Pricing
Official Grok 4.7 post and docs.x.ai list $2/$6 starting rates (same as 4.6), cached input $0.50/M, and a 2×-price fast variant. Rates double above 200K prompt tokens ($4/$12; cached $1.00). Verify docs.x.ai for live tiers.
Availability
API model grok-4.7 (docs knowledge cutoff May 2026); also in Cursor, Grok Build, and GitHub Copilot (Pro through Enterprise; Business/Enterprise via model policy). Grok 4.6 remains available. Grok Build added cross-session memory on 2026-09-16 (/memory, /dream). Grok Voice Transcribe 2.0 (2026-09-18) is a separate speech-to-text API at $0.10/hr batch and $0.20/hr streaming—not Grok 4.7 audio. Grok Voice 3.0 (grok-voice-3.0, 2026-10-14) is a separate speech-to-speech model at $0.08/min ($4.80/hr), the same price as Grok Voice 2.0. grok-voice-latest now points at 3.0. grok-voice-2.0 is deprecated; the speech-to-speech API shape is unchanged. GitHub Copilot deprecated Grok 4.5 on 2026-10-19; the suggested Copilot alternative is Grok 4.7.
Use cases
- Long-running agentic coding and knowledge work
- Interactive / visual application first passes
- Tool-heavy software engineering agents
- Vision + text workflows via xAI API
Strengths
- Tuned for longer-running agents and self-verification vs Grok 4.6
- 500K context for large codebases and sessions
- Same headline $2/$6 API price as 4.6; Cursor and Copilot distribution
Limitations
- Closed weights
- Ecosystem smaller than OpenAI/Anthropic
- Long-prompt tier doubles token rates above 200K

- Claude FableAnthropicAnthropic’s Claude Fable 5.1 — the most capable widely released Claude for long-horizon agents, deep reasoning, and demanding coding workflows. Mythos 5.1 is the same underlying model with relaxed cyber/life-sciences safeguards for trusted-access programs.
- Claude OpusAnthropicAnthropic’s Claude Opus 5.5 (API id claude-opus-5-5, released 2026-09-22) for complex agentic coding, enterprise work, long-context analysis, and careful instruction following. Anthropic says it matches Fable 5.1 on most work at a lower price. Fable 5.1 remains a separate higher list-price SKU. Sonnet 5.5 (claude-sonnet-5-5, 2026-09-28) is the current Sonnet at the same $2/$10 list price as Sonnet 5. Haiku 5.5 (claude-haiku-5-5, 2026-10-07) is the current Haiku.
- Claude SonnetAnthropicAnthropic’s Claude Sonnet 5.5 (API id claude-sonnet-5-5, released 2026-09-28) for well-scoped everyday coding, agents, and documents. List price matches Sonnet 5 at $2/$10 per 1M tokens. Opus 5.5 remains the high-stakes tier; Haiku 5.5 (2026-10-07) is the low-cost subagent and high-volume tier.
- Gemini 3.1 ProGoogleGoogle’s Pro-class Gemini for hard reasoning and native multimodal work. Prefer API id gemini-3.1-pro-preview; Gemini 3.5 Pro remains partner-testing. This slug is not Gemini 4 Argon (gemini-4-argon, public 2026-10-13). On the Gemini API, gemini-2.5-pro has no announced shutdown date and is not deprecated; access is limited to projects that have already used it.
- Gemini 4 ArgonGoogleStable Gemini API id gemini-4-argon, released 13 October 2026. Google’s model page describes it as the flagship for complex software engineering, deep mathematical and scientific problems, autonomous multi-step agents, and long decode. Thinking can be set to low, medium, or high. The long-decode guide names medium as the default for most coding and agentic work. It documents function calling, structured outputs, code execution, search grounding, URL context, and file search. Computer use is in preview. The model page does not document native MCP support. Image generation, audio generation, and the Live API are not supported.
- GPT-5.6OpenAIOpenAI’s GPT-5.6 family (Sol flagship, Terra balanced, Luna cost-efficient) for complex reasoning, coding, multimodal understanding, and agentic tool use. The gpt-5.6 API alias routes to Sol. GPT-6.1 Sol (gpt-6.1-sol, 2026-09-29) is the current lower-cost Sol; GPT-6 Sol and Luna (2026-09-22) are earlier cost tiers. This entry remains GPT-5.6, which is still available.
