Claude Fable 5.2 leads scientific visual reasoning benchmark VIALS-AA; it makes more tool calls than any other Anthropic model, unlike OpenAI models which make fewer as they get smarter VIALS-AA is our implementation of Handshake AI’s VIALS benchmark for visual reasoning in life sciences research, across artifacts such as gel blots, plasmid maps, and phylogenies. Claude Fable 5.2 (max with fallback) scores 67% on VIALS-AA, ahead of Gemini 4 Carbon (high) at 64% and GPT-6 Astra (max) at 63%. Fable averages ~37 tool calls per task, while Astra averages ~8, the fewest of any model we’ve tested. On turn 4 of this protein interaction task, Fable creates crops and asks to view them. On turn 10, it builds a color mask by thresholding color channels. On turn 17, it fits a circle to each arc and unrolls the arc into a straight strip. On turn 31, it counts the bars as peaks in an intensity profile. And on turn 41, it maps every detected spoke back on the original image to check its work. Fable batches calls on 28 of its 51 turns, averaging 1.75 tool calls per turn, compared with 1.12 for Sonnet 5.5.

We’re launching Optima. Now anyone can create a custom benchmark for their use case, leveraging Artificial Analysis’ leading research and platform Building and running benchmarks is difficult. We have distilled Artificial Analysis’ research and experience developing benchmarks into Optima, a new platform for benchmarking models on your own workloads and comparing performance, speed and cost efficiency. Optima allows you to find the best model for your task, or an equally performant alternative to your current setup at 10x lower cost or time per task. We’ve integrated Artificial Analysis' research and experience in benchmarks across the Optima workflow: ➤ Build benchmarks based on your own data and use cases: There are three ways to build a benchmark with Optima. Upload an existing evaluation dataset from your own files or Hugging Face, or import agent traces from platforms including Arize AI, Braintrust and langfuse.com. Install the Optima skill to build a benchmark using context from your coding environment and previous sessions. Or simply describe your use case and provide example inputs and outputs, and Optima will build the benchmark for you ➤ Run across the latest models: Run the same benchmark across leading models in a single click, and keep your leaderboard up to date as soon as new models are released ➤ Bring Artificial Analysis grading to your own benchmark: Evaluate responses against objective rubric criteria or using the same pairwise judging approach used for Artificial Analysis benchmarks including GDPval-AA and AA-Briefcase. For pairwise judging, select your preferred responses from a sample and Optima uses those preferences to rank models across your test set ➤ Compare performance, cost and time efficiency: Optima measures more than model performance. Cost per Task and Time per Task are tracked alongside benchmark scores, with category-level results and support for custom metrics, allowing you to compare the tradeoffs between models for your specific use case Ahead of launch, here are examples questions our beta testers answered with Optima: ➤ Which model can save me 10x the cost without a meaningful decrease in quality for my finance & accounting agent? ➤ Which model best matches the writing style of lawyers for my legal agent? ➤ Which model can best identify different elements in my custom image dataset? Optima is available today. Build your own benchmark at

Welcome to the era of embodied AI. We are launching AA-Robotics v0.1, our research preview that measures frontier language model performance on understanding, planning, and acting in the physical world. In v0.1, each model is given control of a 6-axis robot arm (5 joints and a gripper) and a simple objective. We’re releasing results for our first eight tasks today. We find that frontier language models in coding agent harnesses have recently become capable of directly manipulating robot arms for simple tasks. Today, they are far too slow and expensive for any kind of production usage - nearly two orders of magnitude worse than human baselines. We expect this to change quickly. GPT-6 Astra places first in AA-Robotics v0.1, followed by GPT-6.1 Sol, Gemini 4 Argon and Claude Opus 5.5. AA-Robotics v0.1 details: ➤ Our first eight tasks test a range of capabilities: control and dexterity (precise grasping and object handling), spatial reasoning (how objects interact with one another) and adaptability (how models respond to the unexpected) ➤ Models get only brief instructions: how to connect to the robot arm (via a simple HTTP API), the arm's name and how to submit an attempt. They can view the scene through four cameras and write and run code to plan and send movements ➤ Once a model submits an attempt, its end state is graded against the task's pass criteria. A pass scores 100; an incomplete attempt earns partial credit. All attempts are zero-shot Key findings: ➤ The GPT family tops the leaderboard: GPT-6 Astra scores 69, ahead of GPT-6.1 Sol at 65 and Gemini 4 Argon at 55. Claude Opus 5.5 (49) and Claude Fable 5.1 (46) trail ➤ Today’s models are incredibly slow at our tasks, taking ~30 minutes on average to complete each tabletop task ➤ Cost varies widely: GPT-6.1 Sol is the cheapest at $1.93 per task on average; GPT-6 Astra, the most expensive, costs $16.36, more than eight times as much ➤ Compared with a human, today's best-performing frontier language models are ~100x slower and ~10x more expensive More results, clips, and how AA-Robotics v0.1 works follow in the thread below.
