Token-Space Font Compiler Generates Fonts with Fixed Token Widths
Key point
The open-source Token-Space Font Compiler generates custom fonts where each token occupies a fixed width, supporting presets for DeepSeek V4.1 Flash, ctok (Claude approximation), and various BPE tokenizers.
Details
The tool compiles a base font with tokenizer-specific shaping rules so that each token occupies 3 em. It supports presets including DeepSeek V4.1 Flash, ctok v3/v4.7/v4.8 (unofficial Claude approximations), and standard tokenizers like o200k_base, cl100k_base, p50k_base, and r50k_base. Experimental presets are available for Kimi K3, GLM-5.3, Llama 3, Trinity Large Thinking, Laguna M.1, Qwen 3.6, Gemma 4, and Gemini 3.5 Flash. The tool provides integration guides for Discord (via Vesktop) and Slack. It is explicitly not an exact billing counter; audits show 59 ID mismatches in 2,984 DeepSeek checks and 16 count/width mismatches in 2,984 ctok v4.8 checks.
