TopxAI vs OpenRouter: what is the same and what differs
Compare TopxAI and OpenRouter model prices, routes and API formats, with dated sources and the scope of the private-deployment prices.
Both services put many providers' models behind one endpoint and one balance. The differences are in how many models, what a token costs, and what else is on offer. This page states what each side publishes; OpenRouter's numbers are from their documentation on 2026-09-24, with GPT-6.1 Sol rechecked on 2026-09-30 and Sonnet 5.5 on 2026-10-02, and may change.
November 12, 2026 update: Jev costs $0.055 per million input tokens, output free (it was $0.04494, 107% of TypeSafe's list price, before), and a costlier standby line answers, at $0.058, only when the main line fails.
November 10, 2026 update: since November 8 the GLM, Kimi and DeepSeek lines are all served from private deployments, at fixed prices. As of November 10, per million tokens (input / cache read / output): GLM-5.3-Abliterated $3.00 / $0.45 / $6.00, GLM-5.3-Flash-Abliterated $0.36 / $0.075 / $1.50, Kimi K3.1 Pro $0.50 / $0.30 / $5.00, deepseek-flash-Abliterated $0.42 / $0.105 / $1.50 and deepseek-flash-fast $0.02 / $0.004 / $0.16. These deployments differ from the providers' own APIs, so this page does not make a like-for-like price comparison for them, and no OpenRouter quote for these models was verified in this update. The dated competitor prices below have not been rechecked.
Side by side
| TopxAI | OpenRouter | |
|---|---|---|
| Models | 16 models on seven lines: Claude, GPT, Grok, GLM, Kimi and DeepSeek (the last three private deployments), Jev | Hundreds, from most providers |
| Token price | Claude/GPT/Grok shared routes at 50% of the listed provider reference, their official routes at 90%; the GLM, Kimi and DeepSeek models at fixed private-deployment rates; Jev $0.055 | Varies by provider, route and promotion; not always the model vendor's list price |
| Fee on top-up | None: the amount credited is the amount you enter (regional tax may be added at checkout) | Standard lists a 5.5% platform fee; payment conditions and other plans differ (pricing) |
| API formats | OpenAI Chat Completions and Responses, Anthropic Messages, Images, video, /v1/systemone |
OpenAI-style API; see their docs for what else is supported |
| Routing | Auto route picks the lowest-priced of TopxAI's own routes for the model; per-route keys pin a line | Routes across providers, with fallbacks and provider preferences |
| Prompts and completions | Relayed in memory, never stored | Their privacy page describes logging options and zero-retention routes |
| Extras | Usage log per request with route and charge; gift cards | Web search plugin, presets, app attribution, provider analytics |
| Free start | None at sign-up; every top-up earns a 3–12% bonus by amount, the first one 10% more | Free-tier models |
Current price examples
Checked on September 24, 2026 against the TopxAI price API, OpenRouter model API and the linked provider pages. The GPT-6.1 Sol comparison was updated on September 30 against its OpenRouter model page. Sonnet 5.5 was rechecked on October 2 against Anthropic's model page and OpenRouter's Sonnet 5.5 standard routes; both list $2 input / $10 output, and Anthropic lists no long-context premium. Fable 5.2 was checked on November 10 against Anthropic's pricing page and OpenRouter's Fable 5.2 page; both list $8 input / $40 output. Prices below are USD per million tokens, shown as input / output, for standard online requests below any applicable long-context threshold. They exclude platform fees, taxes, cache tokens and tool charges; Batch, Flex and priority processing are separate service tiers.
| Model | TopxAI route | TopxAI input / output | OpenRouter standard input / output | Comparison |
|---|---|---|---|---|
| Claude Sonnet 5.5 | Shared | $1 / $5 | $2 / $10 | TopxAI 50% lower |
| Claude Opus 5.5 | Shared | $2 / $10 | $4 / $20 | TopxAI 50% lower |
| Claude Fable 5.2 | Shared | $4 / $20 | $8 / $40 | TopxAI 50% lower |
| GPT-6 Astra | Shared | $5 / $25 | $10 / $50 | TopxAI 50% lower |
| GPT-6.1 Sol | Shared | $1 / $5 | $2 / $10 | TopxAI 50% lower |
| Grok 4.7 | Shared | $1 / $3 | $1.60 / $4.80 | TopxAI 37.5% lower |
The official routes sell at 90% of the provider list price. Sonnet 5.5's official route is $1.80 input / $9 output, 10% below the standard $2 / $10 comparison above. For the other Claude and GPT models above that is also 10% below OpenRouter's standard routes; for Grok 4.7 the official route ($1.80 / $5.40) is 12.5% above it, because OpenRouter sells Grok 4.7 below xAI's $2 / $6 list price. OpenRouter's GPT-6.1 Sol and GPT-6 Astra pages also list OpenAI Flex endpoints at half price; Flex is not standard routing.
These savings apply to the shared routes and comparison prices listed above, not to every TopxAI model or route. Auto routing can select a different-priced route; inspect the billed route in the usage log. Provider Batch/Flex discounts, cache hit rates, long-context tiers and retries can change an actual workload's bill. These are public price comparisons, not a paid performance or billing benchmark. Recheck the live ledgers before purchasing.
Where TopxAI is the better fit
- You use a handful of the big models and the price per token matters: on the shared pool,
claude-sonnet-5-5is $1 input / $5 output per 1M tokens against a $2 / $10 list price (model page). - You want the Anthropic Messages format, not only an OpenAI-style one, for Claude Code, the Anthropic SDK or any tool that speaks it.
- You want a fixed, published price per route and a log row per request that shows which route it took.
- You want nothing stored: no prompt, no completion, no file.
Where OpenRouter is the better fit
- You need a model TopxAI does not sell: an open-weight model, a small vendor, or the latest release before it reaches the catalogue.
- You want cross-provider fallbacks or a preference for a particular hosting provider.
- You rely on their extras: web search in the request, presets, or per-app analytics.
- Your chosen provider has a lower current price for the model you need; compare the actual route, not only the vendor’s reference price.
Using both
Nothing prevents it. Both are OpenAI-compatible, so a client that takes a base URL and a model id switches with two values. A LiteLLM or opencode configuration can list TopxAI models next to OpenRouter models under separate provider names (LiteLLM page, opencode page).
