What’s the best harness for an open model on coding and agentic tasks? We partnered with @Runta to investigate: 100B tokens and 26k trials later, the final results are coming in. Full report next week.
Genspark and Baseten Applied Research post-trained an open-weight model that beats Opus 5.5 at deep research. Starting from Qwen3.5-397B, our post-trained model scores 0.759 on @genspark_ai's internal evals, ahead of Opus 5.5 (0.738) and well above the base model (0.612). It’s now the default model in production behind Genspark’s Deep Research agent.
