For developers: Claude Pro is competitively priced and includes Claude Code — a strong coding assistant comparable to Cursor or Codex. Free tier is generous for occasional use.

Gemini (Google) — API pricing

Free tier

• Gemini 2.5 Flash-Lite and other models
• Generous rate limits
• Google AI Studio access
• Content used to improve products

Paid tier (pay-per-use)

Model	Input ($/1M tokens)	Output ($/1M tokens)
Gemini 3.1 Pro Preview	$2.00 - $4.00	$12.00 - $18.00
Gemini 3 Flash Preview	$0.50	$3.00
Gemini 2.5 Pro	$1.25 - $2.50	$10.00 - $15.00
Gemini 2.5 Flash	$0.30	$2.50
Gemini 2.5 Flash-Lite	$0.10	$0.40

For developers: Gemini API is the most cost-effective for API usage. Flash-Lite at $0.10/$0.40 per 1M tokens is unbeatable for high-volume applications. Free tier perfect for prototyping.

Model capabilities

Reasoning and problem-solving

Winner: ChatGPT GPT-5.4 Thinking

GPT-5.4 Thinking excels at complex multi-step reasoning, mathematical proofs, and logic puzzles. It shows its work with explicit “thinking” tokens (visible in Pro plan).

Runner-up: Claude Opus

Claude Opus handles nuanced reasoning well, especially for open-ended analysis and creative problem-solving. Strong at understanding context and implicit requirements.

Gemini 3.1 Pro is competitive but less consistent on edge-case logic puzzles. Strong at practical reasoning for real-world tasks.

Coding and software development

Winner: Claude with Claude Code

Claude Pro includes Claude Code — an AI coding assistant that executes code, creates files, and iterates on implementations. Excellent at:

• Refactoring and code review
• Debugging complex issues
• Writing tests and documentation
• Multi-file codebases

Runner-up: ChatGPT with Codex

Codex (Plus/Pro) is OpenAI’s coding agent. It can:

• Read and modify files
• Execute code in sandboxed environments
• Install packages and dependencies
• Integrate with VS Code (via extensions)

Gemini is solid for code generation but lacks the integrated execution environment. Better for code snippets than full development workflows.

Long-form writing and editing

Winner: Claude

Claude (especially Opus and Sonnet) excels at:

• Long-form content (articles, reports, essays)
• Maintaining consistent tone and voice
• Understanding complex instructions
• Detailed editing and critique

Runner-up: ChatGPT

GPT-5.3 and GPT-5.4 are strong writers but sometimes verbose. Canvas feature (interactive editing) makes revisions easier.

Gemini is competent but less nuanced for creative writing. Better for technical or factual content.

Multimodal (images, audio, video)

Winner: Gemini

Gemini 3.1 Flash Image and native multimodal embedding makes it unmatched for:

• Image analysis and understanding
• Video content processing (up to 2M tokens context)
• Audio transcription and analysis
• Combined text/image/video inputs

Runner-up: ChatGPT

GPT-5.4 supports vision (images) and generates images with DALL-E 3. Voice mode with video (Plus/Pro) enables multimodal conversations.

Claude analyzes images but doesn’t generate them. Vision capabilities are solid but less robust than Gemini.

Document analysis and research

Winner (tie): Claude and ChatGPT

Claude handles massive documents (200K context) with precise extraction and analysis. Projects feature organizes multiple docs. Research mode synthesizes findings.

ChatGPT Deep Research (Plus/Pro) conducts multi-step research with web searches, synthesis, and citations. Tasks feature automates research workflows.

Gemini has Google Search grounding (5,000 free queries/month, then $14/1K) for real-time information retrieval. Strong at fact-checking and current events.

Speed and latency

Winner: Gemini Flash models

Gemini 2.5 Flash and Flash-Lite are optimized for sub-second responses. Flash Live (Live API) enables real-time audio-to-audio interaction with minimal latency.

Runner-up: ChatGPT Instant

GPT-5.3 Instant is fast for everyday queries. Pro plan gets “fastest” tier with priority compute.

Claude Sonnet is reasonably fast. Opus can be slower due to its reasoning depth. Haiku (lightweight model) is faster but less capable.

Context window comparison

Context window determines how much text (code, documents, conversation) a model can process at once.

Model	Context window	Equivalent
ChatGPT GPT-5.3 Instant	27K - 54K tokens	~12-40 pages
ChatGPT GPT-5.4 Thinking	256K - 400K tokens	~320-680 pages
Claude Opus/Sonnet	200K tokens	~150,000 words
Gemini 3.1 Pro Preview	2M tokens	~1,500,000 words
Gemini 2.5 Flash	1M tokens	~750,000 words

Winner: Gemini

Gemini’s 1-2M token context is unmatched for processing entire codebases, books, or large datasets in one request. Use context caching to reduce costs for repeated prompts.

ChatGPT Pro’s 400K context (GPT-5.4) and Claude’s 200K are sufficient for most use cases. Free tiers have smaller windows (27K-54K for ChatGPT Free/Go).
