DSB-IFEval tests the gap between how voice agents get benchmarked and how they get deployed. Benchmarks hand the model explicit turn-management instructions; production agents get a role description and have to infer when to listen, backchannel, interrupt or yield. Across 1,038 cases spanning eight roles and five conditioning protocols, F-Actor and PersonaPlex drop 9.7% and 4.5% under persona-only conditioning while GPT-Realtime, MiniCPM-o and Fun-Audio-Chat hold up. Architecture-dependent, so test yours rather than trusting the ranking.

Accuracy drops 30–50% well before you hit the documented context limit. Not at the limit. Before it. Cross-model testing across GPT-4.1, the Claude 4 family, Gemini 2.5, and Qwen3 quantified what everyone shipping long-context features has felt and couldn't measure (Glasp). Th...
If you have a CLAUDE.md, you're in scope. Today. arXiv 2607.14611 (cs.CR, filed July 16) evaluates prompt injection planted in the persistent memory files that agentic coding systems write and re-read across sessions. The researchers tested both Anthropic's Claude Code and Ope...
Terminal-Bench 2.1 results (entries dated June 17) put Codex CLI on GPT-5.5 first at 83.4%, Claude Code on Fable 5 second at 83.1%, and Claude Code on Opus 4.8 at 78.9%. The asterisk matters more than the ranking: Fable 5 and Mythos 5 have been export-suspended since June 12,...
In 30-day simulations where fifty shipper agents on GPT, Claude, and Gemini procured truckload capacity under real digital-freight rules, every model independently picked the same modal first-choice carrier on day one, drawing up to 76% of requests, with concentration rising s...
The same week we're celebrating AI rewriting a million lines of code, Microsoft Research dropped DELEGATE-52, and it's the cold shower this industry needs. The benchmark simulates long delegated workflows across 52 professional domains, from coding to crystallography to music...
