We compared the top model from each family by net improvement score and median cost per task. Family is defined as variants within the same model base name. GPT-6 Astra and Claude Fable 5.1 stand out: both cost far more than other models from their respective labs despite relatively close performance. By @OpenAI : - GPT-6 Astra (Max): +11.7% | $3.94/task - GPT-5.6 Sol (xHigh): +7.0% | $1.03/task By @AnthropicAI : - Claude Fable 5.1 (Max): +13.7% | $4.40/task - Claude Opus 5 (High): +10.2% | $2.07/task 💬 8 🔄 7 ❤️ 114 👀 8391 📊 22 ⚡

OpenAI's GPT-6 Astra scores 66.7% on wet-lab benchmark

The gain came with fewer reasoning tokens, so the benchmark improvement reflects better raw-data reading rather than longer thinking. Rubrics that reward partial credit and error-spotting make this a more realistic measure of lab readiness than pass/fail tests. Teams evaluating agents for scientific work can use it to compare GPT-6 Astra against GPT-5.6 Sol on messy real-world inputs.

VIALS-AA leaderboard ranks models on life science visual reasoning

The 29× cost gap between frontier models with a 3-point score spread changes the economics of choosing a model for scientific agent workloads. Teams building lab-automation or biotech analysis tools can use the per-task cost and turn counts to pick models that fit their budgets. The 19-point deficit of open weights models like Kimi K3.1 Pro also marks a concrete ceiling for on-premise deployments.

Nace AI's 27B Drex Max Picks Instead of Generating Tokens

Routing thousands of micro-decisions to a pick-only model could cut agent orchestration costs by orders of magnitude where the answer space is a finite option list, not free text. Builders running multi-step agent pipelines can plug it in as a cheap decision layer while keeping a general model for generation. The gap on HLE shows it is a narrow tool, not a replacement for reasoning models.
