Measure post-training and scaffold changes as separate evaluation variables

METR’s March 2024 study compares model versions and agent scaffolds on 195 tasks across twelve families. Later post-training versions of the same base models improved measured autonomy, while the additional scaffold gains studied were small and not statistically significant. The task selection, limited enhancement methods and lack of model-weight access constrain generalization.

GEPA: use execution feedback to improve prompts and agent programs

Lakshya Agrawal’s publisher notes describe GEPA’s reflective search: inspect execution traces and errors, propose text changes, score candidates, and retain alternatives that work well on different examples. Optimize Anything extends the editable object from prompts to programs, skills and policies. The reusable method depends on informative feedback and a suitable evaluator.

Research-agent speedruns: control access to prior work before claiming discovery

Elie Bakouch’s publisher notes describe coding agents proposing optimizer changes, submitting cluster jobs and checking whether results improve a constrained training benchmark. Agents could consult community submissions, and some runs received human prompts to continue. Reported record improvements therefore mix independent search with reuse of existing research. No novel optimizer emerged in the account.

Agent-written GPU kernels: a local benchmark win can slow the full model

Tejas Bhakta’s publisher notes describe a kernel-optimization loop that proposes changes, checks correctness, benchmarks them and keeps or reverts each candidate. Humans supply the higher-level optimization idea and target-hardware context. The central failure mode is optimizing an isolated metric: disabling CUDA graphs or testing only short contexts can make the kernel score improve while inference worsens.

Visual reasoning evaluations: require evidence from the actual image

Andrew Dai’s publisher notes describe counting and video-tracking failures in which scene recognition substitutes for inspecting the visible details. A partial chessboard can elicit the familiar count for a whole board; a video answer can omit changes that occurred earlier. These are reported examples rather than measured failure rates.

Document context layers: combine fast parsing with selective source inspection

Jerry Liu’s publisher notes separate document parsing, storage and recurring workflows from an agent’s iterative retrieval loop. A fast initial parse can make a collection searchable, followed by deeper visual inspection of selected tables or charts. The design preserves source citations and flags uncertain extracted values before they enter downstream systems.

METR proposes evidence questions for frontier-model risk disclosure

METR’s June 2025 proposal asks what AI developers should disclose about serious model risks, including internal capabilities, monitoring, safety investigations and incident history. It organizes questions around information that outsiders cannot reliably infer from public model behavior, and discusses disclosure incentives and the limits of developer self-reporting. Sensitive evidence could be assessed by trusted reviewers rather than exposed publicly.

Agent memory: separate stored facts, past examples, and instruction updates

Jake Broekhuizen distinguishes retaining conversation traces from producing memory that changes later behavior. Facts, useful past examples, and procedural instructions serve different purposes and need different update policies. The talk describes extracting lessons from runs, storing them outside the immediate conversation, and loading relevant material on later tasks.

Inference latency: separate queueing, prefill and token generation

Charles Frye explains an inference engine as a request server, a scheduler and a model runner. Queueing and prompt prefill contribute to time to first token; repeated decoding governs later token delivery. KV caching, prefix reuse, batching, CUDA graphs and speculative decoding address different parts of that workload and introduce their own resource tradeoffs. A museum application example illustrates how a demand spike can worsen both initial and subsequent token latency.
