can probably be removed here +corresponding start.ts, anthropic have deprecated in favor of ANTHROPIC_DEFAULT_HAIKU_MODEL which you have now also included,
I think can also close #89 then, since original question and followup comment are addressed by this PR

This pull request introduces major improvements to token counting and model compatibility for Anthropic and OpenAI-style chat and tool calls. The most significant changes include a complete rewrite of the token counting logic to support multiple model tokenizers, improved handling of tool tokens, and new endpoints for Anthropic-compatible token counting. Several translation functions now properly account for cached tokens, ensuring more accurate usage reporting.
Token counting and model compatibility improvements:
src/lib/tokenizer.tsto support multiple GPT encoding schemes, more accurate token counting for messages and tools, and dynamic model-based constants. The new implementation allows for flexible token calculation across Anthropic and OpenAI models, including tool call and parameter support.Anthropic endpoint and translation enhancements:
/v1/messages/count_tokensendpoint, with handlerhandleCountTokensinsrc/routes/messages/count-tokens-handler.ts, to accurately compute input tokens for Anthropic requests, including model-specific adjustments and tool bonuses. [1] [2] [3] [4]non-stream-translation.tsandstream-translation.tsto subtract cached tokens from input token counts and include detailed cache token usage in the response, improving Anthropic usage reporting. [1] [2] [3]Model and payload type improvements:
Modelinterface insrc/services/copilot/get-models.tsto support new capabilities and ensure compatibility with the updated tokenizer.ChatCompletionResponsetype insrc/services/copilot/create-chat-completions.tsto includeprompt_tokens_details, allowing reporting of cached token usage.Configuration and setup updates:
README.mdandsrc/start.tsto include new environment variables for model selection and non-essential traffic disabling, supporting the expanded Anthropic model options. [1] [2]
