Uninformative LLM errors

[lockmeister]

Recommendation: make more informative errors based on LLM Exceptions

• when the context length is too long, inform the user, otherwise the error can be confused with being out of funds or hitting a daily limit
• cache warming seems to continue for a model even after the user switches to a new model, which is also confusing.

After switching to /model openrouter/anthropic/claude-3.5-sonnet , I get the error:
litellm.APIError: APIError: OpenrouterException

I checked openrouter funds, network access etc, there are no problems. I believe the problem was caused by my context length being too long, however the error message is not helpful in figuring this out.

I also see the following error, how
litellm.RateLimitError: AnthropicException - {"type":"error","error":{"type":"rate_limit_error","message":"Number of request
tokens has exceeded your daily rate limit (https://docs.anthropic.com/en/api/rate-limits); see the response headers for
current usage. Please reduce the prompt length or the maximum tokens requested, or try again later. You may also contact
sales at https://www.anthropic.com/contact-sales to discuss your options for a rate limit increase."}}

This cache warming error seen after switching to gpt-4o from sonnet:

Cache warming error: litellm.RateLimitError: AnthropicException -
{"type":"error","error":{"type":"rate_limit_error","message":"Number of request tokens has exceeded your daily rate limit
