A writer used OpenAI's GPT-6 Sol model to teach a virtual simulation of Pollen Robotics' Microduck robot to walk around and identify a bengal cat, with plans to make it dispense treats via a 3D-printed head attachment once a physical unit ships. The process reportedly took only a few hours, compared to what the author says would have previously taken weeks. Separately, UC Berkeley professor Ken Goldberg and students have explored using OpenAI's Astra model, released last September, for generating the detailed 3D simulations needed to train robots.

Ultramarine 1 Flash is a new model priced at $0.13 per task on internal benchmark PI Knowledge Work, which the company says correlates strongly with the Artificial Analysis Intelligence Index. It is built on GLM-5.3 Flash and generates 6.5% fewer tokens than that base model while outscoring Claude Fable 5 (max) and GPT-5.6 Sol (max), which cost $8.19 and $2.09 per task respectively. Pricing on the Ultramarine API is $0.15 per million input tokens, $0.03 for cached input, and $0.50 for output.

Microsoft has released Microsoft-Decision-1, a model built specifically for decision-scoring tasks like routing, classification, prioritization, verification, and workflow control. It is available now through Microsoft Foundry, with OpenRouter access coming soon. Microsoft reports the model topped a 36-benchmark comparison covering nearly 150,000 questions, running 4.5 times faster than the runner-up, Quyet-1.0-Large, and 35 times faster than GPT-6 Sol.

OpenAI has launched GPT-6.1 Sol as part of its DevDay announcements, positioning it as a lower-cost alternative to its flagship GPT-6.1 Astra model. The company says Sol performs comparably to Astra on coding, professional Q&A, document handling, computer use and research tasks, at roughly one-fifth the cost. OpenAI also reports that Sol's rate of factual errors in lower-effort responses dropped from 11.4% with GPT-6 Sol to 7.7% with the new version.

OpenAI announced it will reopen its $200 Pro subscription to new subscribers, alongside a change to how usage is calculated that effectively halves the equivalent API spend compared to the previous version of the plan. The company says it will not reintroduce a prior 5-hour usage limit, and plans to add new subscription features, not yet detailed, that won't count against usage limits. OpenAI also noted it recently cut prices on its GPT-6 Sol and GPT-6 Luna models by 50%.

A researcher describes early experiments using the newly released GPT-6 Sol and Opus 5.5 models to go beyond routine transcription work and attempt to actually solve open historical problems, including tracing alchemical knowledge and decoding 17th century letters. The author outlines criteria for which historical puzzles are 'tractable' for AI, such as codebreaking tasks, citing an example of an AI model decrypting a 1941 German army communication.

OpenAI launched GPT-6 Sol and GPT-6 Luna, positioned as cheaper, more accurate successors to GPT-5.6 Sol and Luna, with API costs cut by 50%. OpenAI says GPT-6 Sol outperforms Claude Opus 5 at roughly 9% of its cost and matches Claude Fable 5.1 on coding tasks at lower cost, while making about half as many errors as its predecessor. Both models are rolling out today in ChatGPT Work and Codex for Pro, Plus, Business, Enterprise, and Edu users, with Luna also available to Free and Go plan users in the desktop app.

Anthropic released Opus 5.5, an update to its flagship coding and knowledge-work model, while OpenAI released GPT-6 Sol and Luna, updates to its mid-tier and smaller efficiency-focused models. Anthropic says Opus 5.5 cuts token pricing by 20%, cuts cache-read costs by 60%, and runs over 30% faster than its predecessor, while benchmarks from Anthropic show it modestly outperforming OpenAI's recently released GPT-6 Astra on coding tasks.

Anthropic released Opus 5.5, an update to Claude aimed at enterprise tasks like coding, financial analysis and business work, claiming better agentic coding benchmarks than GPT-6 Astra and reduced token pricing compared to Opus 5. OpenAI simultaneously released GPT-6 Sol and GPT-6 Luna, cheaper successors to GPT-5.6 that the company says cut factual errors roughly in half and match rival Fable 5.1's coding performance at lower cost.

OpenAI launched GPT-6 Sol and GPT-6 Luna, follow-ups to its 5.6 models and companions to the recently released GPT-6 Astra, aimed at giving businesses and developers Astra-level capability at lower cost with higher usage limits. Anthropic simultaneously released Claude Opus 5.5, which it says matches Fable 5.1's performance while cutting costs nearly 40% compared to Opus 5, and calls its most aligned model yet.

OpenAI has rolled out two new GPT-6 tier models, Sol and Luna, to Codex and ChatGPT Work following its earlier release of the flagship GPT-6 Astra model this month. Both models use fewer tokens than their GPT-5.6 equivalents, with Sol aimed at complex coding and agentic tasks and Luna suited to high-volume, focused work. The rollout covers Plus, Pro, Business, Enterprise and Edu accounts, with Free and Go users able to access Luna via the desktop app, though Enterprise admins must enable access.

OpenAI has updated its smaller GPT-6 models, Sol and Luna, following this month's launch of the flagship GPT-6 Astra. The company says API access to the new Sol and Luna models costs half as much as the previous 5.6 series, citing gains in caching and inference, and claims GPT-6 Sol makes roughly half as many factual mistakes as its predecessor while also reducing coding errors.
