O-Series Reasoning Models
Reasoning models use explicit step-by-step thinking for complex problem-solving. They require higher minimum completion tokens (2000-3000) and are best for analytical tasks.
| Model | Credits | Context | Min Tokens | Best For |
|---|---|---|---|---|
| O1 | 6 | 200K | 3000 | Deep reasoning, complex problems |
| O1 Mini | 3 | 128K | 2000 | Faster reasoning with strong analytics |
| O3 Mini | 3 | 128K | 2000 | Next-gen compact reasoning |
GPT-4 Series
| Model | Credits | Context | Description |
|---|---|---|---|
| GPT-4o | 5 | 128K | Specialized for specific tasks, excellent performance |
| GPT-4o Mini | 1 | 128K | Balanced for everyday tasks, efficient |
| GPT-4.1 Nano | 0.5 | 64K | Lightweight for speed and low-cost |
| GPT-4.1 Mini | 1 | 128K | Efficient with solid everyday performance |

Troubleshooting
Rate limit errors (429)
Rate limit errors (429)
Cause: Too many requests to OpenAI APISolutions:
- Implement request throttling
- Use exponential backoff retries
- Upgrade your OpenAI API tier
- Switch to GPT-4o Mini for high-volume use
Context length exceeded
Context length exceeded
Cause: Input + completion tokens exceed model’s context windowSolutions:
- Truncate conversation history
- Use models with larger context (GPT-5: 200K)
- Implement sliding window for message history
Slow responses with O1 models
Slow responses with O1 models
Expected behavior: Reasoning models take longerSolutions:
- Set user expectations (show “thinking…” indicator)
- Use O1 Mini instead of O1 for faster responses
- Reserve reasoning models for truly complex tasks
High costs
High costs
Solutions:
- Use GPT-5 Mini or GPT-4o Mini for most tasks
- Implement dynamic model selection
- Cache common responses
- Set max_tokens to limit completion length
