OpenAI has released a public beta of a new Decisions API that evaluates text and images and returns typed answers—probabilities, choices, or scores—about 10x faster than its Responses API. The endpoint, POST /v1/decisions, currently supports only the gpt-6-luna model, and requests combine a model, shared input evidence, and a set of named questions. OpenAI says general availability is expected in the coming weeks.
Insta360's Luna Pro gimbal camera matches DJI's Osmo Pocket 4 with a 1-inch sensor, a 20mm f/1.8 lens, 10-bit log capture, subject tracking, detachable display, and up to four hours of battery life. It undercuts the Pocket 4 in some specs, like 4K vertical video versus 3K, but trails in dynamic range and internal storage, with recent testing noting weaknesses in its log footage.
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 new Epoch AI report by Emberson and Roodman finds that the price of achieving a given level of AI performance has dropped roughly 47% per quarter over the past three years, a 13-fold annual decline. The report cites OpenAI's o3, which cost about $0.30 per question to score 75% on GPQA Diamond in January 2025, compared with a much newer model reaching similar scores for a fraction of a cent by mid-2026.
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 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.
According to The Information, Meta is building a new smart glasses model called Luna that drops the built-in camera found in its current lineup. Instead, the device relies on six microphones and a side button to let wearers talk directly to Meta's AI chatbot and its Muse AI agent. The glasses could debut as soon as next week's Meta Connect event in Menlo Park.
Meta is reportedly developing a new line of smart glasses, dubbed Luna, that will not include cameras, according to The Information. The devices, expected to launch in October in Clubmaster and Burbank styles, will feature six microphones and ear-facing speakers so users can talk to Meta's AI assistant via a side button, but will lack the recording capability found in Meta's Ray-Ban glasses.
Meta is reportedly building a camera-less version of its Ray-Ban smart glasses, codenamed Luna, following widespread criticism that the camera-equipped models enabled covert recording and harassment. The new glasses would retain six microphones for voice interaction with Meta's AI assistants but drop the camera entirely, and could debut as soon as next week's Meta Connect conference.
