docs(readme): update convergence table, latest news, and outdated links

[sbhavani]

Description

Updates README add missing format support documentation, update news section, and fix broken/outdated links.

Type of change

• Documentation change (change only to the documentation, either a fix or a new content)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Infra/Build change
• Code refactoring

Changes

• Add MXFP8 and NVFP4 format support to highlights and description
• Update FP8 convergence table with MXFP8 results from arxiv paper
• Remove outdated JAX Toolbox links and "available on request" entries
• Update Docker container versions to 26.01
• Fix DeepSpeed and Lightning integration links
• Add Nemotron 3 paper to Latest News
• Add quickstart notebook link after PyTorch example

Checklist:

• I have read and followed the contributing guidelines
• The functionality is complete
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Greptile Overview

Greptile Summary

Updated README documentation to reflect current Transformer Engine capabilities and fix outdated information. Added MXFP8 and NVFP4 format support documentation for Blackwell GPUs, updated the FP8 convergence table with new MXFP8 results from arxiv paper, updated Docker container versions from 25.08 to 26.01, fixed broken/outdated integration links (DeepSpeed and Lightning), added Nemotron 3 paper to Latest News, and corrected notebook references to use the existing fp8_primer.ipynb instead of the non-existent quickstart.ipynb.

Key changes:

• Added MXFP8 and NVFP4 format support mentions in description and highlights
• Updated convergence table with LLM-8B and MoE-16B Megatron Core results
• Removed outdated "available on request" entries and broken JAX Toolbox links
• Updated Docker container versions to current release (26.01)
• Fixed integration documentation links to point to valid resources

Minor issue:

• Inconsistent spacing in convergence table for "Megatron Core" entries (3 spaces instead of 2)

Confidence Score: 4/5

• Safe to merge with minor formatting inconsistency
• Documentation-only changes that improve accuracy and fix broken links. The referenced notebook file exists, convergence table updates appear legitimate with valid arxiv reference, Docker versions are reasonable progression, and integration links point to valid resources. Only minor style issue is inconsistent table spacing.
• No files require special attention - minor style fixes optional

Important Files Changed

The referenced quickstart.ipynb file does not exist in docs/examples/. The actual notebooks in that directory are fp8_primer.ipynb, advanced_optimizations.ipynb, and te_jax_integration.ipynb. Consider using one of these existing notebooks or creating the quickstart notebook before merging.

extra space before "Megatron Core" - should have 2 spaces like other rows, not 3
