Anthropic releases Claude Haiku 5.5 small model and halves Sonnet 5.5 cache read prices

Anthropic PBC today released Claude Haiku 5.5, pricing its newest small model at roughly a quarter of what Haiku 4.5 costs to run.

Claude Sonnet 5.5 is getting cheaper as well, since the company is halving what it charges for cache reads on that model.

Two weeks after Opus 5.5 launched Sept. 22, Haiku 5.5 makes three models in the 5.5 generation. Anthropic is aiming it at repetitive work. High-volume summaries and classification are the main target, and coding teams can also use the model as a subagent that Opus 5.5 or Sonnet 5.5 hands smaller tasks to. Because no Anthropic model runs faster at standard speed, the company suggests it for live customer support and browser automation.

Anthropic’s running-cost figure rests on a steep cut to list prices. Haiku 4.5, released last October, costs $1 per million input tokens and $5 per million output. For prompts of up to 100,000 tokens, which Anthropic said covered about 90% of the older model’s requests, Haiku 5.5 is 90% cheaper on input and output alike, at 10 cents and 50 cents per million tokens. Longer prompts get a 50% discount. The 75% average saving the company quotes takes in a new tokenizer that uses slightly more tokens per task. Cost can be tuned further, since Haiku 5.5 is the first Haiku model with an adjustable effort setting.

The 10-cent and 50-cent rates match what OpenAI Group PBC charges for GPT-6 Luna, the low-cost model it launched last month. Anthropic’s published benchmarks have Haiku 5.5 ahead of Luna on all six tests where both have a score. On OSWorld 2.1, a test of agents operating a real computer through long multistep tasks, the new model scored 72.4% on the offline subset against 48.9% for Luna. Luna scored 16.4% on the Terminal-Bench 4.0 agentic coding test, less than half the new model’s 39.2%. For complex agentic coding, Anthropic still points customers to Sonnet 5.5 and Opus 5.5.

Asana Inc. was among the customers that tested Haiku 5.5 before release, running it through the evaluation suite for its AI Teammates agent. Task completion latency came in more than 30% lower than with the model Asana uses today, and inference on each agent turn ran up to 2.5 times faster. “It’s a noticeably snappier experience,” said Aaron Vinh, a staff software engineer at the company.

On safety, Anthropic said alignment testing turned up far fewer instances of misaligned behavior than Haiku 4.5 showed. Cybersecurity safeguards on the model allow more defensive work than Sonnet 5.5 permits. Penetration testing is still blocked, as are other techniques attackers are more likely to use, and organizations that need wider access can apply to the Cyber Verification Program Anthropic expanded on Tuesday.

The Haiku launch also came with a price cut for Anthropic’s midsize model. Cache reads on Sonnet 5.5, which launched Sept. 28, drop from 20 cents per million tokens to 10 cents. Because cached tokens account for a large share of what models consume, Anthropic expects the cut to take about 20% off the cost of most agentic work on the model.

Claude Max and Team subscribers will also start receiving monthly application programming interface credits for the Claude Platform this week. A Max 5x subscription comes with $100 a month, double that on Max 20x. Team accounts get up to $500 shared across their users, and the credits can go toward any Claude model.

Haiku 5.5 is available now on the Claude Platform as claude-haiku-5-5 and through Amazon Web Services Inc., Google Cloud and Microsoft Azure.

USA Today becomes the latest publisher to sue OpenAI

The publisher is seeking damages of more than $250 million.

USA Today Co., along with the several local newspapers it owns, is suing OpenAI over claims that the company copied “hundreds of thousands” of articles to train its AI models, as reported earlier by Reuters. In a filing on Thursday, the publisher asks for damages of more than $250 million, alleging OpenAI’s unauthorized use of its content “has done real and continuing” harm to its outlets.

This is just the latest in a string of copyright lawsuits filed against OpenAI. In addition to a copyright lawsuit filed by The New York Times, OpenAI is also facing legal action from The Intercept, CNET owner Ziff Davis, CBC/Radio-Canada, Encyclopaedia Britannica, Merriam-Webster, The Seattle Times, and a coalition of nearly 400 local newspapers.

“OpenAI’s commercial success rests on large-scale copyright infringement,” USA Today Co.’s lawsuit claims. It alleges that OpenAI never asked for permission to use its content, instead “took” USA Today ’s content to “build products worth hundreds of billions of dollars.” The Tennessean, Indy Star, The Columbus Dispatch, The Oklahoman, and several other local outlets are also included in the lawsuit.

OpenAI didn’t immediately respond to The Verge ’s request for comment.
