table below lists its context window as 1.05M. These values are inconsistent within the same document. Consider either rounding the table entry to 1M or updating the Key Highlights to read "1.05M context" so readers get a consistent figure.
