It accepts text, JSON, or images and returns typed answers with probabilities, priced at $0.02 per million input tokens with free output. Perplexity says it scores highest on Hugging Face's new Decision Index 0.3 benchmark and costs half as much as v1.

AIAnthropic has released Claude Haiku 5.5, priced at $0.10 input and $0.50 output per million tokens up to 100,000 tokens, matching GPT-6 Luna. Beyond 100,000 tokens the price rises to $0.50 and $2.50, and the author found the new tokenizer uses about 1.25x as many tokens as Haiku 4.5 on the same long prompt. The model cannot disable reasoning and defaults to medium effort.

AIAnthropic's Claude Haiku 5.5 is now generally available in GitHub Copilot, a lightweight model built for fast, high-volume work such as subagents, quick edits, and terminal tasks. GitHub's early testing found it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps. It can be used in the GitHub Copilot app, CLI, or @code.

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.

AIGPT-6 with Intelligent UI begins rolling out globally in the ChatGPT Chat tab for Plus, Pro, Business, and Enterprise users today. The rollout expands to Free and Go tiers starting tomorrow. Plus, Pro, Business, and Enterprise get GPT-6 Sol, while Free and Go get GPT-6 Luna.

AIMatt Shumer says a setup pairing Opus or Sonnet with Haiku sub-agents is very likely the new alpha and that he plans to try it. The quoted Anthropic post introduces Claude Haiku 5.5 as its cheapest, fastest, and most capable small model, costing around 75% less to run than Claude Haiku 4.5.

The model is billed at provider list pricing under usage-based billing and is available to Copilot Pro, Pro+, Max, Business, and Enterprise users.

AIGoogle says users are already testing its newest image generation model, Nano Banana 2.1, and shares examples of the early results. The post provides no benchmark scores, pricing, or capability details.

AIClaude 5.5 Haiku is now available in OpenCode and Go. The post does not give further details about features, pricing, or availability limits.

AISubscribers to Claude's Max plan can claim monthly API credits: $100 for the $100 tier and $200 for the $200 tier. The credits work for any Claude model and can be used in the user's own apps and other agents. The author argues that bundling monthly API credits alongside a broad model lineup will make it hard for other model companies to compete.

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 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.
