  SUTRA bills usage on a per-token basis through an OpenAI-compatible API.
  Production access is arranged with Two AI (Numeric) - the docs direct
  developers to contact Numeric for enterprise API access. A SUTRA for
  Startups program has been promoted offering up to 1 billion free tokens.
  SUTRA's efficient tokenizer reduces token consumption by roughly 3-5x for
  non-English languages, lowering effective per-language cost. Specific
  current per-model rates are not publicly reconciled in this artifact.
notes: >-
  Historically published SUTRA tiers referenced SUTRA-Pro / SUTRA-Online at
  about $1.00 per 1M tokens (input and output) and SUTRA-Light at about $0.75
  per 1M tokens. Current SUTRA-V2 / SUTRA-R0 rates were not confirmed on a
  public pricing page at capture time - reconciled is false. Verify all rates
  directly with Two AI before relying on them.
