OpenAI Models

GPT-4o

pricing: $$ input / $$$$ output
context: 128K tokens
best for: general use, code, reasoning
my rating: ⭐⭐⭐⭐⭐

the workhorse. best all-around model for most tasks. fast, reliable, good at code and conversation.

GPT-4o-mini

pricing: $ input / $ output
context: 128K tokens
best for: quick tasks, drafts, budget use
my rating: ⭐⭐⭐⭐

the budget OpenAI option. surprisingly good for simple tasks. use it for 80% of your queries and upgrade to GPT-4o only when needed.

GPT-4

pricing: $$$ input / $$$$ output
context: 8K tokens (standard)
best for: legacy compatibility
my rating: ⭐⭐⭐

mostly superseded by GPT-4o. only use if you have specific compatibility requirements.

GPT-3.5 Turbo

pricing: $ input / $ output
context: 16K tokens
best for: ultra-budget tasks
my rating: ⭐⭐

too limited for most modern tasks. GPT-4o-mini is better at similar pricing.

Anthropic Models

Claude 3.5 Sonnet

pricing: $$$ input / $$$$ output
context: 200K tokens
best for: writing, analysis, roleplay, debugging
my rating: ⭐⭐⭐⭐⭐

the best writing model available. also excellent for code review and debugging. my default for anything where quality matters.

Claude 3 Opus

pricing: $$$$ input / $$$$ output
context: 200K tokens
best for: complex reasoning, research
my rating: ⭐⭐⭐⭐

smarter than Sonnet but much more expensive. only worth it for extremely complex tasks.

Claude 3 Sonnet

pricing: $$ input / $$$ output
context: 200K tokens
best for: budget Claude option
my rating: ⭐⭐⭐⭐

the older Sonnet. still good, cheaper than 3.5. use if 3.5 is too expensive.

Claude 3 Haiku

pricing: $ input / $ output
context: 200K tokens
best for: fast responses, simple tasks
my rating: ⭐⭐⭐

fast and cheap but quality suffers on complex tasks. good for classification and simple Q&A.

Google Models

Gemini 1.5 Pro

pricing: $$ input / $$$ output
context: 1M+ tokens
best for: long documents, research, analysis
my rating: ⭐⭐⭐⭐

massive context window. feed it an entire book and ask questions. not the best at conversation or code, but unmatched for document analysis.

Gemini 1.5 Flash

pricing: $ input / $ output
context: 1M tokens
best for: fast responses, budget long-context
my rating: ⭐⭐⭐

faster and cheaper than Pro. quality is noticeably lower, but the context window is the same.

Gemini Pro

pricing: $$ input / $$ output
context: 32K tokens
best for: general use
my rating: ⭐⭐⭐

the older Gemini. mostly superseded by 1.5 Pro.

Mistral Models

Mistral Large

pricing: $$ input / $$$ output
context: 32K tokens
best for: code, multilingual, general use
my rating: ⭐⭐⭐⭐

solid all-around model. better at multilingual tasks than GPT-4o. good budget alternative for code.

Mistral Medium

pricing: $$ input / $$ output
context: 32K tokens
best for: general use, budget
my rating: ⭐⭐⭐

decent middle-ground model. nothing special but reliable.

Mistral Small

pricing: $ input / $ output
context: 32K tokens
best for: ultra-budget tasks
my rating: ⭐⭐

too limited for complex tasks. use GPT-4o-mini instead.

Mixtral 8x7B

pricing: $ input / $ output
context: 32K tokens
best for: budget open-source
my rating: ⭐⭐⭐

the open-source champion. surprisingly capable for its price.

Meta Models

Llama 3 70B

pricing: $ input / $ output
context: 8K tokens
best for: budget general use, experimentation
my rating: ⭐⭐⭐

decent open-source model. limited context window is the main issue.

Llama 3 8B

pricing: $ input / $ output
context: 8K tokens
best for: ultra-budget, simple tasks
my rating: ⭐⭐

too small for most useful tasks. fine for basic Q&A.

DeepSeek Models

DeepSeek V3

pricing: $ input / $ output
context: 64K tokens
best for: budget coding, general use
my rating: ⭐⭐⭐⭐

the budget king. 85% of GPT-4o quality at 10% of the price. my go-to for routine tasks.

DeepSeek Coder V2

pricing: $ input / $ output
context: 128K tokens
best for: budget coding
my rating: ⭐⭐⭐⭐

code-specialized version of DeepSeek. excellent for programming tasks at rock-bottom prices.

Model FAQ

How many models does NanoGPT have?

400+ as of July 2026. most are variations of the same base models (different sizes, quantizations, fine-tunes).

Which model should I start with?

GPT-4o. it's the most versatile. once you're comfortable, experiment with Claude 3.5 Sonnet for writing and DeepSeek V3 for budget tasks.

Are NanoGPT models the same as the originals?

yes. NanoGPT routes your requests to the actual model providers (OpenAI, Anthropic, etc.). you're getting the same models, just through a different API.

How do I know which model to use?

start with GPT-4o for everything. when you notice it's not great at something specific (writing, code, long documents), try the specialized model for that task.

Do new models get added?

yes. NanoGPT adds new models within days of public availability. check their model list regularly.

Can I request a specific model?

contact NanoGPT support if a model you want isn't available. they add models based on demand.
