What is the max output length for gpt-3.5-turbo-0125?

gpt-3.5-turbo-0125 supports up to 4096 output tokens per request. Plan your prompts to stay within this limit, and use the max_tokens or max_completion_tokens parameter to control output length.

Can you call gpt-3.5-turbo-0125 with the OpenAI SDK you already use?

Yes. gpt-3.5-turbo-0125 is served through an OpenAI-compatible endpoint. You can continue using your existing SDK.

What should you evaluate before moving production traffic to gpt-3.5-turbo-0125?

Test your tasks and compare with GPT-4o Mini, which offers significantly better intelligence at a comparable cost.

How much does prompt caching save on gpt-3.5-turbo-0125?

gpt-3.5-turbo-0125 supports prompt caching, which can significantly reduce costs for repeated prompts with shared prefixes. The cache read price is substantially lower than the standard input price. Check the current pricing page for the exact cache hit discount ratio for gpt-3.5-turbo-0125.

Does gpt-3.5-turbo-0125 support tool calling and structured output?

Yes. It supports JSON mode, reproducible outputs, and parallel function calling. Test with your specific tool definitions.

How does gpt-3.5-turbo-0125 compare with other models, and what should you compare?

Compare gpt-3.5-turbo-0125 against models of similar capability and pricing on your actual workload. Evaluate latency, output quality, instruction following, and cost per task. Run side-by-side tests with your own prompts — the best model depends on your specific use case, not just benchmark scores.

What is the rate limit for gpt-3.5-turbo-0125?

gpt-3.5-turbo-0125 rate limits vary by your MixRoute subscription plan. Check your plan details in the console for requests per minute (RPM) and tokens per minute (TPM) limits. Run a small load test before production to confirm your effective quota.
