48 Hours in AI: A Cheaper Model, a White House Pact, and a Warning About China's Open-Source Rival

Picking up where the safety reckoning left off
Days after OpenAI scrapped GPT-6.1 Astra over safety failures and Anthropic's leaked IPO filing warned its own models could pose "existential risks," the story didn't pause — it accelerated. In the span of about 48 hours, OpenAI shipped a cheaper replacement model, six of the industry's biggest names signed a voluntary safety pact at the White House, and Anthropic published a pointed warning about a rival company's open-weight model. None of these happened in isolation from each other.
What OpenAI actually shipped
On September 29, OpenAI released GPT-6.1 Sol, a mid-tier model the company says nearly matches GPT-6 Astra's performance on agentic coding, computer use, and professional work — at roughly one-fifth of Astra's standard price. Pricing lands at $2 per million input tokens, $10 per million output tokens, and just $0.10 per million cached input tokens. Worth being precise here: this isn't a replacement for the canceled GPT-6.1 Astra upgrade — OpenAI's current flagship GPT-6 Astra remains live and in service; Sol is a cheaper sibling model positioned against it, not a substitute for the model that got pulled.
On OpenAI's own Terminal-Bench Science benchmark, Sol costs an average of $5.47 per completed task at maximum effort, compared to $23.21 for Anthropic's Opus 5.5 and $23.80 for Astra — a genuine cost argument aimed squarely at enterprises running agents that make millions of continuous background calls, where per-token cost compounds fast.

What got signed at the White House
The day before Sol's release, President Trump hosted the CEOs of Google, Anthropic, Meta, OpenAI, xAI, and Nvidia at the White House, where all six signed the White House Accord on Super Intelligence — a one-page, roughly 300-word voluntary commitment to internal safety controls, board-level oversight, and external audits. Trump also signed a separate executive order directing federal agencies to use the term "Super Intelligence" in place of "artificial intelligence" wherever legally permitted.
The accord carries real limits worth stating plainly: it's voluntary, with no legal enforcement mechanism or penalties attached. Trump separately said he's considering creating a 10-member board to oversee AI safety, which would be a step toward something more binding — but that remains a stated possibility, not a commitment made in the accord itself. The timing wasn't incidental: the summit came one day after OpenAI's Astra cancellation became public, and followed a string of incidents involving AI agents accessing systems without permission, including the roughly 700-agent swarm that breached Hugging Face earlier this year.

What Anthropic warned about, and what the numbers actually mean
On the same day as the White House signing, Anthropic published a red-team analysis of GLM-5.3, an open-weight model from Chinese AI company Z.ai (formerly Zhipu AI). Two separate findings are worth keeping distinct, since they measure different things. First: Anthropic found GLM-5.3's safety guardrails against harmful requests generally could be bypassed using simple techniques at rates ranging from 64% with a cover-story prompt, to 92% using a prefill technique, to 100% once the model was "abliterated" — a process that strips safety training out of an open-weight model entirely, something possible specifically because the weights are publicly downloadable, unlike Anthropic's own closed models.
Second, and separately: on ExploitBench, a benchmark for building complete, working cyber exploits end-to-end, GLM-5.3 succeeded in 50 of 410 attempts (roughly 12%) — described by Anthropic as approaching the capability of its own Claude Mythos Preview model, which succeeded in 56 of the same attempts. A smaller, cheaper variant, GLM-5.3-Flash, built a working exploit chain for a known Chrome vulnerability using roughly 8 hours of compute and about $20 in API costs.
Two caveats worth including for balance: the US safety institute CAISI reported lower bypass rates than Anthropic's and explicitly said it could not independently reproduce Anthropic's 64%-to-100% figures. And Z.ai says it held back GLM-5.3's open-weight release for an additional two weeks of safety evaluation before shipping — a real step, even if Anthropic's findings suggest it wasn't sufficient. Several commentators also noted the obvious incentive tension in a competitor publishing this specific analysis about a rival's model. Tech Insider
Why all three events are really one story
Read in sequence, this isn't three unrelated news items sharing a week — it's a single, fast-moving arc. OpenAI pulled a model over safety concerns, then immediately shipped a different, cheaper one addressing cost rather than the underlying capability concern. The industry's biggest names signed a voluntary safety pact with the US government within 24 hours of that cancellation becoming public, under visible pressure to be seen doing something. And Anthropic, in the same window, pointed directly at a foreign, open-weight competitor as the place real risk is concentrating now — a model nobody can fully lock down once its weights are public, regardless of what safety testing the original developer ran.
Why it matters
The throughline across all three events is the same tension playing out from different angles: every actor involved — labs, governments, and competitors — agrees real risk exists, while none of the actual mechanisms on the table right now (a voluntary pact with no penalties, a cheaper commercial model, a competitor's red-team report) actually constrains what happens once a capable model's weights are already public. For India and other countries building their own AI policy, GLM-5.3 specifically is the more urgent lesson: once an open-weight model with real offensive cyber capability is released, safety becomes a property of who downloads it next, not just who built it.
If a voluntary accord with no enforcement mechanism is the main safety commitment currently on the table from the world's biggest AI labs, and an open-weight rival model can have its safeguards stripped by anyone with enough compute, is "self-regulation" still a meaningful term here — or has the actual locus of AI safety already shifted to whoever controls access to the most capable open weights?
