📊 Evals: ICPC Breakthrough & Real‑world Agent Tests

Study: ROUGE overstates hallucination detectors; LLM‑judge cuts AUROC up to 45.9%

A new paper argues ROUGE misaligns with human judgment, inflating hallucination‑detection results; when re‑scored with an LLM‑as‑Judge aligned to humans, AUROC drops as much as −45.9% (e.g., Perplexity on NQ‑Open with Mistral). It also finds many detectors correlate with answer length rather than truth, and that repetition can game overlap metrics. paper overview, metric drops, length confounder, paper link

🧩 Agent Interop & MCP Patterns

MCP usage and safety patterns keep evolving: security tradeoffs with dynamic tools vs curated static tools; registries and docs strengthen. Excludes dev‑tool launches already listed.

Vercel’s mcp-to-ai-sdk turns dynamic MCP tools into static, safer SDK tools

Vercel is proposing a pragmatic fix for flaky, risky MCP integrations: generate static AI SDK tools from MCP servers, so agents use pinned, reviewable specs instead of live‑changing tool descriptions. This mitigates prompt injection, capability drift, token bloat, and tool‑call errors.

The approach compiles MCP tool schemas into static AI SDK tools, reducing attack surface from injected descriptions and unexpected server updates Vercel blog, and Vercel blog post
It cuts token usage (GitHub’s MCP server can add ~50k tokens) by stripping unused tools and oversized schemas from prompts Vercel blog
Tool‑call accuracy improves by stabilizing names/schemas and eliminating description drift during agent planning Vercel blog
Complementary docs for MCP in the AI SDK landed recently to help teams adopt the pattern AI SDK MCP docs, and Model Context Protocol (MCP) Tools

Developers flag MCP servers for token bloat, unused tools and frequent crashes

A widely‑shared complaint sums up current MCP growing pains: servers expose tools that are never called, inflate context windows (driving token costs), and crash hard enough to break sessions—especially in coding agents at scale.

Token burn: auto‑loaded tool catalogs bloat prompts, making teams ask why their agent spends so many tokens even when tools aren’t invoked dev critique
Reliability: crashes propagate through agent stacks, interrupting runs and damaging user trust dev critique
Practical takeaway: right‑size tool sets, prefer static tool generation, and add filters/namespaces to limit what the agent sees at planning time dev critique

GitHub’s MCP Registry gains early traction; VS Code installs and OSS sync highlighted

The new GitHub‑backed MCP Registry is drawing usage fast, with developers noting one‑click installs (currently VS Code‑only) and auto‑sync from the OSS Community Registry—building on its launch. Early listings already show top web‑data tools surfacing.

Registry details: each MCP server is backed by a GitHub repo, and the catalog auto‑displays OSS entries that developers self‑publish; current UI lacks filters for local vs remote tools registry notes, and repo overview
Early momentum: Firecrawl touts MCP v3 and a top spot in the new registry, signaling fast community uptake for web search/scrape tools firecrawl update
Developer UX: VS Code installation is supported first; broader IDE support and server filtering are common requests from early testers registry notes, and GitHub MCP profile

Hidden PDF text can hijack LLM peer‑reviews, flipping accept rates to 0%–100%

A study shows that invisible PDF text (white‑on‑white, tiny fonts) survives conversion to Markdown and can bias LLM‑generated peer‑review forms—some models outputting 100% accept under positive injection and 0% under negative, far from the human baseline (~43% accept). paper summary

Simulated ICLR workflows with fixed forms found neutral prompts also elevated acceptances vs human baseline, suggesting systematic bias in automation. paper summary
Models that looked “resistant” often broke form constraints (illegal scores/fields), making their outputs unusable for copy‑paste; that is not true robustness. paper summary
Recommended mitigation is to render PDFs as images before text extraction so hidden glyphs don’t enter the model input stream. paper summary

Microsoft: ICL is real learning but needs 50–100 shots and fails under shift

A large empirical study finds in‑context learning acts like real learning but relies heavily on exemplar statistics: with 50–100 examples, accuracy climbs and model differences narrow; prompt wording matters less than intact exemplars; but robustness collapses under distribution shift and “salad‑of‑thought” scrambling. overview, many‑shot gains, exemplar vs wording, and robustness

Many‑shot regime: gains become steady past ~50 examples; few‑shot often insufficient for hard tasks many‑shot gains
Instructions vs exemplars: replacing instructions with word salad eventually recovers, but corrupting exemplars tanks performance exemplar vs wording
Fragility: strong brittleness OOD; chain‑of‑thought and auto prompt optimization particularly sensitive robustness
Task variance: similarly shaped tasks can diverge by >30% accuracy, highlighting shallow heuristic pickup over deep structure task variance

Perceptron unveiled Isaac 0.1, a compact 2B perceptive‑language model built for the physical world, with open weights and an SDK. It focuses on grounded pointing, VQA, OCR, and in‑prompt visual adaptation (few‑shot), and is already runnable via a public demo, HF weights, and fal hosting launch thread, Perceptron blog, Hugging Face org, and Perceptron SDK.

Grounded spatial intelligence: precise pointing and localization through occlusion/clutter; ask “what’s broken?” and get a visually cited answer grounding demo, and conversational pointing
In‑context learning for perception: add a few annotated examples (defects/safety flags) and the model adapts without YOLO‑style fine‑tuning few‑shot examples
Visual reasoning: OCR, dense scenes, multi‑resolution inputs; targeted for low latency and tail‑latency constraints (edge viability) visual reasoning
Try it and deploy: live demo and weights, plus a provider‑agnostic SDK and fal integration for quick experiments Perceptron demo, Perceptron SDK, and fal blog post

IBM debuts Granite‑Docling‑258M, an Apache‑2.0 document VLM for faithful PDF→HTML/MD conversion

IBM released Granite‑Docling‑258M, a 258M‑parameter image+text→text model that converts PDFs to structured HTML/Markdown with preserved layout, equations, tables, code blocks, and captions—wired directly into the Docling toolchain, under Apache‑2.0 model overview and HF collection.

Architecture: SIGLIP2‑base vision encoder + Granite‑165M LM with a pixel‑shuffle projector (IDEFICS3‑style), keeping the model small yet layout‑aware model notes
Capabilities: full‑page or region‑specific conversion; inline math and display equations; table and code formatting; basic multilingual support (EN + experimental ZH/JA/AR) deep dive
Tooling: Docling CLI/SDK outputs HTML/MD (incl. split‑page overlays) so downstream systems maintain reading order and structure rather than lossy plain text usage details

MiniCPM‑V 4.5 pushes on‑device VLMs, with a public demo and an open iOS cookbook

OpenBMB’s 8B MiniCPM‑V 4.5 is drawing praise for factual correction and reasoning, with a live demo and an iOS cookbook to run it locally on iPhone/iPad via their open‑sourced app user demo praise, HF demo, and iOS app repo.

On‑device focus: runs on Apple devices (MLX) and ships examples to stand up real multimodal apps without external dependencies deployment note
Practical strengths: community reports highlight strong "thinking" and robustness on vision‑questioning tasks despite the small footprint user demo praise
Getting started: try the hosted demo first, then clone the cookbook for local builds and quantized deployments on iOS HF demo and iOS app repo
