  Ran our DataAnalyticsBench benchmark on it: https://plotly.com/blog/claude-haiku-5-5-plotly-data-analyti...9x cheaper than Haiku 4.5 and 2 letter grades better. It's also now the fastest model (using the default speeds, not trying any of the other models "Fast" mode) to complete the exam.Similar ballpark to Luna in price, cost, and accuracy. These…

  Very important caveat if looking at the Artificial Analysis cost vs. intelligence graph (https://artificialanalysis.ai/?models=gpt-6-luna-low%2Cclaud...):"The site does not yet reflect tiered pricing, so provisional cost figures for Haiku 5.5 do not include the step up cost."Frankly, it's irresponsible for them to put the points on the chart if…

  Haiku 5.5 is an almost exponential jump over the last Haiku generation, with several benchmarks improving by 3-5x over Haiku 4.5 Haiku 5.5 goes from 15.7% -> 72.4% on OSWorld, 10.2% -> 45.9% on HLE without tools, 18.7% -> 57.4% with tools, and 6.4% -> 46.4% on Chartography. It even beats GPT-6 L...

  Anthropic just launched Claude Haiku 5.5, with average running costs around 75% below Haiku 4.5, according to the company. 5.5 Way better than GPT-6-Luna, close(r) to Sonnet 5.5 Anthropic says it also improves coding, computer use, and knowledge work. Haiku now has adjustable effort, letting de...

  Haiku 5.5 makes absolutely no sense lol. Anthropic somehow made Haiku MUCH smarter... then made it ~75% cheaper to run. and it's borderline better than Opus 5: Haiku 5.5 vs Opus 5: > GDPval: 1620 vs 1596 > AA-Briefcase: 1578 vs 1562 > HLE: 45.9% vs 53% > Terminal-Bench 4.0: 39.2% vs 46% yes....

  Claude Haiku 5.5 appears to be a massive jump in both agentic, coding & reasoning capability & incredible cost efficiency. In fact so much so that it is now competitive in cost with & even better than, similarly capable open-source models. It's crazy how Anthropic made that leap!

  My weekly limit __on a Pro sub__ has not gone over 50% since before the pre-Fable promos, but usage has been pretty much the same from my point of view. Maybe I am holding it right? Anyone else getting this?As such, I do not need to even reach for Haiku, and 4.5 was so inaccurate that it often cost more to do so in the past. Sonnet 5.5/low has…

  Haiku 4.5 came out two months after I joined Anthropic. It scored 15.7% on the test for operating a computer. Haiku 5.5 is out today, less than a year on. It scores 72.4% and costs around 75% less to run.

  It's around Qwen-3.8, and Sonnet 5.5 level, but a lot cheaper. It is also really fast.My tests for Haiku 5.5: https://aibenchy.com/compare/anthropic-claude-haiku-5-5-xhig...Twice as expensive as Luna, but also considerably smarter too:

  Claude Haiku 5.5 is out 🎉 It's a cheap, fast and very capable small model. ~75% cheaper to run than Haiku 4.5 with an adjustable effort setting. My team loves it as a subagent alongside Opus 5.5.

  My complaint about Haiku 4.5 was that it was 10x the price of GPT-6 Luna.> Claude Haiku 5.5 is priced 90% lower than Claude Haiku 4.5 for requests up to 100,000 tokens, and 50% lower for requests over 100,000 tokensHaiku and Luna now have the exact same price up to 100,000 tokens. Luna is now cheaper for anything after 100,000 tokens, even after…

  Introducing Claude Haiku 5.5: the cheapest, fastest, and most capable small model we've ever released. On average, it costs around 75% less to run than Claude Haiku 4.5.

  Anthropic just dropped Haiku 5.5. Their fastest Claude ever. 90% cheaper than Haiku 4.5 for most requests. AI agents just got way cheaper.

  About time Anthropic released a competitive cheap model. Haiku 4.5 has been too expensive compared to its performance for months now (in fact I don't remember being too impressed even when it was released). This one actually looks worth using in some scenarios. If it's really as much of a step up from Luna as the benchmarks they've shown indicate…

  Anthropic announced haiku 5.5, I go into Claude code, it's already there OpenAI announced gpt 6 in chat, I check and it's still 5.6

  > Claude Haiku 5.5 is our fastest model to date at each model’s standard speed, although it runs less quickly than our Opus models in Fast Mode.Opus 5.5 runs 117 tps average on Openrouter, so it must be at least 10-20 tps slower for them to mention. IDK why they mention this as it does not help for marketing though.

  Haiku 5.5 Max reaching Sonnet 5.5 High performance in these benchmarks - sometimes with lower costs. Fascinating.
