DeepSeek

“Despite the promise of cutting-edge AI capabilities, performance was disappointing; only 2 of 9 requests succeeded, with a frustrating average latency of nearly 800ms, highlighting a significant inconsistency and costly API design. While the "FIM with special characters and symbols in code" feature performed impressively, the overall experience lacked reliability and efficiency, making it hard to justify the investment.”

“DeepSeek's API is unreliable garbage—barely half your requests work, pricing endpoints are broken at absurd rates, and when things do work, they're dog-slow (3+ seconds for code completion). Skip it until they fix their infrastructure; there's no point paying for a service that fails more often than it succeeds.”
