AI models, assistants, and APIs: compare the right layer

A practical guide to ChatGPT, Claude, DeepSeek, open-weight LLMs, and BrokenGPT—what each name refers to, what to compare, and when lower-refusal access fits.

01

A model, an assistant, an API, and a gateway are not interchangeable.

Searches for “AI models” often mix underlying neural networks with consumer applications and developer services. That produces weak comparisons: a model benchmark is placed next to an app feature, or an API price is treated as evidence of reasoning quality. Start by naming the layer.

The four layers behind an AI answer
LayerWhat it containsWhat to compare
Foundation or base modelTrained parameters, architecture, tokenizer, and learned capabilities.Version, provenance, license/access, task evaluations, language coverage, context behavior.
Assistant productUser interface, system instructions, tools, memory, uploads, search, policy, and account features.Actual workflow, privacy, refusal behavior, plan limits, reliability, accessibility.
Developer APIAuthentication, request schemas, streaming, errors, rate limits, metering, and support.Supported fields, SDK fit, latency, uptime evidence, cost, observability, data handling.
Gateway or model routerA stable product/API layer that can select or wrap configured upstream models.Routing rules, disclosed identity, consistency, policy boundary, failover, markup, added cost.

BrokenGPT currently sits primarily in the assistant, API, and gateway layers. It does not claim that the configured Phase 1 foundation model was trained by BrokenGPT.

02

What the best-known names refer to.

ChatGPT is an assistant product from OpenAI. Claude names Anthropic’s model family and assistant experiences. DeepSeek publishes model and API offerings. Each can change models, plans, features, policies, and limits, so a comparison should always include a date and the exact surface tested.

OPENAI / PRODUCT

ChatGPT

Compare the selected OpenAI model and the ChatGPT plan/features separately; the product name alone is not a model version.

ANTHROPIC / FAMILY

Claude

Name the exact Claude model and whether the test used Anthropic’s app, API, or another host.

DEEPSEEK / MODELS + API

DeepSeek

Separate the published model revision from DeepSeek’s hosted API and from third-party deployments of released weights.

BROKENGPT / GATEWAY

BrokenGPT

Compare its configured public model, lower-refusal behavior, chat/API path, policy, metering, and disclosure—not an invented base-model claim.

Choose with seven questions your workload can answer.

  1. Task quality: does the exact version solve your real coding, writing, analysis, extraction, or domain task?
  2. Language quality: does it work in the languages, scripts, dialects, and code-switching your users produce?
  3. Context behavior: can it retrieve and reason over the input length you need—not merely accept it?
  4. Tools and modality: do you need search, files, images, audio, code execution, functions, or structured output?
  5. Behavior and policy: does the product engage with your lawful subject area, and is its boundary compatible with the application?
  6. Data and control: where are prompts processed, what is retained, can you deploy weights, and which terms govern output?
  7. Operations and cost: what do input, output, caching, tools, retries, latency, rate limits, and human review cost together?

A public leaderboard can help select candidates, but it cannot replace a workload test. Consumer plans and API products can also behave differently even when they share a model family because tools, system instructions, and serving settings change the result.

04

BrokenGPT fits a narrower alternative search.

BrokenGPT is relevant when a user wants fewer unnecessary refusals on lawful questions, or when a developer wants a documented chat-completions request shape with bearer keys, JSON/SSE responses, usage-based credits, and separate chat-versus-API accounting. The public model identity, context, serving state, and limitations belong in its model disclosure.

It is not currently positioned as a feature-for-feature ChatGPT or Claude replacement. The public API does not advertise every tool, multimodal, file, agent, or structured-output surface available elsewhere. If those features are mandatory, choose a product that documents them today.

When BrokenGPT is—and is not—the relevant alternative

05

Run a small, dated evaluation before making a big claim.

Build a prompt set from actual user work. Include easy cases, edge cases, long input, multilingual input, prompts likely to be refused, adversarial phrasing, and tasks with independently checkable answers. Run the same set against the exact product plan or API model you are considering.

Record enough context to make the comparison interpretable:

  • provider, product surface, model version, date, system instructions, tools, and sampling settings;
  • answer correctness, completeness, citations, refusal/deflection, security, and calibrated uncertainty;
  • time to first token, completion latency, input/output tokens, errors, retries, and effective cost;
  • language/script, reviewer qualifications, scoring rubric, disagreements, and known exclusions.

STRAIGHT ANSWERS

Frequently asked questions

01Is ChatGPT a model or a product?

ChatGPT is OpenAI’s assistant product, which can expose different OpenAI models and product capabilities over time. For a useful comparison, distinguish the ChatGPT application from the exact model and plan being used.

02Is Claude a model or an assistant?

Anthropic uses Claude for its model family and assistant experiences. A comparison should still name the exact Claude model, product surface, date, tools, context, and plan rather than relying on the family name alone.

03Is BrokenGPT an alternative to ChatGPT or Claude?

It can be an alternative for users or developers who prioritize lower-refusal chat, a documented chat-completions API, usage-based credits, and visible service boundaries. It is not an equivalent feature-for-feature replacement and does not serve OpenAI or Anthropic models by implication.

04Which AI model is best?

There is no context-free winner. Choose a dated model version and product surface, then test the tasks, languages, tool use, refusal behavior, latency, privacy terms, availability, and total cost that matter to your application.
