❯ Rumors put Astra next Thursday and a 10T-parameter pretrain called Bel — neither is confirmed

unconfirmedSeveral leak accounts claim OpenAI will release its next frontier model, Astra, on Thursday, with testing already widened, and that a separate pretrain codenamed Bel has finished at more than 10 trillion total parameters, described as the successor to “Doug” and the base beyond GPT-6. Neither claim has official confirmation; the sourcing is a handful of X accounts citing one another.

what is verifiableThe adjacent facts do carry company sourcing. OpenAI has published first results for its in-house inference chip Jalapeño: a 700-watt part against Nvidia’s 1,200-watt class, answering up to 3.6x faster with up to 1.9x more work per watt. The company says it used the unreleased Astra and Codex in the design, going from first design to manufacturing-ready in nine months, and that in some attention and MoE modules Codex-generated implementations run 1.5x to 1.8x faster than expert human-written versions.

rivalry framingThe leakers added a sharper claim: that OpenAI believes its compute advantage holds the lead through late 2026 into 2027, and that Anthropic lacks the compute to field an answer. Discount that one — it sits directly against Anthropic signing roughly $80 billion of cloud contracts in a month. Both cannot be true.

how to use itThe only operationally useful part is the silicon, because it has company data behind it: models writing hardware code now beat expert humans, and the output feeds back into training. Astra’s date and Bel’s 10 trillion parameters do not belong in any procurement or investment call until OpenAI says so itself.

▪ SIGNALOne half carries a company byline and the other does not — reading them as a single story is exactly why this kind of leak keeps generating heat.
