AIOpenAI announced that GPT-6 is being rolled out to all ChatGPT users, alongside a new Intelligent UI. The excerpt provides no further details on capabilities, availability timing, or how the interface works.

AIAnthropic released Claude Haiku 5.5, a small model priced at about a quarter of Haiku 4.5's running cost. Anthropic also halved Sonnet 5.5 cache read prices from 20 cents to 10 cents per million tokens.

AIOpenAI halved its cached-input price compared with GPT-6 Sol. Our measurements show it also handles long prompts faster.

AI…the Index. Compared to the publicly available GPT-6 Sol, the Daybreak Blue model has the largest gains on CyberGym-E2E, which is the benchmark where we observe the most safety refusals

AIArtificial Analysis added trusted-access models to its Cyber Index, and GPT-6 Sol (Daybreak Blue, max) now ranks first. The model is available only through OpenAI's Daybreak program and records no safety blocks across the Index. Its overall score is 32 points higher than the publicly available GPT-6 Sol (max), at a cost of $1.77 per task versus $11.67 for Grok 4.7 (xhigh).

AIBuilt for work where speed and intelligence make a difference: debugging an outage, agents navigating apps, and live experiences where every second counts.

AIAnthropic released Claude Haiku 5.5, priced the same as OpenAI's GPT-6 Luna, with a 1M-token context window. Artificial Analysis scored it 43 on its Intelligence Index, slightly ahead of GPT-6 Luna at 38, but it uses about 3x more output tokens at max effort.

AIArtificial Analysis is adding trusted-access models to its Cyber Index, starting with GPT-6 Sol (Daybreak Blue, max), which is available only through OpenAI's Daybreak program. The model hits no safety blocks across the Index and scores 32 points higher overall than the publicly available GPT-6 Sol (max), with its largest gains on CyberGym-E2E.

Why it matters: The source shows how safety refusals shape cyber benchmark scores, with the trusted-access model's gains concentrated on CyberGym-E2E, useful for comparing guarded and unguarded models.

AIAnthropic has released Claude Haiku 5.5, its cheapest and fastest small model, priced at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100K tokens. It keeps a 1M token context window, up to 128K output tokens, and is generally available on the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry and Claude Platform on AWS. Anthropic reports 72.4% on OSWorld 2.1 (offline subset) versus 15.7% for Haiku 4.5, and the article notes that non-default temperature, top_p or top_k values return a 400 error.

AIOpenAI is releasing a new version of GPT-6 to all ChatGPT users, extending the model beyond text. The post says model and infrastructure improvements were combined to scale it to 1.2 billion users, and it pairs the release with Intelligent UI, which delivers fast, interactive, and visual answers.

Why it matters: The post names the rollout scope and points to model and infrastructure work behind serving the update, which shows how a large consumer launch is being scaled.

AIOpenAI is rolling out GPT-6 with Intelligent UI globally to Plus, Pro, Business, and Enterprise users today, with Free and Go users following starting tomorrow. Plus, Pro, Business, and Enterprise tiers are powered by GPT-6 Sol, while Free and Go tiers use GPT-6 Luna, and both are tuned for everyday conversation. The update applies only to the Chat tab, and the models powering Work and Codex are not changing.

AILiquid AI released d1 with vision support, accepting images, text, or both as inputs. In tests on six real applications, d1 matched or beat GPT-6.1 Sol on four while costing 19x to 200x less than both GPT-6.1 Sol and Claude Opus 5.5. It returns probabilities for yes/no, choice, or score questions in one forward pass, with text decisions in 200 to 300 ms.

AIArtificial Analysis reports that Google's Gemini 4 Argon scores 53 on its Intelligence Index with high reasoning, matching GPT-6 Astra (max) and one point ahead of GPT-6.1 Sol (max). At the current 50% launch discount, its cost per task is $1.99, about 60% of GPT-6 Astra's $3.26, but the discount's end date is unconfirmed and standard pricing would raise it to $3.98. The model is being rolled out to selected users and is not publicly available.

Why it matters: The benchmark compares Gemini 4 Argon's cost per task and hallucination rate with GPT-6 Astra, showing where its value depends on a temporary 50% discount.

AIOpenAI's Sam Altman introduces 6.1 Sol, a model with near-Astra intelligence priced at one fifth of Astra and a 95% cache read discount. The quoted post says ultrafast mode gives 8X speed for Astra today and will come to 6.1 Sol soon.

AIOpenAI says GPT-6.1 Sol is available starting today to all Plus, Pro, Business, Enterprise, and Edu users. The model is offered in ChatGPT Work and Codex, and the post links to OpenAI's introduction page.

AIIt’s more transparent about its limitations and more reliable at respecting user intent and safety constraints.

AIArtificial Analysis reports that GPT-6.1 Sol replaces GPT-6 Sol after seven days and scores 1 point below GPT-6 Astra on the Intelligence Index. At max effort it costs $0.72 per Intelligence Index task, compared with $3.26 for GPT-6 Astra and $1.05 for GPT-6 Sol. Its pricing matches GPT-6 Sol at $2/$10 per million input/output tokens, but it uses about 10-30% more output tokens.

Why it matters: The source compares GPT-6.1 Sol against GPT-6 Sol, GPT-5.6 Sol, and GPT-6 Astra on cost per task and token use, helping readers weigh performance against price.

AIOpenAI introduced GPT-6 Sol and GPT-6 Luna, which build on advances behind GPT-6 Astra. The company says it cut API prices 50% for Sol and Luna compared with GPT-5.6 promotional pricing, passing on caching and inference efficiency gains. Simon Willison notes GPT-6 Luna costs half of GPT-5.6 Luna and calls Luna his favorite model for building product features because of its cost and speed.

AIOpenAI introduced GPT-6 Sol and GPT-6 Luna, which it says bring much of the strength of GPT-6 Astra into faster and more affordable models. The company also reports more efficient caching and inference, with API prices 50% lower than GPT-5.6 promotional pricing.

Why it matters: The quoted announcement names specific pricing and access changes for Sol and Luna, which matter for teams weighing cost against the Astra tier.

AIOpenAI has released GPT-6 Sol and GPT-6 Luna, which it says build on GPT-6 Astra and offer faster, more affordable performance. API prices for Sol and Luna are 50% lower than GPT-5.6 promotional pricing, and Luna now costs $0.10 input and $0.50 output per 1M tokens. The author also notes an earlier 80% Luna price cut at the end of July, with output dropping from $6 to $0.50 within two months.

Why it matters: The source gives concrete API price cuts across two model tiers, making the cost trend across recent releases easy to track for developers.

AIOpenAI announced GPT-6 Sol and GPT-6 Luna, rolling out today in ChatGPT Work and Codex. The rollout covers Plus, Pro, Business, Enterprise, and Edu users.

AIOpenAI's official ChatGPT account says Free and Go users can try GPT-6 Luna in the desktop app, with rollout starting today. The post links to OpenAI's announcement introducing GPT-6 Sol and Luna.

Why it matters: The post names the access tier and platform for the new model, which is the detail readers need to judge whether it applies to them.

AIIt's incredible at keeping consistency while editing images, and SOTA on all image leaderboards. If you've been burned by faces slightly changing when editing with GPT Image 2, give it another try!

AIFireworks AI reports that DeepSeek-V4.1-Flash scores 74.34% pass@1 on DeepSWE at $0.430 per task, close to GPT-6-Astra's 74.12% at $6.524. On Terminal-Bench 2.1 it scores 86.5% against Astra's 87.5% at about 12x lower cost per task, while on HLE it trails Astra alone at 34.52% versus 50.40%. The post also reports that a combined oracle router reaches 54.80% on HLE, and that serverless and dedicated API access is available with US-hosted endpoints coming soon.

AIGPT-VI ASTRA

AIIt does not treat a hard question as one long search. It drafts a candidate, checks every constraint, and goes back for what is still open. 122B MoE. 10B active. On hard search benches it sits next to GPT-5.4. Here is how it works👇

AIIt's also 72% more efficient in GPU usage, so we can provide it at an incredible price. This gives it the best price-performance score in the world. Unbelievable work from the team. So much more to come! Try MAI-Image-2.6-Flash out now!

AIOpenAI researcher Mark Chen announced GPT-6 Astra, which he described as the company's most capable and aligned model yet. He said it can build and test software, work across apps on a computer, and help with open scientific problems. The post also highlights improved computer use compared with Operator and stronger monitoring that can stop potentially unauthorized agent actions.

Why it matters: The post links a named model release to specific capabilities like computer use and aligned agent behavior, giving readers concrete claims to check against the model.

AIOpenAI cut API prices for two GPT-5.6 models, with Luna down 80% to $0.20 per million input tokens and $1.20 per million output tokens. Terra drops 20% to $2 input and $12 output per million tokens. GPT-5.6 Sol gains a Fast mode in the API that offers up to 2.5x the speed for 2x the price at the same intelligence level.

AIjasondeanlee used the double cycle cover prompt to get to 2.28 and with 8 (EIGHT!) hours of further thinking GPT-5.6 got it down to 2.26 and wrote a paper on it:

AIOpenAI has shipped GPT-5.5 Instant to ChatGPT, rolling out to everyone over the next couple of days. The quoted post says the model focuses on factuality, reducing hacks, and improving baseline intelligence, and is significantly less likely to hallucinate.

AIOpenAI released Privacy Filter, a bidirectional token-classification model that detects and masks personally identifiable information in text under the Apache 2.0 license. The model has 1.5B total parameters with 50M active, supports a 128,000-token context window, and can run in a web browser or on a laptop. Users can fine-tune it and adjust precision/recall tradeoffs through preset operating points.

AIOpenAI's Nick Turley announced that GPT-5.3 Instant is rolling out in ChatGPT starting today. The update responds to feedback that GPT-5.2 was sometimes too cautious, over-caveated, and less natural in conversation, with fewer unnecessary refusals, fewer defensive disclaimers, and more direct answers.

AIOpenAI has published weights for a sparse model from Gao et al. 2025, used for qualitative results on bracket counting and variable binding, on Hugging Face under the openai/circuit-sparsity repository. The release includes a standalone Hugging Face implementation that loads the converted model and tokenizer with trust_remote_code and runs sample generation. The project is licensed under Apache License 2.0.

AIOpenAI is introducing GPT-5.2 in ChatGPT, describing it as its most advanced model series for professional work. GPT-5.2 Thinking is positioned for tasks such as building spreadsheets and presentations, writing and reviewing production code, and analyzing long documents. The post says it beats or ties industry professionals on well-specified knowledge work tasks spanning 44 occupations 70.9% of the time on GDPval, and GPT-5.2 Instant, Thinking, and Pro begin rolling out to all tiers, starting with paid plans.

Why it matters: The post links the model's professional-work focus to GDPval results across 44 occupations, showing how the claimed capability was measured.
