#Model release

AITibo, an OpenAI employee, says GPT-6 in Chat is the day's big release and that Codex and ChatGPT Work reached a new high of 40M active users. He also says a banked reset is being loaded into everyone's paid accounts, and the post is part of a three-day series with a Day 2 roundup quoted in it.

AIAnthropic's Claude Haiku 5.5 is much faster and 75% cheaper than Haiku 4.5, which launched October 15, 2025, less than a year earlier. Anthropic describes it as a significant step up over Haiku 4.5 across coding, computer use, and knowledge work.

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.

AIAnthropic's Claude Haiku 5.5 is described as a good Haiku, with a 100k token context window and roughly 10x lower cost than Claude Haiku 4.5. The quoted Claude announcement says it is the cheapest, fastest, and most capable small model Anthropic has released, costing about 75% less to run on average than Haiku 4.5.

AIAnthropic's Claude Haiku 5.5 is now available on Amazon Bedrock and Claude Platform on AWS. According to Anthropic, it is the fastest and most efficient model in the Claude 5.5 family and costs around 75 percent less than Claude Haiku 4.5 for most tasks. The post also covers pairing it with Claude Opus 5.5 as a subagent layer and provides Boto3, Converse, and Anthropic SDK examples for calling the model.

AIChatGPT now includes Intelligent UI, which lets GPT-6 Instant generate interface elements inside chat. The quoted OpenAI engineer says the team aimed to keep HTML's power while making the interface feel fast and native, and that post-training GPT-6 to judge when an interface helps remains an open challenge.

AIGoogle released EmbeddingGemma 2 on Hugging Face, and Paige Bailey called it a step toward open models for open science. The post links the model and cites earlier EmbeddingGemma-based projects, including medical, geographic, oncology, and PubMed embedding models.

AIAnthropic has released Claude Haiku 5.5, a small, fast model for high-volume, cost-sensitive tasks such as summarization, subagents, and browser use. It succeeds Claude Haiku 4.5 with stronger coding and computer use capabilities.

AIOpenAI is rolling out GPT-6 and Intelligent UI in ChatGPT, adding interactive diagrams, calculators, and tools directly inside conversations. GPT-6 can also begin answering while still thinking, and access starts today for Plus, Pro, Business, and Enterprise users, with Free and Go users following tomorrow.

AILiquid AI released two open-weight multimodal decision models, d1-3B and d1-omni-600M, which return probability answers in one forward pass with zero output tokens. d1-3B scores 48.57 on Decision Index v0.2.1 and answers one question in 8 ms on an RTX 4090, while the models are licensed free for commercial use below $10 million in annual revenue.

AIAnthropic's Lydia Hallie says Claude Haiku 5.5 suits mostly reading, small edits, and tool calls that need little reasoning. The quoted @claudeai post introduces Haiku 5.5 as Anthropic's cheapest, fastest, and most capable small model, costing around 75% less to run than Claude Haiku 4.5.

AIAnthropic has released Claude Haiku 5.5, which it describes as the cheapest, fastest, and most capable small model it has released. On average it costs around 75% less to run than Claude Haiku 4.5, and the author says it is 10x cheaper than Haiku 4.5 under 100k tokens. It can be tried with computer use, workflows, and the API.

AIVercel says Anthropic's Claude Haiku 5.5, model ID anthropic/claude-haiku-5.5, is now available on AI Gateway. The company describes it as the fastest Claude model at standard speed, built for subagents and summarization, and the first Haiku to offer effort levels, with ZDR supported.

AIAnthropic's Claude Haiku 5.5 is priced at $0.10 per million input tokens and $0.50 per million output tokens, rising to $0.50 and $2.50 above 100k input tokens. Claude Sonnet 5.5 cache reads have also dropped from $0.20 to $0.10 per million tokens. Cursor points readers to its CursorBench evaluations to compare Haiku 5.5.

AIClaude Code v2.1.293 adds Claude Haiku 5.5 (claude-haiku-5-5), now the default Haiku model on the Anthropic API, with 1M context and pricing of $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K). The release also adds agentType to the subagentStatusLine payload and isDeferred to $.tool.register, and fixes numerous issues including a memory leak in HTTP MCP connections.

AIAnthropic's account shares a link to a page announcing Claude Haiku 5.5. The post itself gives no further details on capabilities, pricing, or benchmarks.

AIAnthropic's ClaudeDevs account states pricing for prompts under 100K tokens at $0.10 input and $0.50 output per million tokens, with cache reads at $0.01. For prompts above 100K tokens, the rates rise to $0.50 input and $2.50 output per million tokens, with cache reads at $0.05.

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.

AIAnthropic introduced Claude Haiku 5.5, which it calls the cheapest, fastest, and most capable small model it has released. On average, it costs about 75% less to run than Claude Haiku 4.5. The post positions Haiku 5.5 for high-volume work alongside Opus handling heavier reasoning tasks.

AIAnthropic has introduced Claude Haiku 5.5, which it describes as the cheapest, fastest, and most capable small model it has released. On average, running it costs around 75% less than Claude Haiku 4.5. The author's own post only announces availability and offers no further detail.

AIAnthropic's Haiku 5.5 is built for high-volume, cost-sensitive work such as summaries and classification. It can serve as a subagent alongside Claude Opus 5.5 and Sonnet 5.5 on coding tasks. It is also fast enough for live customer support and browser use.

AILiquid AI and NVIDIA Robotics announced a collaboration around Liquid AI's models on NVIDIA hardware. The main post is brief and gives no further technical detail or figures.

AIReflection AI and Mistral each unveiled new open-source models this week, aiming to beat other Western open models, though they trail top Chinese and closed systems on prominent benchmarks. Reflection CEO Misha Laskin says the target is regulated industries and governments that cannot or will not use Chinese models. The outcome depends on whether businesses and agencies accept less advanced models for some tasks in exchange for lower cost and more control.
