Summary

  • language/deepseek-r1/README.md pointed the R2 downloader at deepseek-r1-0528.uri, which resolves to DeepSeek-R1-0528 instead of the intended deepseek-ai/DeepSeek-R1 (revision 56d4cbbb4d29f4355bab4b9a39ccb717a14ad5ad) named directly above it.
  • The R2 bucket now hosts the correct checkpoint under deepseek-r1.uri (matching r2-infra/inference/index.html, which already links the correct URI). This PR brings the README in line.

Verification

  • Downloaded the model fresh via the R2 downloader using the corrected deepseek-r1.uri link (641GB, 174 files, downloader's own MD5 verification passed 174/174).
  • Independently computed md5sums for the downloaded checkpoint and for a reference copy of deepseek-ai/DeepSeek-R1 @ 56d4cbb pulled from Hugging Face.
  • Compared all 173 comparable files (weights, config, tokenizer, etc.) — all filenames and md5sums matched exactly, confirming the R2 bucket now serves the correct checkpoint.

Test plan

  • Confirmed corrected URI downloads the intended checkpoint (md5sum match vs HF reference)
  • No other references to deepseek-r1-0528.uri remain in this file

🤖 Generated with Claude Code

The README pointed at deepseek-r1-0528.uri, which resolves to
DeepSeek-R1-0528 rather than the intended deepseek-ai/DeepSeek-R1
(revision 56d4cbb) referenced above it. The R2 bucket now hosts the
correct checkpoint under deepseek-r1.uri; verified via full download
and md5sum comparison against the reference HF checkpoint (173/173
files match, zero mismatches).
