ThursdAI — the weekly AI news podcast hosted by Alex Volkov — has covered 3 Artificial Analysis releases since May 2026, most recently Optima on Aug 13, 2026. Highlights include Endpoint Accuracy Index, Coding Agent Index, Optima. Every entry below has primary-source links and the episode segment where we covered it live, plus key numbers where we have them.
Artificial Analysis launches Optima: private evals from your own traces
Artificial Analysis launched Optima, which builds private evaluations from your own use case and agent traces. Co-founder George Cameron discussed it on the show alongside the three-factor model-selection framework of intelligence, speed, and cost per task.
Endpoint Accuracy Index: the same open weights score 52% to 100% depending on your provider
Artificial Analysis launched an index measuring whether inference providers actually serve the model they claim: GLM-5.2 scores 52% on one provider and 100% on three others with a 5.2x price spread, and some gpt-oss-120b endpoints hit 22% on tool calling versus the reference's 37%. Low scorers produce about half the output tokens per task, pointing at aggressive quantization. v1.0 covers GLM-5.2 (15 providers), gpt-oss-120b (20), and DeepSeek V4 Pro (9), with Kimi K3 next. CoreWeave came in cheapest on gpt-oss-120b at $0.04/M blended with 98% accuracy.
Artificial Analysis Coding Agent Index benchmarks model + harness combos
Artificial Analysis launched the Coding Agent Index, a benchmark that evaluates model and harness combinations rather than models alone. Opus 4.7 in Cursor CLI leads at 61, GLM-5.1 tops the open-weight entries at 53, and costs vary 30x across combos for similar capability.
