Microsoft Research and UC Berkeley open-source TokenEconomizer, a plugin that cuts Claude Code and Codex costs by 18.4–30.9% on SWE-Bench without changing the agent

Microsoft Research, Microsoft Security and UC Berkeley open-sourced TokenEconomizer on GitHub (Apache 2.0, v0.1.0 released October 26), a plugin for Claude Code, Codex, GitHub Copilot CLI and Pi, with experimental opencode support. It learns from earlier sessions in the same repository: micro-skills remember repo facts, tool pruning drops tool definitions that go unused, and a loop guard nudges an agent that is stuck. The paper reports 18.4–30.9% lower mean cost across five agent and model combinations on 277 SWE-Bench tasks (paper figures).

Microsoft Research and UC Berkeley open-source TokenEconomizer, a plugin that cuts Claude Code and Codex costs by 18.4–30.9% on SWE-Bench without changing the agent

Key Takeaways

  • Cost: on 277 SWE-Bench tasks across 6 repositories and 5 agent and model combinations, mean cost fell 18.4–30.9%, and all 30 repository-by-combination cells got cheaper (paper figures, including the plugin's own model calls)
  • Success rate: Pass@1 rose in 4 of 5 combinations, e.g. Copilot CLI with Sonnet 5 cost 18.4% less with Pass@1 +2.6, while Claude Code with Opus 4.8 cost 30.9% less with Pass@1 -1.0
  • Three mechanisms: micro-skills (repo facts stated only after three sessions confirm them), tool pruning (by default a tool unused over 10 prompts across 2 sessions is left out), and a failure-loop guard (one redirect when a judge is at least 0.7 confident, never stopping a turn itself)
  • Generalization: 16–21% lower cost on Web-Bench and 6–20% lower on two security-auditing benchmarks where every task is a new repository
  • Deployment: Apache 2.0, Python 3.10+, no API key of its own, and learned experience stays local in ~/.tokeneconomizer

Cloudflare discloses a cross-request KV cache leak in GLM-5.3 on Workers AI: a config mismatch plus an SGLang bug let 155 responses carry other users' data over 13 days

In an Oct 26 incident report on its blog, Cloudflare said that between Aug 27 and Sep 9, 155 responses from GLM-5.3 on Workers AI (@cf/zai-org/glm-5.3) to prompts longer than 681,280 tokens contained data from other customers' recent requests, all returned with HTTP 200. The cause was a prefill KV cache pool smaller than the 1,048,576-token context window, combined with an SGLang bug in disaggregated prefill/decode mode. Cloudflare found no evidence of deliberate exploitation, has fixed it, and recommends operators upgrade to SGLang v0.5.22 or later.

Cloudflare discloses a cross-request KV cache leak in GLM-5.3 on Workers AI: a config mismatch plus an SGLang bug let 155 responses carry other users' data over 13 days

Key Takeaways

  • Scope: 155 responses between 2026-08-27 and 09-09, all to prompts over 681,280 tokens; Cloudflare confirmed no other Workers AI model was affected
  • Cause 1: GLM-5.3 advertised a 1,048,576-token context but the prefill KV pool held only 681,280 tokens; after the fix the pool holds about 2.04 million tokens, roughly twice the context
  • Cause 2: SGLang marked over-length requests as rejected and swapped in a one-token placeholder without aborting, so the decode node read stale cache pages from earlier requests
  • Response: report from Gadi Evron of Knostic via HackerOne on Sep 8; model taken offline within 40 minutes of declaring the incident on Sep 9 and restored at 19:40 UTC that day
  • Action: teams running SGLang should upgrade to v0.5.22 or later and check KV pool size against context length directly

vLLM v0.32.0: 814 commits, built-in /v1/systemone structured-decision endpoint, NVFP4 KV cache on more GPUs, and 43–85% more req/s with multiple API workers

vLLM shipped v0.32.0 on Oct 18 with 814 commits from 363 contributors (121 new). Highlights: a default-served POST /v1/systemone structured-decision endpoint and a generic hf tool/reasoning parser; NVFP4 KV cache on SM8x/SM90/SM12x and FP8 KV by default for GLM-5.x on SM100; Model Runner V2 gains a GPU n-gram speculator and Elastic EP and becomes the ROCm default; three security advisories are fixed, default CORS is restricted, and Python 3.10 is dropped.

vLLM v0.32.0: 814 commits, built-in /v1/systemone structured-decision endpoint, NVFP4 KV cache on more GPUs, and 43–85% more req/s with multiple API workers

Key Takeaways

  • Scale: 814 commits from 363 contributors (121 new); see the release notes.
  • Structured decisions: POST /v1/systemone is new and served by default for choice/score questions, including Cloudflare/clef-omni and LiquidAI/d1-3B; --tool-call-parser hf reads a checkpoint's response_template so no model-specific parser is needed.
  • Low-precision KV: GLM-5.x defaults to FP8 KV on SM100, halving KV memory per rank with 2.3–5.5% more throughput at a 7–11% TTFT cost (PR benchmark, vendor figures); ROCm adds a 4-bit KV cache at about 2x FP8 density.
  • Serving: with --api-server-count above 1, connections go to the least-loaded worker for 43–85% more req/s on short requests (Qwen3-0.6B, 32 in / 1 out tokens, PR benchmark).
  • Breaking: Python 3.10 dropped, default CORS origins restricted, cascade attention removed, and max_tokens is no longer reserved from the context window.
