Terms of use.

Who these terms are with

This website is operated by Fahrenheit Research, a company based in the United States, of 440 N Barranca Avenue 9029, Covina, CA 91723 (“we”, “us”). By using the site you accept these terms. If you do not accept them, please do not use it.

What this website is

It describes our research and the small language models we build. It is information, not a product you can use here: there is nothing to sign up for, nothing to buy, and no model running on this site. Nothing on these pages is an offer, a quotation or a contractual commitment, and no agreement exists between us until it is set down separately and signed.

What our figures mean — please read this one

Every number on this site comes from our own internal testing, unless the page says otherwise and names its source. They are not independent benchmarks and have not been audited or verified by anyone outside the company. Each model page states what was measured, on which hardware, and over how many samples, and we publish the weak spots alongside the good results. Please read those notes: a figure without its method is not worth much.

Measured performance will not transfer unchanged to your own setting. Our timing and memory figures were obtained on specific machines — in most cases 16 GB Apple silicon MacBook Air M4 and M5 laptops — and different hardware, different quantisation, different load or different data will give different results. Where a model’s peak memory has not been measured yet, we say so rather than estimating it. Nothing here is a warranty of performance, accuracy or fitness for any purpose of yours.

The demonstrations are illustrations

The interactive panels on the model pages are illustrations. They replay pre-written example content to show the shape of a model’s work; they do not run the model, they perform no inference, and they send nothing anywhere. The voice panels in particular draw a waveform and play no audio, and are labelled as such on the page. Where a timing figure appears beside an illustration, it comes from our separate test runs and not from what you are watching.

Models we build on

Our models are derived from third-party open models, and each model page names the licence involved. Those upstream models remain the work of their publishers and are governed by their own licence terms, which travel with the weights. Nothing on this site grants you any right in an upstream model, and nothing here is a representation about one on its publisher’s behalf.

Our material

The text, design, photographs, prints, diagrams and code of this website belong to us or to our licensors, and the names Fahrenheit Research, Balsa, Gati and Methodal are ours. You may read the site, and quote or link to it for comment, review, reporting or research, with attribution. You may not copy the site or substantial parts of it, present our material as your own, or use it to train a model or build a competing service without our written permission.

Using the site decently

Please do not try to break the site, interfere with its availability, probe it for vulnerabilities without telling us, scrape it in a way that degrades it for others, or use it against any applicable law. If you find a security problem, we would much rather hear from you at research@f-r.co than read about it later.

Availability

We make no promise that the site will always be available, or free of errors. We may change, suspend or withdraw any part of it, including any model described on it, at any time. Model names, sizes and figures may change as the work does.

Links out

Where we link to someone else’s site — a model card, a licence, a paper — we do so because it is useful. We do not control those sites and are not responsible for their content or their privacy practices.

Liability

The site is provided as it is. To the fullest extent the law allows, we exclude the implied warranties and give none as to accuracy, completeness or fitness for a particular purpose, and we are not liable for any indirect or consequential loss, or for lost profit, revenue, data or goodwill, arising from your use of the site or your reliance on anything published on it. Decisions you take on the strength of our published figures are yours; evaluate any model on your own data and hardware before depending on it.

Nothing in these terms limits liability that cannot lawfully be limited, including for death or personal injury caused by negligence, or for fraud.

Changes

We may revise these terms. The version on this page is the one in force, and the date below changes when it does.

Law

These terms, and any dispute arising from them or from your use of the site, are governed by the laws of the State of California, United States, whose courts have exclusive jurisdiction.
