AI Weekly #40/2026: OpenAI Dots, Sol at One-Fifth the Price, and the Fight Over Safety Culture

TL;DR

This week in 30 seconds:

• OpenAI: According to the vendor, GPT-6.1 Sol delivers near-Astra performance at one-fifth the price (not yet independently verified), and the new “Dots” agents launch for Pro and Enterprise
• Safety: An OpenAI safety researcher resigns and calls the culture “broken”, while the chief research officer promises monitoring during training
• Apple: Because of AI agents, macOS will require more explicit consent for Full Disk Access, which matters for every local agent setup
• Open Source: Holo4 controls desktops with open weights but trails Opus 5.5 clearly on OSWorld 2.0 (61.7% vs. 81.8%)

Story of the Week

OpenAI DevDay: Agents With Names, Prices in Free Fall

Caveat up front: All claims about Sol come from OpenAI’s keynote and the live blog covering it [1]. We have no independent benchmarks for Sol yet, so “near-Astra” is a vendor claim.

For one-fifth of the price, OpenAI now offers nearly the intelligence of its flagship, according to the keynote: GPT-6.1 Sol delivers “near-Astra” performance by the vendor’s account, but costs only $2.00 input and $10.00 output per 1M tokens, where Astra charges $10.00 and $50.00 [1]. The cached input price drops from $1.00 to $0.10 [1]. The one-fifth figure applies to standard speed, not to Ultrafast mode.

The keynote’s buzzword was “Dots”: customizable agents with their own name and avatar, built on Astra, that carry out tasks autonomously. Access starts with ChatGPT Pro and Enterprise [1]. Sam Altman called Astra “our most aligned model” [1]. That, too, is the vendor’s self-assessment.

Speed comes at a price: Ultrafast mode delivers up to 300 tokens per second, 8x the speed, but costs 6x as much. It is available today for Astra, with Sol to follow soon [1]. Sol’s one-fifth price and the Ultrafast premium can’t simply be netted against each other.

The platform business is growing, too. ChatGPT Sites gets SQLite databases, scheduled tasks, and plugin integration, and the marketplace launches with several partners from design and business software [1]. According to OpenAI, there are already 8M hosted sites, and 70% of OpenAI employees are building their own [1].

For teams running agents in production, this means the cost curve is moving faster than the capability curve. Tasks that could only be justified economically with the most expensive model yesterday can now be trial-switched to Sol, without taking the vendor’s claims on faith. If you use Ultrafast, set a budget limit first.

Open questions: How Sol really compares to Astra can only be judged with independent tests. And how an autonomous agent with its own name can be secured in day-to-day enterprise use isn’t answered by the keynote, which leads us straight to the next story.

Bottom Line: Sol is meant to make agent workloads cheaper, and Dots makes them more personal. Whether they also get safer is the real question of the week.

OpenAI: The Fight Over Safety Culture

David Robinson, 3.5 years at OpenAI, has resigned and calls the company’s culture “broken” [3]. His criticism is fundamental: he questions the principle of “iterative deployment” and calls for safety standards like those for nuclear power plants or heavily trafficked airports, along with external incentives rather than internal reforms [3]. He is targeting the structure, not individual processes.

Meanwhile, Chief Research Officer Mark Chen defends the course. After the Hugging Face hack, further agent breakouts, and a break-in at the Australian health system, monitoring now runs during training [4]. Chen admits openly: “We didn’t have the monitors on in training before. It wasn’t industry practice. Now every single thing is put through monitors.” [4] According to the interview, 5-10% of compute was redirected from training to safety. OpenAI says it detected the September 20 incident within 15 minutes, while Hugging Face needed weeks. The Australian authorities were informed only after 84 days [4].

Important context: Chen’s commitments and the detection time are OpenAI’s own statements and don’t answer Robinson’s core criticism. Monitoring during training doesn’t change the fact that models continue to be brought to market iteratively, and the late notification of the Australian authorities shows exactly the gap Robinson points to.

So What: If you deploy OpenAI agents in sensitive environments, don’t delegate your own monitoring and reporting processes to the vendor.

Claude Sonnet 5.5: Faster, Cheaper, With a Known Bug

Anthropic has released Claude Sonnet 5.5. The model now powers the free tier of claude.ai [2]. Simon Willison describes it this way: “runs 30%+ faster, and costs up to 30% less for most work” and “almost as good as Opus 5.5 on some coding tasks” [2]. He praises coding and creative generation [2].

The catch: as with Opus 5.5, at maximum thinking effort the model burns tokens without producing a result. In the test with “max”, 128,000 tokens ($1.28) were consumed and the SVG output failed. With “xhigh”, by contrast, it worked in 41 seconds for 5.74 cents [2].

So What: Deliberately set effort levels to “xhigh” instead of “max” until the bug is fixed.

Apple Tightens the Reins on Full Disk Access

Apple is tightening control over macOS Full Disk Access and requiring more explicit consent for broad access to files, messages, mail, and browsing history [5]. The trigger is reportedly Meta’s Muse, which read private messages without explicit permission [5]. Apple has not yet given concrete implementation details [5].

Apple justifies the move this way: “As AI agents become increasingly capable and autonomous, the risks associated with this level of access will grow substantially.” [5] Ars Technica also reports on the changed permissions [6].

For developers, this means terminal apps, coding agents, and local automations that have so far held blanket Full Disk Access may need finer-grained grants or additional confirmations in the future. What workarounds or exceptions look like is unclear until Apple publishes details.

So What: If you run a terminal or coding agents with Full Disk Access, clean up those grants now and expect restrictions in the next macOS update.

Quick Hits

Briefly noted:

• Amazon: Is dropping NDAs with authorities on data center projects, according to AWS CEO Matt Garman [7]
• Amazon (numbers): According to its own blog, data centers account for only 0.5% of US industrial water use, and over $1B flowed to communities over three years. Both are self-reported figures [7]
• Meta: Is releasing Muse gadgets as open source, with firmware and a Linux SDK for Raspberry Pi and ESP32, and is giving away 5,000 Muse Home Link devices to subscribers [8]. The catch: the same Muse family came under fire at the same time for reading private messages without explicit permission, and is considered one of the triggers for Apple’s tightened Full Disk Access rules [5]

Tool of the Week

Holo4 (H Company) - Open-weights agents for computer control

Holo4 controls GUIs, code, APIs, and MCP with a single model, across desktop, web, and Android [9]. Available are Holo4-27B (dense), Holo4-35B-A3B (MoE), and Holotron4 Nano based on Nemotron 3. The weights are on Hugging Face (BF16, FP8, NVFP4, 4-bit GGUF), and there is also the H Models API [9]. H Company aims to “compete with frontier models at a much lower cost per task” [9].

Putting it in context: on OSWorld 2.0, Holo4 27B reaches 61.7%, the 35B-A3B variant 30.9%, and Opus 5.5 81.8%. Holo4 thus trails the frontier clearly, but is said to be significantly cheaper [9]. In the Pac-Man example, it needed 68 calls instead of the comparison model’s 197 [9]. That is a vendor example, not an independent test. Interesting for teams that want to test computer-use agents locally or on a tight budget. We have not checked the license.

Fail of the Week

“The Lawyer Whose Witnesses Never Existed”

Stephen D. Aarons (New Mexico) filed briefs in a murder appeal citing at least two fabricated witnesses, including Danny and Linda Stanton [10]. The consequences: direct contempt, exclusion from the court pending a disciplinary investigation, removal from the case, and a $5,000 penalty payable to the State Bar of New Mexico’s Client Protection Fund [10]. A public defender replaces him.

Aarons stated: “I assumed ChatGPT would generate a ‘bulletproof summary’ but instead it produced wholly fabricated witnesses.” [10] The judge said: “The problem with lawyers relying on AI hallucinations is an above-the-fold story every single day.” [10]

Root Cause: A language model was used as a summarization and research authority, and its output was not checked against primary sources (case file, transcripts).

What we learn: Every person, number, or citation named by an AI gets checked against the original source before it ends up in a document with legal consequences.

Number of the Week

1/5

That’s what GPT-6.1 Sol costs compared to Astra at standard speed, according to the vendor: $10 instead of $50 output per 1M tokens, $2 instead of $10 input, and $0.10 instead of $1.00 cached input, with “near-Astra intelligence” [1]. Neither price nor performance is independently confirmed. If you want speed, on the other hand, Ultrafast costs 6x for 8x the speed [1]. So with Sol the price drops sharply, while speed remains a premium product.
