Artificial Analysis says GPT-6 Sol and Luna score similarly to their predecessors on its Intelligence Index at about half the cost, with the reduction driven by token prices that are roughly 50% lower.
Citing Semafor, Polymarket says Trump is reportedly considering Treasury Secretary Scott Bessent for a new White House “AI czar” role.
Instacart is coming to Muse. It says people will soon be able to connect Instacart, turn “Taco Tuesday” into a cart from a favorite store, and check out for home delivery.
Glean says Claude Opus 5.5 cuts token costs by 50% versus its predecessor on Glean's own evaluations, and that GPT-6 Luna and GPT-6 Sol each cost 50% less than their predecessors.
Luna is available on all plans and the API; the $10 GOAT plan is given as an example with about 30,000 requests and about 1.5 billion tokens. Sol is available on the Pro and Max plans and the API.
Databricks is making OpenAI’s GPT-6 Sol and GPT-6 Luna and AnthropicAI’s Claude Opus 5.5 available to its customers. Databricks says the GPT-6 models perform strongly at lower cost with a higher Pareto frontier on OfficeQA Pro, and that Claude Opus 5.5 improves cost efficiency on enterprise document parsing.
Anna Tong reports a raise of more than $100 million and says annual recurring revenue grew from $7 million to $500 million in 1.5 years at a business she describes as selling data to AI labs.
OpenAI Developers says applications can select reusable prompt prefixes with explicit cache breakpoints, change reasoning effort and tool availability while preserving cached context, and prewarm shared context so responses start sooner.
Higher default cache-hit rates let more GPT-6 input tokens receive cached-input discounts of up to 90%. OpenAI Developers says the change helps agents run faster and cost less.
A new Prompt Caching Dashboard on platform.openai.com tracks cache-hit rates. A diagnostics API identifies changes that prevented cache reuse and estimates how many tokens were affected.
Users can authorize the agents to research markets, pay for data, and execute trades, according to Polymarket.
In ComfyUI, encoding is up to about 2.2 times faster and decoding is about 1.4–2.7 times faster. ComfyUI reports a 1344×768, 129-frame round trip falling from 24.3 seconds to 12.7 seconds.
Arena.ai scores SpaceXAI’s Grok 4.7 (xHigh) at 1,632 points, 16 points and six places above Grok 4.6 (High). Simulations and Consumer Product also move up.
According to Polymarket, the integration will let AI agents help users plan travel, including finding and booking hotels.
Perplexity post-trained a Computer model to learn from its own errors using hint-guided self-distillation. It said the 21.2% reduction was relative to an earlier checkpoint.
The app is now available on the new Pika, Pika’s AI creative platform. It keeps the original video’s timing, motion, and narrative while replacing the selected elements.
Sluicebox’s AI supplier agent Lucy uses NVIDIA Nemotron 3 Ultra to collect and check supplier data while engineers design a data center’s carbon footprint. In Sluicebox’s tests, Nemotron improved accuracy, cut costs by 51–80%, and returned responses up to 2x faster.
The release also includes transcript search, mouse copy, an F8 voice toggle and /voice settings, plus a /usage dashboard for tokens, plugins, and skills.
Artificial Analysis finds no single open-weight text-to-speech model ahead on all nine new language leaderboards. Leadership is split among Higgs Audio V3 TTS, OpenAudio S1 Mini, Voxtral TTS and Breeze TTS 2.
Artificial Analysis has extended the Controlled Voice Arena with separate text-to-speech leaderboards for Japanese, Mandarin Chinese, Hindi, Spanish, German, French, Portuguese, Vietnamese, and Arabic. Rankings use native-language prompts, standardized cloned voices, and preference votes from first-language speakers.
