The Complete Price Table: Every Major LLM

All prices per 1M tokens, official API, April 2026:

Frontier Models (Best Quality)

| Model | Provider | Input | Output | Cache Hit | Context | SWE-bench | | ----------------- | --------- | ----- | ------ | --------- | ------- | --------- | | Claude Opus 4.6 | Anthropic | $5.00 | $25.00 | $0.50 | 1M | 80.8% | | GPT-5.4 | OpenAI | $2.50 | $15.00 | $0.25 | 1.1M | 80% | | Gemini 3.1 Pro | Google | $2.00 | $12.00 | $0.50 | 1M | 78% | | Claude Sonnet 4.6 | Anthropic | $3.00 | $15.00 | $0.30 | 1M | 79% | | DeepSeek V4 | DeepSeek | $0.30 | $0.50 | $0.03 | 1M | 81% |

**DeepSeek V4 is the outlier.** Frontier-class quality (81% SWE-bench — highest in the table) at budget pricing. The catch: occasional outages, data routes through China, and no batch API.

Mid-Tier Models (Best Value)

| Model | Provider | Input | Output | Cache Hit | Context | | -------------------- | --------- | ----- | ------ | --------- | ------- | | GPT-5.4 Mini | OpenAI | $0.75 | $4.50 | $0.075 | 400K | | Claude Haiku 4.5 | Anthropic | $1.00 | $5.00 | $0.10 | 200K | | Mistral Large 3 | Mistral | $2.00 | $6.00 | $1.00 | 128K | | Gemini 3.1 Flash | Google | $0.15 | $0.60 | $0.04 | 1M | | Qwen3 Max | Alibaba | $0.44 | $1.74 | — | 262K | | Llama 3.3 70B (Groq) | Groq | $0.59 | $0.79 | $0.30 | 128K |

**Gemini Flash is absurdly cheap** at $0.15/$0.60 with a 1M context window. Quality is lower than GPT Mini or Haiku, but for simple tasks the price is unbeatable from a major provider.

Budget Models (Cheapest)

| Model | Provider | Input | Output | Context | | ------------------ | --------- | ----- | ------ | ------- | | GPT-5.4 Nano | OpenAI | $0.20 | $1.25 | 400K | | Gemini 3.1 Flash | Google | $0.15 | $0.60 | 1M | | DeepSeek V3.2 Chat | DeepSeek | $0.27 | $1.10 | 64K | | Mistral Small 3.1 | Mistral | $0.20 | $0.60 | 128K | | Groq Llama 8B | Groq | $0.05 | $0.08 | 128K | | Claude Haiku 3 | Anthropic | $0.25 | $1.25 | 200K |

**[Groq](https://tokenmix.ai/blog/groq-api-pricing) Llama 8B at $0.05/$0.08 is the absolute cheapest** production API. Quality is limited to 8B-parameter level, but for classification and extraction it's more than sufficient.

Price Tiers: Budget, Mid, Premium, Ultra

| Tier | Input Range | Output Range | Models | | ------- | ----------- | ------------- | ------------------------------------------ | | Budget | $0.05-$0.30 | $0.08-$1.25 | Groq 8B, Gemini Flash, Nano, Mistral Small | | Mid | $0.30-$1.00 | $0.50-$5.00 | DeepSeek V4, GPT Mini, Haiku 4.5, Qwen Max | | Premium | $2.00-$5.00 | $12.00-$25.00 | GPT-5.4, Sonnet 4.6, Opus 4.6, Gemini Pro | | Ultra | $30.00 | $180.00 | GPT-5.4 Pro |

**The biggest insight from this data:** DeepSeek V4 sits in the "mid" tier on price but delivers "premium" tier quality. No other model has this kind of price/quality dislocation.

Cost per Task: What You Actually Pay

Abstract per-million-token pricing means nothing without context. Here's what common tasks actually cost:

| Task | Typical Tokens (in/out) | GPT-5.4 | Sonnet 4.6 | DeepSeek V4 | Gemini Flash | | ----------------------------- | ----------------------- | ------- | ---------- | ----------- | ------------ | | Simple chatbot reply | 500 / 200 | $0.0043 | $0.0045 | $0.0003 | $0.0002 | | Code review (single file) | 3,000 / 1,000 | $0.0225 | $0.0240 | $0.0014 | $0.0011 | | Document summary (10 pages) | 15,000 / 500 | $0.0450 | $0.0525 | $0.0048 | $0.0026 | | RAG query with context | 8,000 / 300 | $0.0245 | $0.0285 | $0.0026 | $0.0014 | | Agent tool-use loop (5 steps) | 20,000 / 5,000 | $0.1250 | $0.1350 | $0.0085 | $0.0060 |

**10,000 chatbot replies per day:**

The 15-22x cost difference between premium and budget models is real and compounds fast at scale.

Cheapest Model for Each Use Case

| Use Case | Cheapest Option | Cost/1K requests | Quality Trade-off | | -------------------------------- | ------------------- | ---------------- | -------------------- | | Text classification | Groq Llama 8B | $0.07 | Sufficient | | Simple Q&A chatbot | Gemini Flash | $0.19 | Good enough | | Code generation | DeepSeek V4 | $0.65 | Frontier-class | | Document summarization | DeepSeek V4 | $5.25 | Frontier-class | | Complex reasoning / math | DeepSeek R1 | $12.60 | Top-tier | | Enterprise compliance required | GPT-5.4 (via Azure) | $28.75 | Premium + compliance | | Maximum quality, no budget limit | Claude Opus 4.6 | $130.00 | Best available |

**The rule of thumb:** DeepSeek V4 is the default choice unless you need (a) proprietary model lock-in, (b) enterprise compliance, or (c) maximum quality with no cost concern.

Hidden Costs That Change the Math

Price-per-token isn't the whole story. These factors shift the real comparison:

| Hidden Cost | Who It Hits | How Much | | ---------------------- | --------------------------------- | -------------------------- | | Long-context surcharge | GPT-5.4 (>272K), Sonnet (>200K) | 2x input price | | Cache miss penalty | Everyone (first request) | Full price vs 10% for hits | | Rate limit throttling | Free tiers, small teams | Adds latency, not cost | | Data residency premium | Azure (+15-40%), Claude US (+10%) | Significant at scale | | Fine-tuning hosting | Azure OpenAI users | $1,200-$2,160/month | | Support plans | Azure production users | $100-$1,000/month |

TokenMix.ai tracks these hidden costs across all providers. Check real-time all-in pricing at [tokenmix.ai/pricing](https://tokenmix.ai/pricing).

Provider Comparison: Direct vs Gateway

| Approach | Pros | Cons | | ------------------- | ----------------------------------------- | --------------------------- | | Direct API | Latest features, official support | One provider, no failover | | OpenRouter | 300+ models, free options | 5-15% markup, no failover | | **TokenMix.ai** | 155+ models, below-list pricing, failover | Third-party dependency | | LiteLLM (self-host) | Free, full control | You maintain infrastructure | | Azure / Bedrock | Enterprise compliance | 15-40% overhead |

**For most teams,** a unified gateway like [TokenMix.ai](https://tokenmix.ai) makes more sense than juggling multiple direct API accounts. One API key, one bill, automatic failover, and prices that are 3-8% below going direct.

How to Choose

| Your Priority | Recommended Model | Monthly Cost (10K requests/day) | | ----------------------- | ----------------- | ------------------------------- | | Cheapest possible | Groq Llama 8B | $21 | | Best quality/cost ratio | DeepSeek V4 | $90 | | OpenAI ecosystem | GPT-5.4 Mini | $430 | | Claude ecosystem | Claude Haiku 4.5 | $540 | | Fastest response | Groq Llama 70B | $354 | | Enterprise compliance | GPT-5.4 via Azure | $1,500+ | | Maximum quality | Claude Opus 4.6 | $3,900 |

Conclusion

The LLM API market in 2026 has a clear structure: DeepSeek V4 offers frontier quality at budget pricing ($0.30/$0.50), premium models cluster around $2-5 input / $12-25 output, and ultra-premium reasoning (GPT-5.4 Pro) costs $30/$180 for the hardest problems.

The biggest pricing story of 2026 isn't any single model — it's the collapse of the quality/price premium. DeepSeek V4 scores 81% on SWE-bench (highest in our table) while charging 8-17x less than GPT-5.4, Claude Sonnet, or [Gemini Pro](https://tokenmix.ai/blog/gemini-api-pricing). The quality gap between budget and premium models has never been smaller.

For teams running multiple models, [TokenMix.ai](https://tokenmix.ai) provides unified access to 155+ models with below-list pricing and automatic failover — one API key to compare and switch between everything in this table.
