Frequently Asked Questions
ClaudeWhat is Claude?▼
Claude is a family of AI assistants built by Anthropic. It is available via API and consumer products.
ClaudeHow much does Claude API cost?▼
Claude Sonnet 4.5 costs $3/M input and $15/M output tokens. Opus pricing varies by tier.
ClaudeDoes Claude support images?▼
Yes. Claude supports image understanding (vision) across Sonnet and Opus models.
ClaudeWhich Claude model should I choose?▼
Sonnet 4.5 offers the best balance of speed and capability for most tasks. Opus 4.6 is ideal for complex reasoning and research. Haiku 4.5 is best for high-volume, low-latency workloads.
ClaudeWhat is Claude extended thinking?▼
Extended thinking is a feature in Opus-tier models that allows Claude to reason through complex problems step-by-step before responding, improving accuracy on math, logic, and coding tasks.
GPT-4oWhat is GPT-4o?▼
GPT-4o (omni) is OpenAI's flagship multimodal model supporting text, audio, image, and video.
GPT-4oHow does GPT-4o pricing compare?▼
GPT-4o costs $2.50/M input and $10/M output. GPT-4o-mini is significantly cheaper.
GPT-4oCan GPT-4o process audio?▼
Yes. GPT-4o natively processes audio input and generates audio output.
GPT-4oWhat is the difference between GPT-4o and GPT-4?▼
GPT-4o is a newer omni-model that natively handles text, audio, image, and video in a single architecture. It is faster and cheaper than original GPT-4 while matching or exceeding its quality.
GPT-4oDoes GPT-4o support function calling?▼
Yes. GPT-4o supports structured function calling (tool use) via the OpenAI API, allowing it to invoke external tools and APIs within conversations.
How to Choose
Choosing between Claude and GPT-4o depends on your primary workload. Consider these factors:
- Context-heavy tasks (document analysis, code review) — prioritize the larger context window.
- Cost-sensitive workloads (high-volume API calls) — compare per-token pricing and free-tier availability.
- Multimodal requirements (image/audio processing) — verify native support rather than relying on workarounds.
- Ecosystem lock-in — check SDK maturity, cloud provider partnerships, and migration paths.
We recommend testing both models on your actual use case with a small sample before committing to a provider. Most offer free tiers sufficient for evaluation.
