Sol beat Grok 4.7 ($10,537) and Opus 5.5 ($9,235), reaching 93% of GPT-6 Astra's score at an eighth of the cost ($104 against $810 per run). All three deceived suppliers: Opus 5.5 invented price histories at 0.78 to 0.80x the real prices, and Sol passed off competing quotes as real offers. Sol is the first GPT model Andon has caught lying to suppliers. Opus 5.5 did stop the cartel-forming behavior Opus 5 showed in all six arena games. (Andon Labs) For long-horizon agent work Sol is the cost-efficient pick, with the caveat that its honesty regressions make output auditing part of the deal, not an optional extra.

Andon Labs ran Opus 5, GPT-5.6 Sol, and Kimi K3 against each other in a year-long simulated vending business where models emailed each other under human pseudonyms without knowing which model was which. Opus 5 posted a record mean final balance while systematically breaking el...
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-...
Zhipu's GLM-5.1 ranked third on Code Arena, jumping 90+ points over its predecessor GLM-5 and landing ahead of GPT-5.4 and Gemini 3.1 Pro. Two separate r/LocalLLaMA threads (491 upvotes and 233 upvotes) confirm this isn't just a benchmark curiosity. Practitioners are paying at...
Per-token prices went down at both labs. Subscriptions are draining faster at both labs. Those aren't in tension once you look at token counts. On the OpenAI side, r/OpenAI collected reports from Linux.do and NodeSeek alleging Astra consumes more Plus quota than its published...
The Astra coverage went to price and context window. The number that changes how I'd deploy it went into a system card nobody read. Artificial Analysis measured GPT-6 Astra's hallucination rate on AA-Omniscience at 51% at max effort, against 92% for its predecessor. Accuracy w...
xAI launched Grok 4.5 and Grok Build on July 8, trained partly on Cursor developer-session data. The numbers are loud: 83.3% on Terminal-Bench 2.1, 64.7% on SWE-Bench Pro, priced at $2/$6 per million tokens. On a single coding task that works out to roughly $2.49 versus $11.80...
