Anthropic enables fine-tuning of Claude 3 Haiku via Amazon Bedrock
Anthropic announced that Claude 3 Haiku can now be fine-tuned through Amazon Bedrock using custom prompt-completion pairs, with general availability reached November 1, 2024. The capability targets specialized business workflows, with Anthropic citing a case study showing classification accuracy improvement from 81.5% to 99.6% and 85% token reduction on a content moderation task. Early enterprise adopters include SK Telecom and Thomson Reuters, both reporting measurable performance gains. Fine-tuning is available in the US West (Oregon) region with text support up to 32K context, with vision fine-tuning planned.

Anthropic introduces computer use capability, upgraded Claude 3.5 Sonnet, and Claude 3.5 Haiku
Anthropic announced three major developments: an upgraded Claude 3.5 Sonnet with significant coding improvements (SWE-bench Verified rising from 33.4% to 49.0%, surpassing all publicly available models including reasoning models), a new Claude 3.5 Haiku that matches Claude 3 Opus performance at Haiku-tier speed, and a public beta of 'computer use' — a capability allowing Claude to control computers by viewing screens, moving cursors, clicking, and typing. Computer use is available via the Anthropic API, Amazon Bedrock, and Google Cloud Vertex AI, with early adopters including Replit, The Browser Company, and Cognition. Both safety institutes (US AISI and UK AISI) conducted pre-deployment testing, and the model was assessed as remaining within ASL-2 under Anthropic's Responsible Scaling Policy.
Anthropic makes Claude 3 Haiku and Sonnet available to US Intelligence Community and AWS GovCloud
Anthropic has made Claude 3 Haiku and Claude 3 Sonnet available via AWS Marketplace for the US Intelligence Community and AWS GovCloud, marking a significant expansion into government deployment. The company has crafted contractual exceptions to its general Usage Policy to permit legally authorized foreign intelligence analysis, including combating human trafficking and identifying covert influence campaigns, while maintaining restrictions on disinformation, weapons design, and malicious cyber operations. The deployment is currently limited to ASL-2 models under Anthropic's Responsible Scaling Policy. Anthropic also notes prior pre-release access to Claude 3.5 Sonnet was provided to the UK AI Safety Institute for pre-deployment testing.
Anthropic Launches Claude Haiku 4.5: Near-Frontier Performance at $1/$5 per Million Tokens
Anthropic has released Claude Haiku 4.5, a small model priced at $1/$5 per million input/output tokens that delivers coding performance comparable to Claude Sonnet 4 at one-third the cost and more than twice the speed. The model surpasses Sonnet 4 on computer use tasks and achieves 90% of Sonnet 4.5's performance on agentic coding evaluations, running 4-5x faster than Sonnet 4.5. Notably, Haiku 4.5 is classified under ASL-2 safety standards—less restrictive than the ASL-3 applied to Sonnet 4.5 and Opus 4.1—and is described as Anthropic's safest model by automated alignment metrics. It is available via the Claude API, Amazon Bedrock, and Google Cloud Vertex AI.
Anthropic releases Claude 3 Haiku, fastest and most affordable model in the Claude 3 family
Anthropic released Claude 3 Haiku, the fastest and most cost-efficient model in the Claude 3 lineup, processing 21K tokens per second for prompts under 32K tokens. The model is positioned for enterprise workloads requiring high throughput and low cost, with pricing enabling analysis of 400 Supreme Court cases or 2,500 images for one dollar. Haiku is available via the Claude API, Claude Pro on claude.ai, and Amazon Bedrock, with Google Cloud Vertex AI support forthcoming.
Anthropic launches Claude 3 model family: Haiku, Sonnet, and Opus
Anthropic announced the Claude 3 model family on March 4, 2024, comprising three models — Haiku, Sonnet, and Opus — in ascending capability order. Claude 3 Opus claims top performance on major benchmarks including MMLU, GPQA, and GSM8K, with near-perfect recall on long-context evaluations (200K context window, 99%+ NIAH accuracy) and new multimodal vision capabilities. The release also highlights reduced unnecessary refusals, a twofold accuracy improvement over Claude 2.1, and Constitutional AI-based safety tuning. Opus and Sonnet launched immediately via claude.ai and the Claude API across 159 countries, with Haiku to follow.
Claude 3.7 Sonnet and Claude Code: Anthropic's First Hybrid Reasoning Model and Agentic Coding Tool
Anthropic has released Claude 3.7 Sonnet, described as their most capable model to date and the first hybrid reasoning model on the market, capable of operating in both standard and extended thinking modes within a single unified model. The model achieves state-of-the-art results on SWE-bench Verified and TAU-bench, with particular strength in coding and front-end web development. Alongside the model, Anthropic is launching Claude Code in limited research preview, a command-line agentic coding tool that can read/edit files, run tests, and push to GitHub. Pricing remains unchanged at $3/M input and $15/M output tokens, with availability across Claude.ai plans, Amazon Bedrock, and Google Cloud Vertex AI.
Anthropic Releases Claude Sonnet 4.6 with 1M Token Context, Improved Computer Use, and Coding Capabilities
Anthropic has released Claude Sonnet 4.6, positioned as a major upgrade over Sonnet 4.5 with improvements across coding, computer use, long-context reasoning, and agent planning. The model features a 1M token context window in beta and is now the default on claude.ai Free and Pro plans at unchanged pricing ($3/$15 per million tokens). Notably, users preferred Sonnet 4.6 over the prior Opus 4.5 frontier model 59% of the time in coding tasks, and the model shows significant gains on OSWorld computer-use benchmarks alongside improved prompt injection resistance. Safety evaluations found no major alignment concerns and rated it as safe or safer than prior Claude models.
Anthropic Releases Computer Use Capability for Claude 3.5 Sonnet
Anthropic has launched a public beta of computer use for Claude 3.5 Sonnet, enabling the model to control a computer by interpreting screenshots and issuing pixel-level cursor and keyboard commands. The model achieves 14.9% on the OSWorld benchmark, roughly double the next-best AI model's 7.7%, though well below human-level performance of 70-75%. Anthropic trained the model on a small set of simple software tools and found it generalized rapidly to broader computer interaction. Safety analysis confirmed the capability remains at AI Safety Level 2, with prompt injection identified as a primary near-term risk.
