Akka runs spec-driven AI porting experiment across 65 open-source projects

Akka tested a spec-driven workflow for AI-assisted software porting across 65 open-source projects, using a delivery harness that cycled through discovery, specification, porting, benchmarking, and improvement. The initial tranche took 99.3 hours and consumed 9.41 billion tokens; Akka reported lines-of-code or performance improvements in 57 of the 65 ports and used Claude with Akka Specify for implementation, with Sonnet averaging 61 minutes per port versus 120 minutes for Opus (Opus used ~40% fewer tokens).

Anthropic releases Claude Sonnet 5.5 claiming faster output and up to 30% lower per-task costs

Anthropic has released Claude Sonnet 5.5, the second model in its Claude 5.5 family; the company says the model generates output more than 30% faster and reduces per-task costs by up to 30% through more efficient token usage while nearly matching Opus 5.5 on several coding and knowledge-work benchmarks. Sonnet 5.5 is available on AWS, Google Cloud, and Azure as model ID "claude-sonnet-5-5," and Anthropic says it adds new safeguards against cybersecurity risks and distillation attacks — independent verification of the performance and cost claims is pending.

Anthropic partners with Accenture (Faculty) for embedded evaluation of frontier AI

Anthropic announced a non-exclusive partnership with Accenture’s specialist AI business, Faculty, to embed independent evaluators inside Anthropic to red-team models, conduct alignment assessments, and test safeguards. Both companies expect to invest at least $1 billion each over the next five years; Anthropic will fund Accenture’s work directly while also piloting other evaluators (e.g., METR). The announcement follows recent incidents involving Claude models and notes ongoing independent reviews and evolving standards for embedded evaluation.
