Three points behind GLM-5.3 at 60, tying GPT-5.6 Terra and Muse Spark 1.2, at $0.09 per task against $0.68 for GLM-5.3 max (Latent Space). It burned 149M output tokens to run the index, of which 134M were reasoning tokens, more than Kimi K3 at 133M or Qwen3.8 2.4T A95B at 136M at comparable scores. The economics come from $0.15/$0.50 per million in and out, not token frugality. Budget in dollars, not tokens. Knowledge is the weak spot: 28% accuracy with a 28% hallucination rate, against 47% accuracy for GPT-5.6 Terra, while Terminal-Bench v2.1 reaches 84.3%.

For about a year, "run your agent locally" meant accepting a model that couldn't reliably call a tool twice in a row. That excuse is gone. Meta Superintelligence Labs published Muse Glimmer today: a 29.6B dense causal transformer, 52 layers, 6,656 hidden dim, with a ~1.8B ViT-...
OpenAI shipped GPT-5.5 on April 23, six weeks after 5.4. The capability jump is real: 82.7% on Terminal-Bench 2.0 vs Claude Opus 4.7's 69.4%. The Pro tier nearly doubles Opus 4.7 on FrontierMath Tier 4 at 39.6% vs 22.9%. It uses 40% fewer tokens on Codex tasks while matching 5...
xAI shipped it August 12 with a 500K context, February 2026 cutoff, $2/$6 per million. It scored 61 on the Artificial Analysis Index, tying GPT-5.6 Sol Max, one point behind Fable 5 Max. The number that got 334 points and 381 comments on HN is from Artificial Analysis's teardo...
This is the other half of the Fable 5 story, so read them together. While the best coding model in the world is uncallable, an open-weight one quietly posted frontier-adjacent numbers. Per Tom's Hardware, independent benchmarks for the MIT-licensed GLM-5.2 (744B params, 40B ac...
You can't sign up for the best coding model OpenAI has ever built. You have to be approved. By the federal government. One customer at a time. OpenAI previewed GPT-5.6 'Sol' on June 26, and the capability story is real: it's a three-model family (Sol the flagship at $5/$30 per...
I don't care that Grok 4.5 ranks #4. I care that it resolves a SWE-Bench Pro task with an average of 15,954 output tokens where Opus 4.8 spends 67,020. That's a 4.2x efficiency gap, and it lands straight in my monthly bill. SpaceXAI launched Grok 4.5 on July 8, a roughly 1.5T-...
