* feat(rust): count tiktoken cl100k_base admission tokens in Rust The Rust admission token counter only had the Anthropic tokenizer, so every other model (OpenAI gpt-4 family, Azure, Gemini, Bedrock non-Claude, Mistral) tokenized with tiktoken on the Python inference worker. Add an exact cl100k_base counter to litellm-token-counter: the vendored rank file (base64 token / rank lines, the bytes Python's tiktoken uses) is parsed into a byte-level BPE model and the cl100k split pattern is a handwritten scanner over the shared Unicode classes, so no regex engine runs per request. Both tokenizers share the message, tool and reply-priming accounting. The PyO3 TokenCounter gains a from_cl100k_ranks constructor; Python reads the rank file and passes it in, the way claude_json_str already works. The bridge selects the counter through the same predicates litellm.token_counter uses (huggingface_tokenizer_kind, openai_tokenizer_encoding), declines o200k_base, downloaded HuggingFace and custom tokenizers to Python, and budget reservation counts once per distinct tokenizer a request names. The legacy gpt-3.5-turbo-0301 message accounting (4 per message, -1 per name) stays in Python: the selector declines it through the predicate token_counter itself uses. * feat(rust): count tiktoken o200k_base admission tokens in Rust (#40794) Add a handwritten o200k_base split scanner and TokenCounter::from_o200k_ranks next to the cl100k_base counter, sharing MergeRanks and the request accounting. The Python bridge selects it when openai_tokenizer_encoding names o200k_base, so gpt-4o, gpt-4.1, gpt-5, o1/o3/o4 and chatgpt-4o requests stop tokenizing on the Python worker under LITELLM_RUST=true Co-authored-by: yassin <yassin@berri.ai> --------- Co-authored-by: yassin <yassin@berri.ai> Co-authored-by: devin-ai-integration[bot] <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
