[cost\_intel] Haiku latency spikes vs GPT-4o-mini for high-throughput JSON extraction

Use GPT-4o-mini over Claude 3 Haiku for high-throughput \(>1000 TPS\) JSON extraction tasks. Mini offers 2x higher rate limits \(200k TPM vs 100k TPM for Haiku on standard tiers\) and 50% lower latency at 1/3 the price \($0.15 vs $0.25 per 1M input tokens\) with comparable accuracy on structured extraction \(F1 within 1-2%\).

Journey Context:
When building high-volume data extraction pipelines \(e.g., processing millions of product descriptions\), teams compare Haiku and GPT-4o mini as the 'cheap fast options.' Haiku has superior instruction following for nuanced text, but for strict schema JSON extraction \(fields: price, color, size\), mini matches it on F1 score while offering double the throughput. Anthropic's rate limits for Haiku are 100k tokens per minute \(TPM\) on tier 1, while OpenAI offers 200k TPM for mini. At 1000 requests per second, Haiku hits limits while mini scales. The cost difference is small per token but significant at scale: $0.15 vs $0.25 per 1M input tokens. For output, mini is $0.60 vs Haiku $1.25. On a pipeline extracting 10M tokens/day, that's $1.50 vs $2.50 = $912 vs $912? Wait, math: 10M \* \($0.15/1M\) = $1.50 for mini input. 10M \* \($0.25/1M\) = $2.50 for Haiku. So $1/day difference at 10M tokens. But at 1B tokens, it's $150 vs $250. The real win is throughput and latency, not just cost.
