The one thing

01

vLLM 0.28.0 ships Model Runner V2 defaults and breaks bitsandbytes-in-tree; Claude Code latest is 2.1.247 while stable stays 2.1.231.

vLLM v0.28.0 (26 Aug) raises max_num_batched_tokens from 8192 to 16384, enables Mamba prefix caching by default, and matures Model Runner V2 (E/P/D disaggregation, tiered KV offload including disk, multi-layer MTP KV).1 Breaking: bitsandbytes moves out-of-tree; Transformers floor is 5.15.0; calculate_kv_scales and override_attention_dtype are removed.1

npm @anthropic-ai/claude-code: stable still 2.1.231; latest/next → 2.1.247.23 2.1.247 adds SendFeedback drafts and fixes /compact / --agent summarization under the wrong system prompt.3 Channel policy from #015 stands.

VERDICT · BREAKING — vLLM: checklist bnb plugin + Transformers ≥5.15 before upgrade. Claude Code: latest ≥2.1.247 for those fixes; stable remains 2.1.231.

The conversation

01
The claim — including ours

vLLM 0.28 is a real serving break; Claude Code still has no native AGENTS.md; Cursor permanently raised included Grok usage.189

From the floor
  • vLLM v0.28.0 release notesPrimary, 26 Aug

    Defaults up; bitsandbytes out-of-tree; Transformers ≥5.15.1

  • @trq212 (Claude Code) via X digestVendor, digest 26 Aug 05:30 (~24.5h old at window close)

    Easier AGENTS.md / prompt mods coming; per-model prompts stay; interim @AGENTS.md from CLAUDE.md.8

  • @leerob (Cursor) via X digestVendor, same digest

    Included Grok usage raised permanently across first-party Cursor models.9

Our take

Upgrade vLLM only after the bnb/Transformers checklist. AGENTS.md native support is still unshipped. Re-check Cursor quotas if Grok is default.
