Long-Horizon-Terminal-Bench tests coding agents on 46 terminal tasks that can run for 90 minutes. The takeaway is not that agents are useless. It is that evals need to measure endurance, recovery, and partial progress.
New benchmarks on 5,559 test utterances show Apple's iOS 26 SpeechAnalyzer API achieving 2.12% word error rate - beating all Whisper model sizes while running 3x faster.
Cursor shipped Composer 2.5 in May 2026 - a 1T parameter agentic coding model that matches Opus 4.7 and GPT-5.5 on benchmarks at roughly one tenth the cost. Here is everything you need to know to use it effectively.
New benchmark data shows GPT-5.5 hallucinates 86% of the time when it does not know the answer - versus 28% for the open-weights GLM-5.2. The numbers challenge the assumption that bigger models equal more reliable output.
Fable 5 launched June 9 at 2x GPT-5.5's price with a 22-point SWE-Bench Pro gap. Here is the decision framework for choosing between them.
SWE-Bench has an 81% false-positive problem. FrontierCode replaces it with mergeability as the metric - and the scores are sobering for every AI coding tool on the market.
GPT-5.5 and 5.5 Pro hit the API on April 24. Here is what changes for builders: pricing, agentic tasks, tool-use, and the real benchmarks I ran the day it dropped.
Benchmarks are useful, but frontend work fails in places leaderboards barely measure. Here is how Web Dev Arena turns AI model comparison into a practical UI evaluation workflow.
Anthropic's Sonnet 4.6 narrows the gap to Opus on agentic tasks, leads computer use benchmarks, and ships with a beta million-token context window. Here's what actually changed.
xAI has launched Grok 4, claiming the title of the world's most powerful AI model. With a $300/month Super Grok tier, saturated AMI benchmarks, and a coding model on the horizon, this is xAI's bigge...
xAI launched Grok 3 with 200,000 GPUs, outperforming GPT-4o, Sonnet 3.5, and DeepSeek R1 on reasoning benchmarks. Here is what the hardware, the benchmarks, and the new features actually mean for developers.
