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.
