When to pick which
Heuristics derived from the spec table above. Always validate on your own prompts before committing — these are starting points, not verdicts.
Pick o4-mini for
- •output-heavy workloads (long-form generation, code, summaries) — o4-mini is meaningfully cheaper per output token
- •input-heavy workloads (long context, RAG, document QA) — o4-mini is cheaper per input token
- •latency-sensitive UX (chat, autocompletion) — o4-mini streams faster (~80 vs ~30 tok/s)
Pick Claude Opus 4.7 for
- •tasks needing a larger context window — claude-opus-4.7 fits 5x more tokens than o4-mini
Switching between them
For most use cases, switching providers means updating the model id and the request shape if the providers differ. Within the same provider, it's usually a single-line change.
From o4-mini to Claude Opus 4.7
# Before
model = "o4-mini"
# After
model = "claude-opus-4.7"If the providers differ (OpenAI vs Anthropic), you'll also need to swap the SDK / endpoint URL. Cross-provider migrations usually take 30 minutes to a few hours depending on how many features (streaming, function calling, tool use) you depend on.
Calculate cost on your own prompt
The examples above use generic input/output ratios. For an exact comparison, paste your real prompt into the calculator — it counts tokens with the right tokenizer for each model and shows side-by-side cost.
