Anthropic Launches Claude Haiku 5.5, Cheaper and Faster AI Model
Confirmed
In Short: The release of Claude Haiku 5.5 is part of Anthropic’s strategy to push its AI business deeper into the cost-sensitive enterprise market, offering a faster and cheaper model designed for routine coding and business tasks.
Anthropic has released Claude Haiku 5.5, the latest iteration of its AI model, which is now the fastest and most affordable option available. The new model costs around 75% less to run than its predecessor, Claude Haiku 4.5, and is designed to handle high-volume, cost-sensitive tasks.
According to 9to5Mac, the company is halving the price of Claude Sonnet 5.5’s cache reads, making Sonnet 5.5 run around 20% cheaper on most agentic work. This move is part of Anthropic’s strategy to support users in building new agents and applications on the Claude Platform.
Claude Haiku 5.5 is positioned as the smallest and cheapest of Anthropic’s three main models, alongside Sonnet (medium size and price) and Opus (largest and most expensive). The new model costs $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100,000 tokens.
The release of Claude Haiku 5.5 comes less than a week after the launch of Claude Opus 5.5 and about a year after the previous Haiku model upgrade. The company is also cutting Sonnet 5.5’s cache-read price in half, from $0.20 to $0.10 per million tokens.
In a press release, Anthropic stated that the new model delivers similar levels of coding performance as Claude Sonnet 4, but at one-third the cost and more than twice the speed. Curtis Allen, a principal engineer at Slack, noted that Sonnet 5.5 outperformed Sonnet 5 on nearly all of Slack's offline Slackbot evaluations, finishing in fewer steps and with about 14% fewer output tokens.
Claude Haiku 5.5 is designed to reliably handle quick and repetitive workloads such as summaries, compactions, database queries, and classification requests. It pairs well with Opus 5.5 and Sonnet 5.5 as a subagent on coding work and works especially well for speed-sensitive tasks like live customer support and browser use.
The new model’s performance improvements and cost reductions reflect Anthropic’s commitment to transparency and incremental gains. According to Anthropic’s official announcement, the upgrade is described as a modest but tangible improvement on its predecessor.
Anthropic’s rapid release of new models continues despite calls for a slowdown in AI innovation. The company has been moving quickly, with the latest release following a $65 billion Series H funding round led by Altimeter Capital, Sequoia Capital, and other major institutional investors.
The release of Claude Haiku 5.5 is part of Anthropic’s strategy to push its AI business deeper into the cost-sensitive enterprise market, offering a faster and cheaper model designed for routine coding and business tasks.
As with all new AI model releases, the actual performance of Claude Haiku 5.5 in real-world applications will need to be evaluated to determine its effectiveness and impact.
Anthropic’s rapid commercial expansion continues as the company balances the need for innovation with growing scrutiny over the risks of increasingly capable AI systems.
What this adds
The new model’s release is part of Anthropic’s broader strategy to enter the cost-sensitive enterprise market, offering a faster and cheaper model designed for routine coding and business tasks.
Despite calls for a slowdown in AI innovation, Anthropic continues to release new models at a rapid pace, reflecting the company's focus on rapid commercial expansion.
The release of Claude Haiku 5.5 comes as Anthropic prepares for its IPO, which has been pushed back to mid-October, with a listing expected days before the U.S. midterm elections.
Background
Claude creator Anthropic has pushed back its initial public offering (IPO) marketing to mid-October, with a listing expected days before the U.S. midterm elections.
What's confirmed
- On average, it costs around 75% less to run than Claude Haiku 4.5.
- Anthropic today announced the new Claude Haiku 5.5 model, positioning it as the model of choice for high-volume, cost-sensitive tasks.
What's still developing
- There’s also Fable/Mythos, which is even more capable and costly, which represents Anthropic’s highest tier.
- Last month, Anthropic also announced the completion of a $13 billion Series F fundraising round led by ICONIQ, giving the company a post-money valuation of $183 billion.
- However, as is the case with all of these announcements, we'll have to see how Haiku 5.5 actually performs in real life before declaring it a powerhouse for its weight bracket.
- For a company that built its brand on frontier reasoning models, leading with a cost cut on the cheap tier says something about where the real AI spending battle is happening right now.
- A couple of weeks ago, OpenAI and Anthropic were talking about a possible moratorium on AI innovation and the need to cut down the pace of development.
- To explore all models available in GitHub Copilot, see our documentation on models and get started with Copilot.
- Under default model enablement, new models are automatically enabled unless an administrator has turned off the global default or explicitly disables this model.
- Anthropic is continuing to release new AI models at a rapid clip, despite its CEO’s pleas for a unilateral slowdown to give the industry’s safety frameworks time to catch up with the technology’s capabilities.
