Our verdict

Writer suits teams that need a long context window and will pay for it. Its 1,000,000 token window sits at the 1,000,000 for this category, and output fees of $6 to $10 sit well past the €0.23 seen here.

Pros and cons

Pros

  • A 1,000,000 token context window matches the 1,000,000 for this category, so whole documents fit in one call.
  • One API spans several vendors, since palmyra x6, palmyra x5 and palmyra x4 pairs in-house Palmyra models with Claude, Gemini, DeepSeek, Kimi and GLM.
  • The same catalogue covers text, stills and motion, because palmyra x6, palmyra x5 and palmyra x4 puts image and video models beside the chat models.

Cons

  • Support runs on email and help centre only.
  • Input price from ranks 64 of 71 brands compared, so the cheap end of this market sits elsewhere.
  • Founded in 2020 and based in the US, Writer is a younger vendor than several gateway names here.

Who it suits

  • Teams feeding whole documents or repositories to a model, given a 1,000,000 token window.
  • Enterprises that need named certifications, SOC 2 Type II, ISO 27001 and ISO 27701 in place before a security review.
  • Developers who want several vendors behind one endpoint, since palmyra x6, palmyra x5 and palmyra x4 mixes Palmyra, Claude, Gemini, DeepSeek, Kimi and GLM.

Who should look elsewhere

  • Salad, where input fees of $0.06 sit well under Writer's $0.60 to $2.50.
  • Azure AI Foundry, whose catalogue of gpt 6 astra, gpt 6 luna and gpt 6 sol is centred on a single vendor's models.
  • Supascale AI, whose roster of DeepSeek V4 Pro, GPT 5.6 Sol and GPT 5.6 Terra reaches further into open weight families.

Pricing

Writer bills per token rather than by plan, and both directions sit high. Writer's input fees of $0.60 to $2.50 and output fees of $6 to $10 mean a long document run costs more here than on a gateway that resells the same underlying models. Output is the dearer side, so a chatty assistant bills faster than a long single prompt.

How Writer compares

Frequently asked questions

What does a Writer prompt cost?+

Writer is billed per token, with input fees of $0.60 to $2.50 and output fees of $6 to $10. Output sits above input, so responses cost more than the documents you send, and a chatty assistant bills faster than a long single prompt.

How much context can I pass to a Writer model?+

The largest context window listed for Writer is 1,000,000 tokens, which matches the 1,000,000 for this category. Long documents, contracts or code repositories can go into a single call instead of being chunked, which is the main reason teams pay a premium here.

Which models can I call through Writer?+

The catalogue runs to palmyra x6, palmyra x5 and palmyra x4, mixing in-house Palmyra models with Claude, Gemini, DeepSeek, Kimi and GLM families plus image and video picks. One endpoint covers several vendors, so a task can move to a cheaper model without code changes.

What compliance certifications does Writer hold?+

Writer lists SOC 2 Type II, ISO 27001 and ISO 27701 among its certifications and frameworks, which is the clearest reason regulated buyers shortlist it. The legal entity behind the API is Writer, Inc., so contracts, data agreements and audit requests are handled by the same company you sign up with.

How do I get help from Writer support?+

Support runs through email and help centre. That is enough for API questions and billing queries, but teams that need live chat during an outage should settle the escalation path before launch, since the listed channels are self service.

How does Writer's pricing compare with other providers here?+

Input fees of $0.60 to $2.50 and output fees of $6 to $10 put Writer in the expensive part of this market, well past the €0.08 entry price. On input price from it ranks 64 of 71 brands compared.

Would Salad cost less for the same prompts?+

Salad lists input fees of $0.06 against Writer's $0.60 to $2.50, so token spend can be a fraction of the Writer figure. Salad is the cheaper route for plain inference, while Writer adds a 1,000,000 token window and a named compliance list alongside.
