Anthropic vs Together AI: Token Pricing, Speed & Intelligence
Full comparison of Anthropic and Together AI — live token pricing, latency, throughput, context window, strengths, weaknesses, and best use cases. Rates sourced from public APIs — verify before use.
Anthropic
Claude 5 — Fable 5.1, Opus 5, Sonnet 5, Haiku 4.5 with 1M context
Anthropic builds the Claude model family, now in its fifth generation. The Claude 5 lineup includes Fable 5.1 and Opus 5 at the frontier (1M+ token context, reasoning models), Claude Sonnet 5 for production workloads, and Haiku 4.5 for cost-efficient inference. Anthropic also offers Claude Code (agentic coding) and Claude Science (research) as specialised products. Prompt caching is available at up to 90% discount.
Together AI
MiniMax M3, Kimi K3, GLM-5.3, DeepSeek V4 Pro, gpt-oss-120B — plus GB200/B200 GPU clusters
Together AI offers hosted inference for open-weight models, GPU clusters, provisioned throughput and fine-tuning. Compare listed rates and check the provider for current models, availability and terms.

Frequently asked questions
Anthropic FAQs
What are the latest Anthropic Claude models?
The Claude 5 family includes Fable 5.1 and Opus 5 (frontier reasoning), Claude Sonnet 5 (balanced), and Haiku 4.5 (efficient tier). Claude Code is a specialised agentic coding product. Check docs.anthropic.com/en/docs/about-claude/models for current pricing.
What is the context window for Claude 5 models?
Claude 5 Opus, Fable 5, and Mythos 5 all support 1M+ token context windows, enabling full-codebase and book-length document analysis in a single call.
How does Anthropic prompt caching work?
Anthropic's prompt caching lets you mark portions of your prompt (system prompts, documents, tool definitions) to be cached server-side. Cached tokens are billed at 10% of the standard input price after the first write, making repeated long-context calls dramatically cheaper.
Together AI FAQs
What new models did Together AI add in 2026?
Together AI expanded its catalog with MiniMax M3, Kimi K3, GLM-5.3, DeepSeek V4 Pro 0813, gpt-oss-120B, Muse Glimmer 30B, and the full Qwen3.x family. Check api.together.ai/models for current pricing.
How much does Together AI cost?
Together AI uses per-token pricing across its model catalog. Check api.together.ai/models for current rates on MiniMax M3, DeepSeek V4 Pro, GLM-5.3, Llama 3.3 70B, and other models.
Does Together AI offer GPU compute?
Yes. Together AI offers GPU clusters with H100, H200, B200, and GB200/GB300 NVL72 (contact sales). Check together.ai/pricing for current GPU compute rates.

Provider category context
Anthropic is a frontier lab, founded in 2021. Together AI is a inference api, founded in 2022. Anthropic as a frontier lab trains and serves its own proprietary models. Together AI as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers but without access to proprietary frontier models.
How to choose between them
Choose Anthropic if you need claude 5 family leads on coding and reasoning benchmarks. Choose Together AI if you need open-model catalog — minimax m3, kimi k3, glm-5.3, deepseek v4 pro, gpt-oss-120b, qwen3.x, llama 4. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
