New Claude tokenizer inflates code API costs

A detailed analysis of LLM pricing reveals that comparing the dollar-per-million-tokens rate between models is deeply misleading without factoring in tokenizer efficiency. The piece demonstrates that Anthropic's new tokenizer inflates token counts by roughly 30% for code, acting as a stealth price hike on identically priced API tiers, and shows that a TypeScript file costs 73% more tokens on Claude than GPT.

// ANALYSIS

The AI pricing conversation has focused entirely on per-token rates while ignoring token volume, creating an illusion of parity.

–Anthropic executed a hidden ~30% price hike by deploying a less efficient tokenizer on its newer models while retaining its standard rate card.
–Tokenizer bloat disproportionately punishes code (especially TypeScript and Rust) over English prose.
–Builders of AI coding agents must measure the tokens-per-content ratio alongside the advertised rate to calculate true API costs.
