> The hot take is wrong. After ~50,000 production calls across both providers, here's what we actually see — and why our default is still OpenAI for SA chat workloads.

We are not religious about model providers. We use Claude, we use Gemini, we use Llama via Bedrock. But when a South African client asks us "which model should we put behind our customer chatbot", our default is still OpenAI's GPT-4o and gpt-4o-mini.

Here's why, after about 50,000 production calls split across providers.

## Latency from SA matters

Claude is hosted primarily in US-East. Round-trip from JHB averages 380ms on the first token, 220ms steady. OpenAI's primary region is also US but via Azure's South African POP it's 180ms first token. For a chat widget where the user is watching for the response, that 200ms difference is felt.

## SA English vs International English

GPT-4o handles Afrikaans-flavoured English, isiZulu transliteration and our number conventions ("R10k" for ten thousand rand) noticeably better than Claude in our blind A/B testing. Not by a huge margin — but consistently.

## JSON-mode reliability

For production agents that must return structured JSON, gpt-4o's `response_format: json_object` is rock-solid. Claude's structured output via XML tags is good but not as predictable in our hands.

## Cost

GPT-4o-mini is roughly half the cost of Haiku and a tenth the cost of Sonnet for short-turn conversational workloads. For a SA SME running 10k chats a month, that's a real budget line.

None of this is forever. We re-evaluate every quarter. If you want our current per-use-case recommendation, drop us a line.
