However, just in the last week of June, two of the most anticipated models were confirmed almost simultaneously:<strong>Ticket bounced<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">GPT-5.6: From \u201crelease this week\u201d to \u201csee you in mid-July\u201d<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to exclusive news from well-known whistleblower @synthwavedd on June 23, GPT-5.6 has confirmed that it will not be released within June, and the new target time is approximately<strong>mid-July<\/strong>. In the PredictIt prediction market, the probability of GPT-5.6 being released before July 10 is 57%, and before July 13 it is 59% - bettors obviously believe that the delay is a foregone conclusion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no official reason for the delay. However, the technical communities on Reddit and X generally speculate on two points: First,<strong>U.S. AI export controls<\/strong>This may affect the need for additional testing of the export version; secondly, the model itself requires more tuning - there are Codex logs showing that GPT-5.6 is already under internal testing, but the stability is not up to standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is worth noting that OpenAI has been making constant moves in June: it was confirmed on the 9th that it had been secretly submitted<strong>S-1 IPO Application<\/strong>(valued at more than US$852 billion), while leaks of the Bidi-1 voice model are also brewing. The delay of GPT-5.6 may indicate that OpenAI needs to find a balance between \"IPO sprint\" and \"model quality\" in terms of product rhythm.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Gemini 3.5 Pro: DeepMind itself is not satisfied<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Google is also not optimistic. According to Business Insider, Gemini 3.5 Pro has been confirmed to be postponed to<strong>Released in July<\/strong>. What\u2019s even more interesting is that the whistleblower @pankajkumar_dev revealed:<strong>DeepMind team is \"unsatisfied\" with current checkpoints<\/strong>\u2014\u2014The model lacks fresh knowledge in 2026, and exhibits \"lazy\" behavior on complex and long tasks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is in sharp contrast to Google's confident \"See you in June\" at the May I\/O conference. Gemini 3.5 Flash was indeed released as scheduled and performed brilliantly, but the Pro-level flagship model obviously encountered a more difficult quality threshold.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a href=\"https:\/\/claude.ai\" target=\"_blank\" rel=\"nofollow noopener\">Claude<\/a> Sonnet 50% \"Firefighters\"<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the context of both postponements of these two flagships,<strong>Anthropic quietly will<a href=\"https:\/\/claude.ai\" target=\"_blank\" rel=\"nofollow noopener\">Claude<\/a> Sonnet 5 rolls out to enterprise early access program<\/strong>. This is regarded by the industry as a \"transitional solution\" - when Fable 5 is banned due to export controls and Mythos level recovery is far away, Sonnet 5 serves as Anthropic's \"life extension product\" for enterprise customers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Meanwhile, Anthropic released to great fanfare on June 23<strong><a href=\"https:\/\/claude.ai\" target=\"_blank\" rel=\"nofollow noopener\">Claude<\/a> Tag<\/strong>(Slack version of AI colleague) also demonstrated its layout in the direction of \"creating value without relying on the strongest model\" - using product experience to fill the gap, rather than relying on model competitions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary: The AI \u200b\u200bcompetition in 2026 has entered a new stage of \u201cquality first\u201d<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The simultaneous postponement of GPT-5.6 and Gemini 3.5 Pro sends a clear signal:<strong>The pace of releasing cutting-edge AI models is shifting from \"preemptive\" to \"quality first\"<\/strong>. Under multiple constraints such as IPO pressure, export controls, and security audits, the cost of rushing to launch an immature flagship model may be far greater than a delay of several weeks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For users, this means that July may be the real \"AI release month.\" For developers, the current strategy should be more pragmatic - instead of waiting for \"the next strongest model\", it is better to use the existing GPT-5.5,<a href=\"https:\/\/claude.ai\" target=\"_blank\" rel=\"nofollow noopener\">Claude<\/a> Opus 4.7\/4.8, Gemini 3.5 Flash, etc. make products to the extreme.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Want to learn about the latest developments in AI tools as soon as possible? access <a href=\"https:\/\/aidashxp.com\/en\/\">AI Dash<\/a> Check out the most comprehensive comparison and in-depth reviews of AI tools.<\/p>","protected":false},"excerpt":{"rendered":"<p>2026\u5e746\u6708\u539f\u672c\u88ab\u4e1a\u754c\u79f0\u4e3a&#038;#8221 [&hellip;]<\/p>\n","protected":false},"author":0,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[1],"tags":[],"class_list":["post-316","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/posts\/316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/types\/post"}],"replies":[{"embeddable":true,"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/comments?post=316"}],"version-history":[{"count":0,"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/posts\/316\/revisions"}],"wp:attachment":[{"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/media?parent=316"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/categories?post=316"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aidashxp.com\/en\/wp-json\/wp\/v2\/tags?post=316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
