The skill loads docs, typed schemas, pricing notes, and setup steps into your coding workspace so your agent has the right context. 2. **Configure** — Set the model field to the full model ID shown on this page and configure your RunAPI API key as an environment variable. The same key works across all models and providers. 3. **Call** — Use the skill instructions while adding prompt, input, and callback handling to your application. RunAPI routes the request to the provider, manages the async lifecycle, and returns structured JSON. 4. **Receive** — Read the task response by polling the task ID, streaming when supported, or handling the webhook callback at your configured URL. Generated outputs are stored and retrievable by task ID. ### What's different about gpt-4o-mini - **VS CODEX-AUTO-REVIEW: Fast, affordable GPT-4o model for everyday text tasks** — codex-auto-review - **VS GPT-5.2: Fast, affordable GPT-4o model for everyday text tasks** — Professional knowledge work; Thinking mode for deep tasks - **VS GPT-5.2-PRO: Fast, affordable GPT-4o model for everyday text tasks** — gpt-5.2-pro ## USE CASES **Customer support** Answer customer questions from a private knowledge base, reducing ticket volume. **Document analysis** Draft contract summaries and flag key clauses for attorney review. **Code generation** Auto-generate unit tests, code reviews, and refactoring suggestions in CI. ## Frequently asked questions about GPT 4o mini ### How do I select gpt-4o-mini? Pass the model ID shown in the quickstart. ### What's the rate limit on this variant? Per-key rate limits scale with your usage tier. The pricing page shows current limits. If you need higher throughput, contact support to discuss tier upgrades. ### Can I switch variants later? Yes. Variant is a parameter in the request. Switch by changing the model ID — no code changes, no re-authentication, no separate billing setup. All variants share the same API key and request shape. ### Does it stream? Where streaming is available, RunAPI streams end-to-end. LLM models support token-level streaming. Media models use async task polling or webhook callbacks for result delivery. ### Where do I report quality issues? Open an issue on the public GitHub repo or email support at contact@runapi.ai. Include the task ID and model ID so the team can investigate the specific generation. ### Do I need a separate provider account? No. Your RunAPI API key is enough to access this variant and every other model in the catalog. You do not need accounts with the underlying provider. ### RELATED - [gpt-5.4-nano](https://runapi.ai/models/gpt/5.4-nano.md) — by OpenAI · Input $0.20 / 1M tokens | Output $1.25 / 1M tokens - [gpt-5.6-luna](https://runapi.ai/models/gpt/5.6-luna.md) — by OpenAI · Input $0.20-$0.40 / 1M tokens | Output $1.20-$1.80 / 1M tokens - [gpt-5.4-mini](https://runapi.ai/models/gpt/5.4-mini.md) — by OpenAI · Input $0.75 / 1M tokens | Output $4.50 / 1M tokens - [gpt-5.2](https://runapi.ai/models/gpt/5.2.md) — by OpenAI · Input $0.88 / 1M tokens | Output $7.00 / 1M tokens · Input $1.75 / 1M tokens | Output $14.00 / 1M tokens ### Start building with GPT. - [Create free account](https://runapi.ai/login) - [Read the quickstart →](https://runapi.ai/docs/api/openai/chat-completions) ## Building with a team?
