This model is deprecated. We still benchmark its performance, but less often: every 18 hours instead of every 6.
SpaceXAI has launched a newer release, Grok 4. We suggest considering it instead.
Grok 3 Intelligence, Performance & Price Analysis
Model summary
Verbosity
Grok 3 supports text input, outputs text and image, and has a 1M tokens context window.
Pricing for Grok 3 is $3.00 per 1M input tokens (somewhat expensive, median: $2.00) and $15.00 per 1M output tokens (somewhat expensive, median: $10.00).
| Reasoning | No This page shows the non-reasoning version of this model. A reasoning variant may also exist. |

Metrics are compared against models of the same class:
- Non-reasoning models → compared only with other non-reasoning models
- Reasoning models → compared across both reasoning and non-reasoning
- Open weights models → compared only with other open weights models of the same size class:
- Tiny: ≤4B parameters
- Small: 4B–40B parameters
- Medium: 40B–150B parameters
- Large: >150B parameters
- Proprietary models → compared across proprietary and open weights models of the same price range, using a blended 3:1 input/output price ratio:
- <$0.15 per 1M tokens
- $0.15–$1 per 1M tokens
- >$1 per 1M tokens

Frequently Asked Questions
Common questions about Grok 3
Grok 3 was released on February 19, 2025.
Grok 3 was created by SpaceXAI.
Grok 3 has a time to first answer token of 8.49s (based on SpaceXAI's API), which is at the higher end compared to other non-reasoning models in a similar price tier (median: 1.69s).
Grok 3 costs $3.00 per 1M input tokens (somewhat higher than average, median: $2.00) and $15.00 per 1M output tokens (somewhat higher than average, median: $10.00), based on SpaceXAI's API.
Grok 3 costs $3.00 per 1M input tokens and $15.00 per 1M output tokens (based on SpaceXAI's API). For a blended rate (7:2:1 cache hit/input/output ratio), this is $2.63 per 1M tokens. Pricing may vary by provider. Compare provider pricing
No, Grok 3 is not a reasoning model. It provides direct responses without extended chain-of-thought reasoning.
Grok 3 supports text input.
Grok 3 supports text and image output.
No, Grok 3 does not support image input. It can only process text.
No, Grok 3 is not multimodal. It only supports text input.
Grok 3 has a context window of 1.0M tokens. This determines how much text and conversation history the model can process in a single request.
No, Grok 3 is proprietary. The model weights are not publicly available.
Grok 3 is a proprietary model and SpaceXAI has not disclosed the model size or parameter count.
