## A Fine-Tuned GPT for De Novo Therapeutic Antibodies
|
| 11 |
+
|
| 12 |
+
### What are antibodies?
|
| 13 |
+
|
| 14 |
+
Antibodies are proteins that bind to a target protein (called an antigen) in order to mount an immune response
|
| 15 |
+
|
| 16 |
+
They are incredibly **safe** and **effective** therapeutics against infectious diseases, cancer, and autoimmune disorders.
|
| 17 |
+
|
| 18 |
+
### Why aren’t there more antibodies on the market?
|
| 19 |
+
|
| 20 |
+
Current antibody discovery methods require a lot of capital, expertise, and luck.
|
| 21 |
+
|
| 22 |
+
Generative AI opens up the possibility of moving from a paradigm of antibody discovery to antibody generation.
|
| 23 |
+
|
| 24 |
+
However, work is required to translate the advances of LLMs to the realm of drug discovery.
|
| 25 |
+
|
| 26 |
+
### What is AntibodyGPT?
|
| 27 |
+
|
| 28 |
+
A fine-tuned GPT language model that researchers can use to rapidly generate functional, diverse antibodies for any given target sequence
|
| 29 |
+
|
| 30 |
+
### Key Features
|
| 31 |
+
|
| 32 |
+
- Rapid generation
|
| 33 |
+
- Only requires target sequence
|
| 34 |
+
- Outputs diverse, human-like antibodies
|
| 35 |
+
|
| 36 |
