Text and chat models for production AI workloads

Large language models are the workhorse of modern AI: chatbots, agents, summarisers, classifiers, translators. The category is the most crowded on Railwail — OpenAI, Anthropic, Google, Mistral, Meta, DeepSeek, xAI, and dozens of open-weights labs all compete here.

Ceny, kompromisy a úskalí

Pricing in text generation is almost always per-token, split into a cheaper input rate and a more expensive output rate. A million input tokens is roughly 750,000 English words, so even verbose prompts rarely push the per-call price above a few cents. Output is where bills grow: agentic loops that re-prompt themselves, long reports, and uncached few-shot examples add up quickly. Cache the system prompt, trim history aggressively, and prefer JSON-mode for structured tasks to keep token counts down.

The trade-off triangle is quality, latency, and cost. Flagship models (GPT-5, Claude 4.6, Gemini 2.5) cost ten to fifty times more than budget tiers (Haiku, Flash, Mini) and respond two to four times slower, but they reason deeper, follow instructions more reliably, and hallucinate less. For high-volume classification or extraction, a budget model is almost always the right call. For long-form analysis, code review, or anything user-facing, the flagship usually pays for itself.

Watch out for context dilution: when you stuff 200K tokens into the window, the model's attention spreads thin and it starts to ignore the middle of the prompt — even on long-context flagships. Retrieve the relevant 8-16K tokens with embeddings instead of pasting the whole document.

Porovnání modelů

Často kladené otázky

Which LLM is the cheapest on Railwail?

Budget models such as GPT-4o mini, GPT-5.4 Nano, DeepSeek V4 Flash and Gemini 3 Flash sit at the low end — from about $0.18 to $0.60 per million input tokens on Railwail today. The ranking changes with every provider price update, so sort the model grid above by price to see the current cheapest option.

Which model has the longest context window?

In the catalog, Gemini 3.1 Pro lists the largest context window (2M tokens), followed by GPT-5.4, Claude Opus 4.8 and DeepSeek V4 Pro with about 1M tokens each. For most workloads, 128K is more than enough; reach for the long-context tier only when you genuinely need to read a whole codebase or research paper in one prompt.

Open-source vs proprietary — which should I pick?

Open-weights models (Llama 3, Qwen, DeepSeek, Mistral, Mixtral) are catching up fast and win on price-per-token and data sovereignty. Proprietary flagships still lead on reasoning, multilingual coverage, and tool-use reliability. If you're cost-sensitive or need self-hosting, start open. If you're shipping to end-users, start proprietary and optimize down.

GPT-5 vs Claude 4.6 — which is better?

GPT-5 leads on raw benchmark scores, math, and code generation; Claude 4.6 leads on long-form writing, instruction-following nuance, and refusal-rate calibration. Both are within 5% of each other on most tasks. Run them side-by-side on your real prompts at /compare/gpt-5-vs-claude-4-6 — the differences are workload-specific.

How do I switch models in my code?

Railwail is OpenAI-compatible: you only change the `model` parameter. Same endpoint, same SDK, same request body. Try a new model in production by routing 10% of your traffic to it for a week and comparing quality, latency and cost.

Is JSON mode supported?

Not through the Railwail API yet: the chat endpoint currently does not forward `response_format` or tool definitions to the provider. Ask for JSON in the prompt and validate the answer with a Zod or Pydantic schema; many models follow a clear JSON instruction reliably.

Does Railwail support streaming?

Not yet. The Railwail chat endpoint returns the complete answer in one response; the `stream: true` parameter is currently ignored. For long answers, set a sensible `max_tokens` and show a loading state in your UI.

Is the API GDPR-compliant?

Railwail runs its platform on servers in Germany and does not train on your prompts. The request itself is processed by the provider of the chosen model, which may be located outside the EU; every model page names that provider, so you can pick one that matches your compliance requirements. Details are on the trust page.
