Shader Model 1 was the first shader model created in DirectX. It introduced vertex and pixel shaders to the first implementation of the programmable pipeline.

- HLSL functions
- Vertex shader assembly instructions (see Instructions - vs_1_1). Support for pixel shader instructions (ps_1_x) has been deprecated. To compile ps_1_x shaders as ps_2_0 shaders see Compiling Shader Model 1.
