A 369-upvote r/OpenAI post argues Sol is much less thorough than 5.6 Sol while being priced like 5.6 Terra, leaving a gap between Sol and the compute-heavy Astra. The top reply says they reverted to 5.6 Sol for most tasks. (thread) Read this next to the Andon Labs result and the two aren't in conflict: Sol is cost-efficient across a long horizon and thinner on any single hard task.

He argues the gains most likely come from training recipe and data, noting OpenAI's chief scientist saying compute depth stays within a factor of two of GPT-4. He walks through weight-reused looped stacks back to Universal Transformers (2018), with Nanbeige4.2-3B applying 22 b...
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...
67 on coding against Fable 5.1's 70 in Claude Code. Astra does post a 2% hallucination rate against 9.4% for GPT-5.6 Sol, and 0% scope violations against 48%. Per-task cost runs the other way, $4.72 for Astra against $9.18 for Fable 5.1 at identical $10/$50 list pricing, and A...
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...
Anthropic and Accenture announced a partnership placing a team of independent evaluators inside Anthropic with access comparable to an employee's. Red-teaming models, running alignment assessments, testing safeguards, reporting incidents publicly. Each company expects to inves...
In a session with Marc Benioff uploaded September 16, Altman laid out a ladder: GPT-5.5 "maybe as good as an average math professor," GPT-5.6 "a top one or two percentile math professor," Astra "a little bit better than that," and an unreleased internal model beyond Astra at t...
