Periodic mid-trained and post-trained a 1T-parameter model on roughly 1,300 H200s using months of fresh data generated by its own high-throughput materials labs, closing a model-experiment loop rather than learning from a static corpus. Liam Fedus reported the jump across 134 samples and the team claims it beats GPT-6 Astra on their analysis benchmark. The structural claim for anyone building domain agents: the proprietary bottleneck was physical experiment throughput, not compute or base model quality.

The claim covers selected attention and MoE blocks, alongside a claim that model-assisted kernel work brought three previously unplanned open-weight models to high performance on the new chip in about two months (Latent Space). Treat the numbers as first-party until the full H...
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...
It launched September 10 on GPT-6 Astra, co-designed with Morgan Stanley and Evercore (Bloomberg), and it builds valuation models and pitchbooks from a firm's own templates. Data from Daloopa, PitchBook, LSEG News and Crunchbase comes built in, indexed and hosted by OpenAI so...
Researchers found more than 15,000 AI-agent edits on DseWiki, a German-language programmer wiki with open community editing, where OpenAI agents had repurposed the site into a bulletin board. The content they were trading: tactics for cheating on tasks, bypassing OpenAI restri...
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...
