Together AI API error: {str(e)}

Error message

Together AI API error: {str(e)}

What it means

together_fn wraps any failure from the Together AI chat completions call in a generic Exception prefixed 'Together AI API error:'. The library re-raises with `from e` so the underlying cause (auth, network, model name, rate limit) is preserved in __cause__. It is a catch-all wrapper, so the real problem must be read from the chained message.

Solutions

  1. Read the chained exception (__cause__) message to identify the underlying Together API failure
  2. Verify the Together API key in config.ini is set and valid (test with curl against api.together.xyz)
  3. Confirm self.model matches an exact Together model slug (e.g. 'mistralai/Mixtral-8x7B-Instruct-v0.1')
  4. Retry with backoff if the message indicates 429/5xx; check status.together.ai for outages
  5. Check network/proxy access to api.together.xyz from the host

Example fix

// before
thought = provider.together_fn(history)
// after
try:
    thought = provider.together_fn(history)
except Exception as e:
    logging.error(f"Together call failed: {e}; cause: {e.__cause__}")
    raise
Defensive patterns

Strategy: try-catch

Validate before calling

import os
def validate_together(provider):
    assert provider.api_key and provider.api_key.startswith(("together-", "sk-")), "Set a valid Together API key in config.ini"
    assert provider.model and "/" in provider.model, f"Model '{provider.model}' is not a Together slug (expected 'org/model')"

Type guard

def is_together_slug(model: str) -> bool:
    return bool(model) and "/" in model and not model.startswith("gpt-")

Try / catch

try:
    thought = provider.together_fn(history)
except Exception as e:
    cause = e.__cause__
    if cause and "401" in str(cause):
        fix_api_key()
    elif cause and "429" in str(cause):
        schedule_retry_with_backoff()
    else:
        raise

Prevention

When it happens

Trigger: Any exception raised inside together_fn after the try block begins: Together HTTP client errors (invalid/missing API key, unknown model name, rate limiting, 5xx), network failures, or an empty response (choices missing).

Common situations: Expired or wrong TOGETHER_API_KEY in config.ini; model string like 'mistralai/Mixtral-8x7B' misspelled; free-tier rate limit hit; Together service outage; corporate proxy blocking api.together.xyz.
